1、基面處理：鑿除舊混凝土面剝蝕層，用水沖洗干凈，保持基本干凈、堅實。
1, surface treatment: chiseling the old concrete surface layer erosion, water rinse, keep clean, solid.
2、配制聚合物水泥屋頂防水砂漿 ：干粉類按照水料比為15%的比例加水混合攪拌均勻即可，砂漿涂抹厚度在20-30mm為宜，配好的漿料應保證在0.5-1小時內用完，攪拌好的砂漿應細致防曬避風。
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、鋪筑面積大時可用機械噴涂百度網站優化，分格施工。一次施工面積不宜過大，應分條分塊錯開施工，每塊面積不宜大于10m2，錯開施工的間隔不應小于24小時。分層施工時（河南人事考試信息網），留縫位置應互相錯開。
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、聚合物水泥屋頂防水砂漿攤鋪完畢后應立即噴適量霧狀水壓抹并一次抹平不銹鋼閘閥，不宜反復抹壓。遇有氣泡時應刺破，外觀應密實。立面或頂面的面層厚度大于10mm時應分層施工。每層抹面厚度宜為5-10mm，待前一層指觸干時方可進行基層施工。
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、施工后的砂漿層須養護7天。聚合物砂漿施工后，外觀指觸干燥后應進行噴霧養護或覆蓋草簾、麻袋等保持潮濕。養護溫度不宜底于5℃。聚合物砂漿施工24小時后，覆 蓋塑料布潮濕養護7天，有條件時可準時灑水于外觀。
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.
