Durabak’s Coverage

One gallon of Durabak 18 (Textured) is going to cover approximately 60 square feet when you apply two coats. Proper application will give you a surface of about a 1/16th of an inch thick with the textured Durabak.

Durabak can be applied by roller, spray or even brush. If spraying, an undercoating gun, or “Schutz” spray gun is recommended. You may also need to thin your Durabak 18 with Xylene or Solvide at approximately 10%. When spraying any material, you need to account for some overspray, so you may want to budget in a little more product.


By now you are wondering exactly how much bedliner you need to get this job done. Here’s how you figure that out.

Do The Measurements

Square footage is measured by multiplying the length of the project by the width of the project. For example, if you have a 10-foot length and a 6-foot width, you would end up with a total of 60-square feet.

So, as a general rule of thumb, one gallon should be sufficient for a 6-foot pickup bed. Purchase and additional 1-2 quarts for an 8-foot bed.

Keep in mind that this calculation only provides a rough idea of your total square footage needs. For the best results, you always want to factor in a little extra for waste or surface irregularities. As noted above, if you are spraying the material, you can expect to have some over-spray.

Quick Reference to How Much Bed liner You Need

As a quick reference on how much bed liner you need for a truck, here are some quick calculations that might help. Remember, always measure the truck yourself to determine the proper amount needed:

  • Ford F-150 – If it’s a Regular Cab Ford F-150 truck with a 6-foot 5-inch bed, you would need roughly 3 gallons to cover the entire truck and bed. Plan to use a little over a gallon for the bed, and the remainder for the truck exterior.
  • Toyota Tacoma – On the Toyota Tacoma truck 5-foot bed, you need 3 quarts to cover the bed, and about 2 gallons to cover the truck exterior.
  • Honda Ridgeline – This Honda Ridgeline truck bed is generally 5-feet 3-inches. You will need 1 gallon on the bed, although you may have a little leftover to get started on the truck exterior body, which will again require about 2 gallons.

It is always better to have a little extra product on hand than not enough. If you end up with some extra Durabak, there are plenty of other ways to use it so it doesn’t get wasted. Be sure to check out our 10 Excellent Ways to Use Durabak.

Application Tips

To make the most of the Durabak you purchase, here are a few tips to help keep the waste down.

  1. Durabak is available in gallon or quart containers. This should make it easier to get the amount you need for your truck.
  2. Apply two coats of Durabak. You can opt to apply more than that; just be sure that you apply them in thin layers.
  3. If you have extra Durabak after the project is over, there are plenty of uses for it. Remember that Durabak is good for concrete, wood, metal, fiberglass, rubber, plastic, tile and more.
