Product Information

Weather Seal Silox WB Concentrate is a Long-lasting high-performance water repellent.

Sure Klean Weather Seal Siloxane WB Concentrate is a concentrated water repellent designed for dilution with fresh water at the job site. 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.

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.


  • Treated surfaces “breathe” – does not trap moisture.
  • Concentrate minimizes storage, transport and container disposal requirements.
  • Mix with up to 19 parts fresh water. One gallon concentrate treats up to 4,000 square feet. Consult coverage rates.
  • Alkaline stable – suitable for new concrete.
  • Penetrates deeply – effective on vertical or horizontal surfaces.
  • Ideal for field or in-plant treatment of precast concrete.
