About This Product


Sure Klean Weather Seal Natural Stone Treatment WB Plus is a water-based water repellent for limestone, marble and travertine that delivers the same performance as solvent-based products, without the drawbacks of traditional water-based treatments. VOC-compliant, ready-to-use, and low odor, this modified siloxane water repellent was developed to provide long-lasting penetrating protection.

Compared to conventional water-based water repellents for limestone, marble and travertine, Weather Seal Natural Stone Treatment WB Plus has greater water-repellency, longer service-life and is less likely to stain. Use of this product will not alter the substrate’s natural texture but may cause some darkening. Always test to ensure desired results before overall application.

  • Provides water repellency to limestone, marble and travertine, as well as adjacent masonry.
  • One component – easy-to-use.
  • Treated surfaces “breathe” – does not trap moisture.
  • Suitable for interior and exterior surfaces.
  • Will not form a surface film or gloss.
  • It does not change the substrate’s texture. Always test to ensure desired results before the overall application.
  • Protects new or existing mortar and grout joints.
  • No solvent odor.
  • Eligible for an extended warranty.

Note: Please check the VOC Compliance chart under the Documents tab to see if this product is compliant in your area.
