What should I do if there is water seepage on the exterior wall around the bathroom

There are two types of water seepage in the bathroom wall:

1. One is that the water leakage on the upper floor seeps into the lower wall, which is not caused by its own reasons. The treatment method is to open the bathroom ceiling to see if the upper layer is leaking to the lower floor. If it is water seepage on the lower wall caused by water leakage on the upper floor, you first find the owner of the upper floor and negotiate with the owner of the upper floor to solve the problem.

2. The other is that the waterproofing of the house is not complete, resulting in water accumulation on the wall penetrating into the wall. If the waterproofing is not done well in your own decoration, then you need to re-waterproof the bathroom.

How to prevent a leak in the bathroom:

1. Try not to damage the original waterproof layer.

Try not to damage the original waterproof layer, the ground of the newly delivered building is generally made of waterproof layer, so there is no leakage without destroying the original waterproof layer. However, the waterproof layer is easy to be damaged when renovating the ground, and if it is accidentally damaged, it should be repaired in time to avoid leaving hidden dangers.

2. Resurface the floor tiles to make the ground waterproof.

If you need to replace the original floor tiles in the bathroom, after chiseling off the original floor tiles, you must first level the ground with cement mortar and then do waterproof treatment. This avoids leakage due to uneven thickness of the waterproofing coating. Before waterproofing, be sure to clean the ground and paint it 2 to 3 times with polyurethane waterproof paint.

3. Be sure to do wall waterproofing.

Water splashes on adjacent walls during bathroom bathing, so be sure to waterproof the walls before laying wall tiles. Generally, the wall should be waterproofed with a height of 30 cm in waterproofing treatment, but for non-load-bearing light walls, the entire wall should be waterproofed, at least meter high. At the same time, pay attention to the waterproofing of the wall adjacent to the shower position should also be meters high.

If a bathtub is used, the height of the waterproofing paint on the wall adjacent to the bathtub should also be higher than the upper edge of the bathtub.

The joints between the wall and the ground and the joints of the pipes between the water and the water are the most problem-prone places, and the workers must be urged to deal with these edges and corners, and the waterproof coating must be applied in place.

4. The groove of the water pipe in the wall is waterproof.

The groove of the water pipe in the wall should also be waterproof, and the waterproof layer around the hole must be carefully constructed when the pipe, floor drain, etc. pass through the floor slab during the construction process. The buried water pipe in the wall should be reasonably arranged, and the water pipe should be made with a groove larger than the pipe diameter, and the plastering in the groove should be smooth, and then the groove should be brushed with polyurethane waterproof coating.

Both manufacturers are large manufacturers, the key is whether they buy the products of regular manufacturers, and whether the construction is in place, generally with coatings, especially the bathroom must choose environmentally friendly, do not be less than three times when painting, the wall height is 30-50cm, there is a shower, and the non-load-bearing wall is to do 180cm.

It doesn't matter what material is used, the key is only the thickness, do not destroy a layer of film on the surface, and at least 30-60 cm high.

Yes, both waterproof coatings are good, and they are both lip cards.

There is no strict statement on the order of operations. No problem.

Note: I don't know if there is any flexible one in the two. Preferably one that is flexible. (crack resistant).

1.Pressure the water pipe first, and then the hot water pipe should also be used to prove that the water pipe is fine.

2.It is best to have a partition between the shower and the toilet, and the water vapor acts directly on the door and wall when taking a bath, so it is best to make a partition, and at worst to make a shower curtain;

3.Then check whether the floor tiles have backflow water, if there is backflow, then the water has accumulated in the door for a long time, and seeps into the wall and the floor outside the bathroom along the marble gap;

3.If there is no backflow of water, in order to avoid a big fight, first try to scratch off the original hook on the bathroom floor wall, and use a good waterproof grout to scratch it again.

Be sure to tick carefully to plug the loopholes that may return to the bottom and walls of the dwelling, and if it doesn't work, then knock on the wall.

1.It's okay to do it 2 or 3 times at home, 2It depends on whether the structure of your home is good or not, generally speaking, it is okay.

3.I'm super ah, use such a good ah, what do you want to do?
