Question:

Most bed liners seem to be applied very thin. How thick is SL&C truck bedliner?

Answer:

Thickness of a Spray Lining and Coatings brand truck bed liner is completely dependent on the applicator. Our coatings are often twice the strength because they’re economically applied at twice the thickness of other brands. In addition, the strength specifications are as high as, or higher than many national brands.

You can apply our coatings at any thickness theoretically. Of course, any individual coat would drip at some point. With our powder additives, you will find that each coat can be applied much thicker than typical bed liner products. These products will also cure to same mil height as applied, since they are 100% solids. Many national brands are only 50% solids, and will be half as thick once dried.

For typical truck bed liner application, we usually recommend 45-mil (45/1000th inch) on the walls, and 63-mil on the base. This would require a couple of coats, if using our Poly Powder additives. If using just the liquids, you would probably require about 3 to 4 coats on the walls to avoid drips.

Notes on Thickness:

When comparing thickness of any product, divide 1604 by the desired mil height to get the square foot coverage per gallon when the coating is wet. Then multiply that by the % solids to get the coverage when dry. As an example: Spray Lining and Coatings bedliner at 40 mil would get 40 square feet per gallon (1604 / 40 = 40, and 40 X 100% = 40). With Raptor (57% solids), you would get 23 square feet at 40-mil (1604 / 40 = 40, and 40 X 57% = 28.8).

NOTE: Some products (such as Raptor) have limitations regarding how thick a single coat can be applied (12 mil for Raptor), and a limit on how many coats are recommended. In the case of Raptor, 3 coats max is recommended, so wet film thickness total can’t be over 36-mil, and cured thickness would be max of 20.5 (36 X 57% = 20.5).
