Why does the wall seep?

Why does the wall seep?

1, no insulation

In the past, many houses had no insulating layer in the wall. In winter, the temperature difference between indoor and outdoor was large. Therefore, the wall was cold and hot inside. The inner wall had high temperature, so the condensate water formed on the wall caused the wall to be damp, and it was full. Facing the wall, this situation generally only occurs in the winter, and it will be good in the summer, but the aftereffect is that it will leave a lot of unsightly mildew and affect the appearance of the wall.

2. Leakage of water pipes in the wall

Walls caused by leakage of embedded pipes in the wall are generally damp. Generally, such conditions occur near the bathroom, or on the top of the house, or on the wall surface. Generally, there are leaks in the buried pipe joints. Whether the water pipes in the walls of the home and the upstairs are leaky, the water in the partition wall infiltrates.

3, waterproof measures are not good

The waterproof construction of the ground floor on the 1st floor did not do a good job of leaking the wall. The waterproof of the ground upstairs was not done well. It also included the waterproof of the toilet next door or the bathroom of the bathroom next door upstairs. If there is water in the bathroom, It will slowly penetrate.

On the 2nd floor, there was no waterproofing at the junction of the water pipe and the ground. It is very likely that water seepage occurred near the pipe. The water ran down the pipe and caused the roof to seep.

4, improper paint

In the paint project, when the wall was painted, the first time the wall paint did not dry out, it began to paint the wall paint the next time. The water vapor in the wall failed to evaporate, resulting in the dampness of the wall.

Once the water seepage problem occurs on the wall, it may lead to the appearance of wall cracking and mildew on the wall, which brings inconvenience to the daily home life. Therefore, when water seepage occurs on the wall, we should take measures to deal with it immediately.
