FAQ – Advanced

Can products be dipped into Durabak for easier coating?

Tools have been dipped into Durabak with some success, however, sagging would be a factor in other applications perhaps.

Does Durabak coat over Sherwin Williams Exterior oil stain product?

It should bond well but a test patch is always advisable to be safe.

Would oil treated wood need to be primed?

Oil treatment normally will inhibit bonding. Use a primer designed for it and compatible with polyurethane.

Can I solvent epoxy primer be used on the metal before the Durabak application?

Yes, a product like https://www.summitracing.com/parts/SUM-UP230/ , is compatible with Durabak

How does Durabak withstand petroleum products, like gasoline, oils, and transmission fluids?

If properly maintained and cleaned, Durabak will do very well in these environments as it’s resistant to these chemicals. You would want to go with a darker color, though, like a black or dark grey. If there are issues in any specific spot, Durabak can easily be reapplied over itself for a clean finish.

How does Durabak hold up to 6,000 lb forklifts riding over it?

Assuming it’s rubber wheels, which most modern forklifts are, and that the driver isn’t constantly jerking the wheel back and forth on a specific spot, then it should hold up well. Durabak is used on many warehouse floors with forklifts going over it all the time and performs very well.

Can Durabak be applied in direct sunlight?

The Durabak18 is fine when applied in direct sunlight. The substrate mustn’t be overly hot. If it’s in the 90’s you probably ought to wait until the evening when it’s a bit cooler.

How does Durabak withstand nitric acid and other acids?

Our urethane products are able to survive permanent immersion only at pH’s between 4 and 9. Which would be something that contains like 15% nitric max. Above that, it wouldn’t work with Durabak.

What's the max substrate temp for a Durabak application?

95 degrees F

Can an epoxy be coated over Durabak?

Yes, that should work fine, as Durabak can bond to an epoxy. Just make sure to rough up the Durabak aggressively, with like 30 grit.

Can Durabak be applied over new fiberglass?

The fiberglass should be fully cured before application of Durabak.

How do you apply Duraflakes or add decorative items?

Apply 1 coat of the color of your choice (can do 2 as well), when still wet, add the decorative pieces on top. Wait for it to completely dry and then coat it with 1 coat of clear).

What should I do if Durabak starts to bubble over?

This may happen in areas of very high humidity, like above 70%, (or possibly even less). You should stir the can for 10 minutes, and then let is sit for 10 minutes, and the bubbles should hopefully dissipate. If not, repeat, until the bubbles have settled. When pouring out into a tray or larger bucket, pour slowly. It’s also best to do your application earlier in the day or later in the day, when the humidity is lower.

If the Durabak is tacky after a while, can I apply a 2nd coat?

If it’s on the dry side of tacky, then you can. Meaning, if no paint comes off onto your hand when you touch it. However, you may want to use an accelerator in the 2nd coat when applying in order to facilitate a better curing on both coats.

If the Durabak is still tacky after a few days, what should I do?

Durabak needs 40% humidity to cure. So if it’s below 30% humidity, you should use an accelerator. If the application has already happened, then you should bring a humidifier into the room, you can also spray mist in the air- but just make sure not to get it on the surface with the Durabak, or you can put wet rags around the area.

Will Durabak stick to HDPE, High Density Polyethylene?

No. There will be no chemical bond to this material, only mechanical adhesion is possible. We have not had much success with polyethylene ever. Unless you can find a special primer that will provide adhesion, Durabak will be problematic. There is the possibility that, with some heavy sanding with a P100 or coarser sandpaper and a solvent wipe, sufficient adhesion will be obtained, but it’s definitely a challenge.

What's the best prep and application for Durabak as an undercoat?

It should be roughed up with 30 to 40 grit as well as possible and sprayed on with an undercoating gun.

Can Durabak be applied directly onto thin carpet, like on a boat?

It’s been done previously. The carpet should be dry and then it should bond extremely well.

How do you prep the surface before a clear coating? If you rough up the surface, won't that be seen through?

It depends on the surface. If being applied to wood, which is naturally rough, a light scuff, with no primary will do the job. If on a vinyl tile for example, you’ll need to be more rough, which wouldn’t make sense to do if it’s a designed tile… so really depends.

If concerned that exisitng coating is peeling or flaking, does it all need to be stripped, or will Durabak seal the existing painted surface?

It’s always best to apply Durabak to the most solid substrate as possible, so the entire surface should be stripped.

Can Durabak be applied after a sulfuric acid wash on the aluminum?

Aluminum should be primed regardless, so sulfuric acid wash and rinse followed by a aluminum etching primer.

Can Durabak be applied over POR 15?

Durabak is quite compatible with POR 15. Rough it up with 80 grit, wipe with xylene and apply Durabak.

POR 15 is a popular protective coating for the industry and Durabak adds durability plus other features.

Does Durabak bond to primed steel directly?

Normally Durabak will bond to any primer with a light scuffing (80 or 100 grit). It’s always a good idea to do a test patch prior to the general application. Xylene is not used on primers.

Can the Durabak be baked to either accelerate cure time, or in general, withstand the process if the substrate needs to be subjected to that?

The company applying Durabak to Penske trucks applied Durabak to steel rectangles and suspended them from an overhead conveyor. They then ran them through a verticle heating mechanism (much like the old fashioned toasters) only the heating elements were from floor to ceiling. The Durabak was dry in 5 minutes. However, a trial must be done since the temperature can vary widely, and the time from when the Durabak is applied can also vary.

Should xylene or a solvent be used on a surface before application of Metcote?

The surface should be roughed up and cleaned well from all residue. A solvent doesn’t need to be used, but it’s not a problem to use, as long as it’s completely dry before metcote application

If a primer was applied a while ago, can I just rough it up, and apply the Durabak?

No, primer’s don’t work like paints, and they can’t just be roughed up and overcoated. One must follow the timeline provided by the primer for overcoating, and with Durabak one should target the beginning 1/3 time window.

Does Durabak leach or let out pollutants when sitting in water?

Once cured, Durabak doesn’t leach, so no pollutants.

Do tires need to be rebalanced after being coated with Durabak?

It is advised.

Can Durabak be applied over the oil based Rustoleum?

If the paint is sound on the surface, clean off surface dirt, rinse with water, score with an 80 grit sandpaper and coat. No primer is needed.That’s all!

Can an air- powered gun be used with the smooth Durabak?

An air-powered spray can be used with smooth. It will put more air into the product, but the coats can be thinner with a spray gun, so a defect-free coating can be achieved. Thin the product adequately with xylene, keep the coats thin and it will be fine.

How are sample chips applied?

Both smooth and textured sample chips are applied with a roller.

Durabak 18 vs Durabak

‘-It lasts much longer before a maintenance coat is required -It dries faster -It does not yellow or fade.

How do you prep cold rolled steel?

  1. Removal of the protective oil in which it is supplied by means of a solvent cleaning
  2. Application of a 2K epoxy primer according to manufacturer’s instructions (which may include a light sanding)
  3. Application of two successive coats of Durabak at a wet film thickness of 400 microns or alternatively 2 ½ square meters per litre. (which is approx. 100sq.ft per gallon – thin coat)

How does Durabak bond to EPDM ethylene propylene diene monomer rubber?

Durabak bonds very well to it. Our Safti trax are from EDPM, as well as the rubber samples we create.

What's the HS code for import tax and tarif purposes?

3208.90.90.4

What's the required prep on cold rolled steel?

If the cold rolled steel has been in use for a while and the protective layer of oil has been removed then a 2K aluminium primer would work, but some roughening is also required. If the coating goes right around the roller it should shrink on, which helps. An etching primer won’t bite into hardened steel, and would fail.

My Durabak is very thick, do I have a bad batch?

The consistency 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 not, it may be a bad batch.

Does Durabak act as a conductor of electricity?

No, Durabak won’t conduct electricity, rather it will act as an insulator.

How do I prepare my surface for Durabak?

All surfaces must be clean, dry and rough. For specific surface preparation Consult your product manual or a Durabak™ representative. We have advanced guidelines for applying Durabak™ to a number of commonly used surfaces here.

How do I test if my surface is ready for an application of Durabak?

Before applying Durabak, always do a small test for adhesion:

a. clean surface, rinse with water, and let dry

b. roughen surface with 40-grit sandpaper

c. wipe with Xylene, Aromatic 100 (ARO 100) or Oxsol 100 on a rag to remove any residue left from cleaning

d. apply 1st coat of Durabak and let dry

e. apply 2nd coat of Durabak and let dry for 2 days

f. take a screwdriver and try to peel the Durabak off the surface

g. if it comes up in small pieces, you have a good bond

h. if it comes up in sheets, you need to re-prime according to manufacturer’s instructions

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″.

Important- Ensure that the compressed air lines have efficient water traps. Wet compressed air will harden the Durabak in the gun.

Spray Vs Rolling

Spray provides a more even distribution of rubber granules, but it’s more challenging, and should only be done with some experienced with an undercoating or Shutz gun, which can be picked up at automotive store for $25. For smooth Durabak you can use a standard spray gun for application.

How much coverage will I get with one GALLON of Durabak?

A gallon of textured Durabak will cover approximately 50-60 square feet with 2 coats.
A gallon of smooth Durabak will cover approximately 75-80 square feet with 2 coats.
The coverage is dependent upon the surface porosity.
1 gallon of textured will cover a 6′ short bed, including the floor, side, front panel and tailgate.
While 1 gallon and 2 qt would be needed for an 8′ bed
2 gallons of smooth will cover the outside of a truck in 2 coats.
While 1 gallon will do an entire jeep in a double coating.

How much coverage will I get with one QUART of Durabak?

A quart of textured Durabak will cover approximately 12-15 square feet with 2 coats.

A quart of smooth Durabak will cover approximately 19-20 square feet with 2 coats.

The coverage is dependent upon the surface porosity.

How do I measure Square footage?

Square footage is measured by multiplying the length of the project by the width of the project. For example: 10′ (length) x 6′ (width) = 60 sq ft

How much product should I purchase?

One gallon for a 6′ pickup bed and two gallons for a long bed.

One gallon covers approximately 50 to 60 sq ft with the standard two-coat application.

Can I 'get away' with applying only one coat of Durabak?

No, you should always apply 2 thin coats of Durabak. It is always better to apply more thin coats rather than 1 thick coat. This will keep the integrity of the urethane and will avoid trapping CO2 bubbles.

Can I apply more than two coats of Durabak?

Normally 2 thin coats will suffice. Additional thin coats can be added for more durability or water resistance, as long as they are applied in thin layers.

What is the approximate thickness of two coats?

Approximately 1/16th of an inch for textured (approx 24 mil) with 2 coats, and it’s negligible for smooth, it’s like a standard paint from a thickness perspective.

How long do I need to wait between coatings?

Durabak dries based on exposure to air and humidity. So in more humid environments, like Florida, the second coating can be applied within an hour, while it may require up to two hours in more dry climates like Colorado.

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?

Durabak comes in textured, smooth, indoor (Original Durabak) and outdoor (Durabak UV) versions. Durabak M26 is formulated for military use.

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?

Durabak can be tinted only with a non water-based paste pigment. (Adding a water-based pigment will cause a severe bubbling reaction with Durabak.) The Durabak would then have to be applied the same day since the Durabak would have been exposed to air and moisture causing the curing process to begin. 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.

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?

No. Chlorine will fade the color in your Durabak and chlorine attacks the chemical composition of Durabak and will damage the coating.

How do I clean Durabak coated surfaces?

Durabak can be cleaned with most common household detergent and degreasers. Organic stains can be cleaned with a quaternary cleaner, but be sure to not use chlorinated cleaners (Clorox) as they may affect the color of Durabak. For more information please see our Care & Maintenance page.

Does Durabak require a primer?

In most cases Durabak products do not require a primer. A primer may be necessary for some metal applications. An adhesion test is always recommended (se above). Consult the Product Manual or a Durabak Depot representative for more information.

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 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.

What's the shelf life of Durabak?

We highly recommend applying Durabak within 6 months of purchase, but will warranty an unopened can to be free of defects for up to 12 months. However new or old your can of Durabak is be sure to mix it really thoroughly before use as there are solids inside that may have separated out and sunk to the bottom of the can.

Does Durabak come in 5 gallon containers?

No, generally it does not. Five gallon containers can’t be sealed properly for this moisture cured product.

What type of sandpaper should I use to roughen the surface?

40 grit sandpaper should be used for preparing the substrate. This will give it enough of a profile so that the Durabak will attain a mechanical bond as well as a chemical bond. Use 80 grit sandpaper for overcoating Durabak.

What are the temperature limits of Durabak?

Durabak has been tested as low as -40 degrees Fahrenheit and can withstand continuous temperatures of 240 degrees Farenheit with no adverse reactions. It is recommended to apply Durabak in temperatures between 32 and 95 degrees Farenheit with humidity above 40%.

Can I return unwanted/unused Durabak?

Yes, within 30 days only if the can is unopened and in re-saleable condition. Customer will be charged the shipping and ‘Call Tag’ fees associated with the return. As per FedEx and UPS only a HazMat authorized shipper can ship Durabak which is why we must arrange for the Call Tag and shipping. All returns must be pre-approved by your Durabak Depot representative.

How does Durabak ship?

We ship most orders within 1-2 business days via domestic ground carriers such as FedEx or UPS. For larger orders, usually 28 gallons or more, it may be feasible to use a truck line freight carrier. You can also request your own shipping method and we will try to oblige. Delivery charges are extra.

How do I get additional information?

You can e-mail or call us for a free brochure (be sure to specify color sample chip you would like to see).

Can I apply Durabak if it's going to rain?

Recommended to wait for a nice dry day, but if it is absolutely necessary to apply earlier, then at least have 6 hours after the second coat has been applied of day dry time.

Does Durabak prevent rust?

When the surface is rust free, Durabak’s tight bond will normally inhibit future rusting, if it’s properly double coated.  Priming could help, but if there is rust prior to the application, customers should remove it using a chemical rust neutralizer prior to the application.  That should be available at a local industrial paint or hardware store, such as Home Depot. No specific brand recommendation, just check the label for comments pertaining to timing and if there are any precautions about top coating.

Does Durabak need to be cleaned? Will there be negative impacts like cracking or peeling if dirt isn't removed?

Dirt won’t actually harm the product, so it is not more likely to crack when left dirty. It shouldn’t have any effect on whether it peels either.

Can I apply Durabak to my warehouse floor?

We would recommend doing samples tests in multiple areas of the warehouse before proceeding with a full application, as different areas may bond while others don’t. For example, some area may have oil, which would need to be removed with oil emulsifiers.

Does Durabak run when applied on vertical surface? If coloring the body with 2 different colors, should it dry before applying 2nd color?

Two colors can be applied either at the same time using a 3m blue tape to separate the 2, or you certainly can wait until until the first color dries before applying the second. Both options have worked well in the past.

Is Durbak non heat absorbing? Will it prevent a boat from heating up?

We don’t have any test data to determine that it is officially non heat absorbing. However, just naturally by putting a coating (in a light color) over bare aluminum it will have the effect of reducing the heat to the feet. Certainly you can apply an additional coat or two for additional cooling effect.

Can I accelerate the drying process?

Yes, Durabak offers an accelerator for both its UV and non-UV product, which accelerates the drying process by about 50%. (Non UV should strictly be used on the Durabak non UV, and vice versa)

Is there any activator?

No, Durabak is moisture-cured product, which means the air and the humidity in the air are the actual activator.

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?

No. Due to hazmat requirements, we only ship ground.

Does Durabak ship to Alaska or Hawaii?

Furabak 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 Durabak heat resistant?

Durabak will withstand 200°F. Durabak is fine as an undercoating but normally not near the exhaust pipe.

How do I place an order?

You can purchase products directly from our secured shopping cart using MasterCard, VISA or Discover at DurabakCompany.com. Or you can give us a call at (303) 690-7190 to place an order.

How do I set up a business account for ongoing orders?

Please email our account manager, David@DurabakCompany.com

Where can I find the batch #?

Batch # can be used if your have quality issues, as we can check it against the sample that’s retained by the manufacturer. The batch # can be found on the bottom of the can- and will be on the side of the can soon as well.

Does Durabak prevent rust?

When the surface is rust free, Durabak’s tight bond will normally inhibit future rusting, if it’s properly double coated.  Priming could help, but if there is rust prior to the application, customers should remove it using a chemical rust neutralizer prior to the application.  That should be available at a local industrial paint or hardware store, such as Home Depot.

Dirt won’t actually harm the product, so it is not more likely to crack when left dirty. It shouldn’t have any effect on whether it peels either.

What's the life of the product?

The life of the product will vary extensively. It will depend upon type of useage, weather conditions and a multitude of factors. As a bedliner exposed to heavy abuse perhaps 5 years…with light use perhaps 10 years. It can also be touched up as needed to extend the life. I usually tell customers that it could be 5, 10 or 15 years depending on use, but it’s impossible to specify the life. Textured is considered more durable so it is likely to last longer than smooth, but there’s no good way to put a time frame on either one.

What's the shelf life of Durabak?

We highly recommend applying Durabak within 6 months of purchase, but will warranty an unopened can to be free of defects for up to 12 months. However new or old your can of Durabak is be sure to mix it really thoroughly before use as there are solids inside that may have separated out and sunk to the bottom of the can.

Can Durabak non-UV be used inside a van?

Non UV should be fine inside of the van. Sunlight shining through windows or when the doors are open is unlikely to cause fading… of course, no guarantees, anything is possible…

Can Durabak be used to waterproof, like for an RV roof?

Although, we don’t actually advertise Durabak as being waterproof, nor do we provide guarantees on it, many customers have used Durabak on RV roofs as it is “highly water resistant” and in just about all cases over the years it has done an excellent job. You probably should add a coat or two to give it additional water resistance.

Can the surface be cleaned with bleach before applying Durabak?

Yes, but the recommended prep procedure must still be followed subsequently, including roughing up the surface, and wiping it with xylene.

Can Durabak be cleaned with bleach?

No, we do not recommend using bleach to clean Durabak. Normally cleaners such as Spic n Span and other household cleaners will do the job.

Does Durabak prevent Asbestos?

When one uses a coating for encapsulating asbestos (or for that matter lead), an air quality test for asbestos should be performed by a certified technician. When Durabak is used for asbestos encapsulation, it seals the area. Since it is an impermeable membrane, no asbestos particles can escape. However, to certify that no asbestos escapes into the air, an outside agency would have to do that certification. Each application is case specific. Of course the effictiveness of the Durabak at sealing off the asbestos is dependent in large part

How do I remove mildew that's growing in Durabak?

Mildew can sometimes develop when Durabak is applied in thicker coats, as when the CO2 releases on the bottom coat, it may get stuck and create a bubble, crevice area which mildew can grow in. #1 approach to remove it is a good household detergent. There are also mildew preventatives that can be added to Durabak at time of application, like anti bactericides.

What is M26?

It provides a higher flashpoint than the regular Durabak. It meant for navy purposes, as they require it to be Mil Spec and Navy QPL (Qualified Product List)

Is Durabak considered Hazardous material?

Yes, it’s Class 3 hazardous. Not an issue with ground, but it prevents us from shipping air, and makes it difficult to do sea. If forwarding the freight, the forwarded will need to do hazmat paperwork for the sea.

Hazmat classification is UN1263, PAINT, Class 3, PGIII

What are box sizes?

Regular box can fit 4 gallons- ~40lbs – 14in x 14in x 8in

Qt box can fit 12 qt – 30 lbs- 15x11x8

What color is the primer?

Primer is beige, and there is no color choice

What can be used as a substitute for xylene, in locations like California, where xylene can't be sold?

a) Aro 100

b) Oxsol 100

c) Klean Strip Industrial Maintenance Coating thinner (can be found in most paint stores, including Home Depot)

d) Polane by Sherwin Willians- sold in their outlets

e) Pro Thinner Diluyente Specialty Thinner – produced by Crown

f) Xylene- produced by Crown (can be found in Lowe’s)

g) There are some sellers on ebay that will ship xylene to California- you can check out https://www.ebay.com/itm/282680633700?ul_noapp=true for example

h) Customers have also recommended https://www.kbs-coatings.com/Number-1-Thinner.html

Can I use non-UV as an undercoat, and the UV Durabak as the 2nd coating?

This is a good option for customers who are trying to save a little money. The results are the same and longevity is the same as well. However, make sure that the Non-UV is completely dry before applying the UV overcoat- not just the usual 1 hr between coats

What's your return policy?

Within 30 days, if the Durabak was never opened it can be returned, but we do not refund the initial shipping charge, and customer is responsible for the return shipping charge, which may include an extra call tag fee. There’s also a 20% restocking fee charge.
