How to deal with damp and moldy walls?

On some rainy or humid days, many things will be damp and moldy, or they will all be wet and damp, and so will the walls. It is also common that the walls at home will be moldy. What should I do if I find that the wall is damp and moldy?

1, toothbrush cleaning.

This method can only be used in small damp and moldy areas. You can brush off the mildew spots on the wall with a dry toothbrush and then gently wipe them with alcohol. In this way, mold can be effectively removed and regeneration can be prevented.

2, bleaching powder is clean.

As we all know, bleaching powder is used for sterilization and disinfection, and can also be used to remove mildew spots. The method is to mix bleaching powder and water according to the ratio of 1: 9: 9, and then spray it gently on the moldy place, then clean it with felt rag and clean it with clear water, which can effectively solve the moldy situation of the wall. In order to prevent mildew again, it can be repaired with mildew-proof paint.

3. Sterilizer cleaning.

In the market, there is also a sterilization agent that can be used for mold treatment. Just eat it according to the instructions of the purchased sterilization agent, which can effectively remove the problem of mildew on the wall.

4. Redo the cleaning work.

The above three methods are more suitable for the treatment of small and medium-sized damp mildew, but if it is large-scale damp mildew, I suggest knocking it out and redoing it. This is also the most thorough way to solve the problem fundamentally, but remember that we must pay attention to the external insulation of the external wall when redoing.

Many people will also feel that it is just a little moldy, and it only affects the appearance. There is no need to clean it. In fact, moldy walls are harmful to our health. The humid and moldy environment will lead to the occurrence of bacteria, and the spore powder of Pleurotus ostreatus will cause damage to the human respiratory system, causing respiratory inflammation and even skin diseases. Therefore, it cannot be ignored and must be cleaned up in time.
