Table values were computed from the following formula (1604 = A 100% volume solids product applied at 1 mil)

1604 x volume solids (VS) / dry film thickeness (DFT) in mils Example: 1604 x 35% (VS) = 561 / 2 mils DFT = 281 ft2/gal

Relationship of WFT (Wet Film Thickness) to DFT (Dry Film Thickness)

(unthinned and thinned)

How to calculate WFT to DFT (unthinned) WFT x volume solids = DFT

Example: 8 mils WFT x 35% volume solids = 2.8 mils DFT

How to calculate WFT to DFT (thinned 10%) WFT x (volume solids / 1 + % thinner by volume) = DFT

Example: 8 mils WFT x (35% (VS) / 110% = 32% (VS)) = 2.5 mils DFT

How to calculate DFT to WFT (unthinned) DFT / volume solids = WFT

Example: 2.8 mils DFT / 35% volume solids = 8 mils WFT

How to calculate DFT to WFT (thinned 10%) DFT x (1 + % thinner by volume) / volume solids = WFT

Example: DFT x110% = 3.08 / 35% volume solids = 8.8 mils WFT

Cost per mil sq. ft. @ $14.50 per gallon

1604 x 35% volume solids = 561 sq. ft. per gal @ 1 mil

$14.50 per gal / 561 = $0.02584 per sq. ft. at 1 mil

Cost calculated @ 2 mil recommended DFT 1604 x 35% = 561 sq. ft. / 2 mils = 281 sq. ft. per gal

$14.50 per gal / 281 = $0.05160 per sq. ft.
