SpecShield WB Extra

High solids silane-siloxane water-based penetrating sealer

SpecShield WB EXTRA is a 100% reactive, waterborne silane-siloxane sealer. This clear, penetrating, breathable water repellent is designed for use on horizontal/vertical, interior/exterior, above grade concrete or masonry surfaces. SpecShield WB EXTRA penetrates the surface and bonds directly with the substrate, which results in a surface that is highly resistant to both moisture and salt attack. SpecShield WB EXTRA helps protect concrete and masonry surfaces, decks, pavements, parking structures, ramps, bridges, marine platforms etc. against the corrosive effects of de-icing salts, moisture and weathering to prevent spalling and deterioration of concrete structures.

  • Provides excellent chloride screen
  • Excellent water repellency while maintaining breathability
  • Actual VOC = 0 grams/liter
  • Reduces the effects of freeze-thaw cycling and weathering on vertical/horizontal concrete structures
  • Long-lasting protections for new as well as old concrete surfaces
  • Dries tack-free and skid-resistant
  • Water-based, colorless and non-yellowing

Application

  • Equipment: Use of a low pressure, non-atomizing sprayer is highly recommended.

Application Instructions

  • New concrete surfaces should be dry, well cured (minimum 14 days) and free of moisture, curing residue, dust, debris, oil, and contaminants to ensure effective penetration.
  • Apply generously using a low pressure sprayer and adjust the application rate on very porous surfaces. Follow a wet-on-wet method without allowing excess to dry on the surface.

Packaging

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

Shelf Life

  • Containers should be sealed and stored in a clean, dry area between 45-85°F. Shelf life is two years in unopened containers.

Coverage

  • Coverage Rate: Depends on surface porosity:
    • Extremely Porous surfaces: 100-125 ft²/gal
    • Broom finish: 150-200 ft²/gal
    • Smooth concrete: 200-350 ft²/gal

Test Data
