I’m trying to figure out how much spray on bed liner I need for my truck. Can you provide some recommendations on how much bedliner I need?
Since an average truck bed = 70 square ft., and a good liner is not required to be same thickness throughout (some areas less subject to damage than others), it follows that high stress areas > 100 mil and low stress areas < 50 mil. Therefor, 3 gallons are required for an average truck bed with no waste. We recommend considering waste, the actual size of your truck bed, and the intended purpose of your bedliner when ordering any spray in coating.
We have an online bedliner coverage calculator available as well. You can simply put in the measurements, and click whether or not you are covering the walls and/or rails. This will break it down into surface area for the sides, back, and front in addition to the floor area. Then select the average mil thickness, and you will find out how many gallons you need if using our 100% solids products.
Remember… For coatings such as Raptor, etc., you have to divide the total number of gallons by the % solids (by volume) of the particular coating. For instance, Raptor is 57% solids, so you divide by .57. In this example, if you need 3 gallons of our product, you need 5.26 gallons of Raptor (3 / .57 = 5.26). Of course… Raptor and many others don’t recommend more than 3 coats of their products, so you really can’t apply a coating more than 20 mils anyway.
