Al’s Liner DIY Truck Bed Liners

Below is a list of items you will need to apply your Al’s Liner DIY Truck Bed Liner Kit. Many of these are items you might find in your garage already. If you’re missing something, look for a link to the Al’s Accessories page – whatever you need to get the job done, Al’s Liner has you covered.


Personal Protection

You must wear personal protection when mixing and spraying Al’s Liner DIY Truck Bed Liner Kits. The recommended respirator to use is a dual cartridge chemical respirator. Al’s does not release MDI during the spray process so supplied air respiration is not required and you do not have to have a spray booth. We do recommend wearing disposable painter’s suits as there will be over spray. Also recommended are latex or rubber gloves for protection of your hands and appropriate eye protection during the mix and application processes.


Masking Materials

You can use a variety of materials to mask the area you do not want sprayed. You can use materials such as paper or plastic. We recommend using plastic. Al’s Liner is a heavy material on paper and can cause problems when removing the paper masking. Plastic carries the weight better to prevent tearing during the unmasking process.



You will want to use a good automotive grade masking tape to determine your spray lines. Al’s gives you approximately a 45 minute window to remove the masking and still get a nice crisp, clean line. You do not need wire tape. You will want to pull the tape line at a 45 degree angle back over the sprayed area to get a clean crisp edge.


Sand Paper or Abrasion Tools

You will want to scratch and scuff the area to be sprayed using a 180 grit or more aggressive abrasive. You can use sand paper, cup brushes, needle scaler, etc. You just need to make sure the entire area is thoroughly scratched and cleaned well before priming.

Solvents and Cleaners

You will want a good quality pre-paint cleaner to wipe down the spray area after scratching and scuffing the surface. You need to insure any debris and residue is removed prior to priming the area and applying Al’s Liner. You can also use solvents such as denatured alcohol or lacquer thinner to clean up any spillage or mishaps.


Air Compressor

If you are spraying Al’s Liner DIY Truck Bed Liner Kits, you will need an air compressor. You need a minimum of 7 cfm capacity and 25 psi at the gun. This is the recommendation for the Al’s Liner Spray Gun. Keep in mind that you do not want to exceed 55 psi at the gun. This will generate too much over spray which wastes material. You can achieve virtually any texture from 25 to 55 psi.


Mold Release

You will want to treat your Al’s Liner Spray Gun with a mold release prior to pouring the liner in. This will allow for easy cleanup. You can also use Vaseline to coat the interior of the gun to help facilitate cleaning. If you do not use mold release or Vaseline prior to use, you should flush the gun immediately after application with denatured alcohol or lacquer thinner.
