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, and breathable water repellent is designed for use on both horizontal and vertical, interior and exterior, above-grade concrete or masonry surfaces. By penetrating the surface and bonding directly with the substrate, SpecShield WB EXTRA ensures a surface that is highly resistant to both moisture and salt attack.
Applications
- Protects concrete and masonry surfaces such as decks, pavements, parking structures, ramps, bridges, and marine platforms against the corrosive effects of de-icing salts, moisture, and weathering to prevent spalling and deterioration.
- Provides an excellent chloride screen.
- Ensures superior water repellency while maintaining breathability.
- Durable, long-lasting protection for both new and old concrete surfaces.
- Dries tack-free and skid-resistant.
- Water-based, colorless, and non-yellowing formulation.
- Actual VOC = 0 grams per liter, demonstrating environmental safety.
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.
