Prosoco Siloxane WB Concentrate

Siloxane WB Concentrate mixes easily with fresh water on the job site to produce a penetrating water repellent ideal for application to dense or porous masonry surfaces. An effective alternative to conventional solvent-based silanes or siloxanes, Siloxane WB penetrates and chemically bonds deep within the masonry substrate to provide long-lasting protection against water-related staining or deterioration.
