Why Choose Durabak Truck Bed Liner?

Here's what you get when you choose Durabak as your truck bed coating:


Durabak is resistant to water. This makes it a good choice for bed liners constantly exposed to wet conditions.

UV- and Chemical-Resistant 

Durabak is not reactive with any chemical, making it a safe choice for trucks transporting reactive materials. 

Does Not Flake or Peel

Unlike most automotive paint, Durabak truck bed liner doesn’t peel or flake with time, guaranteeing durability and extended useful life of your truck bed. 

Sound Dampening 

Durabak bed liner coating comes with sound dampening capabilities. This allows you to transport metallic items without too much noise. 


For slippery truck beds or those constantly exposed to liquids, Durabak can help improve traction to prevent slips.

DIY-Friendly Paint 

With Durabak truck bed coating, everything is done for you – there's nothing else to mix it in, so there’s no room for error. The special formula is also user-friendly and anyone can apply it.

The paints also need little to no maintenance – a little soap and water will work just fine. 

Truck Bed Coatings

Customers who purchased Durabak truck bed liner also purchased:


Xylene (or xylol) is used for nearly all Durabak applications. 

For an extended drying time for a hard, glossy layer, Xylene is a good alternative to Toluene to thin oil-based paint, varnish, lacquer, epoxy, synthetic enamels, and adhesives. Xylene is also a good solvent for cleaning up tools, equipment, and spills immediately after painting. 

Don’t use the Xylene as a general-purpose cleaner as it may soften or damage synthetics, plastics, linoleum, fiberglass, asphalt tile, rubber, and many other finishes. It's recommended to do a patch test before application. 

Durabak Liquid Accelerator 

Depending on the weather conditions, Durabak Accelerator can reduce drying time by up to 50%. This is especially handy when painting your truck bed in a low atmospheric condition or when you need quick drying/curing time.

The accelerator should be added to Durabak truck bed liner at the ratio of 1 can for every gallon of paint. 

Stir the mixture thoroughly for complete blending. The Accelerator won’t affect the performance of the Durabak coating. 

Etching Primer 

For some metals, you may need to apply a primer before painting. Consult our Durabak representative or product manual for this. 

METCOTE is a quick-drying, anti-corrosion, heat-resistant etch primer used on steel, iron, fiberglass, aluminum, concrete, galvanized metal, and other porous surfaces. 

Besides its excellent adhesion to various types of metal, the primer offers good resistance to water, acid, and alkali. It's also non-flammable and dries in 30 minutes at 77°F.

Zinc Phosphate Primer Spray 

Just like galvanizing, Zinc Phosphate Primer Spray seals metal to treat rust. This allows Durabak to form a strong bond with the metal, increasing durability. 

Rust Converter 

This formula converts rust chemically into an inert, black barrier on iron or steel surfaces, preventing further rusting. 

Apply Rust Converter with a sponge or paintbrush to function as a primer. 

Aluminum Oxide Sandpaper Sheet 

Use sandpaper sheet to etch the metal, fiberglass, or wood surface before applying the Durabak truck bed coating. Choose from a range of grit, including 40, 60, 80, and 100 grit.

    Used on my dump trailer bed

    I bought a used single axle dump trailer and the original paint was powder coat--which is a terrible paint for a trailer bed that gets scratched. Once the power coat is scratched the water gets under it and it continues to "pop" off the metal (had several places from dinner plate size to silver dollar size that were rusting). I cleaned and prepped the affected area per the instructions on this website, sanded then cleaned with Xzlene and applied the Durabak--3 coats to the inside of the bed, 2 to the outside. I can tell, this coating is going to be much better than what was in there from the factory. Yes, certain materials may stick a little more than the powder coat--but that's a small price to pay in my book for having a totally protected bed. I brush/rolled mine on and it was very easy to do.

    I recommend wearing a pair of disposable gloves during the process--Durabak won't come off your skin very well--you might even consider a pair of those throw away protective coveralls from the big box stores or a paint store.

    As with most things, it's 80% prep, 20% actual application. Take your time, read all the instructions, follow all the recommendations and you won't be disappointed. This stuff is TOUGH!!

    The only other warning is this stuff STINKS when it's drying. I had to let the last coat dry in my attached garage due to impending rainfall and it really puts off a strong odor--so be aware of that.
