5 GAL NANO + POLY Concrete & Masonry Sealer

5 Gallon SEAL-ONCE NANO+POLY Concrete & Masonry Sealer combines proprietary nanotechnology with the strength of polyurethane to provide 360° of protection. NANO+POLY penetrates below the surface to protect against water damage from the inside-out. It forms a long-lasting water resistant shield within the capillaries of concrete and masonry, preventing effluorescence, cracking, spalling, mold and mildew growth, lime bloom and freeze/thaw damage. In addition to penetrating to coat the pores of the concrete, NANO+POLY creates a durable surface coating that protects against wear and tear, and water damage. It creates a UV-stable, non-yellowing coating that preserves the natural color of the concrete and resists weathering & decay. NANO+POLY is a water based, non-toxic, eco-friendly sealer that will not harm pets, plants or people. It goes on milky white, dries clear and cleans up with soap & water. It is a great investment to protect and extend the useful life of your concrete walkways, patio, pool deck, stamped concrete, bricks, or pavers. Not recommended for concrete driveways or garage floors.
