1、基面处理:凿除旧混凝土面剥蚀层,用水冲洗干净,保持基本干净、坚实。
1, the base surface treatment: chisel in addition to the old concrete surface erosion layer, rinse with water, keep the basic clean and solid.
2、配制聚合物水泥防水砂浆 :干粉类按照水料比为15%的比例加水混合搅拌均匀即可,砂浆涂抹厚度在20-30mm为宜,配好的浆料应保证在0.5-1小时内用完,搅拌好的砂浆应注意防晒避风。

2, the preparation of polymer cement waterproofing mortar powder: water material ratio was 15% in the proportion of mixed with water and stir evenly, the mortar thickness 20-30mm is appropriate, slurry with good should be used within 0.5-1 hours, the well mixed mortar should pay attention to the sun shelter.

3、铺筑面积大时可用机械喷涂,分格施工。一次施工面积不宜过大,应分条分块错开施工,每块面积不宜大于10m2,错开施工的间隔不应小于24小时。分层施工时,留缝位置应互相错开。
3, paving area is large, you can use mechanical spraying, sub construction. A construction area should not be too large, should be sub block staggered construction, each area should not be greater than 10m2, staggered construction interval should not be less than 24 hours. In the layered construction, the joint shall be staggered from each other.
4、聚合物水泥防水砂浆摊铺完毕后应立即喷适量雾状水压抹并一次抹平,不宜反复抹压。遇有气泡时应刺破,表面应密实。立面或顶面的面层厚度大于10mm时应分层施工。每层抹面厚度宜为5-10mm,待前一层指触干时方可进行下层施工。
4, polymer cement waterproof mortar paving should be sprayed imtely after the appropriate amount of fog, water pressure, and once smooth, should not be repeated pressure. When there is a bubble, it should be punctured, the surface should be dense. When the thickness of the facade or top surface is greater than 10mm, the construction shall be layered. Each layer of plaster thickness should be 5-10mm, before a layer of dry to touch when can lower the construction.
5、施工后的砂浆层须养护7天。聚合物砂浆施工后,表面指触干燥后应进行喷雾养护或覆盖草帘、麻袋等保持潮湿。养护温度不宜底于5℃。聚合物砂浆施工24小时后,覆 盖塑料布潮湿养护七天,有条件时可定时洒水于表面。
5. The mortar layer shall be maintained for 7 days after construction. The polymer mortar construction, surface touch drying should be carried out after spray curing or covered grass, keep wet sack. Curing temperature should not be lower than 5 degrees centigrade. After 24 hours of polymer mortar construction, cover the plastic cloth for seven days, and spray on the surface regularly when conditions permit.
