SPECSILANE 40 is a 40% solids, 100% reactive, silane sealer. This clear, penetrating, breathable water repellent is designed for use on interior and exterior above grade concrete or masonry surfaces. SPECSILANE 40 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 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. V.O.C. compliant.
