FOSROC Nitocote SN522

SN522 is a high-performance, single-component, penetrating silane-siloxane water repellent. 

Specially formulated to penetrate deeply into porous substrates such as concrete, brickwork, and masonry, Nitocote SN522 chemically reacts within the substrate to form a durable, bonded, water-repellent lining. This treatment significantly reduces water and salt absorption while allowing water vapor to escape, ensuring long-lasting protection without altering the appearance of the surface

Technical Specifications

Type: Single-component, penetrating silane-siloxane water repellent Appearance: Clear liquid Application: Brush, roll, or spray onto clean, dry surfaces Substrate Compatibility: Concrete, brickwork, masonry, and other porous mineral surfaces Coverage: Varies with substrate porosity; refer to manufacturer’s guidelines Water Vapor Permeability: Allows substrate to breathe while repelling liquid water Packaging: Commonly available in 20-liter containers Storage: Store in a cool, dry place away from direct sunlight

Benefits and Advantages

Superior Water Repellency: Forms a bonded, non-staining water-repellent lining within the substrate, protecting against rain, moisture ingress, and water-borne salts.Deep Penetration: Effectively penetrates porous surfaces for long-lasting protection. Breathable Protection: Allows water vapor to escape, preventing trapped moisture and associated damage. Non-Staining: Does not alter the appearance or color of treated surfaces. Easy Application: Supplied as a ready-to-use, single-component liquid for hassle-free application. Reduces Maintenance: Minimizes efflorescence, surface deterioration, and maintenance costs.
