B-Water Block Protective Water Repellent – 1 Litre

Bellinzoni B-Water Block Protective Water Repellent – 1 Litre

Bellinzoni B-Water Block Protective Water Repellent is a water-based treatment designed to protect natural stone and masonry surfaces from water penetration and weather-related deterioration. Recommended for marble, granite, natural stone, terracotta, architectural bricks and concrete, it helps create a water-repellent bead effect while maintaining the original appearance of the treated material. Its penetrating formulation works within the substrate rather than forming a visible surface coating, allowing treated surfaces to remain breathable. The product is described as UV-resistant and non-yellowing, helping preserve the appearance of exterior and interior surfaces over time.

Its hydrophobic properties also help reduce water absorption and protect against damage associated with mildew, mould, efflorescence and freeze-thaw conditions. Suitable for indoor and outdoor use, B-Water Block can be applied to clean, dry surfaces using a brush, roller or low-pressure spray. Allow the product to dry completely for 6–8 hours, with full protection developing after 24 hours, according to the product instructions.
