Once cooled, you can pour the next layer without additional surface prep all the way up until you can no longer indent a fingernail into the previous coat.

The time quoted on packaging is not necessary the actual cure time. Always apply a seal coat before flood coating. That being said, you shouldn’t have any issues overcoating a urethane coating. ![]() Scratch repair can be accomplished in two ways. You can decrease the amount of mica to create a translucent effect or use a couple drops of alcohol ink to create tint. Warm soapy water works well for hardeners.
