CETEX LD is concentrated premium nano-lithium silicate based densifier/hardener for cementatious surfaces. Being the smallest stable silica, it penetrates deep in the concrete to produce insoluble calcium silicate hydrate and silica gels within concrete pores. Once pores are filled, silica polymerization takes place on the surface and lithium comes out of the system as insoluble lithium carbonate powder. This results in microscopic, alkali-free silica (glass) layer, which is not possible in other silicate based densifiers. This not only reduces liquid penetration, dusting, but also results in pure silica coating (glass), which has high resistance to abrasion & heat and reduces maintenance.
