What coating application rate is specified?

Explanation:
Coating application rate is set as a target amount of coating per unit area with a tolerance to allow for field variability. The specified value is 40 ± 10 gal/yd², meaning the coating should be applied so that the coverage falls between 30 and 50 gal per square yard. This range ensures the intended film thickness and protective performance while accounting for differences in substrate absorption, surface texture, and application technique. Applying significantly less or more could compromise adhesion or durability, so the 40 ± 10 gal/yd² window is used as the standard.
