SpecShield SB Green Conscious Product

Silane-Siloxane solvent-based penetrating water repellent

SpecShield SB is a top-quality, 100% reactive, solvent-based silane-siloxane sealer designed to provide clear, penetrating, breathable water repellency for interior and exterior, above-grade concrete or masonry surfaces. By bonding directly with the substrate, it ensures excellent resistance to moisture and salt damage, making it an ideal solution for decks, pavements, parking structures, ramps, bridges, and marine platforms. This product is specifically formulated to combat the corrosive effects of de-icing salts, moisture, and weathering, thereby preventing spalling and the deterioration of concrete structures.

  • Offers excellent protection against chloride penetration.
  • Maintains excellent water repellency while allowing surfaces to breathe.
  • Compliant with VOC regulations (735 grams/liter).
  • Reduces damage from freeze-thaw cycles and environmental weathering on both vertical and horizontal concrete structures.
  • Provides long-lasting protection for new and existing concrete surfaces.
  • Quick-drying formula that leaves a tack-free, skid-resistant surface.
  • The clear, colorless solution that does not yellow over time.

Application

SpecShield SB is perfect for protecting a wide array of concrete and masonry surfaces against environmental elements that lead to damage and wear. Its application extends to commercial and industrial environments, including but not limited to decks, pavements, parking lots, and marine infrastructures.

Application Instructions: Application via a low-pressure, non-atomizing sprayer is recommended for best results. Coverage rates vary based on surface porosity, with a general guideline provided for different finishes. It’s essential that new concrete surfaces are dry and well-cured (minimum 14 days) before application. The substrate must be clean, free from moisture, and other contaminants to ensure effective penetration. Always test a small area first to confirm the desired outcome.

Packaging

Available in 55-gallon drums and 5-gallon pails.
