Zinsser Odorless Oil-based Interior Stain Blocker, White, 1 Gal.

Use for priming and sealing new or previously painted interior drywall, plaster, paneling, wood, stucco, and metal. Seals porous surfaces so less topcoat paint is needed. Its high-adhesion formula allows painting on glossy surfaces as well as textured or acoustic tile ceilings. Sands easily, making it a great enamel undercoater for doors, cabinets, trim, and paneling. Effective stainkiller blocks water stains, nicotine, crayon, marker, tannin, and graffiti. Bright white, non-yellowing, can be left unpainted. Covers 350 to 400 Sq. Ft. per gallon on nonporous surface.
