1、屋面防水一般的施工工序
驗收找平層→清理基層→配制水泥粘合劑→做附加層→基層施工→保護層→養(yǎng)護。卷材鋪設粘結(jié)前，先將屋面防水卷材預鋪開，找正，然后將屋面防水卷材兩端對折卷起，把配制好的水泥粘合劑倒入基層上，并用刮板均勻的刮開，再將屋面防水卷材向前推鋪，并及時用刮板排除遺留在屋面防水卷材內(nèi)部的空氣，刮出多余粘結(jié)劑。屋面防水卷材與找平層的粘結(jié)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、屋面防水接縫施工：隔汽層、防水層和附加層均采用搭接縫方法，用水泥粘合劑粘結(jié)，寬度為10cm。附加層接縫與防水層接縫錯開5cm以上。屋面防水卷材搭接寬度長邊8-10cm，短邊10-15cm，相鄰短邊接縫應錯開100cm以上，墻面與地面夾角處均為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、卷材鋪粘完畢后，需在防水層上做1：2.5水泥砂漿厚度為2cm的保護層，分二次抹成，二層接茬必須錯開20cm以上，保護層要求平整，并灑水養(yǎng)護。
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、使用無紡布降低防水層受結(jié)構(gòu)運動作用，加一條泡過柔韌型防水漿料的無紡布在裂縫處。

5、做水泥砂漿保護層，用水泥砂漿在干固后的防水層上涂刷做保護層。
