SIF - Si20 - DS - Concrete Densifier and Sealer (Ready to Use) 20 Ltr Drum Only

Si20-DS

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
