Protect your masonry from water damage with Stormdry Masonry Protection Cream, a BBA-certified silicone cream offering long-lasting water repellency. Applied in a single coat, this breathable, colourless finish penetrates deep into porous substrates like brick, mortar, sandstone, and concrete, creating a barrier that resists rain while allowing moisture vapor to escape. This significantly improves energy efficiency by reducing heat loss through damp walls. Stormdry is designed to last over 25 years, self-sealing minor cracks up to 0.3 mm. It maintains the natural appearance of the wall and is ideal for protecting cavity wall insulation. The cream appears white upon application but fades as it absorbs, with surfaces becoming shower-resistant within 2-4 hours. Protects brick, stone, mortar, sandstone, and granite. Keeps walls dry and warm. Features independent BBA approval (Certificate Number: 15/5198). Product Summary: Stormdry Masonry Cream, BBA certified, silicone-based, deep penetration, water repellent, breathable, colourless finish, 25-year lifespan, suitable for brick, mortar, sandstone, concrete, protects insulation, improves energy efficiency, easy application.
