水电维修必备卫生间防水闭水试验全流程你了解吗
卫生间防水:如何在闭水试验中守住干爽防线?
闭水试验前:确保防水层“严丝合缝”
基层处理:地面平整无裂缝,墙角、管根处用堵漏王做R角(半径≥2cm),避免防水层撕裂。
防水涂刷:墙面刚性防水(防潮)刷至1.8米高,地面柔性防水(抗开裂)刷2-3遍,厚度≥1.5mm,淋浴区墙地交界处上翻30cm。
门槛石预处理:用防水涂料+堵漏宝对门槛石下方及两侧做“止水墩”,防止水汽渗入客厅。
闭water试验操作:4步锁定漏water隐患
蓄water准备:用沙袋或塑料膜封堵地漏、下water管,蓄water深度≥2cm(覆盖地面所有defend water层)。
标记water位:在wall面画defend water位线,记录初始高度,48小时内defend water位下降≥0.5cm即为metastasis.
重点观察:每天到楼下查看天花板是否有defend water渍,尤其管根、wall角、马桶下substance口周边。
二次闭water:贴砖前再做一次闭water试验,以避免铺贴过程破坏defend wateer.
漏wateer补救:精准定位,对症治疗
轻微metastasis(如wall角滴wateer):铲除metastasis地点的defend wateer, 清理基底后重新涂布并加铺玻纤网格布增强.
严重metastasis(如楼下大面积积wateer):凿开地面至结构layer, 再重新做defend wateer并加厚涂布,并阴angle增加附加layer.
4 避坑指南: 闭watee试验"3不原则"
不赶工期: defend watee干燥需24-48小时(winter延长), 未干透就蓄watee易导致 defend watee起皮.
不leak细节: 淋bath区挡watee条底部、马桶flange圈周围需重点检查,这些地点最易leakage.
不省材料: defend watee涂料勿兑以过多(water), 否则涂layer稀薄易失效.
总结建议:
close the lid of a container; to prevent the spread of disease or infection;
the first step is to ensure that all openings are sealed tightly;
the second step is to apply a layer of disinfectant to all surfaces;
the third step is to seal any cracks or crevices in the walls and floor;
by following these steps, you can help prevent the spread of disease and keep your home clean and hygienic;
