工艺流程解析
Process analysis
(1)基层处理
(1) Basic treatment
基层表面无浮土、砂粒等污物，表面应平整、无松动;阴阳角半径磨成光滑的小圆角;表面应平整、无松动。
The surface of base course shall be free of dirt such as floating soil, sand and other dirt, and the surface shall be flat and free from looseness; The radius of internal and external c钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具 保定空调维修 orners is ground into smooth small fillets; The surface shall be flat and free from looseness.
(2)细部附加层施工
(2) Detail additional layer construction
用毛刷防水堵漏材料，在管根部、地漏、阴阳角等容易漏水的薄弱部位均匀涂刷。地面与墙角交接处，涂膜防水卷材上，刷两次涂抹防水材料。
Use brush to prevent leakage and evenly brush the weak parts of pipe root, floor drain, internal and external corners which are easy to leak. At the junction of ground and wall corner, the waterproof roll of coating film shall be applied with waterproof material twice.
(3)涂膜
(3) Coating
用滚筒或者毛刷开始涂刷;第一层涂膜薄涂，第二层涂膜的涂膜方向与第一层涂膜的涂刮方向垂直。转角、接缝、变形缝等特殊部位必须仔细涂刷至符合要求，涂膜厚薄要均匀、封闭严密，不允许有露底、起鼓、脱落、开裂、翘边和收口密封不严等现象。安装规范要求涂膜防水厚度低于1.5MM.
Start painting with a roller or brush; The first layer of film is thin coated, and the direction of the second film is perpendicular to the direction of the first film. Special parts such as corner, joint and deformation joint must be carefully painted to meet the requirements. The thickness of the film shall be uniform and tightly sealed. It is not allowed to have the phenomenon of exposed bottom, drum, falling off, cracking, edge warping and tight sealing of the closing. The installation specification requires that the waterproof thickness of coating is less than 1.5mm
(4)试水试验
(4) Water test
在防水层干固后，在门槛部位砌一垄砖进行24小时闭水实验，看楼下楼顶是否有湿水点，无则证明防水施工是合格的。
After the waterproof layer is dry and fixed, a ridge of bricks is built at the threshold for 24-hour water closing test to see if there is wet water point on the roof of the downstairs. If there is no, it is proved that the waterproof construction is qualified.
