Web5.2 All procedures involve taking measurements of applied coating powders in the pre-cured, pre-gelled state to help insure correct cured film thickness. This enables the application system to be set up and fine-tuned prior to the curing process. In turn, this will reduce the amount of scrap and over-spray. WebMar 13, 2024 · Not enough mils – For best results, apply the gelcoat to a wet film thickness of 25 mils. This will result in a cured film thickness of 18-22 mils. As gelcoat cures, it gives off heat in an exothermic chemical reaction. If the gelcoat is applied to thin, it will not reach the temperature needed and will not cure fully.
