How to deal with mold on the wall

Rooms that are not occupied for a long time or have excessive humidity or spring tides may cause mold to grow on the walls. Once it gets moldy, it is not suitable for living. If you live in such an environment, you are very likely to get sick and your health will be affected. So if you feel the room has a musty smell, it is best to deal with it in time. So how should we effectively deal with walls that have already grown mold? Can the room still be lived in normally after being treated? In addition, how can we avoid this situation in daily life?

1 When mildew spots appear on the wall, you can first use a (dry) toothbrush to brush away the mildew stains, and then gently wipe it with a soft cloth dipped in alcohol. This can dry the wall and prevent the growth of mildew.

2 Add bleach (powder) and water in a ratio of 1:99 into a spray bottle and spray it on the moldy wall to immediately solve the moldy problem. Wipe the wall with a rag; then wash it with clean water. After the wall is dry, apply anti-mildew paint to prevent moisture for a long time. In addition, there is a convenient household waterproof repair agent on the market. You only need to spray it on the gaps in the leaking walls and floors like an insecticide. It is very convenient to use.

3 If the mold is not too serious, it is sufficient to use 80% alcohol to wash the walls. Pay attention to ventilation when cleaning and wear protective gloves, masks and glasses. To prevent mold from forming again, care should be taken to thoroughly dry the walls, eliminate the causes of mold, and provide proper heating and ventilation.

4. During humid weather, try to open windows as little as possible. In addition, try to keep the walls dry. In humid weather, you can use a dehumidifier, air conditioner, or fan to absorb moisture from the walls. Once moisture appears on the walls or furniture, it should be wiped off immediately with a dry cloth.

Causes of wall mold

The first reason: leakage in the water supply, drainage or heating pipes causes the walls to become damp, and over time the walls will become moldy.

The second reason: external rainwater seeps into the room, causing the walls to become damp. Cracks in the baffle plate under the balcony window (mostly made of prefabricated floor slabs, so cracks are prone to appear at the junction with the wall) or poor sealing performance of the window may cause external rainwater to seep into the room.

The third situation: the wall insulation is not done well, resulting in a large temperature difference between indoors and outdoors. In this way, the water in the indoor air will condense on the wall when it gets cold, causing the wall to be damp.
