40% Solids Water-Based Penetrating Silane Sealer

SpecSilane 40 WB is a 40% solids, 100% reactive waterborne silane sealer. This clear, penetrating, breathable water repellent is designed for use on interior and exterior above-grade concrete or masonry surfaces. It penetrates the surface and bonds directly with the substrate, resulting in a surface highly resistant to both moisture and salt.

  • Excellent Chloride Screen: Provides superb protection against chloride penetration.
  • Water Repellency: Enhances water repellency while maintaining the substrate’s breathability.
  • Eco-Friendly: VOC compliant and water-based, reducing environmental impact.
  • Durable: Offers long-lasting protection for new and existing concrete surfaces.
  • Non-Yellowing: Maintains the natural appearance of the substrate without discoloration.
  • Application Versatility: Suitable for decks, pavements, parking structures, ramps, bridges, and marine platforms.
