Mold occurs not only on elite cheeses, but also appears on the walls. And if in the first case white cheese mold is considered noble, then the black bloom on the walls upsets the owners of the house. Small dark spots on the wallpaper grow quickly and very soon become black and green streaks covering the ceiling and even upholstered furniture. Moreover, the defeat is so deeply eaten that sometimes it is simply impossible to remove it. We will learn how to get rid of the existing problem and what measures must be taken.
The reason for the appearance of fungus on the walls
If you do not know the reason for the appearance of mold on the wallpaper, then it will never be possible to completely localize it. There are two main reasons: dampness and poor ventilation. The industrial reasons for the spread of fungal spores are as follows.
- The design of reinforced-plastic windows does not imply an inflow of fresh air. If the room is not regularly ventilated and there is no special forced ventilation system in the windows, then the fungus is provided.
- Above your dwelling is only a roof that is leaking. In a panel house, moisture will also spread along the joints along the lower floors.
- In apartments on the ground floor, the lesion begins at the joints of the walls, and then the mold penetrates under the wallpaper. There is a basement under the apartment, which is often heated and moisture accumulates in it.
- After the completion of the repair and finishing work, residual moisture remains in the room. The repairs must be completed before autumn or wallpaper must be glued when the centralized heating is working.
- Poor waterproofing of interpanel joints and external walls. Mold appears in autumn when there is no heating and the weather is cold and rainy. It is enough to freeze one of the walls to form condensation.
- The first plaque appeared in the shower room, where it is humid, warm and poorly ventilated. With simultaneous heat and moisture, you need to have powerful ventilation.
- Faulty plumbing: leaking pipes of cold and hot water or heating.
- There are many indoor plants in the room, which are often watered, which causes high humidity.
- The furniture stands firmly against the wall, which prevents good air circulation. This is especially true for external walls.
- The neighbors on the top floor flooded your apartment and the water soaked all the walls with dampness.
As a result, in private houses, the main reason is insufficient heating and poor air circulation, and in multi-storey apartments the problem of fungus comes from the outside and also a poor ventilation regime.
Why is fungus on the walls harmful to human health?
The mold that develops can vary.
- Green. It is most often encountered and you can not be afraid of it. It will quickly disappear if handled correctly.
- Dark green. Problematic, but if it is immediately identified and immediately removed, then it will not bring much harm. It is removed simply.
- White (like fluff). It spreads quickly and imperceptibly, affecting the entire apartment. You can't hesitate with her, because she is very dangerous. It should be removed carefully with gloves and a respirator.
- Black. She is the most dangerous. It grows quickly and is difficult to remove. It must be treated with chemical mixtures, and at the end of the work, preventive measures should be carried out so that the plaque does not settle again.
At the same time, please note that if any type of mold affects more than 20% of the area, then this is a massive contamination of the room. It becomes unusable and dangerous to live in. The harm from the fungus to humans is as follows:
- Skin problems, allergies, headaches, conjunctivitis, suffocating cough, stomatitis.
- Spores of moldy fungi penetrate into the body, settle on the mucous membranes of the respiratory system, and chronic rhinitis and pulmonary diseases appear.
