A waterborne acrylic product that protects interior and exterior masonry surfaces from corrosive liquids and weathering. As a sealer, it penetrates deep to seal and protect masonry against acids, alkalis, household cleaners, gasoline, oil, and salt. It also seals against dusting and retards spalling, surface cracking, and pockmarking. As a primer, it is an ideal undercoat for latex paints. It primes chalking masonry paint, porous asbestos siding, sandblasted masonry, and powdering mortar. Follow surface preparation as per label instructions. Prevents moisture damage when applied to brick, terrazzo, slate, concrete, and other masonry surfaces. Use on driveways, garage floors, basement walls and floors, sidewalks, and above ground foundations. Allow 6 hours drying time before subjecting to light foot traffic and 24 hours for heavy traffic. Covers approximately 400 sq. ft. per gallon. Clean tools with soap and water.
