If you want your house to be well-equipped, you must first do a good job of waterproofing. Many people don’t know the meaning of waterproofing, and how the workers did the construction. They didn’t realize that the waterproofing was not done well until they moved in. The neighbors downstairs knocked on the door every day to complain, especially when they were taking a shower. Therefore, when workers are constructing, we should know which places need to be waterproofed? What kind of standards are they?
The bathroom is a relatively humid area, and there is often water on the ground, so the waterproofing of the bathroom must be strictly implemented to ensure foolproofness. After the waterproofing is completed, a closed water test is required. Then let’s take a look at the common problems of waterproofing.
1. Selection of waterproof material
There are many kinds of waterproof materials, and because of the small area of the bathroom, there are many internal and external corners, and there are many floor pipes, so it is necessary to choose waterproof materials with good adhesion and elasticity.
2. Construction process
1. First of all, the base treatment should be carried out first. Generally, the floating dust on the base surface, cement agglomeration and loose base should be cleaned first; the pipe roots, drainage holes, yin and yang corners, and the holes left after the wall hydropower improvement should be treated. Because it is plastered into a circular arc, if there are uneven or cracked parts, it needs to be repaired and leveled again.
2. Next, you must first understand the proportion knowledge of the deployment of waterproof materials. If the proportion of materials is wrong, the original effect will not be achieved.
3. When we paint waterproof materials, we should paint from top to bottom, first on the wall and then on the ground. It needs to be brushed twice, and the time interval between the first pass and the second pass is about 4-8 hours. Remember that the premise of the last painting must be that the first waterproof layer is not sticky, and the two painting before and after are in a cross.
4. Sometimes different waterproof materials are selected, and the number of times is also different, but generally 2-3 times.
5. Generally, when we paint waterproof materials, the waterproof height of the shower wall should be 180cm, while the non-shower wall should not be less than 30cm. However, in order to better play a waterproof role, it is recommended to unify the height of 180cm, and for the modified light wall and self-built light wall, it is recommended to uniformly brush to the top.
6. The thickness of the waterproof layer must be 1.5mm thick according to the national acceptance specification.
The above waterproof construction steps must be constructed in accordance with the specifications, and there must be no mistakes.
After talking about the steps of waterproofing the bathroom, let’s talk about those places that need to be carefully waterproofed.
In the bathroom, the places that are most likely to leak are: the location of the floor drain, small water pipes, floor joints and toilet pipes. Therefore, attention should be paid to these places during construction. Other places can be brushed twice for waterproofing, but these places are best brushed several times. In addition, the place with the most leakage is under the gate stone, so we need to make a zone under the gate stone in advance, and the waterproof needs to be rolled up on the zone, so as to form a basin shape to achieve the function of water storage and water retention.
Finally, let’s talk about the closed water test after the bathroom is waterproof, which is the most critical step.
When we do the closed water test, we must wait for the waterproof material to dry completely. Before closing the water, we need to plug the floor drain and other drainage points, as well as the threshold parts. After the water is stored, the water will flow out from these parts. After the preliminary preparations are done, you can start waterproofing, generally around 10cm, and the test time should be at least 24-48 hours. During this period, we should pay attention to whether the water has dropped significantly, and then check whether the top of the bathroom is If there is leakage, if the test fails, the waterproof process needs to be repeated.
