第一步：填补空洞，铲除浮块。开槽处就如上法填实（装修公司估计不干），清扫浮尘，用开刀将地上水泥结块铲掉，因为它不是和地面真正连在一起的，将来会有隐患，费点力也值。清扫之后，用刷子在将管根，墙角的灰尘扫出来（笤帚在那个地方无能为力）。灰尘对防水膜影响最大，若不清扫干净，防水膜就不能真正和地面牢固结合在一起。清扫之后，用一两袋堵漏粉和成汤状用水桶或脸盆倒在地面上迅速用笤帚将浆汤扫到防水区的每一寸土地。此物干得巨快，1小时后就可以进行刷防水涂料的施工了。使用此物的目的有二：第一，它是一种防水材料，能起到防水效果。第二：再也不用担心灰尘的影响了，他将漏网灰尘彻底融合在浆汤中并与地面亲密接触。
Step 1: Fill the void and remove the floating block. Slot filling is just like the above method (decoration company estimates not to do), cleaning floating dust, using a knife to shovel the cement cakes on the ground, because it is not really connected with the ground, there will be hidden dangers in the future, it is worth a little effort. After cleaning, brush is used to remove the dust from the roots and corners of the pipe (broom can't do anything in that place). Dust has the greatest impact on the waterproof film. If it is not cleaned, the waterproof film can not really be firmly combined with the ground. After cleaning, pour one or two bags of leak-stopping powder and soup-like buckets or basins on the ground and quickly sweep the soup into every inch of the waterproof area with a broom. It dries so fast that it can be painted with waterproof paint in an hour. The purpose of using this material is twofold: first, it is a waterproof material, which can play a waterproof effect. Second: no longer need to worry about the impact of dust, he will completely fuse the leaking dust in the soup and close contact with the ground.
第二步：用堵漏粉和成粥状，。用刷子均匀涂刷在墙角四周和管线根，管线根做成直径20CM，墙角及管线均往上做20CM.目的：墙角和管线根是最容易漏水的地方，必须做加强。
Step 2: Use plugging powder and porridge. Brush evenly around the corner and the pipeline root. The diameter of the pipeline root is 20CM. Both the corner and the pipeline are 20CM upward. Objective: The corner and the pipeline root are the easiest places to leak water and must be strengthened.
加强根据管线和墙角的具体做：条件比较次的需要作八字内圆弧或八字外圆弧。条件一般的作上翻堵漏粉刷浆就可以。
Strengthen the concrete work according to the pipeline and the corner: the need for the lower conditions to make the eight-character internal arc or the eight-character external arc. Generally speaking, it can be done by turning over and plugging leak and painting slurry.
第三步：涂刷防水涂料，先用滚筒将四壁涂刷完毕，然后用刷子将墙角和管根细致涂刷，不要指望滚筒，它在这些细节上无用武之地。涂刷二遍，每遍必须干透（摸上去不粘手），每遍如上法涂刷。
Step 3: Paint the waterproof paint, first use the drum to finish painting the four walls, and then use the brush to meticulously paint the corner and root, do not expect the drum, it is useless in these details. Brush twice, each time must be thoroughly dry (feel not sticky hands), each time as above brush.
第四步：做保护层。用堵漏粉掺和水泥及界面剂和成粥状，均匀涂刷在防水膜上，要有一定厚度。目的：第一:不用再拉毛，方便贴砖。第二：本身含有防水材料，有防水效果。第三：避免因人员出入踩破防水膜和贴砖时脚手架，瓷砖硌破防水膜。
Step 4: Make a protective layer. It should be evenly coated on the waterproof film by mixing the leak stopper powder with cement, interfacial agent and porridge. Objective: Firstly, it is convenient to stick bricks without further hair pulling. Second: it contains waterproof material and has waterproof effect. Third: Avoid scaffolding when people step in and out to break the waterproof film and stick bricks, and crack the waterproof film by tile.
做完之后一定要做至少24小时的闭水试验。有漏出及时修补，修补方针是一处漏大面积修，本着宁错杀三千不使一处漏网。修完一定再做闭水试验。
After completion, the water closure test must be done for at least 24 hours. There are leaks to be repaired in time. The principle of repairing is to repair a leak in a large area. In the spirit of killing 3000 by mistake rather than making one leak. Closed water test must be done after repairing.
