Product Description
Siloxane WB Concentrate is a water-based, high-performance water repellent concentrate that dilutes with fresh water on site. Designed for vertical or horizontal application, it provides deep penetration and long-lasting protection against water-related staining or deterioration. It chemically bonds within the masonry to form a vapor-permeable barrier.
