Sure Klean Weather Seal Siloxane PD

Brand Prosoco
Material Masonry Sealant

Sure Klean® Weather Seal Siloxane PD (predilute) is a ready-to- use, water-based silane/siloxane water repellent for concrete and most masonry and stucco surfaces. Siloxane PD will not impair the natural breathing characteristics of treated surfaces. It helps masonry resist cracking, spalling, staining and other damage related to water intrusion. Low odor and alkaline stable, Siloxane PD is ideal for field and in-plant application.

  • Penetrates deeply for long-lasting protection on vertical or horizontal surfaces.
  • Service life is estimated at more than 10 years.
  • Treated surfaces “breathe” – does not trap moisture.
  • Water-based formula minimizes explosion and fire hazards compared to solvent-based water repellents.
  • Appropriate for use on manufactured stone surfaces.
  • Resists water penetration when applied over existing shrinkage cracks of 0.02 inches or less.
