Fosroc Nitocote SN 522 — water repellent coating for concrete & masonry (20 L)

Fosroc Nitocote SN 522 is a premium water repellent coating from Fosroc Chemicals India Pvt. Ltd. — a silane-siloxane based, solvent-borne surface treatment engineered to provide deep-penetrating, invisible water repellency to concrete, masonry, brick, and natural stone surfaces.

Unlike film-forming waterproof coatings, Nitocote SN 522 penetrates into the substrate to chemically react with the pore structure — creating a durable hydrophobic lining that repels water and chloride ions while allowing the surface to breathe naturally. This makes it an ideal waterproofing chemical for exterior walls, facades, bridges, columns, parapets, and exposed concrete structures requiring long-term protection against driving rain, moisture ingress, carbonation, and chloride-induced corrosion of reinforcement steel.

Backed by Fosroc — a globally trusted name in construction chemicals — Nitocote SN 522 ensures strong reliability, user-friendly application, and consistent on-site performance. A dependable water repellent coating solution preferred by applicators and contractors across India for its proven long-term durability and effectiveness in protecting structural concrete and masonry surfaces.
