SI20-DS – Water Based Sealer And Densifier Ready To Use

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.

Key advantages

• • Significantly increases density, hardness and strength

• • Excellent dust proofing of substrates

• • Significantly reduces movement of water

• • Minimises efflorescence

• • High penetration into masonry surfaces

• • High wear resistance, UV stable, long life

• • Can be applied to damp or wet substrates
