世界中央我孤独的漂亮 07-10 09:25

一、材料要求
1. 聚氨酯涂膜防水材料(双组份)，应有出厂合格证，应经复试合格后使用。
甲组份是以聚醚树脂和二异氰酸酯等原料，经过聚合及反应制成的含有端异氰酸酯基的聚氨基甲酸酯预聚物，外观为浅黄粘稠状，桶装，每桶20kg。
乙组份是由固化剂、促进剂、增韧剂、防霉剂、填充剂和稀剂等混合加工制成，外观有红、黑、白、黄及咖啡色等，膏状物，桶装，每桶40kg。
二、主要机具
1. 一般应备有电动搅拌器(功率0.3-0.5KW,200-500r/min)、搅拌桶(容积10L)，油漆桶(3L)、塑料或橡胶刮板、滚动刷、油漆刷、弹簧秤、干粉灭火器等。
三、作业条件
1. 涂刷防水层的基层表面，必须将尘土、杂物等清扫干净，表面残留的灰浆硬块和突出部分应铲平、扫净，抹灰、压不，阴阳角处应抹成圆弧或钝角。
2. 涂刷防水层的基层表面应保持干燥，并要平整、牢固，不得有空鼓、开裂及起砂等缺陷。
3. 在找平层接地漏、管根、出水口、卫生洁具根部(边沿)，要收头圆滑。坡度符合设计要求，部件必须安装牢固，嵌封严密。经过验收。
4. 突出地面的管根、地漏、排水口、阴阳角等细部，应先做好附加层增补处理，刷完聚氨酯底胶后，经检查并办完隐蔽工程验收。
5. 防水层所用的各类材料，基层处理剂、二甲苯等均属易燃物品，储存和保管要远离火源，施工操作时，应严禁烟火。
6. 防水层施工不得在雨天、大风天进行，冬期施工的环境温度应不低于5℃。
四、操作工艺
1. 工艺流程
清理基层表面→细部处理→配制底胶→涂刷底胶(相当于冷底子油) →细部附中层施工→第一遍涂膜→第二遍涂膜→第三遍涂膜防水层施工→防水层
一次试水→保护层饰面层施工→防水层二次试水→防水层验收
2. 防水层施工前，应将基层表面的尘土等杂物清除干净，并用干净的湿布擦一次。
3. 涂刷防水层的基层表面，不得有凸凹不平、松动、空鼓、起砂、开裂等缺陷，含水率一般不大于9%。
4. 涂刷底胶(相当于冷底子油)：
1) 配制底胶，先将聚氨酯甲料、乙料加入二甲苯，比例为1:1.5:2(重量比)配合搅拌均匀，配制量应视具体情况定，不宜过多。
2) 涂刷底胶，将按上法配制好的底胶混合料，用长把滚刷均匀涂刷在基层表面，涂刷量为0.15-0.2kg/m2，涂后常温季节4h以后，手感不粘时，即可做下道工序。
5. 涂膜防水层施工：聚氨酯防水材料为聚氨酯甲料，聚氨酯乙料和二甲苯，配比为1:1.5:0.2(重量比).
1) 在施工中涂膜防水材料，其配合比计量要准确，并必须用电动搅拌机进行强力搅拌。
2) 附加层施工：地面的地漏、管根、出水口，卫生洁具等根部(边沿)，阴、阳角等部位，应在大面积涂刷前，先做一布二油防水附加层，两侧各压交界缝200mm。涂刷仿水材料，具体要求是，常温4h表干后，再刷第二道涂膜防水材料，24h实干后，即可进行大面积涂膜防水层施工。
3) 涂膜防水层：第一道涂膜防水层：将已配好的聚氨酯涂膜防水材料，用塑料或橡皮刮板均匀涂刮在已涂好底胶的基层表面，每平方米用量为0.8kg，不得有漏刷和鼓泡等缺陷，24h固化后，可进行第二道涂层。

涂膜防水是指在自身具有—定防水能力的结构层表面涂刷一定厚度的防水涂料，室温固化，形成一层具有一定的韧性防水涂料防水方法根据基本情况和防水配件。加固和缓冲材料放置在防水层内，以提高效果的防水涂料防水层，提高强度和耐久性。室内装修防水层首先，敲开地面瓷砖及上返一块瓷砖也要敲掉。然后，清理干净渣土，露出基面。　
　1、此时的基面应呈麻面，可直接采用劳亚尔搅拌水泥砂子制成的防水砂浆进行搓砂抹面，阴角和墙根及卫生洁具周边要做成R角。防水、找平一次搞定。　　防水砂浆层凝固后(以可上人为标准)，用劳亚尔搅拌水泥制成防水素灰浆涂刷一次，表干(约30分钟)即可粘贴瓷砖。　　
2、用搅拌水泥制成防水素灰浆涂刷一次，表干后用劳亚尔搅拌水泥砂子制成防水砂浆，进行搓砂抹面，防水砂浆层凝固后即可做关水实验，如无问题即可粘贴瓷砖。
希望我的回答能帮助到你

卫生间地面肯定是必须要做防水的，做防水之前一定要把准备做防水的基层打扫干净，尽量保持表面的干燥。
2、卫生间的墙面也需要作防水，淋浴区墙面要做到180厘米，其他墙面做到30厘米。
3、另外有一点很重要，其实卫生间的漏水部位主要在上下水管的根部和墙脚，所以这些地方也需要做30厘米的防水，而且做防水时一定要让它“吃饱”。
4、水电改造、开槽破坏原防水层的，要重做防水。

阳台，屋顶，露台等就建议需要K11防水浆料柔韧型和砂浆防水剂结合施工了，这样刚柔结合，才可以抵挡日晒雨淋的侵蚀，保证良好的防水效果。
