Wacker Water Repellent BS3003

Wacker BS3003 Water Repellent is a high-performance, silane-siloxane based water repellent solution developed to protect mineral building surfaces from moisture penetration. It is designed to deeply penetrate porous substrates and create a hydrophobic barrier while allowing the surface to remain breathable.

This water repellent is supplied as a ready-to-use clear liquid and is widely used on exterior building surfaces where long-term protection against water absorption is required. Wacker BS3003 provides excellent water repellency on concrete, brickwork, natural stone, cement plaster, and masonry surfaces, helping to reduce water ingress, dampness, and weather-related damage without altering the natural appearance of the surface.

Wacker BS3003 Water Repellent is formulated to offer durable performance under exterior exposure. After application, it significantly reduces water absorption while maintaining vapour permeability, allowing trapped moisture to escape. This helps improve the longevity of building façades and reduces issues such as efflorescence, staining, and surface deterioration caused by moisture.
