What happened to the wall turning yellow after the rain?
After the rain, the walls turn yellow, which is usually caused by humidity. In rainy weather, the moisture on the wall surface and wall structure will increase, which will increase the indoor humidity. When the indoor humidity is more than 50%, mold and bacteria are easy to form, which makes the wall yellow. Once these molds and bacteria are formed, they will continue to multiply, resulting in unsanitary housing environment.
In addition, easy-to-clean paints and wallpapers easily fade, leading to yellowing and warping, and will constantly release harmful substances, posing a threat to human health. Therefore, it is very important to avoid the wall being too wet in rainy days and keep the indoor ventilated and dry environment. In addition, cleaning walls and walls regularly and removing accumulated dust and dirt are also the key to keeping walls dry and clean. If the room is too humid, consider installing a dehumidifier or an air purifier to keep the indoor air quality and the walls clean.
