Curing agent is penetrated into concrete compound to have a series of complex chemical reaction with half hydrated cement,ca2,silica,and other materials resulting in new rigid materials.These compounds will enventurelly improve the compactness of the concrete surface layer to enhance the hardness, wear resistance, permeability resistance, etc. 

Use 300 mesh grinding machine to polish totally (or grind after wet-processing) to get clean concrete base surface.

Purpose: remove the original ground garbage, dust, floating pulp to open more pores of the original ground surface and let sealed concrete curing agent seep into the ground better.
