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, surface treatment: chiseling the old concrete surface layer erosion, water rinse, keep clean, solid.


2、配制聚合物水泥(屋顶)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(天津塑料托盘),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, the construction area of large mechanical spraying, sub grid construction. A construction area should not be too large, should be staggered construction division, each area should not be larger than 10m2, staggered construction intervals of not less than 24 hours. Layered construction, seam position should be staggered with each other.


4、聚合物水泥(屋顶)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,外观应密实。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(网络营销),待前一层指触干时方可进行基层施工。
4, the polymer cement waterproof mortar paving shall be immediately after spraying the amount of water mist and wipe a smooth, wiping pressure should not be repeated. In case of air bubbles should be punctured, the surface should be dense. When the thickness of the surface layer of the facade or top surface is greater than 10mm. 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,外观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(广告策划公司),覆盖塑料布潮湿养护7天,有条件时可准时洒水于外观。
5, the construction of the mortar layer to be maintained for 7 days. 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 at 5. 24 hours after the construction of polymer mortar, covered with plastic cloth wet curing for 7 days, when the condition can be regularly spray on the surface.
