How to Remove Mold from Drywall?

Our home, the place where we spend most of our time, has to have ideal conditions so that we can live and perform all day-to-day activities in it. Not only does it have to be a space that we enjoy, but we also have to take into account some minimum characteristics that allow our health and wellbeing to be maintained appropriately.

At certain times, no matter how much we take care of our house and try to avoid the appearance of any type of organism that could affect it, the plagues exist and can grow everywhere, even though we put measures against it. Not only insects such as ants or termites can affect the safety of our home. Another type of less showy and silent organisms can make their appearance without us realizing the real danger they can pose to our health and that of those who live with us. An example is a black mold. That’s why an unCOMO explains why black mold comes out on the walls.

What is black mold

Mold, in general, is found in common in multiple places of nature, as it is a first organism to break down and provide nutrients to the earth, so it is necessary for life. But it is true that inside houses and buildings can cause effects that we do not want. Different types of mold can grow in homes, and one of the most common is what is referred to colloquially as “black mold,” also known as Stachybotrys Atra. Many consider it extremely dangerous for the health of people, but it is true that it is not far from the effect that the rest of the molds can have.

How is this type of mold identified? It is very simple. First, pay attention to your nose and if you have noticed a strange and unpleasant smell in some area of the house, it is probably due to the appearance of this black mold on some wall. When you have it located, see the color of it. The most normal thing is that it is a greenish-black or brownish color, but sometimes it may appear more greenish. The last thing you have to take into account to identify it is its texture. Avoid touching it directly with the skin, use a towel or a paper to discover if it has a viscous texture, which is produced by the moisture under this first layer that covers it.

Why there is black mold on the walls and how to clean it

Black mold only grows and develops under special conditions. There must be certain factors that facilitate and promote their growth.

Humidity is the main trigger for mold spores to sit in the ideal environment to settle and multiply. Therefore, you have to be especially careful if you live in places where the degree of humidity is quite high, such as near the coast.

It is essential to maintain adequate ventilation of the house, as it will help prevent the humidity level from increasing even more inside our home. If we do not, the moisture-laden air stagnates and is a perfect place for the growth of black mold on the walls and other corners of the home. This must be taken into account especially in rooms such as the bathroom or the kitchen, where there are usually wet surfaces.

Extreme caution should also be taken in case of leaks in the water pipes behind the walls. If this situation is maintained, even for a short time, the most common is that black mold appears in the surroundings due to moisture in the wall.

Another cause of mold inside the houses is the custom of hanging wet clothes inside the rooms. It is highly recommended to dry clothes on the terrace, to avoid water condensation and increased humidity inside your home. If this is not possible, since you do not have a terrace, get a clothesline and place it near a large open window to facilitate ventilation and prevent moisture from accumulating.

To clean the black mold from the walls, you will first have to remove as much moisture as possible: cut the water, fix the pipes and ventilate the room. Then you will have to clean with bleach and when all the mold has been removed, you can repaint the wall. 

Tips to avoid black mold on the walls of the house

To prevent the appearance of black mold on the walls of our home we can take some precautions, such as the following:

  • Maintain good ventilation at home.
  • Act quickly in the event of a water leak, to avoid puddling and humidity.
  • Extreme precautions and monitor the appearance of mold in case of leaks in pipes.
  • Lay clothes outside or near a window with good ventilation.
  • If we live in an area with a high level of humidity, we can get a dehumidifier, as long as it can maintain a level of less than 55% humidity, since some types of mold only need this percentage to grow.
