How to deal with wall seepage

1, the problem of wall seepage, first of all, we need to find the reason, which may be caused by the rupture of water pipes in the wall. Generally speaking, this problem is most likely to occur in the bathroom or roof. Need to determine where the water pipe is broken, and then dig the foundation.

Then plug the water pipe, for example, plug the joint, or directly replace the new pipe, so that the problem can be solved once and for all, and finally the wall will be restored to its original state.

2. If it is the joint between the ground and the water pipe, the waterproof layer is not in place or the waterproof layer has failed, which will also lead to water accumulation and slowly penetrate into the wall. In this case, it is necessary to waterproof the wall again, remove the putty waterproof layer and cement mortar on the wall, and then spread a layer of steel wire mesh on the wall to prevent cracking.

Next, add some expansion agent into the cement mortar and repair it in 2~3 times. When it is dry, paint the wall with primer and topcoat. It can bring waterproof effect when it is dry.

Second, what should I do if the wall falls off?

1. If peeling and peeling appear on the wall, it means that the water seepage is very serious, which may be caused by direct sunlight, resulting in fading and peeling of the wall. These are all caused by the relatively large temperature difference between indoor and outdoor, and the surface will be moldy and black in the later period.

2. For such a wall, we can choose the repair method. First of all, we should strengthen the base of the wall, tear down all the peeling walls, then paint the walls and rebuild the basement. Leveling with gypsum, repairing with gypsum, sticking grid cloth on the surface, and then brushing primer and topcoat can play a decorative role.
