The full cure time for TotalBoat TotalBilge epoxy bilge paint is 3-7 days, depending on a number of factors that can influence the paint's dry time, including wet film thickness per coat, ambient temperature & humidity, air flow (or lack thereof), whether or not the paint was thinned, and whether you applied the paint in the sun or shade. Warmer temperatures, with better air flow and lower humidity, will generally help an air-dry paint like TotalBilge cure faster than cool, damp conditions where there is vey little air movement.
