Sure Klean® Weather Seal Siloxane WB concentrate is a self-emulsifying water repellent concentrate designed for dilution with fresh water at the jobsite. This solvent-free blend of silanes and oligomeric alkoxysiloxanes mixes easily with water to produce a penetrating water repellent ideal for application to dense or porous masonry surfaces. Weather Seal Siloxane WB can also be used as a primer to even out porosity and improve adhesion of BMC® Breathable Masonry Coatings. Weather Seal Siloxane WB complies with all known regulations limiting Volatile Organic Compound (VOC) content. An effective alternative to conventional solvent-based silanes or siloxanes, Weather Seal Siloxane WB penetrates and chemically bonds deep within the masonry substrate to provide long-lasting protection against water-related staining or deterioration. Will not darken, produce a surface film or impair the natural breathing characteristics of treated surfaces


  • Ideal for field or in-plant treatment of concrete or GFRC
  • Easy soap-and-water cleanup from window glass, window frames and application equipment
  • Alkaline stable suitable for new green concrete
  • Low odor reduces risk of application to occupied buildings
  • Penetrates deeply to produce long-lasting protection on vertical or horizontal surfaces
  • Water based formula minimizes explosion and fire hazards associated with alcohol or solvent- based water repellents
