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.
Including the one-component environment-friendly polyurethane coating, the cement layer covering the coating and the facing bricks, the materials used per square meter generally do not exceed 400 yuan. In this way, for a bathroom with a size of 5 square meters, it will cost about 2,000 yuan to re-do waterproofing, and the bathtub and other bathroom facilities that need to be reconfigured will be calculated separately.
After the waterproof construction is completed, all the sewers in the bathroom should be blocked, and a “low wall” should be built at the door of the bathroom to conduct a water injection test. The water injection height should be about 20cm. Check after 24 hours. If there is no leakage on the walls and floors around the bathroom, it means that the waterproof quality of the bathroom is very good. On the contrary, it is necessary to find out the leak point and carry out maintenance.
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.
