I believe that the construction process of epoxy floor paint should know that the ground grinding is a very important process in the construction of epoxy floor paint. The main functions of ground polishing are: clearing dust and debris on the base floor to obtain a certain level surface; ground polishing and brushing can enhance the adhesion and improve the adhesion of floor paint coating; if ground polishing is not smooth, the coating effect is poor. Then, to what extent can epoxy floor paint be constructed by grinding the base floor? The epoxy floor paint manufacturer suggests that the ground treatment is to grind loose layer, delamination and cement residue until it is hard and smooth. After grinding, dust, cement residue and other debris on the surface can be cleaned up, and the construction of epoxy floor paint can begin as shown above.环氧地坪漆施工前水泥地面处理方法：
Cement ground treatment before construction of epoxy floor paint:
1. Firstly, the uneven area of concrete cement foundation ground is repaired and leveled with quartz sand coated in Guanglei epoxy. After drying, the floating part is polished with a grinder, and the prominent part is obvious. After cleaning, the primer construction can be done. (With good smoothness, the foundation floor can be directly polished and cleaned without bumps).2、对于较粗的裂缝可用修补材料直接修补对于较细的裂纹需先用电动切割机沿裂缝切开约1公分宽的缝，然后用环氧砂浆+玻纤布加强修补。
2. For coarser cracks, repairing materials can be used to repair them directly. For finer cracks, electric cutting machine should be used to cut the cracks about 1 cm wide along the cracks, and then epoxy mortar and fiberglass cloth should be used to strengthen the repair.3、基础地面强度达C25以上，不起砂不起粉，就直接用打磨机打磨、清洁后就可以铺设环氧地坪涂层。
3. The strength of the foundation ground is above C25. If the sand is not enough and the powder is not enough, the epoxy floor coating can be laid directly after polishing and cleaning with a grinder.4、基础表面有起沙或起粉现象：用喷砂或其它机械处理除去浮层和松散物，使表面坚硬、粗糙和均匀。然后，用草酸进行酸洗地面，再用清水反复冲洗彻底刷洗水泥表面。仔细检查打磨结果，如有需要进行再次打磨。
4. There is sand or silting on the surface of the foundation: sand blasting or other mechanical treatment is used to remove the floating layer and loose matter, so that the surface is hard, rough and even. Then, acid wash the floor with oxalic acid, then rinse the cement surface with clean water repeatedly and thoroughly. Check the grinding results carefully and re-grind if necessary.5、基础表面起沙或起粉现象非常严重：建议重新铺设4cm的水泥找平层再做环氧环氧地坪涂层。
5. The phenomenon of sand and flour on the surface of foundation is very serious. It is suggested that the cement leveling layer of 4cm should be laid again and then the epoxy floor coating should be made.
