If you want the house to be well installed, you must first do a good job of waterproofing. Many people do not know the meaning of waterproof, how on earth workers construction, until the completion of check-in, only to find that the waterproof is not done, downstairs neighbors knock on the door every day to complain, especially in the bath. So, when we are in the construction of workers, we should know what place to do waterproof? What kind of standards are they?
The bathroom is a relatively humid zone, the ground will often have water, so the waterproof bathroom is sure to be strictly implemented, to ensure that there is no mistake. After the completion of waterproof need to carry out closed water test. Let’s take a look at the common problems of waterproofing.
First, the choice of waterproof materials
There are many kinds of waterproof materials, and sanitary ware because of the small area, a lot of Yin and Yang Angle, through the floor tube is also more, so you need to choose good adhesive, elastic waterproof material.
Ii. Construction process
1. First of all, the basic treatment should be carried out. Generally, the floating dust on the base surface should be cleaned first, and the cement caked and loose base layer should be cleaned first. The root of the pipe, drainage holes, Yin and Yang Angle, wall after the water and electricity transformation left holes for processing, Yin and Yang Angle because of the circular arc, if there are uneven, cracked parts, need to be repaired, leveling.
2 again is to understand the proportion of the deployment of waterproof material knowledge, if the proportion of the material is not right, will not achieve the original effect.
3. We should brush waterproof materials from top to bottom, the wall after the ground. It needs to be brushed twice, and the time distance between the first and the second is about 4-8 hours. Remember after the first brush must be the premise of the first waterproof layer is not stick to the hand, and before and after two brushes were crossed.
4. Sometimes the choice of waterproof material is different, the number of passes is different, but generally in 2-3 times.
5. Generally, when we paint waterproof materials, the waterproof height of the shower wall is 180cm, while the non-shower wall should not be less than 30cm. But in order to better play a waterproof role, it is best to unify the height of 180cm, and for the reconstruction of light body wall and self-built light body wall, it is recommended to unify the brush to the top.
6. The thickness of the coating waterproof layer must be 1.5mm thick according to the national acceptance specification.
The above waterproof construction steps, please be sure to follow the standard construction, no mistake.
Finish the steps of bathroom waterproof, and then say those places need to be careful to do waterproof treatment.
Sanitary ware, often the most prone to water leakage is: the location of the floor drain, small water pipes, floor connecting parts and toilet pipe parts. So these places should be attached importance to the construction, other places can brush 2 times waterproof, but these places are best to brush several times. In addition, the most leakage place is under the door stone, so we need to do a zone under the door stone in advance, waterproof needs to roll to the zone, so as to form a basin, to achieve the role of water storage, water retention.
Finally, let’s talk about the closed water test after the bathroom waterproof, this is the most critical step.
When we do the closed water test, we must wait for the waterproof material to dry out before we do it. Before closing the water, we need to plug the drainage points such as the floor drain, and the threshold part should also be blocked. After placing the water storage, the water flows out from these parts. After the preparation is done, you can start waterproof, generally about 10cm, the test time should be at least within 24-48 hours, we should pay attention to in this period of time, there is no obvious drop in water, and then check whether there is leakage at the top of the bathroom, if the test is not qualified, you need to go through the waterproof process again.
