When applying TotalBoat Gelcoat, a gallon can cover approximately 12.8 square feet at 1/8" thickness, 25.7 square feet at 1/16" thickness, and 51.3 square feet at 1/32" thickness. For a quart of TotalBoat Gelcoat, expect around 1/4 of the coverage compared to a gallon at the same thickness.

It's important to note that the coverage estimates do not consider potential waste on brushes, tools, or in the container, so a 10% reduction in coverage is typical due to waste. The addition of solvents or thinners will not enhance coverage. The difference in coverage between gelcoat with or without wax is minimal.
