When the wall is moldy, you can refer to some of the following ways to handle it.

Moldy walls not only affect the aesthetics but are also bad for the health of family members. There are many different reasons that lead to moldy walls. Some common causes are as follows:

- Walls are wet for a long time, located in a humid climate all year round.

- Not using waterproof paint.

- Using poor quality construction materials, poor construction techniques, mixing mortar in the wrong proportions.

- Leaking water pipes.

- The house has been built for a long time, the waterproofing ability has deteriorated.

Use alcohol

Alcohol is a very good disinfectant. You can use it to remove mold and clean bacteria. In case the moldy wall is not too large, you can use alcohol to wipe until the mold stains fade. Note, when using alcohol, you need to be careful, do not leave it near a fire source because alcohol is very flammable.

Use vinegar and baking soda

Baking soda and vinegar are easy-to-find ingredients that are safe for the user's health. Combining these two together can help you remove mold on the wall effectively.

Mix baking soda and vinegar and apply evenly to the moldy area. Leave this mixture on the wall for about 10-15 minutes. You can use a brush to scrub gently to make the mold removal process more effective. Then, wipe it with a towel and clean water.

Use bleach

Javel is a common bleach that can be easily purchased at grocery stores and supermarkets. You can use this ingredient to remove mold on the wall more effectively than natural ingredients. However, because javel is a chemical, when using it, you need to wear gloves and a mask to avoid direct contact.

Mix bleach with water in a ratio of 1 bleach: 2 water.

Use a roller dipped in the bleach mixture and rub evenly on the moldy wall. Leave it like that for 15-20 minutes. Use a brush to scrub gently to clean the mold. Use clean water to wipe the entire wall. During the process, remember to open the doors to let the air circulate, helping the chemical smell evaporate quickly.

In case the wall is seriously moldy, in a large area, you should choose another treatment method. You can repaint the entire moldy wall to ensure aesthetics as well as prevent mold more effectively.

In addition, it is necessary to find out the cause of the moldy wall. If it is due to a leaking water pipe, timely remedial measures are needed.

If the moldy wall is due to high humidity, you can also install a dehumidifier in the house to remove excess moisture, which is good for human health and limits mold on the wall and other items in the house.
