1、 第一步就是清洗，首先可以使用洗洁精水液或洗衣粉水液清洗基础地面，再用清水冲洗干净，打扫干净的基础地面应当没有脏污处或其它浮松杂物。在清洗的同时，要对积水位做好标识标记。
1, the first step is to clean, first of all you can use detergent water or washing powder water cleaning the basis of the ground, and then rinse clean, clean the ground clean shall not dirty or other solid impurities. In the cleaning at the same time, the product level well logo mark.
2、 第二步就是找平处理，用专业底层TB-202按A组：B组=1：2.5(重量比)比例搅拌均匀(可加水调节施工稠度)，用胶刮板分两道以上刮涂于基面，要求必须把基础地面的空隙填平密封，保证干固后没有针孔，表面平整。不影响后面施工，若基面空隙较大，第一道刮涂时可加入A组份同等份量的细砂(40~80目)，搅拌均匀后刮涂。
2, the second step is leveling, with professional underlying TB-202 according to the A group: B group =1:2.5 (weight ratio) the proportion of mixing (water to regulate the construction consistency), with two or more rubber scraper scraping on the surface, the gap must be ground fill seal, ensure the dried without pinhole, smooth surface. Does not affect the construction, if the surface gap is big, the first scratch when adding fine sand A group share the same amount of (40~80 mesh), after mixing evenly coated.
3、 最后一步就是对积水片进行找平修补处理，直接按新水泥混凝土基础要求处理即可。
3, the last step is to water tablets for leveling repair processing, directly on the new cement concrete foundation requirements can be.
