SpecShield WB 
Silane-siloxane water-based penetrating sealer
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 concrete block. SpecShield WB 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 helps protect concrete and concrete block, 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
SpecShield WB is designed to enhance the longevity of concrete and concrete block structures such as decks, pavements, parking structures, ramps, bridges, and marine platforms by offering exceptional protection against de-icing salts, moisture, and weathering.
Application Instructions: For optimal results, use a low-pressure, non-atomizing sprayer for application. Coverage varies based on surface porosity. New concrete surfaces must be dry and well-cured (minimum 14 days) and free from moisture, curing residues, and contaminants. Always perform a test area to ensure satisfactory results.
Packaging
Available in 55-gallon drums and 5-gallon pails.
