How many coats are required for spray on truck bed liners?
I want to spray my truck bed with Spray Lining and Coatings bedliner. How many coats are required, and how long do I have to wait between coats?
The specific product being applied, consistency, and thickness required determine the number of coats needed. Our products can be applied at any given thickness depending on the application required. Most of our General Application products can be thickened with our Poly Powder, so you can spray a much thicker coat than with the liquids alone. Our coatings aren’t like products such as Raptor, which can only be applied at about 10 mil per coat. These coatings are 100% solids, and don’t skim over (preventing the coating from curing properly). This means you can spray as thick as you like, as long as it doesn’t start dripping.
In general, plan on one thick coat on the horizontals and 2 to 3 coats on the verticals. The extra coats don’t require full cure. You can apply a second or third coat once the product is set. Once the previous coat is thumbprint tacky (soft and tacky, but not coming off on your finger when touched lightly), additional coats can be applied. This is usually about 1 to 2 hours at 75 degrees.
Our fast curing polyurea products are sprayed in one continuous coat. They cure so quickly that there is no wait time involved. These products include not only our high or low pressure polyureas, but our RLA Cartridge Polyurea Bedliner as well.
