Zinsser Dryfall is a high-hiding interior acrylic coating for use over prepared ceilings and walls of commercial and industrial buildings. It is designed to provide a uniform finish on a variety of industrial construction materials with minimum amounts of overspray. Overspray quickly dries to a dust-like finish for quick and easy cleanup. Zinsser Dryfall may be used as a finish coat or a primer for use with a latex or solvent based topcoat.
