20% Solids Water-Based Penetrating Silane Sealer

SpecSilane 20 WB is a 20% solids, 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, providing excellent resistance to moisture and salt.

  • Provides excellent chloride screening.
  • Enhances water repellency while maintaining breathability.
  • VOC compliant with a low environmental impact, actual VOC = 20 g/l.
  • Reduces the effects of freeze-thaw cycling and weathering on concrete structures.
  • Offers long-lasting protection for new and existing concrete surfaces.
  • Dries tack-free and skid-resistant, preserving the natural appearance of the substrate without yellowing.

Application

SpecSilane 20 WB is used to protect concrete and masonry surfaces such as decks, pavements, parking structures, ramps, bridges, and marine platforms against corrosive effects from de-icing salts, moisture, and weathering to prevent spalling and deterioration.

New Concrete

  • Surfaces should be well cured (minimum 28 days).
  • Ensure the surface is free from curing residue, dust, debris, oil, and other contaminants.
  • The concrete must be absorptive to allow proper penetration of the sealer.

Old Concrete and Masonry

  • Remove any previously applied sealers and surface contaminants with pressure washing andSpecChem Citrus Cleaner.
  • Verify the substrate is absorptive for effective sealer penetration.
