It is not recommended as a deck finish. Exterior 450 is fortified with UV absorbers to stabilize and protect the integrity the finish*, and built-in mildewcides to slow mold and mildew growth. It performs well as a clear coat or as an optional topcoat over darker colors General Finishes Milk Paint. Do not use over light or white paints, as yellowing may occur. *The UV additive in 450 Clear will protect the film's integrity, but will not prevent the wood from changing color from sunlight.
