SpecShield EX Green Conscious Product

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.

Application

Preparation:

  • Ensure the surface is dry, well cured (minimum 14 days), and free from moisture, curing residue, dust, debris, oil, and other contaminants. Surfaces must be absorptive to allow penetration of SpecShield EX.

Application Method:

  • Apply using a low pressure, non-atomizing sprayer (10 to 20 psi), broom, or squeegee out any puddles or standing material immediately. Adjust application rate on very porous surfaces and follow a wet-on-wet method. Do not allow excess to dry on the surface.

Packaging

  • Available in 55 gallon drums and 5 gallon pails.
