Si20 – D – Water Based Sealer Densifier RTU


SKU: Si20D Category:


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
