家居必备卫生间防水施工技巧

Waterproof construction techniques for essential toilet in home

卫生间是家庭室内长期涉水的部位，虽然面积不大，但存在的细部节点较多，如地漏、穿楼板管道、阴阳角、门口过门石、洗手盆墙面、淋浴墙面等，任何一个部位处理不当都会给日后的使用留下漏水隐患。一旦出现渗漏，就会影响到楼下邻居，严重的还会惹上官司。

Toilet is a long-term part of the family indoor water, although the area is not large, but there are more detail nodes, such as floor drain, floor pipe, yin and yang angle, doorway stone, hand wash basin wall, shower wall and so on, any part of improper disposal will leave the hidden water hidden danger to the future use. Once there is leakage, it will affect downstairs neighbors, and it will also lead to serious lawsuits.

出现渗漏，解决渗漏问题就得进行维修，我们先粗略算一下维修成本，基本工序是铲砖、水泥砂浆结合层、原防水层到结构层，重新购买材料，新做防水之后，还要恢复到面砖层，那么维修费用可能是您当初做防水费用的3-5倍，甚至更高。

Leakage, leakage problems will have to be repaired, we first roughly calculate the maintenance cost, the basic process is the shovel bricks, cement mortar layer, the original waterproof layer to the structural layer, the re purchase of material, after the new waterproof, but also to restore to the face brick layer, then the maintenance cost may be 3-5 times the cost of your original waterproof cost. And even higher.

做任何事情都要防患于未然，我们在前期做防水的时候就要特别注意卫生间的细部节点部位，正可谓，细节决定成败。

Do everything to prevent it in the bud, we should pay special attention to the details of the bathroom nodes when we do waterproof in the early stage. It is to be said, the details decide success or failure.

基层清理

Grass-roots cleaning

基层表面应平整、坚实、洁净，无尖锐角、明水和缝隙。遇到防水涂膜与基层粘结不牢的现象，就是因为基层没有处理干净，揭开涂料背面，一定是粘着浮灰。

The surface of the base should be smooth, solid and clean, without sharp corners, clear water and cracks. When the waterproof coating is not firmly adhered to the base, it is because the grass roots are not clean enough to uncover the back of the coating.

阴角、管根抹弧与附加层施工

Construction of negative angle, pipe root arc and additional layer

很多人会忽略抹弧这一道工序，因此可能会遇到阴角与管根周边开裂。抹弧是为了避免涂料在直角处堆积而导致的开裂问题。

Many people will ignore the process of arc cleaning, so it may encounter cracks around the corner and the root of the pipe. The arc is used to avoid cracking caused by the accumulation of paint at right angles.

阴角与管根附加层施工需要“一布两涂”，即先薄刷一遍防水涂料，未固化前再铺贴网格布，然后再涂一遍防水涂料覆盖网格布。（卫生间做防水，建议选择性价比较高的水泥基防水涂料）

The construction of the shade angle and the additional layer of the pipe root needs "one cloth two coating", that is, to brush the waterproof coating first, and to paste the mesh cloth before it is not solidified, and then apply the waterproof coating to cover the mesh cloth. (toilet is waterproof, it is recommended to choose cement based waterproof coating with high cost performance).

大面涂刷施工

Large surface brush construction

在细部附加层干燥成膜后，即可进行大面施工。涂刷第一道涂膜，涂刷时要均匀，不能有局部堆积，并要多次涂刷使涂料与基层之间不留气泡。待第一道涂层干燥后（以不粘手为准），进行第二遍涂膜的施工，涂刷方向与上一道相互垂直，干燥后再涂刷下一遍涂膜。涂膜的收头应多遍涂刷，以保证完好的防水效果。

After the additional layer is dried and film-forming, the large surface can be constructed. The first coating should be brushed. When painting, it should be uniform. There should be no local accumulation, and it should be repeatedly painted to keep the bubbles between the coating and the base. After the first coating is dry (not stick to the hand), the second times of the construction of the coating, the direction of the painting and the above one perpendicular to each other, after drying and then brush the next film. The coating head should be painted several times to ensure good waterproof effect.

涂刷高度：淋浴墙1800mm高，洗手盆1200mm高，其他部位500mm高。

Brush height: shower wall 1800mm is high, washbasin 1200mm is high, 500mm of other parts is high.

闭水试验

Water closed test

待涂料完全干燥后，封好下水口，最高点蓄水深度不少于20mm，蓄水时间不少于24小时，检查无漏点，为合格。

After the coating is completely dried, seal the bottom outlet. The maximum storage depth is not less than 20mm, and the storage time is not less than 24 hours.
