Si20-D

Si20-D is a ready to apply, sodium silicate based densifier, hardener and dust proofer for concrete and cementitious substrates. Si20-D penetrates concrete and reacts to form a permanent Calcium Silicate Hydrate (CSH) structure within the pores. Treated surfaces are harder and stronger with a permanently reduced porosity reducing the movement of water and minimising efflorescence.

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
