What’s the Best Varnish for Your Yacht?

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.

Clear Yacht Varnish. A clear yacht varnish does what it says on the tin: it will create a transparent, glossy finish that does not alter the colour of the wood it is applied to.
Matt Yacht Varnish. Using a matt coloured yacht varnish will result in a dull, non-shiny finish that does not reflect light. This can be ideal for hiding flaws or imperfections in wood.
Yacht Varnish Satin. A satin varnish falls between clear and matt. This type of finish will create a pearl-like sheen, without being overly shiny or reflective.

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.

How long does it take for yacht varnish to dry? Yacht varnish generally takes 4 – 6 hours to dry, although you should check the instructions for the specific product you’re using. You’ll probably want to do two or three coats of varnish, leaving sufficient drying time in between coats.
Is yacht varnish good for decking? This depends on the product you choose. Some yacht varnish is suitable for decking, while others are not because they do not have an anti-slip formula.
Is yacht varnish good for floors? Yacht varnish should not be used as an indoor floor varnish. It is difficult to dry indoors, and contains chemicals that can be toxic if it is not used correctly.
Is yacht varnish safe for animals? 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.

The Best Marine Varnish: Exterior Wood Finish Tests

Two-part varnishes leading in durability as long-term test reaches 24-month mark..

Like spotting land after a long passage, were glad to say that the end of our long-term exterior wood finishes test is finally on the horizon. Time, weather, and Southwest Floridas unrelenting sunshine have clearly taken their toll on the test panels over the last 24 months, and as the evaluation moves into its third year, only 19 of the original 54 test products will continue on in our survival-of-the fittest finish matchup. Given that most wood coatings are rarely expected to last longer than two years in the marine environment-particularly in super-sunny locales-its no surprise that we’ve seen more significant changes in the coatings in the last six months than we had in previous checkups.

Our search for the ideal wood finish-relatively easy to apply, easy to maintain, lasts multiple seasons, and is affordable-began in 2007 when we took a look at the different types of exterior wood finishes on the market, their pros and cons, and how easy they were to apply ( one-part varnishes , August 2007; varnish alternatives , October 2007; two-part varnishes , December 2007; teak oils and stains , April 2008). Launched in 2008, the long-term panel test aimed to determine which type of coating offers the best and longest protection and which products stand out among their peers.

We hope the comparison enables readers to decide which finish best matches their own taste, potential labor investment, and wood protection needs.

We’ve rated the test products every six months and reported on the coatings durability in the May 2009 issue ( six-month checkup ), December 2009 issue ( 12 months ), and January 2011 ( 18 months ) issues. Here, we offer the two-year report on the survivors.

How We’re Testing the Marine Varnishes

Testers applied dozens of exterior wood finishes (22 one-part varnishes, six two-part varnishes, 18 synthetics and satins/varnish alternatives, and eight teak oils and sealers) to small panels of bare solid teak. Each was assigned a number for blind judging and was applied per manufacturers instructions. If makers gave a range for the number of coats to apply, testers went with the minimum.

Initial testing rated each products ease of application and original gloss and reflective qualities. In the summer of 2008, the test panels were mounted on a wooden rack (aka: The Rack), which was set up in an unobstructed area on the roof of the PS workshop in Sarasota, Fla., to ensure that all panels received the same amount of weather exposure. The top part of each panel was covered to create a control area that testers used for comparison over time. Every six months, we disassembled The Rack and rated the panels on how well their coating integrity, gloss, and color had fared over time with constant exposure to the elements.

The test was designed as an endurance test, a fight to the finish, so we have not done any maintenance coats or touch-ups to the test panels. These products can be expected to have much longer lifespans if they are regularly maintained.

How We’re Rating the Marine Varnishes

Testers rate each panel on three long-term performance criteria: coating integrity, gloss retention, and color retention. Excellent and Good coating integrity ratings mean that no maintenance is needed; a Fair indicates that its time for a maintenance coat; Poor means the fat lady has sung, and the coating would need to be removed and re-applied. Excellent ratings are given only to those with an uncompromised coating. This time, panels with Poor and Fair- coating integrity were pulled from the test.

Color and gloss retention ratings are relative to the panels original finish. Initial gloss and ease of application are relative to the field within each coating category; these were assigned immediately after the panels were coated.

It was tougher to pick Recommended coatings at the two-year mark, as most wood finishes aren’t intended to go that long without maintenance. One-part varnishes that earned PSs recommendation this go-round were rated Fair for coating integrity (none rated better than Fair ) and had no Poor ratings. Recommended two-part systems rated Good or better for coating integrity with no Poor ratings. No varnish alternatives or teak oils/sealers were recommended at two years.

VALUE GUIDE: Varnish Alternatives

What we found.

What a difference a season makes! With the exception of a few two-part products, the test coatings had lost their sparkle at the two-year mark. Ratings slipped across the board. The UV abuse had obviously taken its toll, sucking the life out of most of the coatings, particularly the clear finishes.

Those clinging to life with Fair coating integrity are still protecting the wood, but they’ve lost their looks. In the real world, all of the one-part varnish and varnish alternative test panels would be due for a maintenance coat, and some-like HMG K Type Varnish, West Marine WoodPro Plus (rebranded Epifanes Rapidclear), and Ace Spar Varnish-would be overdue.

The biggest overall decline was within the one-part varnish test group: Not a single one rated better than Fair for coating integrity or gloss retention, and nearly half of the test field was retired after this rating round. Just six months before, eight of the 19 products rated Good for coating integrity and six rated Good for gloss retention. In 12 months, seven dropped from an Excellent coating integrity to a Fair.

The one-part varnishes offering the most protection after two years are Detco Crystal, Le Tonkinois Vernis, and Pettits Z-Spar Captains 2067. However, their extended protection comes with tradeoffs: Detco rated only Fair for application, Le Tonks gloss started to slip after one year, and Pettits 2067 started losing its original color after 12 months.

One hardware store varnish has surprisingly held its own over the long haul: Minwax Helmsman Spar Urethane. At half the cost of the Recommended one-part varnishes, Minwax slacked in the color retention department, but it has proven its multi-season durability.

Four of the nine varnish alternatives have been voted off The Rack after two years, and none performed well enough to earn our recommendation for two-year wood protection.

The Cetol products are still at the head of the pack, albeit a somewhat mangy-looking pack. The cloudy, opaque look of the Cetol Marine and Marine Light products may not appeal to everyone, but the fact they’ve maintained their color for more than a year is a good example that higher-solids finishes tend to offer better UV protection.

The Cetol Natural (with gloss) test panel fell from a Good coating integrity six months ago to being dropped from testing. Its performance mirrors what we’ve seen in the field: Give it a little loving once a year with a scrubby pad and a fresh coat, and it’ll last the long haul.

Its taken two years, but the two-part varnishes are finally starting to show their age. Surprisingly, the first products to be dropped from this group are two that performed well in past PS tests: Bristol Finish and Honey Teak. This is likely because the life of a wood finish in Florida is always going to be shorter than in our past test locales in New England.

The other two-parts are still holding up well, with Interlux Perfection and Nautiking Nautithane offering uncompromised protection and better-than-expected gloss after 24 months. Perfection has been reformulated since the test began and is now sold as Perfection Plus.

The temporarily discontinued (since 2009) Smiths Five Year Clear has also proven to be a top-notch finish, but its not available at this time.

While HMG Acrythane XSC didn’t earn our Recommendation this time, it was a top 18-month finish, it still looks good, and it costs less than the Nautithane.

Conclusions About Exterior Varnishes

After two years of testing, we’ve come to accept that perhaps there’s no Holy Grail of exterior wood finishes. It would appear, unfortunately, that we can’t have it all: easy to apply, easy to maintain, long-lasting protection, and a budget-friendly price tag. The reality is that, like much in life, wood protection is all about compromise and balancing your needs with your wants.

There’s no one-size-fits-all solution, and the boat owner who finds gratification in the wet, glossy look of a two-part varnish borne of painstaking preparation and careful application will weigh our test data much differently than the one who regards brightwork maintenance as a masochistic endeavor. For the latter, we recommend seeking out a varnish alternative (easy to apply, easy to maintain) that suits your tastes. With modest maintenance, the Cetol products with gloss overcoats have proven to be the most durable.

For areas where slippery-when-wet coatings wont do, Cetol Natural (without gloss overcoat) or our top-pick teak oil, Star brites Tropical Teak Sealer (classic teak) should be considered. The Star brite will need to be reapplied every three or four months.

If you’re looking for a harder, more abrasion-resistant finish that’ll make it past the year mark, check out the top one-part varnishes like Detco Crystal or Pettits Z-Spar Captains 2067. Boat owners in sailing areas that see less sunshine than our Florida test site should also consider Pettits Flagship 2015 or Captains 1015. One-part varnishes require a little more work upfront and quick attention when they are scratched or dinged, but they also offer a more traditional, high-gloss look. The one-part varnishes in our test slipped dramatically after a year and half, so we suggest an annual maintenance coat, whether they look like they need it or not.

As this test has shown, when it comes to long-lasting protection and gloss, two-part varnishes just can’t be beat. They may be a pain to apply-and should you let the coating fail, you had better invest in a heat gun-but their durability is unmatched.

The top two-part after two years of testing was Interlux Perfection. Because we’ve not yet tested the reformulated Perfection, the top pick honors go to Nautikings Nautithane. While its price tag ($120 per quart kit) is a bit hard for most of us to swallow, Nautithane earned across-the-board Good ratings after two years.

The Best Marine Varnish: Exterior Wood Finish Tests

Practical Sailor often supplements panel testing with product challenges aboard our test boats to see whether top products still earn their keep in the real world and to try out new products. Two such evaluations are our exterior wood finish tests.

In the January 2011 issue, we introduced a head-to-head matchup of varnish alternatives—market-newcomer PolyWhey from Vermont Natural Coatings versus perennial favorite Interlux’s Sikkens Cetol Natural Teak—that had been applied to our Cape Dory 25 test boat. For that test, we’ve just let nature run its course: no band-aid touchups, no maintenance coats, no freshwater rinses, no TLC at all.

Comparatively, we’ve been testing Cetol Natural aboard our Chesapeake Bay-based Union 36 test boat, where it was laid on with the Cetol gloss overcoat in 2008; in this evaluation, testers have applied annual maintenance coats and given the coating regular TLC. Here’s the latest on both of these tests:

PolyWhey vs. Cetol Death Match

In the fall of 2010, testers applied three coats of Caspian Clear PolyWhey to the coamings and companionway trim on the Cape Dory, which is sailed several times a week and lives on a mooring in Sarasota Bay, Fla. We also applied Cetol Natural to the boat’s toerail, and previously had applied it to the tiller and forward hatch trim.

PolyWhey is a unique wood finish that uses whey protein, a by-product of the cheesemaking process, as a binder. It’s touted as a more eco-friendly and more sustainable coating than petroleum-based polyurethanes, which can have up to 75 percent more volatile organic compounds (VOCs).

Consistently among the top varnish alternatives in PS’s tests, Cetol Natural is not as muddy-looking as its predecessors, Cetol Marine Light and Cetol Marine—like the Caspian Clear, it allows the wood’s natural grain to show and has a low gloss.

As far as application, both the Cetol and PolyWhey are quick and easy to apply, with much shorter recoat times than hard varnishes and less (or no) sanding between coats. The main difference that we found in these two finishes was with durability.

The PolyWhey turned out to be a much softer coating than the Cetol. It held up for about two months, but after three months, it was in need of a recoat, and at six months, it needed a total takedown—and Cetol had emerged as the death-match victor.

The PolyWhey on the coaming was the first to go: Where crew backs often lean against the wood, the finish was all but gone after four months. The PolyWhey on the companionway slides held on for about that long, but by six months, they were ready for a do-over as well.

The Cetol on the toerail was in need of a few touchups after six months, mostly in areas where fenders and docklines came in contact with it. But the tiller and hatch trim were still fairly well-protected almost a year after application. Although we’d recommend a maintenance coat at this point, testers plan to see how many more months we can eek out of the coating before we reach the point of no return.

Bottom line : We applaud VNC’s efforts to offer a “green” wood finish—and their creative recycling of dairy industry “trash”—but we can’t recommend it over Cetol for an exterior coating in the marine environment.

Cetol with Overcoat

Testers applied three coats of Cetol Natural with Cetol Marine Gloss overcoat to the Union in March 2008. Once a year, we scuff it up with a 3M pad, give it a freshwater rinse, and brush on a maintenance coat.

Compared to a clear, glossy varnish, it looks decent and the maintenance regimen is more realistic for our tastes and available time. However, one downside to softer, varnish alternative coatings—even those with an overcoat—is that they don’t stand up as well as hard finishes to dings and abrasion. Example: The Union’s toerail has one place in need of touching-up where a fender line wore away the finish. (See photo above.)

Bottom line : The Cetol Natural with overcoat has held up very well. While applying the topcoat may mean added effort, both our panel tests and test-boat evaluations have shown that the coating will last much longer and need fewer bandaids if the soft Cetol is protected with the semi-hard topcoat.

Teak oils and other naturally based finishes like PolyWhey, need maintenance coats every few months. Their chemical cousins, however, like Cetol, have proven they can offer good protection with only annual nurturing and the occasional touchup.

Table of Contents

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?.

James Frami

At the age of 15, he and four other friends from his neighborhood constructed their first boat. He has been sailing for almost 30 years and has a wealth of knowledge that he wants to share with others.

Choosing The Right Varnish

Don't know a resin from a polyurethane? Read on to learn how to decipher that can.

This small boat is finished with Awlwood giving a crystal clear surface that shows off hte wood grain.

There are lots of different makes of varnish available, and you'd think that you could just walk into your nearest store and pick almost any can, right? Not so fast! There's more to choosing the right varnish than it might appear — choose the wrong sort and you could be left with an expensive mess.

Basically, there are three kinds of varnish: Oil based, usually made with tung oil as one of the main ingredients; polyurethanes, which generally have a synthetic-oil base; and two-part varnishes, which, as the name implies, is a resin base to which a hardener, or catalyst is added prior to application. Unless you're starting off from bare wood, the most sensible way is to use the same finish that was applied last time. The varnish will be compatible with what's on the boat already, and the color will be consistent. When varnishing bare wood, almost any varnish can be used, but read the instructions on the can carefully before starting.

Tung-Oil Varnishes

Old-time varnishes were boiled down from tree resin. Older-style varnishes tend to be thicker and may be made from a combination of tung oil, phenolic resins, and alkyds. Most of these varnishes were developed for furniture and only later used for boat masts. Given that a mast flexes in the wind, the varnish needs to move with it rather than crack. This gave rise to single-part, tung-oil-based varnish often referred to as "spar" varnish. With these, the varnish is dissolved in solvents, so it begins to harden as soon as it's applied. You can apply a second coat of tung-oil varnish before the first layer is totally hardened because the solvents will keep evaporating out of the underlying varnish layer. Jim Seidel, who retired as marketing manager of Interlux, says, "You need to be careful when applying tung-oil varnish on horizontal surfaces as you can lay it on too heavily and it feels dry, but depending on the thickness of the coating and temperature you're working in, it may trap solvent and can lead to alligatoring." These varnishes tend to give a slight yellow cast to the wood.

Polyurethanes

Oil-based one-part polyurethanes are made using chemicals similar to epoxy and can be used to cover clear epoxy resin. In fact, one way to build up layers fast is to coat the wood with epoxy and finish with three or four coats of high-UV polyurethane. Polyurethanes can be oil- or water-based. Oil-based polyurethanes tend to be harder, and last slightly longer, but they can also crack. When applying oil-based polyurethanes, you need to let one layer harden completely, then sand it lightly, before applying a second coat. Oil-based polyurethanes tend to give a slight yellow color to the wood.

Water-based polyurethanes are easier to clean up, but they're slightly softer and don't last quite as long as oil-based. Again the varnish needs to harden before applying a second coat. Water-based varnishes can be almost totally clear.

Two-Part Varnishes

Two-part varnishes need to be mixed before they're used. In most cases, the base and the hardener are in separate cans, and you simply pour the contents of one can into the other and stir well. The advantage of two-part polyurethane varnishes is that they last longer and are far more abrasion resistant. It is important to note that due to the very hard nature of the coating, a two-part varnish can't be applied over a one-part varnish, as they're incompatible with each other. The problem with two-part varnishes is that they only have several hours in which they stay liquid. (The "pot life" that the varnish stays useable can be from several hours up to two days.) Once the varnish is spread out on the job, it will begin to harden as air and moisture in the air act on it. These varnishes tend to be clear and need to be thoroughly dry before a second coat is applied. Steve Schultz, formerly with Interlux and now with EMC Quantum, says, "Two-part varnishes are a better choice because they last longer and reduce the labor required. In turn, this reduces the overall cost of varnish maintenance."

Two-part varnishes contain isocyanates, and while many are meant to be applied by a professional (with safety precautions) they can be brushed on provided the user wears a respirator. Isocyanates become a problem when they're sprayed because the fine particle size can affect the user's lungs. Brushing them, provided the user observes standard safety precautions (gloves, eye protection, and respirator), is preferable.

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.

How to use Yacht Varnish

Before you start.

Make sure your wood is dry before you begin. Choose a day that’s reasonably warm (above 10°c) and dry.

This varnish isn’t suitable for decking though.

How to prepare wood for varnishing

You will need to remove old stain or varnish by sanding it down. Use 120 grit sandpaper and sand away the old finish.
Wipe down the surface with white spirit and a cloth to remove the leftover dust.

If your wood is brand new, you will need to sand it to remove loose wood and clean with white spirit.

Application

Thoroughly stir your varnish to make sure it’s smooth and there’s no lumpy bits.
Test it on a small patch of your door. It’s clear varnish but it may still darken the natural colour of your wood so make sure you’re happy with it.
If you are, start painting with a brush. Go in the direction of the grain and for best results, apply two or three coats. Wait eight hours between each coat.
Before you apply your last coat, lightly sand the surface and use white spirit to remove the excess dust. This will give you a nice smooth finish. Your last coat will be dry in four hours.

Once your varnish is dry, you’ll be able to clean your door as normal. Keep on top of the dirt and grime for a friendly welcome to your home.

You can clean your brushes with white spirit or brush cleaner.

It’s easy to repair your varnish if sections of it become damaged. Simply use some sandpaper to sand down and smooth out the damaged part and then add a couple of coats so it’s good as new again.

Boat Varnish 101

By George Sass, Jr.
Updated: November 25, 2009

ytgnov25enewsvarn525.jpg

When is it time to revarnish your exterior brightwork? I used to apply at least three coats on the trim of my 1962 Pacemaker every spring. In addition, I would make sure two coats were applied in the fall to protect the finish from the long winter ahead. Applying one coat of varnish, especially after the prep and the taping involved, is a waste of time. Make sure you apply at least two coats.

Pay close attention to any deterioration around seams and edges, or where water has been able to intrude. Do not let these spread. I had an issue around my stanchion bases, until I removed these and rebedded the bases, fighting off the moisture. If you see light areas or dead varnish, you’ll need to repair and build these back up before finish coats are applied to the entire surface.

To make this repair, the first thing you want to do is to remove the old varnish. I continue to swear by the Red Devil 1-inch scrapers. I’ve had several for decades and they work well for small tasks like seam repair. Just make sure you keep the blade sharp. Also, be careful not to mark the wood or dig too deep with the scraper.

While repairing seams or small blemishes, try to keep the area you are working with small. The object is to fair in the damaged spot with the good varnish. By keeping this area relatively small, the fairing job is much easier.

A common mistake made with this process is not having the patience to fair bare wood after you remove the old varnish. Believe me I’ve kicked myself on more than one occasion for not taking the proper steps. You want to start with 120 grit paper, then go up to a 150-sheet, and end with a 220-grit once the wood is smooth. If this is not done properly, you can be left with scratches from the scraper and sanding.

The mahogany transom on my Pacemaker would often lift at the scarf joints. In a few areas, water would penetrate and darken the joints. If your wood has a few of these dark spots, do yourself a favor, and take the time to bleach these out with a teak care product and soft pad. Make sure the area is completely dry before you varnish, or the entire process will be for naught.

After the spot is stripped, you may need to stain the area in order to blend it with the rest of the brightwork. This is more common, in my opinion, with mahogany finishes. With teak, I’ve seen people go nuts trying to “match” the finish to a uniformed look. My friend Bruce Livingston, who built Little Harbor custom sailboats, and worked with me at Grand Banks, and is now at Vicem (and they know wood) used to say the object is to “blend.” I agree. But if you’re set on staining, go with a product from the same company as your varnish.

And make doubly sure that you stir until your hand falls off. I’ve ruined my work by applying a stain, but all the pigment was stuck at the bottom of the can. So all I did was smear colorless oil. Great move, Sass.

Then it’s time to start laying some varnish on the prepped spots. What type of brush? To build coats, I go with foam brushes at this point. I can toss them after each application and save my finish brushes for the larger applications.

When applying varnish to bare wood, make sure you thin the first coat. I thin the first coat by 50 percent. Since this dries in a few hours, you can go back on the same day with a second coat, thinned by 25 percent. Do not sand after these coats.

Then, you can build the spots back with varnish and minimal thinner. Apply one coat a day and sand with a 220 grit paper, until the areas are built up to the same thickness as the surrounding varnish. Then it’s time to varnish the entire area to get the golden finish.

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...

best-boat-varnish-81hp8vGUltL._AC_SL1500_

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

• More expensive than Epifanes • Not as impact or abrasion-resistant as some other offerings • Not as much UV protection as some other offerings

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

Hempel’s 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.

Teak alternatives: How to make your decks look as good as the real thing

However, according to a recent report by the Environment Investigation Agency, there are grave questions over the sustainability and sourcing…

If you need to save the varnish overnight, take a look at this top tip on preserving two-part varnish in the fridge. However, they are a much more expensive option.

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.

Colours Available: Clear.

Pack Sizes: 1 Litre, 2.5 Litre, 5 Litre.

Coverage / Drying Times:

Surface Dry: 2 hours

Hard Dry: 8 hours

Overcoat : after 24 hours Keep coated areas dry for a minimum of 24 hours following application. Please note, drying times will be extended at low temperatures. Do not apply when ambient temperature falls below 10ºC

Theoretical Coverage: 12 – 14m² per litre.

(Coverage rate can be affected by such variables as type and condition of substrate, type of application equipment and individual method of application.)

Preparation:

Proper surface preparation is essential for the success of any protective coating system. Before you begin ensure the area is free from any dust, oil, grease, old coatings and surface contaminants.

All surfaces to be painted should be clean, dry and free from loose and flaking material, dust, grease etc.

Rub down previously gloss painted surfaces with fine waterproof abrasive paper and rinse thoroughly.

Application:

Best results are obtained in warm (minimum 10°C), dry conditions.

Mix thoroughly for approximately 2 minutes using a drill stirrer. A wooden batten at least 25mm wide is also ideal. Apply an even coat using a brush, short to medium pile roller on smooth surfaces.

For spray application by either airless or conventional spray a dilution ration of no more than 10% is recommended with Palatine White Spirit by volume applying thin coats allowing each one to dry before applying subsequent coats.

Once dried, a second coat can be applied at full strength. This will prolong the life and performance of the coating.

Thinning and Cleaning: Use Palatine White Spirit.

A minimum of two coats is recommended on bare wood to optimize the coatings performance.

Please note: The colours on the product listings are only given as a guide. This is due to the fact that every computer monitor has a different capability to display colours. In addition, everyone sees these colours differently. Sample pots are available to order upon request. Always carry out a test patch (approximately 100x100mm) before full application to ensure compatibility with previous coatings and the substrate, and to ensure the colour achieved meets your requirements. Failure to do so will result in a product refund claim not being accepted.

I Bought 1ltr of Yacht Varnish Clear High Gloss for interior and Exterior Absolutely Brilliant and Highly Recommended.

bubblesforkids – 4th May 2020

We bought this exterior yacht varnish on ebay to start with, with lockdown closing DIY stores. WOW we have been making Novelty Chalkboards for 5 years now and never found a clear varnish that didn’t show up yellow tinges. This is amazing on all levels, CLEAR very CLEAR and makes our chalkboards so hard, so will help maintain the wood. We are ordering another 5 litre today after only 1 week since last can. I cannot say how happy we are, our whites, pale pastel coloured paints are all looking how they should. Well done Palatine Paints, keep up the good work. Would be great if you could introduce COLOURED exterior paints too as we would certainly be buying these. Rosemary/Davie @ Novelty Chalkboards. Scotland 🙂

jason – 5th May 2020

Thanks Rosemary and Davie for your comments. We do coloured exterior paints! Have a browse around the website. Our two hour gloss and our Palatine Professional in matt and satin are all ideal for exterior use and can be made in any colour from the RAL Classic and BS381c and BS4800 colour charts

T Rys – 14th April 2020

I used this varnish for veranda wood construction. It was easy to apply, very efficient, nice glossy finish. Will buy again.

I have used the marine varnish on the external rubbing rails and cockpit of a South Coast One Design and found it has lasted far better than the Epifans yacht varnish or the Hempel Quick Drying yacht varnish, particularly for high wear areas.

Malcolm McGeoch – 15th January 2020

top quality in every respect (1 Litre)
