Advanced Frequently Asked Questions about Durabak
How much Durabak do I need for my Boat deck?
If you like to go rough, and grip is your number one priority, go with 2 coats of Textured Durabak for an unbeatable non-slip deck. If you really want to go all out on grip, you can also order DuraGrip Silicon Carbide that can be added to the Durabak for an exceptionally rough surface.
If, on the other hand, you want something that has grip but is also easy to clean and slightly more gentle on your bare feet, many boaters recommend laying down a first coat of Textured Durabak followed by a top coat of Smooth Durabak.
How much you need:
Measure the width and length of the areas that needs to be coated to get your square footage requirements.
Textured Durabak covers 60 sq.ft per gallon, Smooth Durabak covers 75sq.ft per gallon.
So if you have 150sq.ft to cover and you want the grippy Textured only finish you’ll need 2 gallons and 2 quarts of Textured Durabak.
If you want to cover the same 150sq.ft with one coat of Textured and one coat of Smooth Durabak, you’ll need one gallon and one quart of Textured for the first coat and one gallon of Smooth Durabak for the top coat.
If your budget allows we always recommend erring on the side of caution, as if you ‘underbuy’ you may end up with a finish that is not professional and you’ll need to order more product and wait till it arrives and do a little more prep to finish the cop coat, whereas if you ‘overbuy’ worst case scenario is to have some incredible Durabak lying around that can be used for thousands of applications on your boat, truck or many other places!
How much Durabak do I need for the exterior of my Ford F-150, Dodge Ram, Chevrolet Silverado, or other large truck?
Two gallons and a quart or two of Smooth Durabak should be enough to coat the exteriors of these larger trucks.
BUT, please take the time to get out a tape measure and measure the body panels surface area in square foot.
Make sure you got every panel on the truck, add up all the sq.ft and then divide the total square footage by 60 for textured, or by 75 for smooth and then you’ll know how many gallons you’ll need.
If your budget allows we recommend always purchasing a quart extra because if you run out before the job is finished and have to wait a few days to finish the last of the top coat the application will not be as professional as it should be.
Don’t worry, even if you don’t need that extra quart, there are thousands of things you can do with it like; rims, bumpers, wheel wells, rock sliders, roll bars, racks, undercoating and it’s great, resilient non-slip paint so you can use it for thousands of things at work, in the garage or around the home too.
How much Textured Durabak do I need to cover my Jeep?
One gallon of Smooth Durabak would also be enough to cover an entire (2 door) Jeep.
Larger Jeeps and 4 door Jeeps we would recommend 2 Gallons of Textured Durabak to coat the exterior.
If you want to paint the tub of your Jeep you should be able to do it with a gallon of Durabak.
How much Durabak do I need for my Truck Bed?
“Regular” Beds are 5’7 to 6′ long, you’ll need one gallon of Textured Durabak to do the minimum 2 coats.
“Long” Beds are around 7′ long, you’ll need one gallon and one quart of Textured Durabak to do the minimum 2 coats.
“Extra Long” beds are around 8′ long, you’ll need one gallon and two quarts of Textured Durabak to the the minimum 2 coats.
For a Flat Bed we recommend you measure the surface area of the entire area you plan on painting, make sure you included all the rims and sills, and then work out the total square footage that you need to cover. A gallon of Textured Durabak will cover 60 square foot in 2 coats and a quart will cover 15 square foot. So divide the total square footage by 60 to work out how much Durabak to buy.
e.g. Flat bed is 8.5 feet wide and 48 feet long with 18 inch sills along the sides.
8.5 x 48 = 408sq.ft
+
48 x 2 (sills on both sides) x 1.5 (18 inches) = 144sq.ft
408 + 144 = 552sq.ft
552/60 = 9.2 = 9 gallons and one quart of Textured Durabak.
If you’re going for Smooth, so divide the total square footage by 75, so for the same flat bed as above we would do…
552/75 = 7.36 = 7 gallons and 2 quarts of Smooth Durabak
How can I check that Durabak will work for me?
If in doubt what you’re working with we recommend an adhesion test before your big project. Order an extra quart with your order for the adhesion test. Look below for the full guidelines for other popular materials.
Durabak Adhesion Test
Before applying Durabak, always do a small test for adhesion:
-Clean surface thoroughly with a non-chlorinated detergent.
-Roughen surface with 40-grit sandpaper
-Wipe with Xylene
-Once completely dry, apply 1st coat of Durabak
-Once touch dry (normally 1-2 hrs), apply 2nd coat of Durabak
-Let dry for a couple of days.
-Take a screwdriver and try to peel the Durabak off the surface. (The Durabak isn’t fully cured yet, so you should be able to get under it).
-If it comes up in small pieces, you have a good bond.
-If it comes up in sheets, you need to prime with something compatible with the substrate, and which can be overcoated with a polyurethane.
-Repeat the adhesion test with the new primer.

Can I patch up and fix Durabak? How do I re-coat Durabak?
Durabak Reapplication
Durabak can always be applied over itself, whether you’re looking to smooth out the texture with the smooth Durabak, or interested in changing the color, you can simply add 1 or 2 coats over the existing Durabak.
The required surface prep, will depend on when the previous coat was applied.
2 days – 6 weeks:
-Lightly rough up the surface, like with 100 grit
-Very gently wipe with xylene.
6 weeks & Longer:
-Aggressively rough up the surface, with 40 grit
-Gently wipe down with xylene.
How do I apply Durabak onto Epoxy?
Epoxy Surface Application
Equipment
-2 stipple roller sleeves per gallon (Included with purchase of textured gallon) or short nap roller, like a 3/16” mohair or similar for a smooth application.
-36 grit Sandpaper
-Stir stick or electric paint mixer
-Roller Tray
-Cloth or sturdy cotton rag
-Paint Gloves
-Household non-chlorinated detergent, like Spic n Span
-3M Blue tape (Optional)
-Paint Respirator (Optional)
-Primer (Optional)
Surface Prep
-Clean the surface thoroughly, with a non-chlorinated household detergent
-Rough up the surface with 36 grit sandpaper
-Wipe down the surface with xylene on a cloth and once completely dry, apply the Durabak.
Application Process
-Do not open can until surface is prepped and ready to go.
-Then open can and stir well.
-Pour a portion into a roller tray and begin application.
-Roll on first coat of textured using Durabak stipple roller sleeve, or a short nap roller for the smooth Durabak.
-Use a paint brush in corners and hard to reach areas.

-Keep lid on can while not in use.
Coverage
1 gallon of smooth Durabak covers roughly 75-80 square feet in our standard 2 coat application.
1 gallon of textured Durabak covers approximately 60 square feet in our standard 2 coat application.
Good to Know
-Durabak begins to cure with exposure to air, so minimize exposure to air while working with it.
-The consistency of the Durabak should be runny, as it’s self leveling. If it’s thicker, you can add up to 15% xylene to thin it. It should be mixable after adding the xylene and back to a runny form. If it’s pasty and thick, DO NOT APPLY, rather reach out to us for assistance.
-You will have a few hours of work time once the can is opened (3 to 5 hours normally).
-A second coat can be applied after 1-2 hours, once the first coat is touch dry.
-After second coat is applied allow 24 hours before walking on it. Complete cure is about 5 or 6 days, so no heavy use until then.
Additional Tips
-Temp should ideally be 60 degrees or above for the application, and above 40% humidity.
-Xylene should be applied immediately to clean up any misapplied Durabak.
-If taping off, use 3M Blue tape and remove immediately after second coat is applied at taped off edges, then continue with general application of the second coat.

How can I put Durabak on Concrete (floor)?
Concrete Application
Surface Prep
For best results
New concrete prep:
– Be fully cured, for at least 28 days.
– Have a brush finish.
– Be hand troweled (If already power troweled, test for adhesion.)
– Be thoroughly cleaned with a citric cleaner or equivalent, rinsed with water, and thoroughly dried.
– Be wiped with Xylene and the Xylene be allowed to dry immediately before applying Durabak.
NOTE:
– If the new concrete contains plasticizers, a small test for adhesion is essential as a primer may be required.
Old concrete prop:
There are three ways to prep old concrete.
-Either:
A. Shotblast, if possible, and rinse with water.
OR
B. Abrade with a scarifying machine (leaving a rough surface) and brush off.
OR
C. Thoroughly clean with muriatic acid wash:
- Use 45% to 50% muriatic acid solution mixed with 3 to 4 parts water.
- Agitate solution on surface with a hard-bristled deck brush for approximately 10 minutes, to open pores on surface.
- Rinse off with a 5% ammonia/water solution to neutralize acid. (Failing to neutralize acid could leave residue which might cause delamination.)
– Let completely dry. If necessary, use a heat source.
– Brush off to remove all residue.
-Wipe well with xylene immediately before applying Durabak. Let the Xylene evaporate before applying Durabak.
NOTE:
- If the old concrete contains plasticizers, a small test for adhesion is essential, as a primer may be required.
Oil-Soaked Concrete
- Open pores of concrete with muriatic acid and rinse, as above.
- Apply an oil emulsifier and agitate with deck brush for 10 minutes.
- Rinse with hot water.
- Rinse twice with cold water.
- Dry completely.
- Wipe with xylene immediately, and then let the Xylene evaporate before applying DURABAK™ or DURABAK 18™.
NOTE: For chemically soaked concrete or other unusually difficult surfaces, contact Durbak Company.
Sealed concrete should first be tested for DURABAK™ adhesion:
- Clean surface thoroughly.
- Roughen surface.
- Brush surface off thoroughly.
- Rinse with water and dry thoroughly.
- A Xylene wipe is recommended. Let Xylene evaporate.
- Apply DURABAK™
- If delamination occurs, sealer must be removed by mechanical means (i.e., shot blasting or scarifying).
While it is not usually needed on concrete, a primer can provide enhanced adhesion.
Contact Durabak Company for specific information on surfaces to be primed.
Application Process
-Do not open can until surface is prepped and ready to go.

Surface Prep
-Clean the surface thoroughly, with a non-chlorinated household detergent
-Rough up the surface with 40 grit sandpaper
-Wipe down the surface with xylene on a cloth and once completely dry, apply the Durabak.
Application Process
-Do not open can until surface is prepped and ready to go.
-Then open can and stir well.
-Pour a portion into a roller tray and begin application.
-Roll on first coat of textured using Durabak stipple roller sleeve, or a short nap roller for the smooth Durabak.
-Use a paint brush in corners and hard to reach areas.
-Stir occasionally while working with the product.
-Keep lid on can while not in use.
Coverage
1 gallon of smooth Durabak covers roughly 75-80 square feet in our standard 2 coat application.
1 gallon of textured Durabak covers approximately 60 square feet in our standard 2 coat application.
Good to Know
-Durabak begins to cure with exposure to air, so minimize exposure to air while working with it.
-The consistency of the Durabak should be runny, as it’s self leveling. If it’s thicker, you can add up to 15% xylene to thin it. It should be mixable after adding the xylene and back to a runny form. If it’s pasty and thick, DO NOT APPLY, rather reach out to us for assistance.
-You will have a few hours of work time once the can is opened (3 to 5 hours normally).
-A second coat can be applied after 1-2 hours, once the first coat is touch dry.
-After second coat is applied allow 24 hours before walking on it. Complete cure is about 5 or 6 days, so no heavy use until then.
Additional Tips
-Temp should ideally be 60 degrees or above for the application, and above 40% humidity.
-Xylene should be applied immediately to clean up any misapplied Durabak.
-If taping off, use 3M Blue tape and remove immediately after second coat is applied at taped off edges, then continue with general application of the second coat.

What can I use to apply Durabak?
Durabak can be applied with a spray gun, brush or roller. When rolling on the Durabak textured version use our special Stipple roller sleeve. For the smooth version, you can use any 3/16 Nap Mohair roller.
When applying with a spray gun please see our Spray Application instructions for more information.
Can Durabak be sprayed?
Yes, textured can be sprayed with with most conventional spray equipment but it requires a large tip (1/4″) and should be thinned with Xylene approximately 10%.
Smooth can use a standard spray gun with a tip size of .021″ – .023″. (21-23 thou.)
Important- Ensure that the compressed air lines have efficient water traps. Wet compressed air will harden the Durabak in the gun.
Be sure to wear a breathing mask with a filter when spraying Durabak.

I have some Durabak left over. How should I preserve it?
Once a can of Durabak™ is opened you should use the entire contents since the product begins to cure with exposure to air. Durabak™ should not be resealed for future use.
The only suggestion we can make, though, is you can transfer the remaining contents to a smaller container, so that it’s a full container, with minimum room for air, and then seal it up.
What are the different versions of Durabak?
Can I mix 2 colors of Durabak to achieve a custom color?
Like versions of Durabak (Durabak 18 with Durabak 18 or Original Durabak with Original Durabak) can be mixed together to achieve a desired color. (NOTE: Original Durabak and Durabak 18 cannot be mixed together.)
It is important to stir the contents of the can very well since shaking alone will not mix the contents thoroughly.
Custom colors can be produced to any standard, given sufficient lead time and a minimum order of 75 gallons.
Can I tint Durabak to achieve a custom color?
Does Durabak have tinted pigment?
No we do not. Many customers do add a quart or two of the smooth Durabak to adjust the color.
However, if they truly want to customize the color, some customers in the past have gone to an auto body shop to get a urethane tint.
Durbak Company are not responsible for the results.
The urethane tint must be compatible with a moisture-cured, one part polyurethane.
Note- Durabak is initially made as a clear solution, and then has 250 grams of pigment added to it to achieve a specific color. To add tint, would require a significantly smaller dosage as you’re only modifying existing pigment, and not creating new. Certain colors are more difficult to tint, like white has lots of pigment, and therefore isn’t a great choice for tinting. (Dark Grey is good for tinting black, and sand/beige is good for tinting red)
Can I use Chlorine or chlorine based cleaners on Durabak?
How do I clean Durabak coated surfaces?
Does Durabak require a primer?
What's recommended for primers?
For bare aluminum or bare metal, Zinc chromate is usually available at an industrial paint store. We do not have any test data regarding zinc chromate. It is simply based on past customer feedback that we recommend it. You can also use a metal etch primer that is compatible with polyurethane (Durabak is a moisture-cured, 1 part polyurethane). Durabak also has a primer (1 quart covers approximately 2 gallons worth of Durabak). Other urethane primers also work pretty well.
For Fiberglass, a two part water based epoxy should be used.
What is used to clean up or thin Durabak during application?
Only use Solvide, Xylene, Aromatic 100 (ARO100), Fluidar or Oxall which can be obtained at coating/paint stores or hardware stores.
Durabak can be thinned with up to 15% of Xylene, Aromatic 100 (ARO100) or Oxsol.
The consistency of Durabak should be “Drippy” but not “Runny”. Durabak is self leveling.
How comfortable is Durabak on bare feet?
Most people say it is comfortable as there is some “give” with the rubber tire granules and there are no sharp edges. You can even customize Durabak by adding smooth Durabak to the textured Durabak. For instance, if you add 1 gallon of smooth Durabak to 1 gallon of textured Durabak you will essentially have 50% less texture on your application.
Of course smooth Durabak is totally smooth so there’s no question of comfort.

Does the smooth leave brush strokes?
Normally smooth goes on very nicely with a short nap roller (3/16″ mohair or similar). Generally speaking you will not see strokes but smooth is more sensitive than textured.
The rubber granules make textured more forgiving and will not show strokes whereas smooth does require a little more skill and care by the person applying it.
Do we offer next day shipping?
Does Durabak ship to Alaska or Hawaii?
Durabak is considered a HazMat product, which means it cannot be shipped by air.
Therefore shipping to Alaska and Hawaii requires that it go by boat. That is a lot of extra cost.
We will ship via regular ground transportation to Seattle (or LA for Hawaii). You will need to set up an account with a freight forwarder to have it shipped to you. Please be aware that it is expensive and takes time.

Is the only difference between UV and non-UV aesthetics?
If non UV is applied indoors without exposure to sun then it will perform just as well as outdoor UV Durabak-18 and there is no difference.
If non UV is applied outdoors with exposure to sun then it will not only be an aesthetics issue by fading, but the urethane will actually degrade and it will not hold up to wear.
Is Gluvit Epoxy sealer compatible with Durabak?
No, unless 1st coated by Epifanes Multi Marine Primer before applying Durabak. Procedure as follows:
1. Prep boat surface: Sand, Acetone, Soap Water and dry thoroughly. Make any repairs with larger holes, rot around drain, etc. sand and clean.
2. Apply Gluvit (epoxy sealer) and let cure for 7-14 days based on current humidity (60’s during day and 40-50’s at night).
3. Epoxy will cure with a “amine blush” residue that will surface after full cure. This will require acetone cleaning, soap water scrub down, dry and then follow with a 120 grit sanding, soap water and dry again.
4. Marine primer then can be applied, cure for 2-4 days, sand with 320 grit, apply 2nd coat, sand again with 320, wipe down with a denatured alcohol and lint free towel which will help remove any moisture remaining in the primer.
5. Apply Durabak final coat(s).

Why is there bleeding through on 2 coats of Durabak from the below caulking?
If you can get hold of some mica and add about 20g per quart or 80g per gallon of D18 that would solve it without the need for a primer. This may be too much to ask, so you’ll need to find a locally available primer that contains mica or something similar that has blocking characteristics.
Whatever it is that is bleeding through will get through any organic film whether it be epoxy, acrylic or urethane. Only by adding some inert, inorganic filler powder will one prevent this.

How can I remove the glossy sheen to create a more matte finish?
If choosing the sandpaper route it would be a fine P400 paper.
However the better way is adding a fine powder like talc. About 10% by weight would make it matte.
Ensure it is dry and have some xylene on hand to thin it because it will cause some thickening.

Can Durabak be applied over the oil based Rustoleum https://www.rustoleum.com/product-catalog/consumer-brands/professional/high-performance-protective-enamel/?
Why would rust be forming on the Durabak when it was applied on a rust free surface?
1. water being trapped below the Durabak when it was applied. or,
2. no water being trapped below the Durabak, but entering from channels created in the Durabak after it was cured. This could happen if it was applied too thick in those areas and CO2 gas was slow to release and created channels.
The solution, I believe is to sand down those rusted areas to the steel and apply two very thin coats of Durabak with a small paint brush.
Can I Paint Durabak on rust?
First of all you have to remove any lose and flaky rust entirely, so that you only have hardened surface rust.
You’ll need to isolate the rust and seal it with a chemical rust neutralizer that will turn it black, like SEM’s Rust Stop.
The Rust neutralizer will act as a primer, so you won’t need any further primer on top of that, and you can paint Durabak straight onto the Rust treatment during the first 1/3rd of the time they recommend to overcoat. Be sure that the Rust neutralizer you use is polyurethane compatible, most of them are polyurethane based so it shouldn’t be a problem.
