    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.

    You can never go wrong with Durabak truck bed liner. Durabak comes in different truck bed liner colors to suit every taste and need.

Durabak 18 Marine Liner Outdoor (Smooth)

We had been ordering the textured for a local first responder for a few years, before going with the smooth this year. They report application was much easier, and the feel is just what they hoped.

houseboat roof and decks

I used 4 gallons of Durabak marine to recoat the roof and front and rear decks of a 35x10 houseboat. I started with 2 gallons of textured for a single layer coat followed up with a coat of smooth. I can't believe how hard the coating is. I had to reattach railings and other items I had taken off to paint. Drilling through the coating I had to 2nd guess if I was in the right spot. My only complaint is that the textured is too rough on my bare feet. I definitely won't worry about slipping. If I was doing it again I would do 1 gallon of textured to 3 gallons of smooth. I assume some of the roughness will wear in with time and if in several years I need to do another coat I will just re-coat with smooth. Only been on the boat for 2 months but I like what I see so far.

Good Product

The marine coating went on easily and seams to be very durable.

The floor of my boat looks amazing.
