Si20-DS – Diluted Ready To Use



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
