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(jiān)實(shí)。
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(lèi)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(yīng)保證在0.5-1小時(shí)內(nèi)用完,攪拌好的砂漿應(yīng)注意防曬避風(fēng)。
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(shí)可用機(jī)械噴涂,分格施工。一次施工面積不宜過(guò)大,應(yīng)分條分塊錯(cuò)開(kāi)施工,每塊面積不宜大于10m2(天津塑料托盤(pán)),錯(cuò)開(kāi)施工的間隔不應(yīng)小于24小時(shí)。分層施工時(shí),留縫位置應(yīng)互相錯(cuò)開(kāi)。
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(yīng)立即噴適量霧狀水壓抹并一次抹平,不宜反復(fù)抹壓。遇有氣泡時(shí)應(yīng)刺破,外觀應(yīng)密實(shí)。立面或頂面的面層厚度大于10mm時(shí)應(yīng)分層施工。每層抹面厚度宜為5-10mm(網(wǎng)絡(luò)營(yíng)銷(xiāo)),待前一層指觸干時(shí)方可進(jìn)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(yǎng)護(hù)7天。聚合物砂漿施工后,外觀指觸干燥后應(yīng)進(jìn)行噴霧養(yǎng)護(hù)或覆蓋草簾、麻袋等保持潮濕。養(yǎng)護(hù)溫度不宜底于5℃。聚合物砂漿施工24小時(shí)后(廣告策劃公司),覆蓋塑料布潮濕養(yǎng)護(hù)7天,有條件時(shí)可準(zhǔn)時(shí)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.
