Description
Si20-DS is a water based silicate and siliconate densifier-water repellent sealer for use on most types of porous limestone and concrete building materials.
Si Densifiers & Moisture Barriers – Silicates
Si Chemistry: Silicate based densifiers and moisture barriers are alkaline solutions containing soluble metal silicate salts. They are small molecules that when applied onto a substrate penetrate deep below the surface. They chemically react with cementitious substrates to form a cross-linked silicate polymer that permanently blocks substrate capillaries reducing the movement of water. The substrate becomes significantly denser, harder and stronger and is less susceptible to dusting.
