Why does the house get moldy

Why did it get moldy? A good thing got moldy. I am not happy at all. Things that were originally bought to be eaten have now become waste, and it is emphasized that waste is shameful. Even in such an indestructible house, you will occasionally find some ugly spots on it. How could a good house get moldy? You have only heard of food getting moldy. Why are you messing with the house? Aren't you just making a fuss? There must be reasons for mold in a house. The most typical factor is that it is too humid. There are some other reasons that I will introduce to you one by one below.

1. Leakage in the drainage pipe or heating pipe causes the wall to become damp, and over time, the wall will become moldy.

2. 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.

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

The house is moldy and has small mold spots. What should we do?

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 will 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. What can we do in daily life to prevent mold on walls?

1. Open windows frequently for ventilation or turn on fans to keep indoor air flowing.

2. Purchase indoor desiccant and use it indoors to effectively remove indoor moisture. After the effective ingredients of the desiccant are used up, it needs to be replaced in time.

3. The best way to prevent mold from growing on the walls is to prevent condensation on the walls. In the northern region, when the room temperature is 18 degrees Celsius and the relative humidity is 60%, any object below 10.1 degrees Celsius will condense.

4. There are three reasons for condensation on the wall: design, construction, and use. The design reasons include: although the walls meet the moisture retention requirements, the beams, slabs and columns have not been treated for moisture retention; the heating technical measures are not adequate and the radiators are improperly arranged; the convex corners and special-shaped columns on the windward side of the exterior wall do not have a thickened moisture retention layer, resulting in the thermal insulation effect not meeting the standards. The construction reasons include: the insulation material did not reach the thickness specified in the design; strong cracking and ventilation; and no moisture-proof sealing treatment was done between the joints between doors, windows and walls.

Why does it get moldy? Why? He said arrogantly, "I just like it." At this point we can only helplessly laugh. In fact, as long as we take reasonable preservation measures, it may not get moldy and will not be wasted. There are reasons for mold. An item may get moldy without us noticing. What we need to do is to prevent the next item from having the same experience.
