Durasilane WB is a premium water-based silane/siloxane water repellent designed to impregnate and protect absorbent mineral building surfaces. This solvent-free penetrating treatment reduces water absorption while allowing the substrate to remain breathable, helping prevent moisture-related deterioration without sealing pores or trapping vapour.
Ideal for bricks, sandstone, plaster, fibre cement, aerated concrete and façade surfaces, Durasilane WB is widely used to protect buildings against water ingress and as a water-repellent primer before decorative coatings. Its environmentally friendly formula offers deep penetration, rapid water repellency and excellent long-term substrate protection.
