SpecChem SpecShield EX

Silane-Siloxane Exempt Solvent Penetrating Water Repellent

SpecShield EX is a 100% reactive, exempt solvent silane-siloxane sealer. This clear, penetrating, breathable water repellent is designed for use on both horizontal and vertical, interior and exterior, above-grade concrete or masonry surfaces. It penetrates the surface and bonds directly with the substrate, providing a surface highly resistant to moisture and salt attack.

  • Provides excellent chloride screen.
  • Offers excellent water repellency while maintaining breathability.
  • VOC content 350 grams/liter, OTC, LADCO compliant.
  • Reduces the effects of freeze-thaw cycling and weathering on concrete structures.
  • Long-lasting protection for both new and existing concrete surfaces.
  • Dries quickly, tack-free, and skid-resistant.
  • Colorless and non-yellowing, preserving the natural appearance of the substrate.
