Below are estimates for the amount bottom paint you will need to properly cover your boat. Actual square footage and coverage may vary by boat and bottom paint. Please review the specific products specifications on each product page on our site.
Most ablative / self polishing bottom paints require 2 coats since they are designed to wear away over time. More is better than not enough bottom paint! Most hard modified epoxy bottom paints will require just one good coat (just don’t miss any areas!)
Length of Boat (Feet) |

| 20-25 | 3 Quarts | 1 Gallon + 2 Quarts |
| 25-30 | 1 Gallon | 2 Gallons |
| 30-32 | 1 Gallon + 1 Quart | 2 Gallons + 2 Quarts |
| 33-37 | 1 Gallon + 2 Quarts | 3 Gallons |
| 38-40 | 1 Gallon + 3 Quarts | 3 Gallons + 2 Quarts |
| 41-42 | 2 Gallons | 4 Gallons |
| 43-44 | 2 Gallons + 1 Quart | 4 Gallons + 2 Quarts |
| 45-46 | 2 Gallons + 2 Quarts | 5 Gallons |
| 47-49 | 2 Gallons + 3 Quarts | 5 Gallons + 2 Quarts |
| 50-52 | 3 Gallons | 6 Gallons |
| 53-55 | 3 Gallons + 1 Quart | 6 Gallons + 2 Quarts |
| 56-59 | 3 Gallons + 2 Quarts | 7 Gallons |
| 60-61 | 4 Gallons | 8 Gallons |
| 62-63 | 4 Gallons + 2 Quarts | 9 Gallons |
| 64-65 | 5 Gallons | 10 Gallons |

Swimming Pool Paint Theoretical Coverage: Length x Width X 1.7 x 2. Divide this number by 500 to get the total number of 2 gallon kits needed, or divide by 300 to get the total number of gallons needed.
See Our Article -> How to Determine How Much Pool Paint You Need
Gel Coat 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 ft. 1 Gallon = Approximately 48 square ft.

AwlGrip Topside – 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.
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.
Re-coatability: 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.
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.
AwlCraft 2000 – 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.
Re-coatability: Spray applications consist of 2-3 coats applied over 1-4 hours. Exact time will vary with temperature, project size, and film thickness applied.
