We have a common ground, including concrete, cement mortar, terrazzo, marble, hardened wear-resistant surface, ground and other old coatings. Different floor base surface has a different approach. Concrete, mortar and other ground Firstly grinding machine grinding whole or using shot blasting, dust, clean the floor, the main purpose of doing so is to remove impurities in the ground, increasing the ground and coating adhesion. Terrazzo, hardened wear-resistant floor, marble floor approach: first, the degree of contamination of ground observation, and has waxed finish. If you want to use waxing to remove candle wax layer. Then use cleaning agents or solvents to remove oil, and finally polished using a grinding machine as a whole, to remove surface dirt. Old coating surface treatment methods: observation of the phenomenon of old ground without damage, whether the coating adhesion and coating the surface of a good degree of contamination. Then remove the old coating is not robust, the place to be used for damage sealer brush, then use the mortar to fill, after the final removal of surface dirt, paint the whole floor to finish. For concrete floor line has uniform requirements: a concrete floor curing drying time should be three weeks or more; b ground should be smooth tight compressive strength greater than 20MPa; c at the bottom of the concrete floor needs to do waterproofing or choice. good ventilation Waterborne Epoxy Floor; d if the substrate is not flat, you can increase the thickness of the floor coating to get a flat appearance.
