Exterior —

Create a super tough, weather-resistant surface for your outdoor (and indoor) foam projects. Exterior Foam Coat is not sandable. It has a rough stone feel when dry. Trowel it smooth, or brush it to make a super rough finish. This formula sets in a few hours, but takes 5 days to fully cure.
