Sanding Sealer is a water base acrylic basecoat. It provides initial sealing for all GF water base topcoats and can be used over raw wood or a stained surface.
Sanding Sealer has been sterated so it will sand easier. Sanding Sealer is not as durable as the topcoats so it is not recommended for a final finish. Drying Time: 1-2 hours under normal conditions. (70°F -70% humidity)
