How to get rid of mold on the ceiling in the bathroom?

Quite often you have to deal with such an unpleasant phenomenon as black spots on the ceiling in the bathroom - this is mold . In addition to spoiling the appearance of the room, mold is harmful to human health.

Its waste products are toxic and after inhalation, a person may develop allergic reactions and feel worse. Although it is difficult to fight mold, it must be done and it is possible to cope with it.

Dangers of each type

There are always mold spores in the air, but they begin to develop only under favorable conditions. It can appear on concrete, brick and other surfaces and be black, green or blue.

Types of mold:

• black mold , its type depends on the stage of development;
• white mold on walls is rare, it is often confused with efflorescence, but if you pick it up in your hands, it will knead and the efflorescence will crumble;
• blue , it affects wooden surfaces;
• actinomycetes are a cross between algae and fungi; they also infect wooden objects;

If we talk about a person’s reaction to mold, it can be divided into the following groups:

• Allergic , it is especially dangerous for people with diseases of the respiratory system and is often the cause of allergic rhinitis.
• Pathogenic , it can cause various diseases, healthy people with strong immunity usually cope with it, but children, the elderly and people with weak immunity can develop diseases such as pneumonia, bronchitis, etc. It forms gray and black colonies.
• Toxic species can cause serious complications, and even death. Problems caused by such mold can be in the form of irritation, other symptoms and even lead to the development of cancer.

Mold spores can enter the human body through the air, during breathing, through the skin or through food.

The most common diseases that arise from exposure to mold are asthma, pneumonia, other respiratory diseases, upset stomach, various skin rashes, and headaches.

With prolonged exposure to pathogenic species, a person may develop internal bleeding, kidney, liver, and lung diseases. When mold enters the human body, it is called mycosis; for diagnosis, it is necessary to contact a specialized laboratory.

What is mold

Dark spots, gray or black, that appear on ceilings are a type of fungus that actively reproduces by spores. This is precisely why it is dangerous - spores penetrate almost everywhere, not leaving a single room with their attention.

But fungi begin to develop at humidity levels exceeding 95%. This does not mean that if the humidity in the apartment is a little less, then there will be no fungus - its spores are found almost everywhere.

There are many varieties of mold, and most of them are very dangerous. You can see or simply detect such a neighbor by the musty smell that appears and multi-colored spots on the walls or ceiling.

For the most part, residents of standard houses encounter fungal stains in their apartments that are greenish, gray or black in color. Although, the color range of fungi is quite extensive, and one should not be surprised at the appearance of yellow or reddish spots of the fungus.

Causes of mold

For mold to begin to grow in the bathroom, the following conditions must exist:

1. presence of spores in the air;
2. presence of a nutrient medium;
3. favorable climate: high humidity, temperature more than 15 degrees, poor ventilation, uneven heating and freezing of walls.

Since we cannot influence the appearance of spores in the air and the presence of a breeding ground for mold, it turns out that the most effective way to combat it is to create effective ventilation and a constant temperature in the room.

The main causes of mold in the bathroom:

• poor ventilation, if it is not possible to install an effective exhaust hood in the bathroom ceiling, you need to ventilate the bathroom more often;
• the presence of moisture due to problems with water supply and sewerage;
• with poor waterproofing, moisture can enter the house through the foundation;
• heat loss in the corners of the room due to poor wall insulation;
• freezing of walls;
• improper operation of the drainage system.

What to do

As soon as you discover that your apartment has an area affected by such a scourge on any of the surfaces, you should take the following actions:

• Determine the type of fungus. This can be done by studying the color of the stain that appears.
• Find out the main reasons for its appearance. This can be either high humidity or simple freezing of walls or ceilings during the cold season.
• Choose a method to eliminate the scourge, focusing on a specific type of lesion and selecting the appropriate chemicals.
• Eliminate all factors that caused the phenomenon.
• Remove the formation.
• Treat the surface with special means.

In short, this is what the general scheme for dealing with an unwanted “guest” will look like. Next, we’ll talk in more detail about ways to combat damage to surfaces and the means used for this.

Elimination of causes

Before you start fighting mold, you first need to eliminate the reasons that led to its development.
If this is not done, then no modern or folk remedies will help you get rid of the fungus, since after a while it will appear again. Eliminating the causes of the fungus consists of the following steps:

1. It is necessary to get rid of the source of constant humidity , that is, it is necessary to repair the sewerage and water supply systems if they have leaks.
2. Creation of a normal ventilation system in the room . To do this, you need to check the ventilation duct, which may be closed, so it needs to be cleaned. One way to ventilate a bathroom is to install a breather, a compact supply ventilation system that is mounted on the wall and provides the room with fresh air. If the room has a plastic window, it is recommended to install ventilation ducts in it.
3. to maintain a constant temperature in the bathroom to avoid large temperature changes. To do this, it is necessary to carry out high-quality insulation of the walls, install a heated towel rail, and install a heated floor under the tiles.

Some people believe that air conditioning will help get rid of mold, but this is not true, it helps reduce the humidity and temperature in the room, but does not supply fresh air, so it only drives mold spores around the room. There must be an effective ventilation system that will change the air in the room.
