2. There is a simple way to deal with mold. You can buy a special waterproof mending agent directly in the market and spray it gently on the wet and leaking wall. Or make a bottle of waterproof spray, the ratio of bleach to water is 1: 99, pour it into the spray bottle and spray it on the moldy wall to solve the moldy situation. Then gently wipe the wall with a soft cloth, clean it with clear water, and brush a layer of mildew-proof paint after the wall is dry, which can prevent the wall from being damp and moldy for a long time.
3. If there are too many molds on the wall, you need to use 80% alcohol to clean the wall. Be sure to ventilate when cleaning, and wear protective gloves, eyes and masks. In order to prevent the wall from moldy again, the wall must be completely dry, and the heating can be turned on for drying.
In order to avoid moldy walls, try not to open windows in wet weather. You can also use fans, air coolers and dehumidifiers to absorb water from the walls. If water drops appear on the wall, be sure to wipe them with a dry rag in time.
