Why does the wall ooze water and how to deal with it?

Miss Zhang's Problems in Lugong New Town

Recently, there has been water seepage in the house, mainly on the wall adjacent to the bathroom and kitchen. Water seepage is very serious, but it can be clearly seen that the wall is soaked by water. What is the reason and the solution?

Supervising and answering questions

In the process of home decoration, improper construction may not be a problem at first, but various problems will soon appear. For example, you will find black spots on wet walls, or water leakage on the top and walls, and some even have moldy hair. These phenomena have brought a lot of inconvenience to family life, but many people don't know what caused this situation and how to check it. Just miss Zhang's family also encountered the same problem, so I will analyze it for you today.

First, why does the wall leak water?

1, without insulation layer:

In the past, many residential walls had no insulation layer. In winter, the temperature difference between indoor and outdoor is large, so it is cold outside the wall and hot inside. Because of the high temperature of the inner wall, condensed water will form on the wall, which will lead to the wall being wet, and it is the whole wall. This kind of situation usually only occurs in winter, but it will be fine in summer, but the sequela is that many ugly mildew spots will be left, which will affect the beauty of the wall.

2, water pipe leakage through the wall:

The water leakage of the pre-embedded water pipe in the wall causes the wall to be wet. Generally, this happens near the toilet, or on the top of the house, or on the wall. Generally, there is leakage at the joint of embedded water pipes, including whether there is leakage in the water pipes in the walls at home and upstairs, and water seeps into the partition wall.

3. Poor waterproof measures:

(1) The waterproof of the ground upstairs is not done well, which leads to water leakage on the wall. The waterproof of the upstairs floor is not done well, and the bathroom next door or the bathroom next door upstairs is not waterproof well. Once there is water in the bathroom, it will slowly seep down.

(2) The joint between the upstairs water pipe and the ground is not waterproof, and there is a possibility of water seepage near the pipe. Water flows down the water pipe, leading to water seepage on the roof.

4. Improper painting:

When painting the wall, the first time the wall paint didn't dry completely, so we started to paint it again, and the water vapor in the wall didn't evaporate, which caused the wall to be wet.

Second, how to deal with wall seepage?

1. Replace or repair the water pipe directly: If it is caused by the water pipe, you can replace the water pipe or temporarily repair it with the special tape for repairing the water pipe first. The specific operation method is: first close the valve and cut off the water supply, then open the faucet to a suitable position to release most of the pressure in the water pipe, and then tie the leaking part with special adhesive tape or seal it with epoxy resin glue.

2. Contact the hotel:

Any problems involving the external wall should be reported to the property, and the property should contact the engineering department for maintenance.

3, waterproof coating:

Owners with water leakage at home can buy waterproof coating for plugging and paint the bathroom walls and floors themselves. The best way is to ask the decoration workers to solve it, which is more professional and effective. Or waterproof it again, it will be a little troublesome.

Such a situation as Miss Zhang's is actually very common in daily life. Many owners will complain about this problem. It is suggested that Miss Zhang first find out what causes the wall seepage in her home, and then start to deal with it for this reason.
