Applying a truck bed liner by spray gun is generally the established best practice. Truck bed liners are being sprayed at auto body shops all over america, and generally never rolled on except when DIY kits from many retailers are being used. The reason you see these trucks being sprayed and not rolled on is that the formula being used is designed to react and dry quickly so that the vehicles can be returned to service. In essence, fast dry time is a property that can be associated with a 2 part sprayed product versus a one part roll on.
Spraying is better for not only rapid cure time using a 2 part product, but also material final results control. With a brush or roller you cannot achieve the exact build and texture that you can with a spray gun. You can also reduce the time in-between coats if using our 100% solids products. When using ANY single part product, you must wait until the first coat is almost or completely dried before adding additional coats. Our products cure rather than dry, so the second coat can be applied by spray gun if needed while the initial coat is still soft.
Types of spray guns for coating application of most DIY products:
- Gravity Fed Hopper – quite a bit of control, 2 tips or one tip, premix material little control over set time
- Schutz Guns – Very little control, basic 2 step operation
- HV/HP Paint Gun – Used for top coating only
- Cartridge Spray Gun – Used for entry level professional application of our pure polyurea products
In summary, there are two major benefits to applying your truck bed liner with a spray gun versus rolling it on:
- The roller gives you less control over texture and most importantly, high build on vertical surfaces
- A material sprayed through a gun typically has a lower set time than cheap coatings that are designed to ONLY be rolled on.
