Sika Sikagard 705L – Silane-Based Reactive Water Repellent

Sika Sikagard 705L is a high-performance, solvent-free, silane-based reactive impregnation designed to provide long-lasting protection for concrete and cementitious substrates. With its 99% active ingredient formula, Sikagard 705L penetrates deeply into the substrate, reducing water absorption while enhancing resistance to de-icing salts, freeze-thaw cycles, and chloride ion penetration. This advanced water-repellent sealer is ideal for applications on bridges, parking decks, stadiums, and other concrete surfaces requiring long-term durability. The breathable formula allows vapor transmission, preventing trapped moisture issues while effectively repelling water.
