1.清理基层：表面应平整、干净、干燥，细部构造应达到设计要求，如有缺陷应进行处理，合格后方可进行防水施工。
1 clean up the grassroots: The surface should be smooth, clean, dry, detailed structure should meet the design requirements, if any defects should be treated, waterproof construction can be carried out after passing.

2.涂刷基层处理剂：自粘防水卷材基层处理剂开桶后应充分搅拌，用滚刷均匀的涂刷于基层（参考用量为0.2kg/m2）。待基层处理剂完全干燥后铺贴自粘防水卷材。
2 brushing primary treatment agent: self-adhesive waterproof membrane primary treatment agent should stir after opening bucket with brush evenly brushing the grass roots (refer to the amount of 0.2kg / m2). After primary treatment agent to be completely self-adhesive waterproof membrane dry paving.

3.节点处理：管根部位如雨水管、穿樯管等%考试大%部位的管根需先做密封处理后，再铺贴附加层；转角部位如阴阳角、平立面转角铺贴附加层；伸缩缝、施工缝等部位铺贴附加层。附加层的水平面和垂直面宽度均应≥250mm.
3 node processing: Tube root parts of rain water pipes, tubes, etc.% mast wear test test large parts of the tube% sealed root need to do first, and then an additional layer of paving; corner site, such as yin and yang angle, flat facade Corner Stones additional layers; expansion joints, construction joints and other parts of the additional layer of paving. Horizontal and vertical width of the additional layer should ≥250mm.

4.铺EVA防水卷材：先确定卷材铺贴顺序和方向，并在基层弹线，然后铺贴卷材。铺贴自粘防水卷材时，先揭下隔离纸，将有粘性的一面沿基准线铺贴，随揭隔离纸（膜）随即滚压卷材的表面并挤压出空气，以确保初始粘结强度。卷材纵向搭接缝要顺直，搭接缝宽度30 ~50 mm，用滚筒用力压实，确保防水卷材之间粘接牢固。
4 Shop EVA waterproofing membrane: Stones roll to determine the order and orientation, and at the grassroots level playing cord and Stones roll. Stones self-adhesive waterproof membrane, the first release paper peeled off the adhesive side paving along the baseline, then rolling over to expose the surface membrane separator paper (film) and squeeze out the air, in order to ensure that the initial sticking knot strength. Coil longitudinal lap seam to straight, lap seam width 30 ~ 50 mm, with a roller compaction force to ensure a solid bond between the waterproofing membrane.

5.卷材搭接与卷材收头处理：卷材采用搭接方式，通过卷材高分子层搭接焊接，将两幅卷材搭接在一起。无论是水平收头，还是垂直收头，应对收头边处采用配套密封胶密封，卷材在立面收头时，应用金属压条固定，再用配套密封胶将金属压条上口和固定螺钉密封。
5 sheet lap and closed head coil treatment: membrane using an overlap, lap welding polymer layer through the coil, the two coils lap together. Whether it is the level of income head, or vertical closed head, closed head side to deal with ancillary office uses sealant, roll the head when closed facade, the application of metal layering fixed, and then supporting sealant bead catchy metal seal and fixing screws .

6.质量验收：防水层验收合格，进行下一道施工程序。自粘防水卷材出现破损或鼓泡时，应将破损部分清洁干净后，用大于破损部位边缘100 mm的卷材修补压实封口。
6. quality acceptance: acceptance waterproof layer, conducted under a construction program. Self-adhesive waterproof membrane appears damaged or bubbling when damaged part should be cleaned after use damaged parts is greater than 100 mm of the edge sealing membrane repair compaction.
