*Above estimates only for bottom paint. Actual square footage and coverage may vary by boat and bottom paint.
Gel Coat Paint Theoretical Coverage: You should determine the square footage by multiplying the Length x Width of the surface that is going to be covered with gel coat. When you apply the recommended wet film of 18 mils you will get this coverage per coat:1 Quart = Approximately 12 square ft1 Gallon = Approximately 48 square ft.
AwlGrip Topside Paint Theoretical Coverage: Brush/Roller Application: 700-725 Sq. Feet at 1 mil (25 Microns) dry: 285 Sq. Feet at recommended dry film thickness.Recommended Wet Film Thickness: 4.5-6 mils (112.5-150 Microns), Total of 2 Coats.Recommended Dry Film Thickness:  2-3 mils (50-75 Microns), Total of 2 Coats.Recoatability: Spray applications consist of 2-3 coats applied over 1-4 hours. Exact time will vary with temperature, project size, and film thickness applied. Brush/Roller applications require at least 2 coats applied minimum of 16 hours apart. Awlgrip topcoats which have been allowed to dry more than 24 hours must be sanded before recoating.Spray Application:530 Sq. Feet at 1 mil (25 microns) dry film thickness; 210 SQ. Feet at recommended dry film thickness.Recommended Wet Film Thickness: 6-9 mils (150-225 Microns), Total of 2-3 Coats.

Recommended Dry Film Thickness:  2-3 mils (50-75 Microns), Total of 2-3 Coats.
Coverage calculations are calculated for mixed base and converter, reduced 25% and are based on a theoretical transfer of efficiency of 100%. Actual coverage rate obtained will vary according to equipment choice, application techniques, part size, and application environment.
Anticipated Cure Time at 77 F/ 50% R.H.: 24 hours to tape free, 3 days to light service, 14 days for full cure.
For AwlCraft 2000 Topside Paint Theoretical Coverage:
Spray Application: 573 Sq. Feet at 1 mil (25 microns) dry film thickness; 230 SQ. Feet at recommended dry film thickness.
Recommended Wet Film Thickness: 6-9 mils (150-225 Microns), Total of 2-3 Coats.
Recommended Dry Film Thickness:  2-3 mils (50-75 Microns), Total of 2-3 Coats.
