    Relative to the leakage part of the inner wall, the outer wall extends at least one meter to the surrounding area, and the cold wall should be extended to the range of 1 meter each of the two adjacent warm walls, and the construction area is twice the construction area of the inner wall, so as to ensure the construction quality.

Its specific construction steps: (1) the base is cleaned up, and the attachments are wiped off; (2) Spray a special spraying solution for strong mold removal to kill the surface mold; (3) Paint a special anti-mildew latex paint; Hint:

    The causes of water seepage and mildew in the walls are:

    1. There is no insulation layer on the wall: in the past, the wall of many houses did not have an insulation layer, in winter, the temperature difference between the surface and the inside of the room was large, so the wall was cold outside and hot inside, and the inner wall surface would produce condensation because of the high temperature, resulting in the wall being wet, and it was the whole wall, such a situation was usually only presented in winter, and it would be good in summer, but the sequelae was that it would leave a lot of ugly mildew, which would affect the beauty of the wall.

    2. Leakage of water pipes in the wall: The leakage of the embedded water pipes in the wall caused by the lack of good connection of water pipes, the use of inferior water pipes, and the lack of pressure test of water pipes is easy to cause water seepage in the wall, which mostly occurs near the bathroom, the roof of the house or the wall.

    3. Waterproof measures are not done: the wall waterproofing of the neighbor's bathroom next door is not done, the ground waterproofing of the upstairs neighbor's bathroom is not done, the waterproofing of the combination of the upstairs water pipe and the ground is not done, and the waterproofing of the roof or wall and ground is not done, etc., which may lead to the occurrence of leakage.

    4. There are cracks or holes in the structure of the house: there are cracks in the structure of the house, there are gaps between the windows and the structure, and the air-conditioning holes are not tightly sealed, and the rainwater will seep into the wall along the cracks under the action of the wind, and the water vapor contained in the wall for a long time cannot evaporate in time, and the wall will become moldy.

    Solve the root cause of water seepage first, and the rest will be easy to deal with, otherwise, if you deal with the moldy place, if the water leakage is not solved, it will become moldy again. Once the water seepage problem is solved, it is time to remove the mold with a special wall mold remover and spray it on the area where the mold grows.
