Pay attention to the construction of epoxy self-leveling floor paint, and take out the asphalt or soil in the expansion joint and clean it up; Filling expansion joints with materials; After being completely dried, all the ground will be polished clean to complete the leveling treatment. According to different ground conditions, a small amount of quartz powder is added to seal the surface pores when adsorbing resin. According to the hardness of the ground and the thickness of the pores, the effect after construction is different: when the resin absorbs quickly, the quartz powder stranded on the surface layer is loose and uncured, and the color is white; When the resin absorption is slow, the quartz powder solidifies with the resin, and the color is dark brown.

Mixing the main agent and the curing agent according to the correct proportion, and fully stirring; Mixing, and adding appropriate amount of quartz sand; Evenly daub the material with a spatula; The construction shall be completed within 30 minutes after the materials are mixed; The curing and hardening time of the intermediate coating is about 8 hours or more;
