SEAL-ONCE combines proprietary penetrating nanotechnology with the strength of polyurethane to provide 360° of protection. NANO+POLY penetrates deep-down, 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 efflorescence, 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 UV fading, 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 and decay. NANO+POLY is a water based, Low VOC, non-toxic, Eco-safe sealer that will not harm pets, plants or people. NANO+POLY concrete goes on milky white and dries clear. Protects up to 10 years on vertical surfaces & 6 years on horizontal
