SEAL-ONCE NANO+POLY Concrete & Masonry Sealer, 5 Gallon - Outdoor Use

SEAL-ONCE NANO+POLY Concrete & Masonry Sealer is a cutting-edge, water-based solution that deeply penetrates and protects your outdoor concrete and masonry surfaces. Its advanced blend of nanotechnology and polyurethane forms a flexible, breathable barrier inside the pores of the material, defending against water intrusion, freeze/thaw cycles, efflorescence, mold, mildew, cracking, and spalling. The clear, UV-stable formula preserves the natural look of your concrete or masonry and resists yellowing, peeling, and weathering through years of exposure. This ultra-low VOC, non-toxic sealer is safe for people, pets, and plants, and is easy to apply by brush or sprayer, with quick soap-and-water clean-up for hassle-free maintenance. Ideal for patios, pavers, pool decks, brick, and vertical or horizontal concrete, NANO+POLY Concrete & Masonry Sealer is the go-to eco-friendly solution for long-lasting outdoor surface protection.
