| 1.首先对混凝土（水泥）基础地面凹凸不平的区域用环氧树脂加石英砂进行修补找平，实干后用打磨机打磨掉浮动，明显凸出部分，清理干净后就可以做底漆施工。（平整度好，基础地面没有凹凸不平的就可以直接打磨清理）。 1. Firstly, the uneven area of concrete (cement) foundation ground is repaired and leveled with epoxy resin and quartz sand. 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.混凝土地面裂缝的修补：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. Repair of concrete ground cracks: For the thicker cracks, repair materials can be used to repair directly. For the finer cracks, electric cutting machine should be used to cut the cracks about 1 cm wide along the cracks, and then epoxy mortar + 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 floor is above C25, and the epoxy floor coating can be laid directly after polishing and cleaning with a grinder without sand or powder. 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 powder on the surface of the foundation: the floating layer and loose matter are removed by sandblasting or other mechanical treatment, 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3-5cm的水泥找平层再做环氧地坪涂层。 5. The phenomenon of sand or flour on the surface of foundation is very serious. It is suggested that 3-5 cm cement leveling layer be laid again and epoxy floor coating be made. |
