| USEFUL FACTS |
| 8 fl. Oz. = 1 cup |
| 2 cups = 1 pint |
| 4 quarts = 1 gallon |
| 1 sq. foot = 144 sq. in. |
| 1 sq. yard = 1,296 sq. in. |
| 1 gallon = 231 cu. In. |
| 1 cubic foot = 1,728 cu. In |
| 1 cubic yard = 46,656 cu. In. |
| 1 cubic yard = 27 cu. Ft. |
ESTIMATING FORMULA:
(1600 sq. ft. per gal./Dry Mil Thickness) x Solids Content
= Application Rate per Gallon
100% SOLIDS COATING APPLIED AT 10 DRY MILS:
(1600 s.f. per gal./10 dry mils) x 100% solids (or 1)
= 160 s.f. per gal.
50% SOLIDS COATING APPLIED AT 10 DRY MILS:
(1600 s.f. per gal./10 dry mils) x 50% solids (or .5)
= 80 s.f. per gal.
