SpecSilane 40 WB

40% solids water-based penetrating silane sealer


SpecSilane 40 WB is a 40% solids, 100% reactive, waterborne silane sealer. This clear, penetrating, breathable water repellent is designed for use on interior and exterior above-grade concrete or masonry surfaces.

SpecSilane 40 WB penetrates the surface and bonds directly with the substrate, which results in a surface that is highly resistant to both moisture and salt.

SpecSilane 40 WB 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. VOC compliant.
