LITHIUM CONCRETE HARDENER TOP COAT: is a water-based ultrahigh solid lithium surface hardener used to densify, harden, dust-proof new or existing concrete floors. The product improves surface strength by hardening fresh and existing concrete surfaces and creating a capillary effect, prevents dust emission and is used to obtain a surface with high abrasion resistance. It creates an insoluble calcium silicate structure by reacting with calcium hydroxide and calcium carbonate existing in the active lithium concrete structure. Therefore, hardness of the concrete improves and dust-free surface is obtained.
