Silicone Waterproof Coating is a solvent-free silane and siloxane concentration blend. It is dilutable with organic solvents and can penetrate deep inside building substrates to form an efficient and lasting waterproofing layer. Diluted solutions serve as high-efficiency, general-purpose water repellents for impregnating and priming mineral and alkaline substrates.

Potassium methylsilicate is an alkaline aqueous solution generated by the reaction of potassium hydroxide and methylsilicic acid. It reacts with acidic substances in the air to form the active substance polymethylsilicic acid, creating superior waterproof properties specifically for mineral waterproofing agents.

• ✔ Deep Penetration: Effective depth of 3-10mm into the substrate.
• ✔ Natural Stone Compatible: Extremely effective with most types of natural stone.
• ✔ Alkali Resistance: Excellent performance on alkaline mineral surfaces.
• ✔ Vapor Permeability: Retains high water vapor permeability; does not clog pores or capillaries.
• ✔ Active Protection: Reacts with atmospheric moisture to generate long-lasting waterproof protection.

This product is ideally suited for the surface treatment of stone, brick, ceramic, concrete, cement mortar, perlite, and other mineral substrates.
