![]() Temperature Ideal temperature of the surface (substrate), air, and coating material should be between 50-90☏.In general, ideal conditions for applying bottom paint include the following: The same applies if you remove the boat from the water during the season, and keep the boat out of the water longer than two weeks.īefore applying antifouling paint, always check the paint manufacturer's temperature/relative humidity (RH) specifications on the label or technical data sheet for best results. If this window is exceeded, you need to scuff the bottom lightly with a Scotch-Brite pad to reactivate the antifouling properties before splashing the boat. Other ablative antifouling paints must be launched within a two-week window after bottom painting. If launched within this generous window, the paint requires no scuffing to activate the self-polishing properties before splashing the boat. SPC (self-polishing copolymer) ablative paints such as TotalBoat Spartan are water-activated and can be painted up to 18 months prior to launch. Paint at the end of the season, then you don't have to repaint or scuff the surface before splashing. The timing of bottom painting also depends on the type of antifouling paint because some paints allow you to wait longer between painting and splashing the boat. For best results, a little planning and patience are needed since there's nothing you can do about the weather, especially when painting outside. And the right day is when the temperature, dew point, and relative humidity are at acceptable levels. The right time of year is when you haul the boat out at the end of the season. ![]() Longer-lasting, more effective paint jobs come to those who waitįor the right time to paint, that is.
