Leakage and water seepage in the bathroom are the most complained cases at present. Doing a good waterproof work in the bathroom includes not only whether the waterproof construction is in place, but also the quality of the waterproof material. Floor drains, wall corners, and pipe roots are the most problematic details. Experienced people recommend: it is best to choose a single-component environmentally friendly polyurethane coating for waterproof materials.
This kind of coating can tightly wrap the pipeline and the ground, penetrate into the gap, and will not shrink after drying. Therefore, it is more suitable for small-area houses with many pipelines and gaps in the bathroom than rigid materials such as waterproof cement. When purchasing this type of paint, you should choose brand paint, and the material cost per square meter is about 50-60 yuan.
It is understood that some domestic brands of polyurethane coating manufacturers have their own construction teams. Citizens can ask manufacturers to provide professionals while purchasing coatings.
In order to make the waterproof period longer in the future, the paint generally needs to be painted 3 times. In order to let the paint fully dry, it is not possible to choose to do it in rainy or humid weather. Generally, the drying period of one-component environmentally friendly polyurethane coatings is about 3 to 4 days.
包括单组份环保聚氨酯涂料、覆盖涂料的水泥层和面砖，每平方米用料一般不超过400元。这样，一个5平米的卫生间，重新做防水需要2000元左右，浴缸等需要重新配置的卫浴设施另算。
防水施工完成后，应将卫生间内的下水道全部堵死，并在卫生间门口筑起“矮墙”进行注水试验。注水高度应在20cm左右。 24 小时后检查。如果卫生间周围的墙壁和地面没有漏水，说明卫生间的防水质量非常好。反之，则需要找出泄漏点，进行维修。
The walls should also be waterproofed. In order to achieve a better waterproof effect, the wall of the general bathroom should also be waterproofed with a height of about 30cm to prevent the accumulated water from seeping through the wall. On the wall adjacent to the bathtub, the height of the waterproof treatment should also be higher than the upper edge of the bathtub.
Therefore, there must be no loopholes in the waterproof work of the bathroom, otherwise a small problem will bring endless troubles, and once there is a leak in the bathroom, it will be very troublesome to remedy.
