1、屋面防水一般的施工工序
验收找平层→清理基层→配制水泥粘合剂→做附加层→基层施工→保护层→养护。卷材铺设粘结前，先将屋面防水卷材预铺开，找正，然后将屋面防水卷材两端对折卷起，把配制好的水泥粘合剂倒入基层上，并用刮板均匀的刮开，再将屋面防水卷材向前推铺，并及时用刮板排除遗留在屋面防水卷材内部的空气，刮出多余粘结剂。屋面防水卷材与找平层的粘结率≥85%。
Acceptance leveling layer → → formulated to clean the grassroots do an additional layer of cement binder → → → Base Construction protective layer → conservation. Before laying the adhesive sheet, the first pre-roll roofing membrane, alignment, and then fold the ends of the roof waterproofing membrane rolled, the preparation of a good cement adhesive poured onto the grass roots, and even with a scraper scratch, and then push forward roofing membrane shop, and promptly left on the roof with a scraper to exclude the air inside the waterproof membrane, scraped off the excess
adhesive. Bond rate roofing membrane and leveling layer ≥85%.
2、屋面防水接缝施工：隔汽层、防水层和附加层均采用搭接缝方法，用水泥粘合剂粘结，宽度为10cm。附加层接缝与防水层接缝错开5cm以上。屋面防水卷材搭接宽度长边8-10cm，短边10-15cm，相邻短边接缝应错开100cm以上，墙面与地面夹角处均为30cm以上。
Seam roofing construction: vapor barrier, waterproof layer and the additional layer are made of lap joint approach with cement adhesive bonding, a width of 10cm. Additional layer seams and waterproof layer joints staggered more than 5cm. Roofing waterproofing membrane lap width of the long side 8-10cm, short side 10-15cm, adjacent short side seams should be staggered over 100cm,walls and floor are at an angle of more than 30cm.
3、卷材铺粘完毕后，需在防水层上做1：2.5水泥砂浆厚度为2cm的保护层，分二次抹成，二层接茬必须错开20cm以上，保护层要求平整，并洒水养护。
After completion of sticky web shop, you need to do on a waterproof layer: 2.5 cement mortar protective layer thickness of 2cm, divided into secondary wipe, floor Jiecha must be staggered more than 20cm, the protective layer should be smooth and sprinkler maintenance.
4、使用无纺布降低防水层受结构运动作用，加一条泡过柔韧型防水浆料的无纺布在裂缝处。
Waterproof layer by reducing the use of non-woven structure of sports action, plus a flexible waterproofing slurry bubble nonwovens in the cracks.
5、做水泥砂浆保护层，用水泥砂浆在干固后的防水层上涂刷做保护层。
