Liqui-Hard is specifically designed to produce hardened, dust-proofed and improved chemically resistant surfaces wherever it is applied. Through a chemical reaction process, Liqui-Hard penetrates progressively through the concrete and chemically solidifies all the component parts into a homogenous concrete mass.
Besides its densifying and hardening action, Liqui-Hard solidifies the concrete eliminating dusting, rotting and pitting. Liqui-Hard meets maximum VOC content limits of 400 g/L for Concrete Protective Coatings as required by the U.S. EPA Architectural Coatings Rule.
Liqui-Hard when used on a concrete surface, penetrates progressively through the concrete and chemically converts the weak calcium hydroxide and calcium carbonate compounds in the concrete to form beneficial calcium silicate hydrate (CSH) producing a hard, dense, and sealed surface.
The process is basically a chemical reaction between the free lime or calcium hydroxide and Liqui-Hard to chemically convert bad aspects into good ones, through a process of crystalline growth.
