Sodium silicate in two, three, maybe four alum configured to two alum, alum, three and four alum fast setting waterproofing agent, the waterproofing agent agglutination rate is generally not overstepping one minute, the engineering use of its role and adhesion, quick-setting, mixed with cement mortar and concrete, used to repair, lost circulation, repair, surface treatment, because the agglutinate agile, water glass when soaking process of porous materials, Its density and strength improve.

For clay bricks, silicate products, cement concrete, etc., have outstanding effect, but not to besmear to brush or dipping gypsum products, because of sodium silicate and sodium calcium sulphate produce chemical reaction will happen, in the products of pore crystallization, obvious swelling volume, and then cause the damage of the products, not with cement waterproof mortar, used as a roof or rigid waterproof layer of the earth, such as.

Hospitals, pharmacy, machinery, government agency, school, factory, airport terminal, but as the time to add, its surface is extremely brief began to appear crack, the oil pollution, the color becomes dark, so in order to let the terrazzo floor to reproduce the glory, for in situ after moistureproof processing, on a new layer again, the selection of new surface data should consider to choose high strength, wear resistance.
