What waterproof coating** is suitable for the bathroom? This is what everyone has been paying attention to. In general, the leakage of water in the bathroom is caused by the details of the building. **There are three places that are prone to problems. We should all pay attention to them. These three places are floor drains, wall corners, and pipe roots. These three places are due to interfaces. If there are more, cracks are easy to appear, so water leakage is easy to occur. In addition, if the connection between the bathtub drain and the drain pipe is not tight, it is easy to produce gaps and leak water. So we should choose a coating that is ** suitable for bathroom decoration, so what waterproof coating ** is suitable for bathroom? Here I will tell you about it!

What waterproof coating ** is suitable for bathroom

We should choose one-component environmentally friendly polyurethane coating for waterproof coating, which is currently the waterproof material highly recommended by the Ministry of Construction. Because this kind of paint can tightly wrap the pipeline and the ground, penetrate into the gap, and will not shrink after drying, it is more suitable for use in small-area houses with pipes and gaps in the bathroom than rigid materials such as waterproof cement. Therefore, customers should choose brand-name paints when purchasing this type of paint, and the material cost per square meter is about 50-60 yuan.

It is understood that at present, some domestic brand polyurethane coating manufacturers have their own construction teams, and citizens can request the manufacturers to provide professionals when purchasing coatings. In order to make the waterproof period longer in the future, the paint generally needs to be brushed three times. In order to fully dry the paint, it is not possible to choose to do it in rainy or humid climates. Generally, the dry-out period of one-component environmentally friendly polyurethane coatings is about 3 to 4 days.

Counting the one-component environmentally friendly polyurethane coating, the cement layer covering the coating and the surface tiles, 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-waterproof, and the bathroom facilities that need to be reconfigured such as bathtubs are calculated separately.

After the waterproofing construction is completed, all the sewers of the toilet shall be blocked, and a 'low wall' shall be built at the door of the toilet for a water injection test, and the water injection height shall be about 20cm. Check after 24 hours. If there is no leakage on the surrounding walls and floor of the bathroom, the waterproof quality of the bathroom is good. On the contrary, it is necessary to find out the leaks and repair them.

At the same time, the walls should also be waterproofed. In order to achieve a better waterproof effect, the wall of the general bathroom also needs to be waterproofed about 30cm high to prevent the accumulation of water from bleeding through the wall. On the wall adjacent to the bathtub, the height of the waterproof treatment should be higher than the upper edge of the bathtub. Only in this way can it be guaranteed to be foolproof.
