How to deal with the water seepage on the wall outside the rain

Before dealing with the problem of wall water seepage in rainy days, we must first find out the reason of water seepage. Generally speaking, the causes of water seepage in external walls may include:

1. Water seepage caused by aging of brick wall or paint;

2. The surface of brick wall is polluted by dust or dirt, which affects its water permeability;

3. The joint between the external wall and the room is not completely sealed, resulting in water infiltration into the room;

4. Excessive exposure or wind and rain on the external wall leads to water seepage.

Next, we can take the following measures to deal with the problem of external wall seepage:

1. Repaint or replace the brick wall to repair the aging or wear of the brick wall or paint;

2. The water permeability is improved by cleaning the dirt and dust on the surface of the external wall;

3. In view of the problem that the joints are not sealed, sealing materials can be used to fill the gaps;

4. Regularly check the condition of the external wall and timely repair the damage caused by weather and other factors.

In a word, when dealing with the problem of water seepage on the external wall of rainwater, we must find out the causes of water seepage and take corresponding measures according to the actual situation. This can ensure that the integrity of the external wall can be maintained and reduce the potential safety hazards caused by water seepage.
