A - In nearly all cases, a solvent-based product provides more protection per coat. This, of course, depends on the square foot coverage and the solids content of the product being applied. The dried measurement of each coat of finish applied, whether it be water or solvent-based, is determined by dividing the square foot coverage of the product being applied into 1,600, which equals wet mil thickness. One mil equals 1/1000 of an inch. This total is then multiplied by the solids content of the product.

Water-Based Example: Hillyard Tip-Off' is applied at approximately 700 sq. ft. per gallon and has a solids content of 32 percent. = 2.29 (wet mil thickness) X .32 = .733 dry mil thickness per coat

Solvent-Based Example: Hillyard 450 Gym Finish is applied at approximately 500 sq. ft. per gallon and has a solids content of 50 percent. 1600 ~ 500 = 3.2 (wet mil thickness) X .50 = 1.6 dry mil thickness per coat
