The Best Marine Varnishes

Written by J. Harvey / Fact checked by S. Numbers

Let’s face it, we don’t give as much credit to the almost perfect combination of boats and varnishes. After all, vessels aren’t exactly cheap. They aren’t immune to deterioration as well. If there’s one solid way for you to preserve the life of your investment and even take her beauty up a notch, wouldn’t you seize it?

For my part, I can wholeheartedly say that these varnishes are great investments, especially if we’re talking about the best marine varnish. These concoctions go beyond their practical benefits, lending anything made of wood with a nice finish that only unlocks and magnifies their natural exquisiteness.

I can say as much for the products I’ve featured here. They have given me noteworthy, if not outstanding, results that make the others I’ve tried in my more than ten years of boating and fishing pale in comparison.

• Great finish
• Easy to use
• Great value for money

• Superb satin finish
• High gloss protection
• Very versatile varnish

• Easy to apply
• Excellent UV protection

If I’m going for all-around reliability and protection from sun and moisture damage, I’d choose this varnish in a heartbeat.

This is my go-to varnish for anything wood found in my sailboat. Whether it’s furniture or railing or sometimes even the bow, I often get the kind of maintainability I want every time I use this. The finish is no less attractive and only gets glittery over time in a number of my past applications.

Thinned up to around 30%, it dries quickly enough to apply multiple coats in a day. Sometimes I go for as low as 20%, down to even 5%. It’s because thinning too much does tend to backfire and lead to the varnish taking a long time to dry. It’s easy to use with everything considered.

If you want the best results, I’ve found that using a fresh foam brush with every coat would result in optimal smoothness. It may seem like a waste, buying multiple brushes, but the results are unrivaled, to say the least. I’ve had applications that lasted for a good 3 years before I needed to refinish them.

• Excellent UV and water protection
• More affordable but with high-end results
• Low shelf life

This varnish smoothly combines ease of use, beautiful finishes, and above-average durability. The winning formula for successful marine finishes for wood, in short.

This varnish is versatile in that it leaves plenty of routes open for you to take. For one, I like that they give you plenty of freedom when choosing the shine you want. It’s also available in different sizes, so I always get to buy only the proportions I deem fit for a specific project.

I have to be partial to the satin finish, though, since it delivers the exquisite luster I like to see in my indoor boat furniture and fixtures like railings. However, I always make sure to apply a high-gloss varnish if I’m working on anything that has to be exposed to the sun for long hours. That being said, I like that this product gives you both satin and gloss options.

I make sure to apply the high-gloss varnish as a topcoat, and I’ve gotten excellent results, mostly 1 to 2 years of unblemished finishes, with this practice. Sometimes, it’s shorter than that, especially on wooden areas that are more exposed to the elements. Yet, it’s protection you normally expect and can get from high-gloss varnish. In addition, it’s a varnish that’s also noticeably on the thin side, so I kind of get that it wears away faster than thicker varieties.

• Uncomplicated to apply
• Has multiple sheen and size options
• Not as durable as others

Another safe option, Epifanes marine spar varnish is anything but average with its status as a crowd favorite. Expect superior finish and durability if you choose this.

This varnish easily earns a spot here, considering its unchanging and undeniably positive reputation among boaters. Simply put, it’s hard to fault because of the wonderful results it can bring. The shiny, attractive gloss that has the Epifanes trademark is rarely surpassed by other marine-grade varnishes in my opinion.

What’s equally neat is that it’s not difficult to apply. You don’t really need to sand it with every coat, unlike the majority of other brands out there, but I still suggest you do it, especially in the later coatings. I recommend using marine spirits as a thinner with a 2:1 ratio, and take the time to pour it through a strainer to guarantee a smooth finish. At best, you’ll have to set 5 to 7 days of gradual coating to get the kind of attractive finish you want; and I mean capital-A attractive.

As in other great exterior varnishes, this product is an example to follow when imparting UV protection. At least, that’s what I think is primarily responsible for the excellent finish and the overall durability. I use this as much on my sailboat’s wood portions above the waterline and furniture as well as furnishings in my home, and the finish often lasts for 2 years on average.

• Amazing shine and finish
• Takes a while to dry
• Short shelf life

McCloskey’s Man O’War spar varnish is durable, to an almost no-brainer degree. It’s what I buy if I want to get the best out of what spar varnish offers to the average boater.

Despite its relatively hard finish, spar varnish tends to wear out faster than urethane. It’s a natural thing, so I won’t bother to list it as a con. You can’t mimic the deep amber tint, caramelization, and versatility of good old spar varnish, and this brand delivers no less than that trio of perks.

If I’m going to name a worthy brand representative of spar varnishes, I’d promptly pick this one. It adheres excellently to any kind of wood, so I generously slather any wooden fixture in my boat with this once I get a hold of a bottle.

While it’s easy to use, you’d better be prepared to invest time working with this varnish. I use mineral spirits for thinning, and I make sure to apply thin coats, starting from the middle, using a mini roller and a brush, mohair and ox hair respectively. I sand in between coats, and overall it takes time since it dries slowly.

The durability stems a lot from the outstanding UV protection. My sailboat’s wooden bow that has this finish has been battered by rain a good number of times already, and it’s still holding up after a year since the initial application. Since it’s effortless to apply, I just sand and recoat every once in a while.

• Outstanding UV protection
• Adheres to most types of wood
• Classic, eye-catching spar varnish finish
• Slow-drying
• Limited availability

TotalBoat is a household name in the marine industry as far as paints and varnishes go. This is the brand’s best offering if we’re going to consider fundamental factors like durability, shine, and value for money.

I need to stress outright that this varnish is extra thick, almost honey-like. If you don’t thin it out to at least 50%, you’ll only end up grappling with it to less than desirable results. It’s not exactly beginner-friendly with that considered, but it does pay off since you get optimal protection and the kind of shine any boat owner would be proud of.

Speaking of the finish, it begins to shine through once you hit the one-year mark. At least, that’s what I get from most of the vessels and furniture I apply it to. I can say that it’s smooth sailing once you take the time to know the right consistency.

I often use a roller and apply 5 coats then do a recoat after 2 hours in a whole day. Ideally, the last two coats should only be thinned by about 10% only. It might get tricky applying it then but, trust me, you’ll get the hang of it.

I get the results I want within a day or two — or more at times during less than optimal humidities and temperatures. Even so, that’s obviously quicker than handling traditional varnish, which takes weeks to settle. I do acknowledge the thinner’s role in helping with the drying time.

• Excellent shine and finish
• Proven durability
• Becomes easy to use with practice
• Quick-drying

If we’re talking about top-of-the-line, marine-grade durability, this one deserves to be called the best marine wood finish.

This is my favorite to use on teak because of its proven waterproof capabilities and the fact that its satin finish has just the right amount of sheen, for me, at least. It brings out the beauty of the teak and almost any wood I apply it to, for that matter, and this is coming from someone who has tried numerous marine-grade varnish before. I’ve had furniture that managed to maintain its finish for an impressive 5 years with the help of this varnish.

It’s a bit of a challenge to apply. It actually flows well enough as it is, and I rarely have to thin it with every application. However, you have to make sure that you apply it evenly with every coat and oftentimes as quickly as possible. Once I get patchy and bubbly results, that’s the only time I thin it, and I sand after the first coat, totaling up to 3 coats on average. It will dry more slowly if I thin it, though.

• Excellent durability
• Nice satin finish
• Flows smoothly without thinning
• Brings out the beauty of the wood extremely well
• Fairly cost-effective
• Not beginner-friendly

Though not marine-grade, Minwax has proven to be just as durable as many products with that label. It’s very easy to use and delivers just the right amount of shine.

I often use this on my sailboat’s furniture, and if left with no other options, even the wooden exterior of the hull and bow. It goes well with canoes, but I only tend to apply it on the ribs, rudder, and planking. While not marine-grade, it’s great for outdoor furniture, and, to me, that’s always a good sign of heavy-duty UV protection.

If I want to reinforce the protection, I only need to apply more layers, 4 coats at most but not less than 2. I’ve only used it on oak-made fixtures, though, and I get the longevity and finish I want with that kind of simple setup. The varnish lasts up to 1 to 2 years before recoating becomes necessary, with minor peeling only appearing after a year based on my experience.

I like that they give you plenty of options with regards to sheen and container sizes. I prefer satin for my interior furniture. I once made the mistake of not mixing it well and got a result that’s almost similar to high gloss. To avoid this, you need to make sure you mix it for a good 5 minutes and scrape the sides and bottoms of the can as you do so. This guarantees the soft shine you’re aiming for.

• Plenty of sheen and size options
• Decent durability
• Dries quickly
• Not exactly marine-grade

This varnish earns my thumbs up with the kind of inimitable finish it can deliver and its relatively easy application.

This has since become my favorite varnish on teak fixtures when I tried it out 2 years ago. This is because of the immense difference it makes in the way it lends my pulpit or anything made of teak with a sophisticated, good-as-new finish. It’s not overly glossy, which I attribute to the “natural teak” claim, and only darkens the wood a tad so it will still maintain its natural hues.

I’m glad it didn’t cause any yellowing, and after my second application, I can still say the same. It has a runny consistency that merits forgoing thinning on the first coat. I like to use a brush when applying it to have better control over coverage, which is great enough as it is, and all I can say is that I’ll apply this to my boat’s bow and rails the moment they start showing signs of wear.

Nonetheless, it would be pushing it to say that it’s as durable as the other varnishes here. It only took a year before my bow showed signs of peels and cracks. However, after I applied a single maintenance coat on the entire thing, I found that it limited or delayed the damage since I’ve yet to see signs again after doing a recoating. That being said, I suggest applying a fresh layer at least once a year to make the most out of this marine varnish for boats.

• Outstanding finish
• No sanding and thinning required in most cases
• Good coverage
• Minimal darkening
• Well worth the money
• A bit pricey
• Not durable

Budget-friendly, reliable, and just as good as other solid brands, this McCluskey varnish is a must for anyone choosing to go for value for money all the way.

The fact that this varnish can give you outstanding satin finishes and superb durability without going overboard in cost should give you a ready hint why a lot of boaters are shifting to this product. When I say superb durability, I mean thick coatings that you’ll be confident will last for years.

In my case, the minimum is 3 years on all my wood projects, boat bows, railings, and furniture included. You may start seeing peels and scratches here and there, as evidenced by the 7-year-old canoe that I refurbished 3 years ago. But, to me, it’s still none the worse for wear and nothing a minor recoating job won’t remedy.

The finish is not unlike the ones I get from the other varnishes mentioned here. It accentuates the natural color and look of the wood, and I’m saying this for redwood, teak, and light oak, which are the types I’ve applied it to. It dries in a day like most spar varnishes and typically doesn’t need to be thinned, though sanding is ideal per coat.

Incidentally, I need to underline the fact that this varnish is one of the few that doesn’t skin over in the can after you’ve stored what’s left of it. At least, that’s what I can say for most of the cans I’ve purchased and stored, with about a third of the can full in a year.

• Works well for most types of wood
• Superior durability
• Doesn’t skin like other varnishes
• More reasonably priced than other brands

This rarely figures in marine varnish review posts, and that’s unfortunate considering it’s another top-quality marine varnish that doesn’t yellow, imparts a glossy and thick appearance, and superb UV protection.

Usually, I use this as a general-purpose varnish for the teak and cedar parts and fixtures of my one and only yacht. It gives a deep-colored, thick, glossy, grainy, and smooth finish that I can’t get enough of. It doesn’t yellow at all, probably because of the UV additive used, at least, partly. Anyway, this is one positive quality I always like from any alkyd varnish that is done right.

I prefer to spray this one, following the 20% thinning guideline. Spraying shortens the time for full coverage. I sand lightly between coats using 220-grit sandpaper, and by and large, I only need 3 to 4 coats to get the beautiful finish I described above. It takes almost a whole day to dry, but I don’t mind since I get quality results.

As for durability, I can safely say it’s UV stable. I often leave a couple of chairs and tables out on the deck if the weather’s great, oftentimes, for an entire day. Besides a few scratches in some parts, which aren’t UV-related, they haven’t peeled yet and have maintained their shininess after 2 years since application. I can say the same for the yacht’s teak pulpit.

• Doesn’t yellow
• Superb UV protection
• Proven gloss retention

To me, this is the best boat varnish if we’re only considering durability. It also earns a ready checkmark in protection and attractive finish, making it nothing short of tough to beat.

As far as durability is concerned, the longest that I’ve seen this last without undergoing any kind of major peeling or cracking is close to 3 and a half years. It was on my favorite canoe, which I use fairly regularly for freshwater fishing. 3 years is the maximum for any exterior wood varnish for me, and without a doubt, many boaters would say the same.

I attribute most of the longevity to the excellent water and UV protection. My canoe has borne the brunt of rain and water splashes over the years. I can say the same when I expose it to extensive sunlight exposure when I go fishing in Lake Erie. Top-tier durability in my book.

I sometimes use a thinner with this varnish, but I’ve found that you don’t really need to thin it if you use an HVLP spray gun. Sure, it takes a while to dry and you have to be extra careful, but I’ll take that any day if I get to enjoy these perks and results consistently.

• Outstanding durability
• Relatively attractive finish
• Easy to apply with a sprayer
• Comes in gloss and satin varieties
• Dries slowly without a thinner

A true gem of a find, Duralux exceeded my expectations with its durability and versatility.

In almost any kind of marine varnish for exterior doors, durability and protection immediately go well together. This spar varnish proves it doesn’t belong on the back burner by delivering both. One of my canoes that I applied this on is still going strong for more than a year, and that’s a quality not a lot of products can boast of.

I’ve had varnish that didn’t take more than a month to start peeling and cracking. That’s after a fresh application, mind you, and, yes, I follow brand recommendations to a tee if I haven’t discovered a better way to apply it. This varnish has kept my other canoes shiny every time so I deemed it deserves the spotlight.

Moreover, it doesn’t yellow over time, unlike some clear varnish I’ve used before. You may argue that there’s a lot of variables when it comes to varnish yellowing, like sanding and possible chemicals it can react to. I’m not sure whether this is spar polyurethane, but I’m betting it is since that’s the only type of varnish I’ve used that doesn’t give me the yellowing effect even with minimal to no sanding.

• Satisfactory finish
• Uncomplicated application
• Doesn’t yellow over time
• Doesn’t dry quickly

Old Masters’s varnish shouldn’t be overlooked for its conveniences and quality that only a few top-tier varnish brands can bravely claim they can deliver every time.

This is among the lesser-known spar varnishes that don’t yellow even after a long time has passed. The canoe that I refurbished 3 years ago would prove as much, as it’s still holding up well, surprisingly if I might add. To be honest, this was a second option when I bought it as I didn’t have TotalBoat and McCluskey varnishes available back when I did the finishing job.

I was pleasantly surprised by how things turned out. I followed the instructions and stirred it well. It’s just the right kind of thick, to the point that I don’t have to thin it when applying with a brush or roller. I do have to thoroughly sand and clean the surface first, and it evens out nicely with every coating.

It dries quickly enough for me to apply a second coat in a single day, making me think it’s an exception among oil-based spar varnishes. At best, I give an allowance of 8 to 10 hours before brushing the next coat. Obviously, that’s a time-saving perk I’ll take any day.

It doesn’t produce a yellowing effect, even when applied to parts of my canoe that are regularly exposed to heat, sunlight, and the elements. That’s noteworthy considering it’s a clear varnish. I even have to say that the slightly weathered look it has gotten lends it a charm that most boaters would appreciate.

• Easy application
• Decent durability and finish
• Doesn’t yellow with age
• Limited to small pint-sized cans

Based on my experience, there are many “safe” marine varnish options out there. This only means you’re likely to not run out of beginner-friendly brands and can guarantee high-quality results at the same time. Whether it’s high-gloss or satin, all spar varnishes are easy to apply over new wood or previously coated surfaces. Marine varnish is also not partial to any type of wood and can accommodate those commonly found aboard or form part of a vessel, like teak, redwood, oak, etc.

However, that doesn’t completely discount the need to pay attention to certain factors when making your decision. These are usually the ones I make a note of when planning to start a varnishing job.

• Durability – I’ve found that marine-grade polyurethane is hard to equal when it comes to finishes that are guaranteed to last. Most spar varnishes pale in comparison to their urethane counterparts in this regard because polyurethane tends to last for a minimum of 3 years before re-coats are needed, based on my experience. This is why they’re great options as a marine varnish for outdoor furniture.

For spar varnishes, I’ve had finishes that only lasted a year or even less. At best, these two offer equally potent UV protection, waterproof benefits, and even resistance to scratching.

• Drying Time – Are you working with a severely limited timeframe and need to complete coats within a day? You may want to consider varnishes that dry faster like water-based spar urethane since these can dry in only a few hours. Most spar varnishes require a whole day of waiting to apply coats, assuming climate conditions are optimal.
• Ease of Use – To ensure you won’t end up throwing away your money, don’t ignore how easy or hard a specific varnish is typically applied.
• Shelf Life – It won’t hurt to pay attention to how long a specific can of varnish will last while in storage.
• Gloss – This is admittedly a largely subjective factor, but if you’re opting for high-gloss varnish, it’s almost always the one with the best durability. However, do you like your wood to be extra shiny? There are semi-gloss and satin finishes that are just as attractive, if not more, especially when used on anything wood that is below deck.

We also need to discuss the possibility of a varnish yellowing or darkening the wood that it is applied to. Sometimes, the darkening could be due to the UV additive or tint used; thus, making it unavoidable unless you opt for a different varnish brand altogether.

As for yellowing, there are ways to avoid it. I shall discuss it below, but sometimes, it’s due to the actual product as well, especially if they are clear, alkyd, or oil-based. It’s not an absolute thing, though, and there are products that prove to be exceptions to this rule.

You’ll hear a lot of experienced boaters recommending brands like Epifanes, TotalBoat, McCloskey, and Rust-Oleum. I agree with them because, to me, these brands can easily meet the standards of high-quality marine varnish. Each one has qualities where they serve to shine better, and the reviews I outlined above should give you a good idea about what they are.

Nonetheless, I’m not completely discounting the other brands I included here. I daresay that they’re just as good as those top-dog brands, especially in essential factors like durability and a long-lasting aesthetically appealing finish. Moreover, I find them to be valuable substitutes if any go-to brand happens to be unavailable and won’t even hesitate to pick them as the main option based on certain requirements of a finishing job.

Incidentally, you may have noticed that I didn’t include ease of cleaning when discussing these brands. That’s because most, if not all, of them are very easy to clean for me. At least, for the almost uniform smooth finishes that I get out of them.

There’s not much, really. When boaters use the term “spar varnish”, chances are, they’re also automatically referring to marine varnish. You can also see this in how brands usually label their products in online stores, like Sherwin Williams marine spar varnish or TotalBoat gleam marine spar varnish, to cite a few examples. If you’re using spar varnish, it’s almost always marine-grade.

Both terms give the ready connotation of finishes that provide heavy-duty protection against the harsh elements usually involved when boating, fishing, and cruising. You’ll find plenty of oil-based spar varnishes (i.e. tung oil, alkyd resin, etc.) that are imbued with additives that serve to accentuate the natural beauty of the wood, as well as solvents and other chemicals that promote fast drying and add UV protection.

Since certain varnishes have different components or are more natural or synthetic, it’s best to stick to the manufacturer’s instructions when applying any kind of varnish. However, we can’t deny that most projects share a few essential guidelines, such as the following:

• Preparation usually entails sanding between coats. The most ideal to use for this purpose is 180 to 220-grit sandpaper or even a Scotchbrite pad will do sometimes. Take note that some varnish products can do without sanding, especially for the initial coat. But, this would still depend on whether you’re applying it to a bare wooden surface or if it’s been previously coated before. If it’s the latter, then you’d most likely need to sand it first.
• Clean the dust that forms after sanding using a clean rag. I wipe it down further with a tack rag to ensure no dust or debris would still be present the moment I start applying coats.
• As for temperature and humidity, it’s best to apply any kind of marine varnish if the temperatures during the entire day don’t go above 80 degrees Fahrenheit. Humidity should be 50 to 60% or even slightly lower than that. I found that the smartest route to take is to be patient and wait for the right climate before going ahead with a project, especially if you know that it will take a number of days to finish.
• Thinning depends a lot on the product. If it’s too thick, it’s often necessary to do this, even if the brand doesn’t mention it in the instructions. The safest route for this is to follow a 2:1 varnish to thinner ratio. Mineral spirits are recommended.
• I also recommend taking the time to strain the varnish using a paint strainer to ensure a smooth finish. Sometimes, this can make all the difference in the world in getting the kind of finish that any boater would be proud of.
• As for applying coats, there are certain products that require you to start from the middle so that you can ensure an even coating. Others would caution about wiping too much, while many suggest, as is often the case in spar oil-based urethane, to make thin coats for every layer.
• Bristle brushes and badger-hair brushes are often the standard tool for application. But, again, there are products that are easier to apply with a spray or roller.

Most marine varnishes typically last for at least 2 years. There are brands that have a minimum of 3 years before they begin showing signs of damage. I can attest to marine varnish that keeps its shine and protection for 5 years, and I’ve highlighted the exact products that can achieve that.

Ultimately, if you keep its sun exposure to a minimum, you’re guaranteed to extend any kind of varnish’s lifespan. I’ve noticed that varnished fixtures and furniture in my yacht tend to last significantly longer than the ones that are exposed to sunlight extensively, regardless of the varnish’s UV-protective capabilities.

This is almost always the case considering this type of varnish is marine-grade. Most experts attribute this to spar varnish’s flexibility (i.e. its ability to expand and contract with the wood). However, equally many attribute it to the simple fact that spar varnish is mainly oil-based, allowing to wick away moisture with ease.

Now, do you have a good idea of what the best marine varnish brings to the table? With all things considered, the best parting advice I can give is to not hesitate to try out the options available to you. Sure, there will always be no-brainer choices, but it didn’t take long for me to find out that it pays to try out other brands because they may give your boat the kind of shine or longevity you’ve always wanted.

Varnishing your yacht is an essential part of its care and maintenance. The benefits are twofold: yacht varnish protects your boat from the elements, while also giving it a beautiful shiny finish. But with so many different yacht and marine varnishes to choose from, it can be difficult to know which one is best for your boat.

In this article, we’ll run through some of the most popular types of yacht varnish on the market to help you choose the right option.

What is Yacht Varnish?

Yacht varnish is an extremely durable solvent-based coating that is designed to protect the wood that yachts are made of and stop it decaying over time. Most varnishes are made up of a penetrating oil, resin and solvent. Although most yacht varnish is applied with a brush, it is possible to buy yacht varnish spray.

Different Types of Yacht Varnish Finish

There are many different types of finish to choose from, so you’ll need to know a little about them to decide which is the best yacht varnish for you.

Yacht Varnish Brands

There are various brands that produce yacht varnish. Here are a couple of the most popular:

Screwfix Yacht Varnish

Screwfix is a retailer in the UK that sells a variety of products, including hardware and building supplies. They may carry different brands and types of yacht varnish. Yacht varnish provides resistance to water, UV rays, and other environmental elements. Yacht varnishes often contain additives to enhance their durability and performance in marine conditions.

Ronseal Yacht Varnish

A durable, long-lasting marine varnish for wood that flexes with the movement of the wood and resists peeling and cracking. This varnish is slightly more pricey than the Screwfix varnish, but gets great reviews. You can buy the Ronseal brand of yacht varnish in B&Q and other retailers.

How to Varnish Your Yacht

Varnishing a yacht is fairly straightforward, if a little time-consuming. First you’ll need to carefully sand down the entire surface that you want to varnish to get it looking smooth. Then use a soft brush to wipe off any excess dust and debris, since you don’t want it getting trapped in the varnish.

Finally, use a paintbrush to coat the yacht with varnish. Leave it to dry for the recommended amount of time on the tin, then apply additional coats as required. Always check the instructions of your varnish type, and if unsure consult with an expert before starting.

Yacht varnish is solvent-based and contains toxic chemicals, which means it should not be used for varnishing animal enclosures (for example, rabbit hutches or reptile enclosures).

• What is yacht varnish used for? Yacht varnish is used for sealing and protecting wood on boats and yachts. It is also commonly used for outdoor items such as wooden doors, window frames or pergolas.
• What type of varnish is yacht varnish? Yacht varnish is a solvent-based outdoor varnish that is extremely durable. It is usually made up of tung oil and polyurethane resin. 
• What is the best varnish to use on a boat? The type of varnish that is best for your boat will depend on the type of wood your boat is made from and the finish you are looking for. Tung oil varnish is a safe bet for most boats, or you may prefer to use a one-part polyurethane varnish for added durability.
• What is the difference between yacht varnish and outdoor varnish? In general, yacht varnish dries quicker and is designed for marine conditions, so it’s likely to be more durable than outdoor varnish. However, yacht varnish is unlikely to have an anti-slip formulation, making it unsuitable for decking around the home.

Best boat varnish: 7 top options for gleaming woodwork

• Drew Maglio
• October 13, 2022

Different varnishes do different jobs. Understanding their properties will help you decide what's the best boat varnish for your woodwork. Drew Maglio explains all...

Few things are as quintessential to the archetypal sailboat as gleaming, iridescent woodwork that is indicative of a recent coat with one of the best boat varnish products on the market.

Choosing a product and methodology to apply marine varnish to achieve such results is not as simple as it would seem at first glance however, and this guide aims to make the whole process easier for novice and seasoned boat-owners alike.

First things first, what exactly is boat varnish? Put simply, varnish is a chemical solution of three parts which includes a penetrating oil, resin, and solvent.

Boat varnish for exterior use, aka. “spar varnish” — aptly named because it was designed and envisioned as a flexible protective coating to protect a yacht’s wooden spar in the harsh (outdoor) marine environment — both protects and beautifies a vessel’s wood parts.

It does so by sealing the wood with a somewhat hard, yet flexible, clear protective barrier that can last up to three years of UV and element exposure in temperate climates for the most durable two-part product formulations.

These days, most high-end boat varnishes use tung oil and an alkyld or polyurethane resin. Of the two types of resin, polyurethane — either one or two part — is going to be much more durable and resistant to UV, abrasion, fuel/solvent spills, and impacts.

While a two-part product cannot be applied over a one-part product, a two-part product is going to last much longer and be far more durable. Hence for high traffic areas like cabin soles, a two-part polyurethane product cannot be beat for longevity and durability.

Boaters should be aware that the most onerous task of applying boat varnish is the surface prep, which requires removing all flaking previous coatings by sanding, washing with solvent to degrease the surface, in addition to taping nearby areas to keep the varnish off.

Because of that, I highly recommend using quality products over cheaper, lower cost options which will mean your boat needs revarnishing far more often.

International Perfection Plus two-part varnish

Best polyurethane boat varnish

International Perfection Plus is a well-known two-pot polyurethane

International Perfection Plus (sold in the US under the Interlux brnad) is arguably the best overall marine spar varnish on the market. This two-part polyurethane formulation is not only the most aesthetically spectacular, but also the most durable and longest lasting when exposed to UV.

This two-part product is applied to bare wood after careful sanding and degreasing and can be rolled/brushed or sprayed. It uses a proprietary Interlux thinner and one’s results will be excellent if one follows the recommended procedures to the “t.”

Of all the boat varnish products on this list, this two-part product is probably the least DIY-friendly.

Reasons to buy

• Most durable marine varnish in terms of hardness and flexibility • Best UV resistance • Most beautiful (glossy) varnish if applied properly • Hardness and longevity makes it a prime contender to redo cabin soles and floor boards (after proper surface prep)

Reasons to avoid

• Difficult application for inexperienced laymen • Expensive

Epifanes clear varnish.

Epifanes Clear Varnish includes tung oil and alkyd

Epifanes offers quality marine paints and varnishes at reasonable prices and their Clear High Gloss Varnish is no exception. With 64% solids content (tung oil) and an alkyd base, this varnish is sure to be brilliant in terms of gloss with reasonable durability and longevity.

With one-part alkyd products, boat owners can expect up to two years of protection before maintenance is required if left out in the elements year-round. This product can be brushed, rolled, or sprayed.

• Affordable, quality one-part product • High solids content results in very glossy finish • Relatively easy to apply and achieve satisfactory results

• Not as much UV protection as other offerings • Not as impact or abrasion-resistant as other offerings

International Paints are also sold in the US under the Interlux brand

International Schooner Premish Varnish

A traditional marine spar varnish — albeit a good one — is Interlux’s Schooner Varnish.

With an alkyd base, 47% of tung oil solids, and UV inhibitors to boot, this product is a well-balanced one-part product that is suitable for a variety of uses. This product can be brushed, rolled, or sprayed.

• Affordable, quality one-part product • Well-balanced product in terms of UV protection and solids content • Relatively easy to apply and achieve satisfactory results

Total Boat Lust High Gloss Marine Varnish

Best value boat varnish

In recent years, Total Boat has become very popular offering products comparable—and sometimes superior—to the “big three” of Interlux, Petit, and Epifanes, at a fraction of the cost and their “Lust High Gloss Marine Varnish” is no exception. This one-part formulation uses linseed oil and a modified polyurethane base.

• Very affordable one-part proper “marine” varnish • Does not require sanding • Comes in matte for those seeking a satin finish • One-hour re-coat time

• Tends to cure quicker than most varnishes and therefore can cure before properly “flowing out” • Requires 6-8 coats

Cetol Marine Wood Finish

Best boat varnish for external teak

Cetol has been making alternative wood finishes for a long time. While this product does not have the aesthetic beauty of freshly applied gleaming varnish, it lasts far longer and stands up to UV better than every one-part varnish on this list.

When I had peeling varnish on my 1987 Ericson 38-200 sailboat moored in the tropical Florida Keys, I elected to use Cetol’s “Natural Teak” offering in lieu of varnish and found it incredibly easy to apply and long-lasting, requiring no surface prep to speak up but a quick hand sand and power wash. For outside teak, Cetol cannot be beat.

• Incredibly easy to achieve satisfactory results • Affordable • Long-lasting even when exposed to UV

• Not as beautiful as real varnish • Softer and less durable to impact/abrasion compared to most varnishes, especially polyurethane formulations

Buy Cetol Marine Wood Finish on West Marine

Miniwax Helmsman Spar Urethane

The last product featured on our list is Miniwax’s one-part polyurethane spar varnish. While not the most beautiful finish available, this product is durable (hard and abrasion-resistant), easy to use, and very affordable, making it a good choice for touching up one-part varnishes inside a boat’s cabin.

For repairing, touching up, or even redoing cabin soles, this would also be a decent budget option and therefore is included on this list. Unlike the many UV-resistant offerings on this list, Miniwax Helmsman is not very UV-resistant and therefore is not recommended outdoors.

• Very affordable, even for a gallon • One-part polyurethane enhances durability and longevity over alkyd-based products • Good for sailors on a budget needing to repair and touch up existing interior varnish

• Not as beautiful as alkyd-based marine spar varnished • Not very UV-resistant • Yellows in sunlight

Buy Miniwax Helmsman Spar Urethane on Amazon (US)

Hempel Dura Gloss

Best solvent-based boat varnish

Hempel Dura Gloss Varnish is a urethane modified alkyd, ideal for interior use

On the downside, alkyd varnishes lack resistance to abrasion and usually only one coat can be applied per day, which can make varnishing a drawn out process.

The more expensive types are formulated to speed up cure times, improve gloss retention and generally last longer.

Which type of boat varnish to choose?

Varnishing often appears to be a simple task, but there’s a bewildering choice of boat varnishes on the market, writes Rupert Holmes.

An understanding of the qualities of different types of varnish is needed to choose the optimum one for each purpose. This is particularly true for exterior woodwork which has to withstand the ravages of sun, rain and frost.

There are only a few basic types of varnish, although in many cases hybrid products are available, particularly alkyd/ tung oil and alkyd/modified urethanes that can offer a wider range of desirable properties.

Polyurethane boat varnish

Polyurethane varnishes are a harder option with good wear resistance, but they lack the flexibility of alkyds. In addition, they tend to sit more on the surface of the timber, so often do not adhere as well to the substrate, which can make them prone to flaking and chipping.

The lack of flexibility makes a pure polyurethane unsuitable for traditionally planked boats, but it can be ideal for plywood , as well as for cold moulded and strip planked hulls.

Polyurethanes are available as both one-pot and two-pot products, the latter giving a harder coating and faster cure, which allows multiple coats to be applied in one day.

N.B. One-pot polyurethane can be applied over two-pot varnish but not the other way round.

Ultra-flexible single-pot polyurethanes, such as Coelan have an elasticity of more than 300%. It can also seal cracks, is highly resistant to impact damage and doesn’t need overcoating for several years and can last twice as long as traditional varnishes.

The biggest downside is that it’s four or five times more expensive than typical basic alkyd varnishes, so up-front costs are higher, although its long term performance means the total cost difference will be smaller.

Many boat varnish products can be painted, sprayed or rolled

Tung oil varnish

Tung oil is also frequently used in traditional varnishes: it soaks in well and, although a pure tung oil product will usually cure very slowly, the final finish is very tough.

Solvent-based varnish

Traditional solvent-based one-pot alkyd varnishes are ideal for use with traditionally built wooden boats. The coating is soft but flexible, which makes it resistant to cracking when used on timber that expands when wet and contracts in dry summer weather. Additionally, the initial coats tend to soak into the timber effectively.

Epoxy resin

Epoxy resin can also be used to coat timber, but generally has poor resistance to ultra-violet light, so a varnish needs to be applied over the top. Beware inexpensive ‘yacht’ varnish sold in DIY stores – the low prices are usually easy to explain in terms of extended drying times or poor long-term performance when used outside.

Dealing with surface damage? Don’t delay!

Whatever type of varnish is used, don’t delay on sealing any areas of damage. The key priority is to keep water out, so don’t wait until you have time and suitable weather for a full repair – touch in the damaged area immediately.

This may not have a silky smooth finish initially, but don’t worry. Even if it’s a few weeks before you’re able to do a proper fix you know there won’t be any further degradation.

Top boat varnish tip

A useful tip is to clean out one of the small match pots DIY stores sell to enable customers to test household colour schemes and fill it with varnish. They have a brush built into the lid, which never needs to be cleaned, thus making a quick touch up of damage a task that only takes a couple of minutes.

Best Marine Varnish for Boats

What is Marine Varnish? Marine varnish is a finish coating that protects the outer part of the wood. Specifically, in this instance, it protects the wooden parts of a boat from the sun, rain, wind, sea spray, ultraviolet rays, chemicals, and other extraneous factors. Therefore, a marine varnish must be applied to a boat’s outer wooden parts. Therefore, for one to gain the full advantage of marine varnish, he must choose a good marine varnish product to avoid unnecessary complications that would affect the structure of the boat’s wooden surfaces. In this article will discuss the best marine varnishes to help you make the right choice when purchasing a marine varnish product. 

Some Of The Best Marine Varnishes for Boats Are:

Epifanes Clear Varnish

The “Epifanes clear varnish” is well-rounded when it comes to all the features an exterior finish should have. It is composed of Ultraviolet rays filters like alkyd resins and phenolic that would protect the outer wooden parts properly from the effects of Ultraviolet rays. Due to its components, it is easily absorbed by wooden surfaces, and its effects are long-lasting, which makes it an ideal wood varnish. In other words, it gives off a durable rock solid result. It also has a glossy finish that improves the aesthetic value of any wooden surface. 

Application of the varnish can take days because of the process involved. However, another advantage of the “Epifanes Clear Varnish” is that it takes less time to apply than the typical marine varnish, and more than three methods can be used. In other words, this particular product is very effective when it comes to the longevity and durability of wooden structures. Link to Amazon .

Total Boat Lust Marine Varnish

A remarkable feature of this marine varnish is its high glossy look, improving the aesthetic value of any boat’s wooden surface. Generally, most marine varnishes change the color of the wood it is applied on by either making it a lighter or darker shade of brown, thereby altering the originality of the wood. The “Totalboat Lust Marine Varnish” improves the wood’s original color without taking from the original aesthetic. The varnish makes the original color of the boat bolder and gives it a fresher look. 

Also, because of the varnish’s nature, sandpaper is not needed to remove materials or scratches from the wood surface because the varnish aims to improve the wood’s natural texture. Like the “Epifanes Clear Varnish,” and unlike most marine varnishes, Total Boat Lust Marine Varnish doesn’t take much time to apply because it dries fast. It can also be applied between six to eight coatings which is not difficult compared to other varnishes. A day is sufficient. 

This product is available in two different forms: the matte finish and the high gloss finish. The matte finish improves the natural beauty of the wood, giving it a bolder outlook. In contrast, the high gloss finish improves the brightness of the woodwork. The varnish is also strengthened by UV stabilizers which means that the wooden surface will be protected from Ultra Violet rays from the sun. Link to Amazon .

TotalBoat Gleam Spar Varnish

As the name implies, the “TotalBoat Gleam Spar Varnish” can be applied to almost every wooden part of the boat. It can be used for the exterior and interior parts and even wooden furniture with the boat. An excellent feature of this varnish is its versatility. It is made up of tung oil, resins, and other stabilizers that prevent ultraviolet rays from affecting the wooden structure of the boat. It is highly resistant to sunlight and its effect.

Also, it is a very unique varnish that gives off a warm effect and has a very pleasant smell that lacks harshness when applied. 

It also improves the coloring of the wood by giving it a light amber effect which improves its beauty. In other words, the “TotalBoat Gleam Varnish” makes the wooden part of the boat look and smell nice. Another valuable feature of this varnish is that it is waterproof. The importance of a boat being waterproof cannot be over-emphasized because it improves the lifespan of the boat’s wood (like a wooden deck) and prevents decay etc.

In terms of application, it can be applied in several ways. For instance, it can be applied using a brush, a roller, a spray gun, etc. This varnish comes in two forms: the gloss and satin finish. The gloss finish varnish is the preferred option for the outside wooden part of the boat because of its properties. It gives the boat depth and makes it look more solid when applied. Also, the satin varnish improves the texture of the wood, so it is great for interior woodwork. Link to Amazon .

Pettit Captain’s Varnish

Unlike the other recent varnishes, the “Pettit Captain’s Varnish” is an old brand that has been on the market for over 5(five) decades. The beauty of this product is that the new version is always better than the last. In other words, the “Pettit Captain’s Varnish” is a legendary brand that has been greatly improved over the years. As a result, it is the “experienced boater’s choice”. It has a glossy look that improves the boat’s natural beauty and gives it a bold and deep feature when applied.

It is a very durable varnish that lasts long and has been tested and recommended by boaters for decades. Also, the varnish provides UV protection on the wooden surfaces from UV rays’ effects. Like the “TotalBoat Gleam Varnish,” the Pettite’s varnish can be applied inside and out. In addition, the varnish can protect the boat from harsh weather conditions when applied properly.

As for the properties of the varnish, it is a water-based, marine-grade polyurethane gloss varnish that gives a smooth, elegant effect after it has been applied to any wooden surface of your boat. Another added advantage of this varnish is that it is eco-friendly. Most varnishes affect the environment because of their chemical elements. Also, they can impact the health of the boaters in the long run. However, this varnish is all-natural and eco-friendly, and this feature makes it stand out from the other varnishes.  Link to Amazon .

McCloskey/Valspar Spar Varnish

In a saltwater environment, the smell of the surroundings can get attached to your boat, giving it the “smell of the sea.” Although most of the time it’s nice, it can be very unpleasant sometimes. That is where the key feature of the “McCloskey/Valspar Spar Varnish” comes into effect. The varnish is resistant to water, salty air, and the smell of it. It also has a very durable finish that can last for a very long time. Also, it protects the boat from the effects of sunlight because of the UV protection present in the finish. 

It improves the wood color significantly, especially if it is an old wooden boat. If applied carefully, it can be used to hide the age of a boat, especially if the color of the wood has an old look to it. Also, it can be used for interior furniture to improve its natural beauty. It can be applied with different techniques, ranging from a brush to a roller. 

Another valuable feature of the “McCloskey/Valspar Spar Varnish” is that it is very resistant to the harsh weather environment that usually affects boats generally. Although this product is very effective, it is not advised to be applied to decks. The main reason is that it has a slippery feel to it when it’s wet, which can be very dangerous in certain circumstances. Apart from this setback, it is a very effective varnish. Link to Amazon .

Rust-Oleum 250141H Ultimate Spar

The key selling feature of the “Rust-Oleum 250141H Ultimate Spar Varnish” is that it is resistant to so many factors that can possibly affect boats in general. For instance, it is resistant to mildew, scratches, damage from UV rays, and harsh weather conditions because of its durability. It not only improves the beauty of the wooden part of the boat but is also a very effective protective coating. 

The durability of the “Rust-Oleum 250141H Ultimate Spar Varnish” is outstanding compared to other varnishes. It can also be used in the interior parts of the boat in places like doors, interior floorboards, etc. It can also be cleaned frequently with soaps and detergents. The “Rust-Oleum 250141H Ultimate Spar Varnish” has three finish options: satin, gloss, and semi-gloss, which is unique because you can use any depending on your taste and what you want.

Also, most marine varnishes rarely have above 2 finishes. This clearly differentiates the “Rust-Oleum 250141H Ultimate Spar Varnish” from other varnishes.  Link to Amazon .

The Best Marine Varnishes for 2024

Boats often come in contact with a lot of different pressures such as waters, rocks, and even animals. On top of this, it is also exposed to the sun’s harmful UV rays all of the time. With this, the need for marine varnish became extremely popular among boat owners. It is actually one of the most effective things that any boat owner can do to preserve the beauty of their boat.

However, it is not that easy to find the perfect marine varnish that will work wonders for our boats. We have to experience a lot of trial and errors before we finally find what specific marine varnish is best for our lovely ships.

Do you want to keep your boat as pristine as possible? Read on to know about the top 10 best marine varnishes!

1. Rust-Oleum 207008 Marine Spar Varnish

2. epifanes clear varnish, 3. totalboat lust marine varnish, 4. system three 1855s16 marine spar varnish, 5. minwax 630500444 helmsman spar urethane, 6. interlux iva316/qt cetol natural teak varnish, 7. mccloskey man o’war spar marine varnish, 8. old masters 92304 spar marine varnish, 9. pettit captains varnish, 10. interlux y60/pt goldspar satin varnish, who is this for, factors to consider when buying a marine varnish, advantages and disadvantages of using a marine varnish, care and maintenance, frequently asked questions, best marine varnish reviews.

I was so stunned by this beautiful marine varnish! When I received it, I could immediately tell that it will perform amazingly. I sincerely appreciate that the company made sure that the application process will be easy! All I needed was a foam paintbrush to apply it on my boat’s surface and a good quality sanding sponge to smooth out the wood surface for a clean and even coat.

Unlike other varnishes, the company advises its customers to skip the thinner before using this product because it will affect the varnish’s performance by prolonging the drying time and increasing the chances of bubble formation.

Now, the most notable thing that I love about this product is that it dries so quickly! After the 1st layer that I applied on my boat, it only took roughly 2 hours for the spar varnish to dry. I am so flabbergasted because it was so convenient to use!

I love how I did not need to wait for at least 12 hours just to apply the 2nd coat of this marine varnish! This is such a good deal because not everyone has the time to let the varnish sink in. Although, you still have to sand the boat before applying the 2nd layer of varnish so that your application will glide as smoothly as butter!

As an oil-based marine varnish, it is better than a water-based marine varnish because it provides a more vivid color with a shine that does not look dull! Even though it is a little bit runny, its consistency does not affect its performance because it is oil-based. It sticks to the wood more comfortably, which is actually one of the reasons why it dries quicker!

• It does not require a thinning agent.
• Even application
• A quick drying time of 2 hours
• Can do two coats in one day
• Vivid and shiny
• It has a runny consistency

I have nothing to say but outstanding! I cannot get over the fact that this marine grade spar varnish performs exceptionally well. I am so excited to use this on my other boats because I’m sure that it will provide the perfect coating for protection and aesthetics!

First of all, I love how this product does not smell too strong! That’s one of the many things that I love about this epifanes marine spar varnish. Because of my countless attempts at finding the best spar varnish, I know how stinky some varnishes could be. It really is a hassle because some products have strong smells that give me a headache.

But this one was delightful to use because it almost does not have a strong chemical smell! I spent a lot of time using this spar varnish, and I can safely say that I did not experience any headaches.

I used a thinning agent before the first coat for this varnish because this product’s consistency is quite thick, almost similar to a syrup’s texture. Doing this resulted in a deep, high-gloss, and smooth finish! I cannot get enough of how beautiful the finished product is.

The company recommends a total of 8 coats, but I achieved my desired deepness and intensity with just five coats. Because of this, I have enough left varnish left for future use, which I sincerely appreciate!

I especially love that this product gives off a dark amber color. I prefer this type of finish because it made my boat look rustic yet fresh at the same time! And because it is on the darker side, it can cover old stains that may be present on your boat, so technically, it is a varnish and a light paint in one!

The wood on my boat started to look really nice once the spar varnish has dried. At the end of the day, it looked brand-new and ready to take on the fiery waters!

• It does not smell too strong.
• It did not give me headaches due to the chemical scent.
• Thick consistency
• Varnish and paint in one
• The recommended number of coats is 8

I think that is such a steal! For just half the container, I was able to apply five coats, and my boat looked very beautiful instantly. If I were you, I would get my hands on this beautiful spar varnish!

I received this totalboat gleam marine spar varnish; it was love at first sight! I immediately started to use it, and upon the initial application, I love how it enhances the woodgrain feature of my boat. Unlike other spar varnishes, this one does not try to eliminate the texture of wood; it makes it look more pleasing to the eyes!

Another thing that made my heart fall for this varnish is that it does not require the use of a sanding sponge or sandpaper. As I said, it aims to enhance the wood’s texture, so there is no need to even it out.

I also enjoy how with just six coats, I was able to finish varnishing my entire boat in one day. This made me fall head over heels for this product!

I also appreciate that this product features a slight tint that improves the overall design of the boat. No, it does not entirely cover up the boat’s original color; it makes the actual color brighter and more alive. I have had some experience with varnishes that dulls down the boat’s original hue, so I am happy that this one does not do that!

Lastly, the company offers two different types of varnish – one matte and one high gloss. Personally, I prefer a high gloss spar varnish because it lessens the appearance of scratches. However, some people enjoy matte varnishes, so kudos to TotalBoat for providing boat owners such as me with options!

Although it is quite thick, and I had to reapply varnish on some parts because, for some reason, the material does not adhere to it, I was still left with a beautifully-varnished boat at the end of the day!

• Improved my boat’s woodgrain texture
• It does not require sanding.
• Enhanced the color of the boat
• It has two different kinds of varnish
• I had to reapply varnish on several areas

To sum it up, I am so glad that I was able to try this product! For such a long time, I have been looking for the varnish that has a perfect balance between tint and gloss, and I finally found it in this product!

Upon receiving the product, I ordered both variants: satin and high shine. I decided to combine the two types of finish to get a more solid hue without losing the varnish glossiness.

I think I made the right decision! The end product is exceptionally smooth, glossy, and stable at the same time. I love how it is as soft as a baby’s butt… maybe even softer!

Because its consistency is quite thick, I used an HV/LP sprayer to apply it. This product applies like a dream. I’ve never used a marine varnish as smooth as this before. Therefore, the use of a thinning agent is totally necessary since it is viscous.

I also find its consistency to be quite thick. I love how this product really gave me the option to have my varnish on the thicker side or on, the thinner side. Well, I opted to thin it out a little bit using a thinning agent.

I love how it applies! For me, I would not use a bristled paintbrush with this product because there is a chance for bubble formation and streaky application. So, I used an HV/LP sprayer to apply it, and I honestly did not get tired at all!

I got so excited because I have never used a marine varnish that was as smooth as this before! I personally prefer mixing it with a thinning agent for the sprayer, but if you want it to be thicker, you may want to use a new paint roller to do the job.

Even though this does not dry as quickly as the other spar varnishes I have tried, I think those good things really do come to those who wait. As I used this product, I learned to be patient and to keep on trusting the process.

In the end, I got the best-looking boat ever! On top of that, this one also has superior saltwater protection for my boat. I can honestly tell you this: I think this is such a great deal!

• Available in satin and high shine
• Thick consistency for fuller application
• Best used with a paint sprayer
• Saltwater protection
• Excellent finish if both variants are mixed.
• Long drying time

Honestly, I think I got such an excellent deal with this product. This could easily be the best marine varnish UV protection!

This one is for the boat owners who prefer marine varnishes without any tint! This product from Minwax is a water based marine varnish, and this means that it is a clear gloss that does not have any color to it.

I love how this could be used on top of colored boats. Since it does not alter the existing shade that the ship has, this is a good option for those who prefer to maintain the current color, brightness, and contrast of their boats.

Its consistency is thin, mostly because it is water based. With this, I used a paint roller. I got the most seamless application because a thin consistency goes well with a roller! I am in awe that I only had to use a sanding sponge or sandpaper before applying the first coat. The succeeding layers did not require any sanding because they glide on like a dream!

Overall, it took me a total of 4 coats to get an excellent finish. However, I added an extra layer to be sure that the end product will be as beautiful and vibrant as possible.

I love how to apply this even over latex paint, unlike other varnishes with spar polyurethane as an ingredient.

This goes to show how dedicated the company is to provide us with quality products that won’t be inconvenient to use.

The only issue that I came across is that it tends to crack whenever I suddenly apply too much. I was able to remedy this by ensuring that each layer is skinny to avoid any separation of the varnish.

• It does not have a tint
• It does not affect the original color of the boat
• It can be used over latex paint
• It has a tendency to crack if too much is applied
• Thin application per layer is needed

This one is indeed a tremendous marine varnish to let the right color of your boat shine through. I highly recommend this beautiful marine varnish!

I have to say that this product is a rare breed! There are two common types of marine varnishes, and these are the high gloss and the matte variants. It is uncommon for the market to offer a satin varnish. Satin is a cross between a high luster and a matte finish; it has a shine, but it is also relatively flat. Basically, it is the best of both worlds!

My boat is made of a wood called teak. Honestly, I believe that this product from Interlux is the best marine varnish for teak! I did not have to use any unique tool to make it look splendid. No thinning agent and sandpaper had to be used because this boat varnish already does a great job in penetrating teak and, honestly, other types of wood effectively!

This product has a golden hue. It is the perfect shade for my boat’s wood! I love how it made my boat look expensive and well-kept. It also has a knack for giving a boat its personality!

I was able to see it personally because my boat’s color has already faded. But soon after applying this boat varnish, its color started to come alive! It slowly became brighter and radiant. Suddenly, my faded boat transformed into a beautiful ship with a rich and deep copper hue.

Even though this product can only be applied right above the waterline both for interior and exterior portions of the boat because it is not effective against saltwater, it is still not a bad deal because this varnish is not only useful for boats. It can also be used as an alternative for tables, chairs, and doors!

• Satin finish
• Penetrates teak effectively
• It has a golden hue
• Alternative varnish for tables, chairs, and doors
• Only useful above the waterline
• Not effective against harsh saltwater

Because of the fantastic quality that this product offers, I simply cannot get enough! I’m sure that I will be using it again soon for my other boats.

This marine grade spar varnish proves that a boat undergoes a lot of adverse conditions both while sailing and while being stored. As a varnish, I love how this product is very well-versed when it comes to being durable!

I am so amazed because it does not peel easily, unlike other marine varnishes that I have used in the past. It stays put for a long time, and it does not crack. It is very different from polyurethane-based varnishes because this one from McCloskey/Valspar screams flexibility. It has the power to adhere onto various surfaces, and it sinks deep into the wood quite decently.

It is made with tung oil instead of urethane. It can be seen as old-school because it does not have the synthetic material that modern varnishes contain, but whoever said that old-school is terrible? Actually, tung oil is useful, and it gives off a beautiful finish!

I specifically go crazy about this product because it is thick and pigmented enough to provide a certain degree of coverage. I love that it is useful as a corrector; it completely covers the tiny scratches and stains on my boat’s surface!

But still, this product is not advised to be applied on decks. It is a high gloss varnish, so when it gets wet, there is an excellent chance for the surface to become extra slippery. To avoid accidents on the deck, I decided to apply a matte marine varnish instead.

• Extremely durable
• It does not peel and crack easily.
• Flexible; can be used on different surfaces.
• Made with tung oil
• Thick and pigmented
• Can cover stains and scratches
• It can’t be used on the deck
• Slippery when it gets quite wet

For me, I will still go for this product even though I can’t use it on my deck. It gives some of the best gloss that I have seen, and it is very durable!

What a beautiful product! All I can say is wow! This marine varnish is quite exceptional! This company really is the Old Master of the varnish industry. The sun is known to be a catalyst for the faster aging process of wood and paint, which results in brittle and faded-looking boats.

I am so happy that I have this product, which is perfect for absorbing the sun’s harmful UV rays, so it worked well as my boat’s exterior marine varnish! I love how it can be used above and below the waterline so I could still protect the bottom half of my ship from fading quickly.

Although this product works well as exterior spar varnish, I am in awe because it is also useful as an interior varnish! Because of its satin finish, the deck would not feel slippery even when the area is wet. I love how the safety of all riders is guaranteed because of this varnish!

However, it took me three days to finish the entire application process because the drying time took 5-8 hours per each coat. But even though the process took quite some time, I was not disappointed with the result that I got!

After patiently applying eight coats, I was left with the most marvelously looking boat! It seemed very mysterious; not too shiny, not too matte. Now, my boat has the perfect coating!

• Absorbs the sun’s harmful UV rays
• Perfect as an exterior marine varnish
• It can be used below the waterline.
• Also great for interior portions of the boat
• It prevents boat aging and fading
• Not too shiny, not too matte
• The drying time is 5-8 hours per each coat

Because of this product, I am so glad! I was left with a good-looking and well-protected boat. I could not ask for more!

I am so happy that this product is a water based marine polyurethane varnish. It can be challenging to find a glossy varnish that is water based because most glossy varnishes are oil based. Because of this, I am always on the hunt for a water based product that is a high gloss, and finally, here it is!

I love that this product is exceptionally eco-friendly because it does not contain VOCs or volatile organic compounds, which can be harmful. Varnishes usually release these, and long-term exposure to these chemical compounds can result in long-term health effects.

I am so relieved to finally see a marine varnish that does not negatively affect humans and species that reside in water. I love how this company went the extra mile just to give us a healthier alternative to the usual varnish formula that we get in the market!

Another reason to stan this product is its exceptional clarity! Upon using this, I could immediately say that it produces a very smooth, flexible, and clear varnish. I am so happy because I did not have a hard time applying it on the boat.

I really like how this varnish was able to encourage the improvement of my boat’s woodwork! It did not weirdly interact with the ship, and it actually sank into the wood utterly. This is one of the best features of this product!

Now, let me tell you about its leveling property! This is the smoothest and most even varnish application I have ever experience. I love that it glides on smoothly and allows room for error. You can go over a wet varnish as many times as you want!

• High gloss, even though it is water based.
• Eco-friendly
• It does not produce volatile organic compounds.
• It does not pose harmful health problems.
• Exceptional clarify
• Improves woodwork
• Amazing leveling property
• Allows room for error during application

As a water based varnish, I cannot believe that this is as amazing as it is! If I were you, I would stock up on this product, especially if you have multiple boats!

Indeed, a fantastic product! This marine polyurethane varnish gave my boat an amazingly bright and lively hue. I love how it did not change my boat’s color; it only brightened it up by introducing a nice sheen on top of it!

For this one, I decided to use a bristled paintbrush because it made the application smoother and more even. It went on in a more uniform layer, which makes layering seamless and effortless! Even though it has a thick consistency, it works well with a brush. I love how it did not form any air bubbles!

Because it is quite thick, the drying time is kind of long. I applied it for a total of two days, and on the first day, when the temperature was low in humidity with excellent air circulation, each coat was able to dry for just 5 hours. However, the weather was a little more humid on the second day, and each coat dried for 7 hours.

I love how hard this product is once it is dry! Because of its thick consistency, it was able to cover my boat’s surface better than other marine varnishes. It can resist stains, scratches, and other minor physical damages that roaring waters and sharp rocks can cause. I love how I can be assured that my boat will look its best even when I sail rough waters!

When I started to check how it feels inside the boat, I was taken aback because it did make a huge difference! I thought that the interior had a new coating, but it did not feel slippery at all. I can assure you that this marine grade varnish for wood is very useful in providing a safe surface for passengers!

I am quite disappointed with this because obviously, one of the main reasons why we, boat owners, invest in great marine varnishes is because of its UV protection. Although this product offers a great sheen and exceptional thickness, it, unfortunately, cannot prevent the boat from aging and fading.

• A modified version of polyurethane
• Did not form any air bubbles and streaks
• Thick consistency offers excellent protection.
• Resists stains, scratches, and other minor physical damages
• Not slippery
• It does not have UV protection.
• It can’t protect my boat from aging and fading.

I am very fond of this product. I can see myself using it more in the future, although it will work best as an interior marine varnish!

The marine varnish is for people who are passionate about improving their boats’ appearance. Other than that, it can also be used as a substitute for the typical varnish that is used for daily materials such as doors, windows, chairs, and tables.

Boat Owners

The marine varnish is for boat owners because they take pride in their boats’ beauty and maintenance . Boat owners need to apply marine varnish on their ships because it protects the wood against the rigorous events that take place while sailing.

Marine Artists

Marine artists also need marine varnish because they are responsible for doing the dirty work that most boat owners prefer not to do. They get paid to paint, design, and apply varnish on boats so that the wood is protected and well-maintained.

Varnishing is an essential aspect of carpentry because it strengthens wood. It provides a protective layer between the wood and the outside world, which could pose harmful threats to the wood.

Marine varnish, sometimes referred to as spar varnish, is a term that is quite famous in the boating world. This specific type of varnish is a finish specially designed to protect boats from the harsh conditions they experience during sailing. It is one of the essential materials that a boat owner has in their arsenal of boating essentials.

There are a lot of different options when it comes to purchasing a marine varnish. Here are some of the best features that you might want to consider before buying one:

UV Protection

This is the main reason why marine varnish was specifically made is for it to act as a UV blocker against the sun’s damaging UV rays. As you shop for your next varnish, it is vital to make sure that you are getting one that has the best marine varnish UV protection because it will help to prolong your boat’s life.

Remember that a protected boat will always remain on top of its game. It will not age, fade, and get damaged easily.

High Gloss, Satin, or Matte

There are three different finishes that marine varnish comes in:

It will make your boat appear new and shiny. This variant is best used for the boat’s exterior area because it tends to become too slippery if used inside the ship. Accidents may happen, such as accidental slips, which could result in harmful injuries.

As you can tell, this finish is entirely flat and free of any shine and gloss. This is the best choice for your boat’s interior area because it will provide you and the passengers the perfect surface texture for walking and standing.

This finish is perfect for both exterior and interior portions of your boat. It has a sheen, but it is not too glossy. It is a fusion between a high gloss and a matte, which leads to a perfect finish that is suitable for any boat.

Tinted or Untinted

A tinted marine varnish has the capability of slightly altering the original color of your boat. It will most likely produce a more resonant tone that will complement the color of your boat’s wood. Usually, oil based marine varnishes have tints.

Basically, this form of marine varnish does not have any color to it. If you prefer to maintain your boat’s paint but you want to add some gloss and protection to it, you may opt for this variant. Typically, water based marine varnishes are untinted.

Oil Based Or Water Based

As mentioned above, oil based marine varnishes have a tint to them. It could be amber, golden, or a rich copper tone. As time passes by, rest assured that your boat’s tint will get more prosperous and more profound.

I like this type of marine varnish because it does not try to hide the wood grain of the boat. It actually aims to improve its texture, not cancel it out. It is also essential to take note that oil based marine varnishes are glossier if compared to water based marine varnishes.

Water based

This base has no color at all; it is transparent. It only provides gloss because it does not affect the original color of the boat. However, this has the tendency of flatting out the wood grain of a vessel.

Again, take note that even though water based marine varnishes are still quite glossy, it is still less glossy than oil based marine varnishes.

Marine varnish’s sole purpose is, in simpler terms, to protect the boat from aging. It can block the sun’s UV rays, which can slowly but surely deteriorate the wood’s quality and color.

Most marine varnishes in the market nowadays are effective in protecting the wood against harmful light. This will ensure the boat owner that their boat will maintain its quality for an extended period of time.

Aesthetically Pleasing

The varnish is used to enhance the wood’s appearance. It provides shine and evenness across the entire wood surfaces. It reduces the wood’s porosity by sealing each area; it penetrates the wood without damaging it. It also keeps tiny wood parts in place to avoid woodcut incidents.

Covers Micro Tears, Scratches, and Stains

Marine varnish can also serve as an additional cover over micro-tears, scratches, and stains. Even though your boat has some scratches, rest assured that a few coatings of the best boat varnish will thoroughly cover it up. Also, it is thick enough to resist minor physical damages.

Disadvantages

Slow Drying Time

Some, not all, marine varnishes tend to dry slowly. So instead of getting the job done within a day, you might have to work for 2 to 3 days just to finish all of the needed varnish layers.

Can Contain VOCs

Most marine varnishes nowadays contain Alkyd or Polyurethane synthetic products. Although they provide excellent results for applying and retaining the varnish onto boats, they produce high amounts of VOCs or volatile organic compounds.

VOCs are gases that Alkyd and Polyurethane emit into the air. It is associated with the formation of cancer within the human body. It also has the capacity to interact with other forms of gases, which could result in both short-term and long-term health issues.

Some other health issues that volatile organic compounds pose are the following:

• Irritation of eyes, nose, and throat
• Dizziness and headache
• Memory loss
• Visual impairment
• Sick building syndrome

Clean Before and After Sailing

As a rule of thumb, always clean your boat’s surfaces before and after sailing . Not only will it make sure that your varnish is well-kept and beautiful-looking, but it will also lengthen the life of your boat.

While cleaning, do your best to get rid of all sorts of grime and dirt. Check both the interior and exterior. It is also a smart choice to do a thorough cleaning at least once or every two weeks. Not only will it keep your boat hygienic, but it will also make your boat maintain its best shape.

Apply New Varnish If Needed

Yes, you have fully applied marine varnish on your boat’s surfaces. However, you need to check for the need to reapply every now and then. Keep in mind that it is always better to prevent damage rather than to repair it.

By doing a monthly check-up, your boat’s safety and elegance will always be assured. If you can see certain varnished spots that have thinned down, reapply several marine varnish coats onto that area to avoid the promotion of wood brittleness.

Where can I Buy a Marine Varnish?

There are a lot of different places where you can purchase a marine varnish. Here are some of the most common establishments where you can find the best marine varnish for your boat:

• Hardware stores
• Department stores
• Ship’s stores
• Marine stores

Can a Marine Varnish be used on a Deck?

Yes, you may use a marine varnish to enhance your deck’s beauty and UV protection. But make sure to choose a matte or satin marine varnish so that the deck would be safe to walk on. Avoid using high gloss marine varnishes because they will be too slippery to walk on and may result in unwanted accidents!

Does a Marine Varnish Effectively Waterproof a Wood?

In a way, it does provide a non-porous layer between the wood and the outer area. Think of marine varnish, especially polyurethane marine varnish, as a thin plastic that clings onto the wood. If you put in enough oceanic varnish layers, you will successfully get rid of any porous areas, directly waterproofing the wood.

In a nutshell, every boat owner has to have a little bit of knowledge on marine varnish because it is one of the most effective ways to preserve a boat’s health. With just one session of marine varnish application, their craft will be protected for a long time.

The marine varnish is essential to protect boats from getting older instantly. As much as possible, we have to do our best to take good care of them because, let’s face it; they cost quite a lot! This list of the best marine varnish of 2021 will surely give you some ideas about which varnish to purchase!

Which Yacht Varnish Is Best For My Boat?

Yacht varnish is a specialized type of varnish that is often used on boats. It has several advantages over conventional varnish, which is why it is becoming more and more popular among boat owners. In this guide, we will discuss the benefits of yacht varnish. We will also answer some common questions about yacht varnish. So if you are interested in learning more about this topic, keep reading!

Yacht varnish is a type of varnish specifically designed for boats. It is typically made from a tougher resin that can withstand the harsh conditions that boats are exposed to, such as salt water and sunlight. Yacht varnish also often contains UV inhibitors to help protect the wood from fading and other damage caused by exposure to sunlight. Conventional varnishes are not as durable as yacht varnish and will not stand up to the same conditions. This makes them less suitable for use on boats. However, they can still be used for other applications, such as furniture or around the garden.

Which types of varnish to use on my boat?

Marine varnish can be divided into three different types, each with its own perfect uses. Yacht owners choose to use one or all of these types for better performance.

Tung Oil-based varnish 

Is the most popular type among yacht owners who take boat maintenance seriously. International Schooner or Goldspar Boat Varnish are both oil-based varnishes that coats the wood evenly leaving a smooth finish while requiring minimal preparation work before it can be applied. This only requires a couple of coats. Is advisable to lightly sand the surface between coats to achieve the highest quality glossy finish. The smooth, high gloss finish will protect teak parts from water stains and help to maintain their appearance over time! Its UV protection helps prevent mould growth too which is especially important in wetter climates. Oil-based varnish is easy to apply and can be repaired by sanding and re-oiling the wood, meaning it will last longer than other conventional varnishes. It's also easier to apply compared with water-based yacht varnish which requires no sanding or priming before application.

Water-based boat varnish

Often used on marine boats where there is not much exposure to agitation or rubbing, making oil-based varnish too heavy for use. This yacht varnish type tends to leave a thin, powdery residue that needs sanding down after drying but offers better penetration into the wood than its oil counterpart. Polyurethane boat varnish - is much more hard-wearing than oil or water-based yacht varnishes. Stronger than oil-based or water-based yacht varnish, polyurethane yacht varnish tends to dry quickly and offers an ultra-hard surface that is resistant to impact, scratching and denting. This yacht varnish type has a high gloss tough finish so it's best suited for areas of the boat that are exposed to more wear and tear. This type of varnish can also be divided into two categories as one part polyurethane boat varnish and two-part polyurethane varnish.

One Part Polyurethane Varnish

The yacht varnish that is most commonly used for yacht paint jobs. The yacht varnish offers a quick drying time and can be easily re-coated within hours between each coat. It should be noted that due to its rigidity it is not recommended to be used for painting highly flexible wooden areas as it might crack in time leaving the wood exposed to elements. Two-Part Polyurethane Varnish - is the varnish with longer working times, making it easier to apply on larger boats. It's advisable to use only one part polyurethane yacht varnish for smaller projects as two-part yacht varnishes tend to leave an unprofessional finish when applied by hand. This type of varnish is extremely tough and consists of two products mixed together. It offers very good protection from moisture and UV damage but the same as the above this is not suitable for some areas on your yacht (such as spars) and it will crack as the wood moves and will leave the wood exposed to the elements.

Is yacht varnish waterproof?

Yes, yacht varnish is typically waterproof. This makes it a good choice for protecting boats from the elements. It can also help to keep the wood of the boat looking its best for longer.

Does yacht vanishes need a primer?

No, yacht varnish does not typically need primer. However, it is a good idea to test it on a small area of the surface you are going to varnish to make sure it adheres properly. If you do decide to use primer, make sure it is designed for use with yacht varnish.

Does yacht varnish seal wood?

Yes, yacht varnish seals the wood. It forms a protective barrier that helps to keep the wood from damage and keeps it looking its best for longer.

How long does yacht varnish last?

The lifespan of yacht varnish varies depending on the brand and the conditions it is exposed to. However, it typically lasts for several years, anywhere from two to three years before you need to apply a new coat or two. Some varnishes obviously last longer than others depending on the area where they will be applied.

Which is better? Woodstain or yacht varnish?

There is no simple answer to this question as it depends on the specific application and the needs of the user. However, in general, yacht varnish is a better option for protecting wood from the elements and keeping it looking its best. It is also typically more durable than wood stain, which makes it a better choice for boats.

Why is it important to sand between coats?

It is important to sand between coats of yacht varnish because it helps to create a smooth, even surface. This makes the final coat of varnish look its best and helps to protect the wood from damage.

How many coats should I apply?

The number of coats you should apply depends on the specific product you are using and the area you are varnishing. In general, two to three coats are sufficient. However, it is always a good idea to follow the manufacturer's instructions for the best results.

What type of finish can you get?

There are three types of finish on boat varnish: gloss, semigloss, and satin. Each one has its own benefits and drawbacks, so it is important to choose the one that best suits your needs. Gloss finish is the most durable, but it is also the most reflective. This can make it difficult to see in bright sunlight. The semigloss finish is less reflective than gloss, but it is still quite durable. It is a good choice for areas that receive moderate amounts of sunlight. The satin finish is the least reflective and also the least durable. However, it can provide a more natural look to the wood. It is a good choice for areas that do not receive a lot of sunlight.

Can you paint yacht varnish over wood stain?

Yes, you can put yacht varnish over the wood stain. However, it is important to make sure that the stain is fully dry before applying the varnish. Otherwise, you may end up with a sticky mess.

How long does it take for yacht varnish to dry?

The drying time for yacht varnish varies depending on the brand and the conditions it is used in. In general, you can expect it to take anywhere from six to eight hours to fully dry. However, it is always a good idea to read the manufacturer's instructions for the best results.

Can you thin yacht varnish?

Yes, you can thin yacht varnish if it is too thick. However, you should only use a thinner that is specifically designed for use with yacht varnish. Otherwise, you may end up with a poor-quality finish.

What is the best way to remove yacht varnish?

The best way to remove yacht varnish depends on the type of finish you have. If you have a glossy finish, you can use a polishing compound. For a semigloss or satin finish, you can use sandpaper. In general, it is best to remove yacht varnish with a power sander. However, you can also remove it by hand if you are careful.

Can I apply a new coat over the existing varnish?

Yes, you can apply a new coat of varnish over the existing varnish. However, it is important to make sure that the old coat is in good condition. Otherwise, you may not get the desired results.

Does yacht varnish go yellow?

Yacht varnish is designed to keep your boat looking good as new even throughout the season's hottest and coldest temperatures. The UV inhibitors prevent yellowing, which can otherwise occur due to exposure to external factors like sunlight or rainwater on a dock; they also remain slightly soft so that it will not crack when expanding or contracting with changes throughout each year. Liquids such as engine oils may cause blistering if left unprotected by an anti-blister agent like silicone lubricant (which contains graphite).

Is yacht varnish oil or water-based?

Yacht varnish is typically oil-based. This makes it more durable and resistant to fading. However, water-based varnishes are also available. These are less durable but easier to apply.

So which yacht varnish is right for you?

Choosing the right yacht varnish depends on how much time you want to put into maintaining your boat as well as its location. We stock a wide range of varnish suitable for any type of wood on your vessel.

2. paintmaster trade yacht varnish, 3. rustins satin yacht varnish, 4. epifanes clear high gloss yacht varnish, 5. ronseal satin exterior yacht varnish, yacht varnishe reviews.

Originally based in London’s Shoreditch area in the heart of the furniture making industry, Rustins know a thing or two about making the best exterior varnish for wood. We knew we had to try out their yacht varnish , so we got hold of a tin and put it through its paces.

It’s developed to give a durable finish to exterior timbers, with added tung oil that dries to a high shine. We love the almost wet look you get from this product, it’s the best satin yacht varnish we’ve used so far.

With a strong tradition of boat building and high expectations from their protective coatings, you can count on Dutch specialist paint manufacturer Epifanes to create the best yacht varnish. And they’ve been doing so since 1902.

We really like their High Gloss Clear Varnish , it’s not the cheapest option but you certainly get what you pay for. Designed for use on boats, it uses a blend of tung oil and resins to build up an ultra-tough and glossy surface that will protect your wood surfaces for years, whatever the weather.

Varnishing Perfection

Advertisement

Want to be the envy of the marina? Here's how to add a breathtaking finish to your brightwork.

Varnish on a warm day — early in the morning, if you can — and the varnish will have a chance to dry before the evening dew can damage the finish.

Walk along the docks at any marina and there's sure to be several boats that catch the eye, standing resplendent above their neighbors. Glistening in the sun, the perfect brightwork draws your eye to the gracious sheer. You wish you could get your own varnish work to look that good. Well, you can — with a little effort and know-how.

What Is Varnish?

Varnish, simply put, is paint without the pigment, and it protects wood from sun, sea, wear, and tear. If it makes the wood look good in the process, that's a bonus. My first attempts at varnishing were poor to the point of embarrassment, but they did the job of protecting the underlying wood. With each application comes an opportunity to do better than last time; practice really does make perfect.

Varnish is a mix of resins, oils, and solvents (see " Choosing The Right Varnish "), although newer varnishes often have synthetic materials blended in to improve flow characteristics. Choose one type of varnish and stick with it. Don't dismiss a varnish too quickly just because you're not getting the finish you desire; it could be your technique or such other outside factors as temperature, high humidity, and dust.

Tools For The Job

The one essential tool is a decent brush. While modern varnishes are somewhat forgiving in terms of technique, they're very unforgiving of the wrong brush. Never use an inexpensive synthetic brush to apply varnish — the bristles will come out, and it's unlikely to have sufficient body to hold enough varnish. Many pro varnishers like to use high-quality badger-hair brushes; these have excellent flow characteristics and can produce spectacular results. However, I've become a big fan of foam brushes, and I know some pros who use them almost exclusively. They don't shed hairs to mar the finish, and they seem to hold just the right amount of varnish. Most beginners lay on varnish too thickly, and in warm weather, this leads to a condition known as "alligatoring," when wrinkles appear in the varnish and make the results look like alligator hide. Foam brushes tend to prevent this. Avoid inexpensive foam brushes because the shanks that fits into the dowel handles have a tendency to break. The biggest advantage of foam brushes is that you can just toss them at the end of the job. Pure bristle brushes, on the other hand, require meticulous care and should be cleaned before and after use, then wrapped in some aluminum foil to keep the bristles straight.

You'll also need plenty of clean, lint-free rags for wiping down the woodwork and performing other cleanup tasks. A vacuum cleaner is a great asset, and a lightweight model with a brush attachment is perfect for sucking up sanding dust.

Use 320-grit abrasive paper for light inter-coat sanding. Make sure the surface is dust free before applying the next coat.

You'll also need lots of abrasive paper. Cheap sandpaper is a waste of money because the grit falls off almost as soon as you look at it, and it wears out very quickly. I favor the gold, open-coat paper made by 3M. It's an aluminum oxide paper that cuts fast, lasts a long time, and comes in all grits. Buy 80 grit for sanding bare wood, 120 for sanding the initial thinned coats, and 320 grit for sanding between full-strength coats.

Tack rags are very valuable for picking up all those last bits that get missed by the vacuum cleaner and solvent wipe. Keep tack rags in a resealable bag when not in use to prevent them from drying out and getting dirty.

Preparation

One of the prerequisites for a perfect job is the correct attitude. It's easy to get overwhelmed by the amount of work that lies ahead of you. If you break the job into manageable pieces, it starts to seem less daunting. You might varnish the toerails one day, then move on to the handrails the next.

Working outdoors in the boatyard is often not the best place to do brightwork, especially if the guy next door is pressure washing his hull. If you can, remove parts from the boat that you can varnish under cover in a controlled environment, such as a garage or workshop. Hatch covers, washboards, and cockpit tables can all be removed and worked on indoors when the weather is less than stellar. Try to varnish on a warm day with little wind, and plan so you'll have few interruptions.

Read and understand the instructions on the can, which will provide important safety information and tell you which solvent to use. Don't use any old paint thinner that you find lying around; use only the solvent recommended by the manufacturer.

Never use varnish straight from the can. Decant the amount you'll use in about 15 minutes into a paper cup or other clean container, pouring it through a fine-mesh paint strainer.

A deep gloss finish is achieved by filling the pores of the wood, so the initial coats need to penetrate and seal the wood. The recommended method is to thin the first coat to a 50/50 ratio with thinner. Add thinner to your decanted varnish and stir very gently with a clean stick. Allow the varnish to rest for a few minutes to allow any bubbles to disperse. Dip your brush about a third of the way into the varnish, then tap it lightly on the inside of the container to knock off the excess before brushing onto the wood. Keep the brush moving, and don't overbrush the varnish, a mistake known as "worrying." Three or four stokes should be all that's needed before you move onto the next section. Make sure the wood is coated fully but not dripping wet; the extra solvent you added will ensure that it's absorbed into the wood. Leave it overnight. The next day, sand the surface lightly with 120 grit paper, then repeat the varnishing procedure, but this time, thin the varnish by 25 percent. Now it will be noticeably thicker, and less will absorb into the wood.

An increasing number of varnishers now use foam brushes and appear to achieve spectacular results.

Leave these two initial coats to sit at least 48 hours before laying on the first full-strength coat. This gives the solvents time to evaporate and the varnish a chance to harden. Although you can apply additional coats without sanding, I don't recommend it. Any imperfections will be magnified by each subsequent coat. Sanding knocks off any rough spots, smooths raised grain, and allows the third coat to go on without a hitch. Sand lightly with 120-grit paper. Don't rub too hard or you'll go right back to bare wood. If the varnish balls up into a gummy mess, it needs longer to harden.

After sanding, it's essential to remove all of the sanding residue, dust, and dirt. Use a vacuum cleaner with a brush attachment on the woodwork and adjacent areas to remove as much dirt as possible, then wipe down all woodwork with a rag lightly dampened with solvent. Turn the rag often to avoid spreading dirt from one area to the next. Decant some fresh varnish into a clean pot through a strainer, but before starting to apply the varnish, lightly wipe the surface with a tack rag to remove the last remaining traces of dirt. Wipe an area just ahead of where you'll be varnishing. For example, I'll wipe about three feet of toerail, then leave my tack rag at the point that I stopped wiping. Working toward the tack rag, it's easy for me to pick it up and give the next three feet a quick wipe as I make progress along the boat.

Brush Technique

Think of laying on the varnish rather than brushing it on. We're not painting a fence here — we're on a journey to a smooth, mirror-like gloss. Varnish should be applied with a slow, deliberate stoke. Grip the brush like a pen and draw it across the wood, laying down a uniform coat. If needed, you can use two or three extra sweeps of the brush to distribute the varnish. Finish by drawing the brush from the wet area to the dry along the length of the grain. Reload the brush and apply varnish to the next section of wood, "landing" the brush just into the end of the wet edge. Repeat the process until you reach the end of whatever you're varnishing. Occasionally sight along the work with your head almost touching the surface. If you spot any areas that you've missed, or you see runs, make a note of them for touch-up with the next coat. Don't try to fix things now, because varnish starts to skin up remarkably quickly — trying to touch up at this stage will only make things worse. Five or six full-strength coats is the minimum to provide UV and wear protection, though eight or nine is better for that deep, luxurious gloss.

Sanding And More Sanding

For the ultimate finish, you must sand between each coat. Sanding between coats improves the glossiness of the finish. If you omit the sanding, each coat gets progressively rougher in both look and feel. Sand between coats with 320-grit paper backed with a cork or proprietary sanding block for large flat surfaces, changing the paper as soon as it start to lose its cut or become clogged. After sanding, remember to dust, wipe with solvent, then go over with the tack rag before the next coat is applied.

Before varnishing, wipe down the surface with the solvent or thinners recommended by the manufacturer. Use a clean, lint-free rag and fold it often to avoid dragging dirt from one area to another.

All your hard work will be rewarded with gleaming brightwork, but to keep it in tip-top condition, touch up any areas that get damaged as soon as possible. Many owners keep a small jar of varnish and a disposable brush aboard for this purpose. This is one time when you can get away with just slapping a bit of varnish on; the idea is to prevent water from getting under the finish and lifting it off. You can always do a proper repair job later.

The greater threat to varnish comes from the sun's harmful UV rays, so consider making covers for large areas of brightwork, such as hatches. These will keep your brightwork looking great for many years and lessen the amount of time you spend recoating.

Short Answer

Yacht varnish is a protective coating used to seal and protect wood surfaces on boats.

To apply yacht varnish, start by sanding the wood surface with a fine-grit sandpaper.

Then, apply a thin coat of the varnish with a brush, working in long, even strokes.

Allow the varnish to dry for 24 hours before applying a second coat.

Finally, sand the surface with very fine sandpaper before buffing it with a soft cloth.

What is Yacht Varnish?

Yacht varnish is a specialized wood finish designed to protect outdoor wood surfaces from moisture and UV damage.

It typically consists of a blend of resins, oils, and solvents that provide a tough, yet flexible coating, which is ideal for protecting boat decks, outdoor furniture, and other wood surfaces that are exposed to the elements.

Yacht varnish also provides a glossy, attractive finish that enhances the beauty of the wood.

Unlike paint, yacht varnish does not completely cover the wood, allowing the natural grain of the wood to show through.

It is also relatively easy to apply and maintain, making it a popular choice for marine and outdoor wood surfaces.

Benefits of Yacht Varnish

When it comes to protecting outdoor wood surfaces, yacht varnish is an excellent choice.

Not only does it protect the wood from moisture and UV damage, but it also adds a beautiful shine and luster to the wood.

Yacht varnish is a long-lasting coating that can provide years of protection under the right conditions.

It is also easy to apply and can be used on a variety of wood surfaces, including boats, decks, and other outdoor wood surfaces.

When applied correctly, yacht varnish offers many benefits.

It forms a protective barrier against moisture and UV damage, preventing fading, cracking, warping, and other damage that can occur with prolonged exposure to the elements.

The coating also helps keep the wood from rotting, which can be an issue if the wood isn’t properly sealed.

Finally, the varnish adds a beautiful shine and luster to the wood, making it look like new.

Yacht varnish is also easy to apply and can be used on a variety of wood surfaces.

It is a great choice for any outdoor wood surface, including boats, decks, furniture, and more.

It is also relatively inexpensive and can be found at most home improvement stores.

With the right application, yacht varnish can provide years of protection and a beautiful finish to any outdoor wood surface.

Preparing the Wood Surface

Before applying yacht varnish, it is important to properly prepare the wood surface.

The surface should be thoroughly cleaned and dried, and any old varnish should be removed.

Sanding the wood will also help to ensure a smooth, even finish.

It is important to use the correct type of sandpaper for the project.

For instance, a medium-grit sandpaper is suitable for most wood surfaces, while a finer grit may be necessary for surfaces that require a more delicate finish.

Once the surface is prepared, it should be wiped down with a damp cloth to remove any dust or debris.

This will help ensure a successful application of yacht varnish.

Applying the Varnish

When it comes to applying yacht varnish, its important to understand the steps involved in the process.

First, the wood surface should be clean, dry, and sanded.

This ensures that the varnish will adhere properly and will provide maximum protection.

Next, apply a thin coat of varnish with a natural-bristle brush.

This helps to ensure even coverage and minimal brush strokes.

Allow the varnish to dry before applying a second coat.

Its important to allow the varnish to dry completely before applying any additional coats.

Sand lightly between coats to help ensure an even surface.

Additional coats should be applied as needed, but always be sure to allow the varnish to dry completely before exposing the surface to the elements.

With proper application, yacht varnish will protect your outdoor wood surfaces for years to come.

Allowing the Varnish to Dry

When it comes to yacht varnish, it is important to allow the varnish to dry completely before exposing the surface to the elements.

This will ensure that the varnish is properly bonded to the wood and will provide optimal protection from moisture and UV damage.

It is best to allow the varnish to dry for at least 24 hours before applying a second coat.

The drying time will also depend on the temperature and humidity of your environment, so it is important to allow for extra time if these conditions are not ideal.

Once the varnish is dry, it is recommended to lightly sand the surface before applying a second coat.

This will help to ensure that the varnish bonds properly and that the finish is even and smooth.

If additional coats are needed, the process should be repeated.

It is important to allow the varnish to dry completely between each coat, as this will ensure that the varnish fully bonds with the wood.

For best results, allow the varnish to dry for at least 48 hours before exposing the surface to the elements.

By allowing the yacht varnish to dry completely, you can be sure that the wood is properly protected and that the finish will last for years to come.

Sanding between Coats

Sanding between coats is an important step when applying yacht varnish.

After each coat of varnish is applied and has dried, the surface should be lightly sanded to remove any imperfections.

Sanding helps create a smooth, even finish and provides more effective protection against moisture and UV damage.

It also helps ensure that the next coat of varnish adheres properly to the surface.

When sanding between coats, use a fine-grit sandpaper (preferably around 320-400 grit) and sand in the direction of the wood grain.

This helps prevent scratches and other damage to the wood.

Be sure to only sand lightly, as sanding too aggressively can damage the wood and reduce the effectiveness of the varnish.

After sanding, use a clean cloth or brush to remove any dust or debris from the surface.

This will help ensure that the varnish adheres properly and provides the best possible protection.

Once the surface is clean, apply the next coat of varnish as normal.

With proper sanding between coats, yacht varnish will provide effective protection and lasting results.

Applying Additional Coats

Once you have applied the first coat of yacht varnish, it is important to apply additional coats for the best protection.

Depending on the specific product you are using, you may need to apply anywhere from two to seven coats.

It is important to allow the first coat to dry completely before applying any additional coats.

When applying additional coats, it is recommended to lightly sand the surface between each application.

This will help ensure a smooth, even finish and allow the varnish to adhere better.

After sanding, be sure to remove any dust or debris before applying the next coat.

When applying multiple coats of yacht varnish, it is important to use the same type of brush and same technique each time.

This will help ensure a consistent finish.

For example, if you used a natural-bristle brush when applying the first coat, it is recommended to use the same type of brush for subsequent coats.

Additionally, use long, even strokes when applying the varnish.

It is important to note that you should avoid applying too many coats of yacht varnish.

Too many coats can cause the varnish to become too thick and may make the surface appear uneven.

Generally, three to four coats should be more than enough.

Once you have finished applying the desired number of coats, allow the varnish to dry completely before exposing the surface to the elements.

With proper application and care, yacht varnish will help protect your outdoor wood surfaces for years to come.

Final Thoughts

Yacht varnish is a great way to protect your outdoor wood surfaces from moisture and UV damage.

Its important to apply yacht varnish correctly in order to get the best results.

Start by preparing the wood surface, then apply a thin coat with a natural-bristle brush.

Allow the varnish to dry before sanding and applying additional coats as needed.

With proper application, you can enjoy your outdoor wood surfaces for years to come.

Now that you know how to use yacht varnish, why not give it a try on your next project?.

It’s just expected that I would like the wooden parts of my boat to look great. I’m glad to have found this product from a marine spar varnish review. It works magically on exterior wooden parts that are above the waterline like railings and trims.

I like how flexible this varnish is as it has an oil-based formula. Thus, it can expand and contract as the weather changes. It can even endure the harshest weather. A marvelous clear finish will still be captured! I can say that it’s a perfect marine varnish for outdoor furniture.

I’ve also witnessed how durable the result is. This coating can resist salt, mildew, and UV rays. It’s the part that I appreciate the most. Aside from the beautiful gloss and the crystal clear finish, maximum protection is guaranteed. The surface is protected from water, chemicals, and sea spray.

It stands out among exterior varnishes as its durability is the same as the conventional wood finish. Its strength is even twice as much as the latter. The warm golden glow that it gives is simply stunning.

It takes two hours for every coating to dry, but it’s worth the wait. When durability means spending more time on the varnish, it’s not a problem then. Since I applied it on my boat, the wooden surfaces are firmer than before. I love how the odor is not too intense while I’m applying it.

• Perfect for exterior wooden parts that are above the waterline
• Flexible and durable oil-based formula
• Resistant to salt, mildew, and UV rays
• The finish protects the surface from water, chemicals, and sea spray.
• Gives a warm, golden glow to the wood

You may find this varnish well-rounded as it can be utilized in many applications. It can also be the most trusted marine wood finish. The formula is composed of alkyd resins, tung oil, and phenolic. There are UV filters, too to form superior protection.

With its components of the highest quality, you can expect the best from this product. The excellent flow of this varnish is absorbed by the wood, and that’s why the finish is akin to solid rock. So the durability of the finish can’t be denied. It establishes exceptional longevity.

Since it can give out a durable result, my boat’s wooden parts, including the floor, will maintain its extremely glossy finish. It can be completed in just a single day. From what you can expect in varnishing, there’s no shortcut if you want to achieve the optimal effect.

The finest ability of this varnish is also applicable for furniture set and some stuff in the household. There are many ways to apply it: rolling, brushing, spraying, and tipping.

When having it on a horizontal area, it’s best to use a brush. It can be a lot of work, but there’s a purpose behind it. This method will allow you to lessen the formation of bubbles. I feel so happy after laying out this varnish on the floor. It pays off the hard work.

It’s the best option for any type of interior and exterior wooden surfaces in your boat, kayak, canoe, and other water vessels. It can also be used on furniture, garage doors, tops, and more.

The classic varnish formula is just amazing. It is made up of premium tung oil and phenolic resins. UV blockers are also added to come up with a brilliant result that is transparent amber. It also oozes with a warm effect for both interior and exterior varnishes on any wooden surface.

Aside from the nice looks that it brings, it is also a durable marine varnish for wood. It’s due to its resistance to sunlight and being waterproof at the same time. The radiant result of this varnish is deemed to last. You can apply it with ease, as it can be done through a roller, brush, or spray gun.

There are two choices of this varnish: gloss and satin. The gloss varnish appears so clear and with depth. You should apply 4 to 6 coatings. The more layers, the better. I prefer using satin varnish on interior parts as it’s good at enhancing texture.

Applying this varnish once or twice a year is a part of my boat’s maintenance . Three applications are recommended per day. Recoating can follow in a matter of an hour. The coatings you have done in a day should be given 48 hours to dry up completely.

• Suitable for interior and exterior wooden parts
• A mixture of premium quality substances
• Has waterproof UV blockers for durability
• Gives off a radiant finish of two kinds: gloss or satin
• Can be applied by different tools
• The varnish is soaked in the wood on the first coating.
• Needs 48 hours for drying

This product may be commonly used for woodwork, furniture, cabinet, paneling accessories, and doors. But it is included in many marine spar varnish reviews. Do you want to know the reason why it can be a great varnish on wooden parts of your boat?

It’s a clear gloss formula that bears special oils. With these components, this varnish can expand and contract with the wooden surfaces. The changes in weather, temperature, and season won’t be a hindrance anymore.

The clear gloss finish won’t be prone to graying and fading due to the UV blockers. Once applied to the wood, it creates a protective barrier against moisture and rain. With the aforementioned characteristics, it is an undeniably essential part of any water vessel maintenance.

I use it for both the interior and exterior wooden sections of my boat. It’s like a custom as I do the application every year. I don’t need to look for a better product for I’m satisfied with this varnish.

I’m surprised that it dries quicker than what I expect from an oil-based formula. The result makes the wood a bit dark, but I’m not complaining. I do rather love the effects as it enhances the color and appearance.

• Used on many things (woodwork, furniture, cabinet, paneling accessories, doors, etc.)
• The formula contains special oils
• Can adapt to the changes in weather and temperature, blocks rain and moisture
• Gives a clear, glossy finish
• Has UV blockers so it’s prone to graying and fading
• Makes the wood appear a bit darker

It is recommended as a protective coating for exterior wooden surfaces because of its abilities. The layers of finish from this product are long-lasting, and I find its durability outstanding.

It’s spar urethane water-based as it can deflect water and is highly resistant to mold, mildew, scratches, and possible damage from UV rays and harsh weather. You may need to do some cleaning up to keep the gloss at its optimal appearance. Use soap and water to keep it neat.

Nonetheless, I also use it on the inside of my boat. I don’t want this area to be deprived of the amazing effects of this coating. It’s convenient and comfortable at the same time to apply it in the interiors as it has low odor. So I don’t get suffocated with some undesirable fumes.

When I went over the exterior wood finishes comparison, it dried quickly as it only needed thirty minutes. I love how easy it is to apply for its absolutely stunning effects. Just make sure you don’t do it when the temperature is over 90 degrees Fahrenheit.

Applying it when the temperature is high would make it dry before you achieve an even coat. A whitish tint will be the final result. I do re-coating after two hours, and it’s done four times as per the manufacturer’s recommendation. A quart of this product can cover 87 square feet.

• Long-lasting and durable
• Can deflect water and resistant to harmful factors
• Can be cleaned with soap and water
• Good for both exterior and interior areas
• Has a low odor
• Relatively dries quicker
• Three choices of finish: satin, gloss, semi-gloss
• Turns into a whitish tint when the temperature is over 90 degrees Fahrenheit

I must admit I like matte, but I won’t turn into this wood finish if it’s not giving my boat the striking effect. The satin sheen that it gives is so nice, and it gives a soft matte attractiveness.

This finish can also be proud of its durable outcome as it has UV protection for wood, teak , and other hardwoods. Aside from having it on my boat, you can see its marks in my house as I love wood pieces more than concrete. You can rely on it to protect the wooden surface from outdoor elements.

It’s a one-component matte finish that has tung oil and phenolic-modified alkyd resin. Imperfections in the wood are concealed when applied. I think it’s because of the minute porosity properties. Due to this factor, sanding is not necessary between coatings.

The matte finish has a rubbed look effect, which I like the most. I read on marine varnishes reviews that it’s challenging to apply this substance that is more liquid. When applying with a brush, you have to be quick and put it evenly.

Knowing some techniques would make steps a lot better. I used mineral spirits to thin it out. I added 25% of it for the first coating and just 10% for the second one. I find it dead flat on the first coating, but I’m amazed on the second try as it showcases the perfect matte finish.

• Gives satin sheen and a soft matte finish
• Durable with protection against UV rays
• Great for exterior use
• Conceals wood imperfections
• Sanding not necessary between coatings
• Humidity is fine for the first coating.
• The application should be made quickly

You just can’t underestimate old school, just like this varnish from Pettit. It’s still among the most favorite marine polyurethane varnishes, and it gives the same result for 55 years. I don’t know if it sounds funny, but patronizing this product has been handed from my grandfather to me. My boat teak as well as pieces of furniture benefit from its gloss finish.

What makes me and my family use it most of the time is its durable finish, just like how I keep using my boat teak all year round without looking worn out. It’s like an inch thick that seems to project a nice-looking 3D surface.

Its toughness is also tested on the mahogany door at home. This door is exposed to direct sunlight. It’s in its second year now, and I think I need to wait for another two before reapplying.

Thus, it is considered as a spar varnish to exterior door. The credit goes to the UV protectors which prolongs its life. It’s the ultimate shield from the harshest environment.

All these wonderful things happen because it is a water-based, marine grade polyurethane gloss varnish. It’s rich and obviously, of high quality. You can also use it on interiors too aside from brightwork exteriors. The clear and smooth finish reveals the natural beauty of the wood.

The texture of this varnish is like wet honey. When you use a new paintbrush for application, try to apply the varnish first on a spare surface. It should be done to avoid loose hair.

• Can be used for boats and other things
• Has a gloss, thick, durable 3D-looking finish with UV protectors
• Ultimate shield from the harshest environment
• In high quality, suitable for both interior and exterior use
• Clear and smooth finish to showcase the natural beauty of the wood
• Allows you to make the looks that you prefer
• Have to apply first on the spare surface to avoid loose hair from the new brush

I have built canoes and kayaks made of wood for many years. This varnish is what I ever wanted. It’s best among the ones that I tried. The solution went through proper curing as the system contains three kinds of epoxy. It’s available in satin and gloss finish.

When it comes to marine varnish comparison of easy application, this coating excels among the rest. It can be applied by spraying, so it doesn’t require much more effort than using a brush or roller. You will achieve a smooth satin or gloss finish without working so hard.

This varnish is formulated for marine and exterior surfaces that are made of wood. It doesn’t only look good, but it’s also tough enough to withstand sunlight and other outdoor elements.

One of its components is the ultraviolet light absorbers. Front doors exposed to sunlight can be well protected by this coating. The finish is also protected from water and salt air to remain stunning for a long time. It is VOC compliant with its high solids.

I’m grateful for this product as I can make striking kayaks and canoes. I receive a lot of compliments from my customers, and referrals come from time to time. Hence, it keeps my earnings at its peak.

• A convenient way to apply is by spraying.
• Available in satin or gloss finish
• Has the protection from water and salt air
• Hasultraviolet light absorbers to withstand sunlight
• The finish remains stunning for a long time.
• VOC compliant with high solids
• Fast-drying varnish

I like the effect of the varnish on the wooden parts of my boat. It doesn’t alter the original color as other products do. The red or orange result only pisses me off. I’m glad I chose this product as it leaves a color that is something around amber or brown.

If your color preference is the same as mine, this is the Epifanes marine varnish for you. I always achieve a flawless finish from this product. I think it’s because of its contents which are tung oil, phenolic, and alkyd resin. I’m in awe of its extremely glossy finish.

It’s a varnish that is not just for display but it guarantees durability as well. Its formula is fortified with UV filters. That’s why you can’t only use it on interior parts but with exterior too. Aside from being a marine grade lacquer, it is usable on furniture and other wooden stuff in your house.

The application of this varnish applies to new pieces of wood. It’s also useful for restoration. It’s great on both hardwood and softwood as it will still leave a deep clear finish that everyone is looking for. Thus, you can have it for maintenance or just a newly made water vessel.

The acceptable methods of applying this varnish are by spraying, brushing, tipping, and rolling. The texture is fairly thick but you can still end up with an even result. So you don’t need to questionthat its popularity as it has the highest quality for a traditional tung oil marine spar.

• Leaves a nice color of amber or brown
• Gives a flawless and glossy finish; ends up with even result
• Fortified with UV filters
• Can be used for restoration and new wood
• Can be applied in various methods
• In highest quality tung oil
• May require sanding for adhesion

This is the top-rated marine polyutherane that you can rely on. It reduces the things that I need to do when maintaining my boat in good condition. Once the brightwork is done, only minimal maintenance is necessary. It is one of the marine grade finishes that provide satin or hard gloss results.

The varnish solution is super flexible as it naturally expands and contracts despite weather changes. It remains in its superb look without yellowing, lifting, or cracking. The excellent adhesion adds up to its durability.

This varnish can effectively block harmful UV rays. Harmful factors like moisture, scratch, and abrasion can also be prevented from happening. Whether you apply it on the exterior or interior sections, the finish remains brilliant. You may also utilize it in enhancing the appearance of furniture.

Even though this varnish gives a beautiful result, handling and application are both a piece of cake. It’s in a resealable pour pack for convenience and no mess usage. This feature also makes it uncomplicated to store while you avoid wasting a single drop of the varnish.

This substance is low VOC, and it can be applied by spraying, brushing, or with a roller. I love how my nose is not bothered by any fume and how it dries quickly. So you have to make your movements nimble. It implies that you can finish fast as five coatings can be done in a day.

• Makes boat maintenance minimal
• Can have a satin or hard gloss finish
• Anti-UV, durable and not prone to damages
• Suitable for exterior and interior
• Convenient and ease of use; can be applied in various ways
• Dries quickly; no sanding is needed
• Need to make nimble movements as it dries quickly

The most important part to me is that the varnish creates a durable finish. I find this product trustworthy for protecting the wooden surface of my boat. Maximum UV blocking is included in its formula, and that’s what I need when summer comes as I often go out with my boat this season.

The finish is also water and salty air resistant. It’s also not prone to damage that can be caused by bad weather conditions. It gives the boat a nice appearance, and it keeps the beautiful surface as time goes by. So I feel secure that my boat can keep the shiny surface for a long time.

The clear satin finish is just awesome. It won’t only look good on the boat’s wood trim above the water, but also with outdoor wooden furniture, planters, lamp posts, interior window frames, and mills.

The durability is outstanding. It can preserve the good state of these things. I recommend using it on the front door, which receives a lot of sun rays. You will benefit a lot from this varnish if you live in a hot area.

A good bristle brush or a foam brush can be used for the application. The consistency is not similar to honey, so you can lay it out easily. It will be dry to the touch in a matter of four to six hours. Three or four coatings are needed. A light sanding can be done in between.

• Has maximum UV protection
• Resistant to water, salty air, and bad weather
• Can maintain the good appearance of the wooden surface
• Creates a clear satin finish
• Can be used on boats and household stuff
• Efficient and dries quickly
• Can be cleaned with ease
• The need for slight sanding

The other name for a marine varnish is spar varnish. It has a formula that is specially crafted for marine exposure. Tung oil, phenolic, and alkyd resin are the usual components present in it. It is deemed as an excellent varnish that forms a finishing suitable for the wooden surface.

It was made for the pole of wood found in sailing ships in the past. Changes are inevitable until it’s the scope of use includes all the wooden areas of the boat. It’s done as a part of maintenance and for beautification purposes nowadays.

The result from the marine varnish is sturdy. It can withstand bad weather conditions, water, and salty air. Its coverage is great on an unpainted wooden surface. People in every corner of the world would call it water-resistant exterior varnish.

Using a marine varnish, you are creating protection not only with your boat but also for furniture and projects with wooden materials. What’s under the covered deck can be in wooden form. So it means that it is exposed to different weather and harsh exterior elements.

To cite an example, UV rays are not too friendly towards the wood. Thus, chalking and cracking occur, and they destroy this material. So a marine varnish is an essential thing to your boat or other vessels. Doors displayed to the sun’s heat all the time can also be protected by the varnish.

When it comes to application, the general recommendation has three coatings. The first one should be thinned with 50% mineral spirits to give way to diffusion. The next step would need two full strength, and sanding may be required between coatings.

The classic varnish is extracted from a resin tree. The thicker one that is present these days is a combination of tung oil, alkyds, and phenolic resins. Furniture pieces were the ones that are receiving the gloss, but later on, boat masts started to take the coating too.

Masts bend with the wind, so varnish moves with it rather than cracking. Thus, a single part consists of a tung oil base, which is also called spar varnish. It is dissolved in solvents, and it’s being hardened right away after application. The first coating should be hardened first before the succeeding coating.

You have to give every coating adequate time as the solvent that’s under the layer will tend to evaporate.

Polyurethane

This oil-based varnish is composed of one part polyurethane. Chemicals that are similar to epoxy are in their content. Its usage is applied to covering clear epoxy resin. One way to make layers quicker is to apply epoxy on wood in just a matter of three or four coats of polyutherane with UV protection.

Polyutherane can either be water or oil-based. The advantage of water-based polyutherane is that you can easily clean the crystal clear finish. On the other hand, oil-based lasts longer, and it gives a bit of yellow color. It’s up to you if you prefer color enhancement.

Both of the bases should be hardened first before applying the next coat.

Exterior Varnish

It is formulated for outside utilization, and it specializes in providing UV protection. This varnish is microporous, which means that the wood can breathe. Therefore, mildew and mold don’t have the chance to assemble and rot the wood.

Yacht or Spar Varnish

It is mainly formulated for boats to counter the persistence of water. This solution is suitable for outside timber.

Acrylic Varnish

It is considered non-toxic and dries quickly. It’s quite flexible as it can be used on the inside and outside areas. Ultraviolet-light protection is its best feature. It can also be seen on other kinds of surfaces aside from wood.

The finish that acrylic varnish gives is so clear, but then it doesn’t penetrate the wood. There’s no complication when using it, so it’s user friendly. However, it would be difficult to spread the formula evenly.

Two-Part Varnish

Mixing is what is done with the two-part varnish. The base and the hardener are bought separately and then combined. Resistance to abrasion and durability are the highlights of its features.

Two-part varnish dries quickly as the moisture and air react to it. It shows that it lessens the weight of the job. The coating becomes very hard, too; thus, you can expect a long life from it. So you can go easy on maintenance.

The main reason for varnish application is to give your dear boat or any water vessel optimum protection. Investing in the top-tier marine varnish is a wise move. A boat is much more expensive than a can of varnish.

Choosing the ideal product, tool, equipment, and marine varnish can prolong the good condition of your boat. With marine varnish, you are given assurance that protection against damages is provided. It does an excellent job of safeguarding wooden surfaces.

A marine varnish can impede the accumulation of mildew and mold as well as water penetration and inevitable wear and tear. It does a wonderful job of enhancing the looks of your vessel. Your boat may even look like an expensive one.

The drawbacks of applying marine varnish exemplify the saying – ‘no pain, no gain’. But it doesn’t necessarily mean that you’ll be hurt. What it takes is patience, and it requires more time. You can’t get it done in just a snap of a finger.

The drawbacks would start with slow drying, so a lot of time is needed. Thus, dust built-up can also happen. Some boat owners will just be surprised about the incompatibility of the lacquer or water-based varnish. Issues may arise during stripping or repairing.

These are the things that you have to check when deciding what marine varnish to buy:

Most of the marine varnish is at a high price. So make sure that you pay for something worthwhile. You should have the initiative to check important information about the product. So you can avoid financial strains if you get the ideal product.

Cleaning Up with Ease

Even though you are careful, it can’t be avoided that there is some amount of varnish drops. With a formula that is easy to clean, you will find it effortless to eliminate the spill.

Easy Application

Applying the varnish can be challenging, especially for newbies on woodwork. If you are one of them, better use a product that is easy peasy for you to handle. Refer to the manufacturer’s recommendation of the best method of application.

The finish should serve you and your boat for a decent period. Who would want to go back and forth for repairs? Thus, it hinders you from spending money just to make corrections.

Time of Drying and Curing

Minimizing the drying time makes varnishing convenient for you. In this matter, you have to estimate the time that you will spend on your project. So you can manage your schedule.

Although marine varnish is consumable, you still need to be conscious of how you carefully take care of it. In this part, you have to be knowledgeable about the part by reading the label. Take note of precautions for everyone’s safety.

It should be away from the reach of children. Bear in mind that spar varnish is combustible. Don’t place it near open flames, hot surfaces, sparks, and of course, direct heat. Smoking beside it is hazardous to your lungs. It’s like giving yourself ailments as you breathe horrid substances.

When you apply varnish on your boat, you have to be in a well-ventilated area. You have to be outdoors. Protective gear is also necessary, such as gloves, a shield for the eyes and face, and a respirator.

Who makes the top-rated marine varnish?

TotalBoat marine varnish and spar varnish, RustOleum marine varnish or spar, Minwax spar urethane, Pettit varnish, System Three coating, McCloskey varnish, and Epifanes matte finish or Epiphanes marine varnish.

What is the difference between spar varnish and regular varnish?

Spar varnish is designed for outdoor use due to the consideration of different weather and temperature. Its formulation is different from a regular varnish. Humidity can cause the wood to expand and contract. When you use a typical varnish, it will easily crack and get damaged under this circumstance.

Aside from the protection that is provided by spar varnish, flexibility to UV rays is one of its features. So it extends the surface’s life, and it means durability. That’s why spar varnish is deemed to surpass the rigorous condition of marine life.

The difference between spar varnish and regular starts with the oil ratio. The former has more percentage of oil, which will soften the solution. It results in a more flexible finish. Meanwhile, the latter tends to crack when the wood expands or contracts.

Is marine varnish waterproof?

Yes, it is, but you have to take note of the components as each of them specifically works well with a certain kind of wood. For instance, some waterproofing methods are suitable for exterior or interior finish. Some are great for light or dark grained wood.

Make sure the components are compatible with your purpose of varnishing. If you wish to have an attractive and hand-rubbed finish, tung oil and linseed are the right components. It will be the first step that you need to take.

The second part is sealing the wood with lacquer and polyurethane. Of course, the final part is simultaneously waterproofing the wood. Use a stain-sealant combo for this process.

Is marine varnish better than polyurethane?

You can’t exactly say that varnish is better than polyurethane as each of them serves different purposes. It will depend on your purpose and preference too. The varnish turns into an amber or faint yellow shade. Its appearance is similar to the result of oil-based polyurethane.

The varnish is usually applied on water-exposed boats, outdoor decks, or deck chairs. What makes it suitable for these things are its water resistance ability and high solid content.

The formula of varnish has low toxicity, so it’s safe to utilize on exterior doors. The variant called marine varnish or spar offers flexibility and protection against UV rays. So most woodworkers are fond of it. They would apply it to softwoods that are known to flex under extreme conditions.

When it comes to varnish application, you must do it correctly. You also have to see to it that you give it enough time to completely dry. If you fail to do these things, the finish will likely crack, peel, or form some bubbles.

The wood can be susceptible to damages from the surroundings if you don’t do the necessary procedures properly. Several layers should be applied to achieve the optimal result. Give each layer six hours to dry so you can get the photo-finish result.

In the case of polyutherane, its texture can be compared to a liquid plastic. This attribute is based on its content, which can be resin or pure synthetic plastic. The milky appearance turns into a clear coat in just a single or two coatings.

Polyutherane is abrasion-proof, and it can correct a scratch. It is available in water or oil base and something in between called sheen. DIYers like it a lot as there are options like satin or glossy.

Since the content or base can be different, you should know the right designation of use. The water-based polyutherane gives off a revitalizing finish as it maintains the natural color of the wood. Perhaps, for its strength is the low toxicity level, you can clean its coating with soap and water.

The oil-based counterpart is usually seen on hardwood floors. It is capable of providing protection that is more robust than the water-based. So it’s not likely to just give up on UV damage and heat. You can rely on it so that it won’t crack.

The oil-based type is also heat tolerant. Its outcome enhances the wooden tone as it transforms into an amber tone.

To conclude, it can’t be claimed that varnish is better than polyutherane or the other way around. It all depends on the purpose of application or coating.

How long does marine spar varnish last?

The lifespan of marine spar varnish will depend on the environment. Exposure to direct sunlight can reduce its longevity. Rub spots because of hard service require fixing, which leads to the need to apply some coatings or layers.

Recoating should be done in cases of scaling. The affected area is sanded first to reveal the wood for recoating. A good six to eight coatings would remain to look awesome for 4 to 8 years.

You may have done every step properly, so coatings formed well on the wood. Maintenance has a big part too in prolonging the life of spar varnish. Keep it clean all the time.

Where can I buy it?

You don’t have to look high and low for marine varnish. You can get it from a home depot or any of your local hardware stores. You can also opt for online shops but make sure you access a legit website that provides a quality product.

There’s an array of brands both online and offline. When you check online, you can have more ideas about the product. So you can decide which one will work for you best.

What are some tips when applying marine varnish?

Applying outdoors is best done in the morning during the time that the dew has dried. Doing it in the late afternoon or the evening would lead to improper drying and loss of gloss.

Direct sunlight is not also good as it will make the varnish dry quickly. It’s not a recommended method. When you’re varnishing the interior sections, air ventilation is acceptable for drying.

It can’t be avoided that varnish may fall off at the wood edges due to the less film thickness. So what you need to do is to apply extra coatings. The first two coatings need to be thinned by 20% or 25%.

Sanding in between coats can be an extra job, but it is sometimes needed to achieve a flawless finish. It is a chance for you to correct mistakes like drips and runs. Make sure the previous coating is completely dried before you proceed to the next one.

When it comes to the brush that you need for marine varnish, you can try badger brushes. The most important thing that you have to pay attention to is the cleaning and maintenance of this tool. Always start the application with a damp, clean brush.

Think about the best marine varnish that can serve your purpose and application well. The formulation varies to suit the needs and preferences of users. So, it’s the buyer’s responsibility to check the components of a specific marine varnish they’re eyeing to buy. After you read this review, you’ll surely know what’s best for your boat or water vessel.

I am passionate about water sports and technical fields, so combining both makes me interested in making contents about boat accessories. With my partner, we went on many trips and sports games together, which led us to think about how we can spread our joys and passions to many people.

Topside Paint Test Kicks Off with a Look at Application and Gloss, Tips and Techniques

Practical sailor rates dozens of enamel, one-part urethane, and two-part urethane paints..

All that glitters isn’t gold, and as the price of professional topside makeovers continues to climb, many do-it-yourselfers are looking to other alternatives.

A gleaming paint job remains an icon of yacht-quality maintenance, and paint makers spin the transformative ability of what comes in their cans. The good news is that there’s still some truth in advertising. After a close look at the latest paint systems, Practical Sailor testers offer a report on just how user-friendly topside paints have become.

A few decades ago, an aircraft paint company executive decided to paint his boat with the same stuff used to coat aircraft that flew at 450 knots—the stuff that seemed immune to UV degradation and shed hydraulic fluid like water off a duck’s back. The results were more than impressive, and his experiment with a paint called Alumagrip led to a marine-coatings revolution and the birth of Awlgrip.

With the new brand came a new coating process that featured an epoxy primer and a sprayed linear-polyurethane topcoat. Today, Awlgrip has expanded its line to both polyester and acrylic-modified polyurethane top coats. The paint has become the gold standard among pros, but it’s occasionally used by amateurs.

Paint companies have responded to the demand for do-it-yourself (DIY) glossy finishes, and a plethora of single-part modified alkyd enamels, mono-urethanes, and two-part products line chandlery shelves.

In the same vein as our bottom paint and wood coatings tests, this topside paint evaluation begins with a report on application, handling, coverage, and initial gloss. After some field testing, we’ll rate each paint’s hardness, gloss retention, and long-term durability. Our last long-term look at these products was launched in the Feb. 15, 2002 issue and closed with a final report in the May 2006 issue.

What We Tested

We applied 29 topside paints from nine manufacturers to fiberglass panels. With such a large test field, we opted to divide the products by paint type. Of the test paints, seven are alkyd enamels; 12 are one-part urethanes; and eight are two-part linear polyurethane. We’ve classified two as “other” as they fit into none of the categories.

• Enamels: We found that choosing the right topside paint for the job at hand is based both on paint characteristics and applicator skill. At the easiest-to-apply end of the spectrum are traditional alkyd enamels, paints that are relatively soft, easy to sand, and almost creamy in brushability.

In the days of carvel-planked and clinker-built wooden boats, an annual coat of topside paint was part of the spring commissioning routine. The softer enamels delivered a season of shine, oxidizing a little over winter, and by spring, they were ready for a light-scuff sanding and a rejuvenating coat of alkyd enamel. Products like Pettit’s Z-Spar 100 and semi-gloss 101 and Interlux Premium Yacht Enamel were hard to keep on the shelf.

Today, there’s still an “enamel” demand, and products like Sherwin-Williams 1000, Kirby’s Hull and Deck enamel, and Z-Spar 1195 have been added to the fray. These paints excel in their ability to be easily applied. They are reduced with mineral spirit-based solvents and are soft enough for easy sanding between coats. However, the long-term gloss retention and adhesion of enamel is not as good as that of the higher-tech paints that have cornered the market.

• One-parts: In the middle range of topside paint technology are one-part urethane modified enamels. These are harder, glossier, and tougher coatings than alkyd enamels. They exhibit traits more akin to two-part systems, yet handle with almost as much ease as a traditional enamel. They are faster-drying, quicker-to-skin paints, and must be carefully thinned with specific reducers to retain good flow characteristics. A major benefit of these paints is their forgiveness on vertical surfaces where “hangs and sags” are just waiting to happen. Single-part urethane enamels offer multi-year shine, and on a couple of applications we have been field testing, the paint has weathered four years as a nonskid surface in a cockpit sole (Interlux Brightside).

• Two-parts: At the high end of the topside paint spectrum—in cost, durability, and gloss—are the two-part linear polyurethane (LPU) products that use an isocyanate catalyst to cure the paint. More a plastic resin than an old-fashion enamel, these “wonder coatings” typically afford a wet look that packs automotive showroom brilliance. The downside of this reflective quality is the need for smooth, even, dust-free application, and the extra effort associated with surface preparation.

All of the two-part products we tested produced superior results but also proved to be more difficult to handle than one-part products. One factor common to all of the two-part paints is the detailed prep work required, but testers found that it does pay off in the long run.

What We Found

• Enamels: Don’t sideline traditional alkyd enamels. They are easy to handle, require less exacting preparation, and are a pure pleasure to brush on. When used in low-abrasion situations where modest gloss is an asset, they can prove to be just the right paint.

Pettit’s Z-Spar No. 1195 Grand Banks Beige stole the show with its smooth, even flow and Excellent coverage. Other oil-based alkyds in the Z-Spar line (Nos. 99 and 100) featured the same remarkable handling quality that makes it a favorite among carvel and clinker-built wooden boat owners.

Both Kirby’s Hull and Deck Enamel gloss white and semi-gloss proved easy to handle and developed a smooth, even skin. The only disappointment was the streaky nature of its medium-gray enamel. Even after re-stirring, it required three coats to develop a smooth hue. The difference highlights the fact that even though one manufacturer makes multiple colors of paint, one color may not have the same gloss or application qualities as another color.

Sherwin-Williams’ Seaguard 1000 was another smooth-flowing, user-friendly, oil-based alkyd enamel. It spread evenly on vertical surfaces and was reluctant to hang or sag.

Bottom Line: Most of the enamels we tested performed well, comparatively. Our top picks so far for application and initial gloss are the Z-Spar Solid Coat No. 99 and Marine Enamel No. 1195.

• Single-part urethane enamels: By far, DIY topside paint technology has grown the most in the one-part urethane modified enamels sector, a best-of-both-worlds formulation that boasts of shine and longevity. Almost as user-friendly as an alkyd enamel and with almost as much gloss as the two-part paints, these hybrids certainly live up to expectations.

In a near photo finish in our application testing, Interlux’s Toplac and Epifanes’ Mono-urethane crossed the line in a dead heat with Insignia’s Resilience rounding out the winners’ circle. (Resilience is branded as a “for pro application-only paint.”) Snapping at their heels were Interlux Brightside, Pettit Easypoxy, and West Marine’s SeaGloss Pro. Two of the most popular colors on the nautical pallet have been Interlux’s Kingston Gray and Hatteras Off White.

Bottom Line: This was a close race, but the very slight edge for application goes to Interlux’s Toplac.

• Two-part paints: When it comes to surface toughness, bright gloss, and maximum longevity, two-part paints stand alone. Paint in name only, these acrylic and polyester modified-urethane resins have the ability to suspend pigment in a flat, highly reflective skin. The trick lies in applying the coating evenly and just thick enough for it to flow, making brush strokes or orange peel disappear.

As with all forms of juggling, a minor slip can spell major problems. Consequently for DIY interest, we looked carefully for paints that behaved well when rolled and brushed. Once again, Interlux and Epifanes crossed the line in a dead heat: Interlux’s Perfection and Epifanes’ Polyurethane products flowed smoothly over horizontal and vertical surfaces and resisted the tendency to hang or sag.

Fabula Inc.’s Signature Finish, which comes with brushes, rollers, tape, mixing graduates, stirrers, and detailed instructions also hit the mark. Sherwin-Williams’s vivid red two-part was the smoothest flowing red of the three we tested. Insignia’s Brilliance, like Awlgrip is a “pro only” recommended product, and once the right amount of brushing reducer was added to cope with the warm weather, these products also ranked as standouts.

The volatility of the solvents in all these two-part system leaves the user with less time to muck around, and maintaining a wet edge is essential to the “cutting in” process. Each manufacturer provides a “slow” brushing reducer that has to be carefully used. Too much causes excess flow—and the drama mentioned earlier of hangs and sags. In short, two-part paints typically provide the best gloss and toughest, longest-lasting finish, but they are the hardest to handle.

Bottom Line: The Awlgrip, Epifanes, and Interlux two-parts were the only products to earn across-the-board Excellent ratings.

• Other: As soon as we popped the lid on the first can of CrystaLac Crab Coat, we noticed change in the air. Absent was the aroma of oil or the volatile solvent jolt of urethane-based chemistry. In fact, the smell was imperceptible, and that made this paint especially appealing for those working inside a shop or below deck.

Crab Coat is not a water-based paint, but it is hydrophilic enough to allow water-only cleanup. It handles more like a blend between thick, creamy enamel and a water-based Latex. However, this paint is meant for exterior marine use. Time and our test panels will spell out how it weathers the environmental onslaught. It brushed on smoothly, but its Mystic Green color presented a somewhat streaky appearance.

Bottom Line: Though not as glossy as the current crop of urethanes, the Crab Coat produces a very appealing semi-gloss finish.

Topside and deck painting are labor-intensive undertakings that can rejuvenate an aging vessel as well as protect the substrate that lies beneath. Those enamored by the finish of the dark-blue Hinckley and Morris fleets have a tall order to meet.

Those willing to stay with white or a light color who are ready to invest equal amounts of time, patience, and skill, can parlay the cost of materials into a durable and attractive finish.

To say that the average roll-and-tip finish is just as good as a pro-sprayed finish would evoke too much of the Pinocchio factor. The results attainable by the average applicator can be quite good, but to hit the bull’s eye takes a steady hand, or the willingness to follow an autobody shop approach one of the paint manufacturers recommends.

One paint maker, Signature Finish, offers three sets of instructions, allowing DIYers to choose the level that suits them. Level 1 is straightforward: Apply three coats of their two-part paint (no primer), scuff sand between coats, and accept the last coat as the done deal. A Level 2 finish involves buffing with 3M Super Duty rubbing compound, and for those with more vigor and higher standards, there’s an exacting Level 3: Apply three or more coats, and once it’s dry (three to five days), wetsand it down to 1,200 or 2,000 grit followed up with the machine-buffing process. The workable acrylic LPU paint is highly buffable, and the result is a smooth, glossy surface, but care must be taken not to remove too much material.

Before committing to a big project, do a bit of testing of your own. A good test is to paint a pair of dinghy oars with good-quality enamel, then paint the inside of the dinghy with a one-part urethane, and finally flip it over, and go through a full prep-and-prime process that leads up to a roll-and-tip application of a two-part LPU paint. From this experience, you’ll have developed important painting skills and better understand the task that lays ahead.

All of the products we tested ranked at least acceptable in handlability, and many excelled. Only time will answer questions about durability and gloss retention.

Regardless of the paint you choose, be sure to review all of the manufacturer’s printed and online technical information, follow all safety procedures, and keep in mind that when it comes to painting, success is in the eye of the paint-brush holder.
