Four ways to easily prevent moldy walls

Update time:2022-10-18

The phenomenon of mold on the wall not only affects the appearance of the home, but may also cause harm to personal health due to the growth and spread of mold spores.


So, what is the reason for the mold on the wall? the

The first reason: water supply, drainage pipes or heating pipes leak, causing the walls to be damp. Over time, the walls will slowly become moldy.

The second reason: external rainwater seeps into the room, causing the wall to become damp and moldy. For example, the baffles under the balcony windows (mostly made of prefabricated floor slabs, so cracks are prone to appear at the junction with the wall) and the junction of the wall have cracks, or poor sealing performance of the windows 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 indoor and outdoor, so that the water in the indoor air will condense on the wall when it is cold, causing the wall to be damp.

The fourth situation: the air humidity is too high, and the poor ventilation of the house is more likely to cause mold on the wall. For example, during the rainy season, which is common in the south, the humidity is too high. People generally close the windows and doors to avoid moisture. However, because the indoor walls have been affected by moisture, when the doors and windows are closed, effective dehumidification and ventilation are not carried out, which can easily lead to Mildew on interior walls.

If the mildew phenomenon is not very serious, you can take the following methods to control it.

Method 1: Use a dry toothbrush to brush away the mold stains, and then gently wipe with a soft cloth dipped in alcohol, which can dry the wall and prevent mold from growing.

Method 2: Add bleach (powder) to water, pour it into a water spray bottle at a ratio of 1:99, spray it on the wall with mold, wipe the wall with a rag, and then wash it off with water.

Method 3: In the case of relatively mild mold, it is enough to use 80% alcohol to wash the wall. Pay attention to ventilation when cleaning, and wear protective gloves, masks and glasses. Care should be taken to dry the walls thoroughly and to properly heat and ventilate them in order to avoid further mold growth.

Method 4: During the wet weather, open the windows as little as possible. In addition, try to keep the walls as dry as possible. In humid weather, dehumidifiers, air conditioners, and fans can be used to absorb moisture from the walls. Once moisture appears on the wall or furniture, it should be wiped off with a dry cloth immediately.

What should I do if the following situation occurs?


The above is a common severe mildew on the wall. This kind of moldy flora contains a large number of harmful molds such as Staphylococcus and Aspergillus niger, and flows in the air. Long-term exposure to inhalation can easily cause respiratory diseases and allergic symptoms, such as bronchial Inflammation, tonsillitis, hay fever, asthma, etc. It may also cause headaches, fever, and inflammation of the skin or mucous membranes in people with weakened immune systems.

For the above mildew phenomenon, the method introduced in this article cannot be used, but professionals should be hired to deal with it professionally!
