How to clean mold on the walls?

One of the great problems of homes and buildings that suffer from humidity is the appearance of mold on the walls and how difficult it is to get rid of it. However, that something is difficult does not mean that it is impossible, so from SCS Group, we will explain some tips to remove mold from the wall and enjoy a better home environment.

Causes of mold on walls

Mold is a kind of fungus that commonly appears in places with high humidity. The natural thing is that it arises through the trunk of old trees or some corner of rocks and fresh earth, but it is also very common for mold to appear on walls, causing health problems for residents and deterioration of the aesthetics of the construction.

Types of dampness and their causes

As we mentioned at the beginning, damp stains on the wall are one of the main reasons mold appears in a building. But, what is the humidity that exists? And what causes cause it? Next, we will briefly explain it to you.

Accidental dampness

This type of humidity arises because of some crack within the construction, specifically in the areas of supply pipes or drains. This causes the water to concentrate at different points and generate isolated stains on the wall and ceiling, the latter causing leaks that intensify in times of rain.

Humidity by filtration

While the accidental dampness is from some damage to the internal pipes, the filtration originates from external causes. Among the typical cases of humidity because of filtration, we can mention leaks in cracks in walls, cracks in the waterproofing of roofs, and poor execution of drainage in buildings. The consequences are white spots and mold on the walls, as well as long-term structural damage.

Moisture by capillarity

Like humidity by filtration, the absorption of water generates humidity by capillarity, but with the difference that they sucked it through microscopic pores present in the construction. This happens a lot on terraces or any porous area of ​​a building that accumulates water and is independent of wind or gravity.

Humidity because of condensation

Finally, there is condensation dampness, which is the main culprit for mold on the walls and the headache of those who try to eradicate it. We produce them due to the condensation of water vapor on a surface and which, in the absence of ventilation, causes water droplets to accumulate creating humidity.

The best products to remove mold

Mold on the walls not only affects the aesthetics of your building or home but also harms your health, causing headaches, coughs, rhinitis, and allergic diseases. Therefore, given the minimal presence of stains on your property, we recommend the best products to clean mold from the wall and live in a cleaner and healthier environment.

Apple vinegar

If you are used to season your food with apple cider vinegar, you should know that it is also an effective cleaning product to remove mold from the wall. All you have to do is spray it directly on the affected area and, incidentally, perfume the environment with the smell of apples.

Another alternative is to dilute it with water or add a few drops of essential oil in case you don’t like the strong smell of vinegar. Once the preparation is sprayed, wait a few hours and rub it with a brush to speed up the process. Just cleaning the mold off the wall with white vinegar will achieve an 82% effectiveness of stain removal.

Hydrogen peroxide

In case you don’t have apple cider vinegar, try hydrogen peroxide. The process is similar: spray it on the area affected by moisture, let it act for a few minutes, and rub it with a sponge soaked in clean water. Do not forget to dry it with a rag to remove mold from the wall.

If that’s not enough for you, try combining it with white vinegar or baking soda to apply to mold on walls. And if you eradicate it with this method, store the preparation in a dark place so that the light does not affect the quality of the hydrogen peroxide.

Sodium bicarbonate

Another good solution is baking soda, which is often used to eliminate bad odors from the house. However, you can also mix it with water to clean mold on walls by spraying it on the affected area. With this, you not only remove moisture from the wall but also leave the environment clean and without the presence of unpleasant odors.

Once the preparation is sprayed on the affected area, let it act for a few minutes. Then rub the surface with a damp sponge or cloth several times until the mold on the walls is gone.

Citrus seed extract and water

For places with poor ventilation, we recommend it to use citrus seed extract to remove mold from the wall. For that, you must spill 20 drops of the product in the water, spray it on the wall and let it act without rinsing it.
