A lot of articles have been written about fungus on the walls. Almost all media outlets describe methods for solving this problem. The enormous dangers of finding such microorganisms in a residential area have long been announced by specialist scientists. In many apartments, a black fungus appears on the walls. It is mainly formed in the bathroom or in the kitchen, that is, in places with high humidity. But in some apartments, this infection extends to all living rooms. "Black mold" scientists call the fungus Aspergillus niger. It can form in the seams between the tiles or sprout under the wallpaper. The fungus not only worsens the appearance of the apartment, but also smells very unpleasant. People begin to bring him to the walls only when he is fully settled in their home, so the fight with him becomes a real problem.
The fungus on the walls, like all its "relatives", is spread with the help of thin filaments of mycelium - mycelium, which can penetrate deep into the pores of tiles, into wood, plaster or concrete. Black plaque on the wall is ready-made spores of the fungus, which can spread throughout the apartment with the slightest draft. In such a situation, the process of removing it will be much more complicated. At a fast pace, the fungus grows on the walls with a humidity in the room of more than 70%. He likes dark places and a temperature of about 20ºC. Therefore, the bathroom is an ideal place for the development of this fungus.
Harm to health
In addition to the unpleasant odor, the fungus causes noticeable harm to health. If it is not removed on time, then it can lead to a general weakening of the body and cause infectious diseases and even cancer. It has already been scientifically proven that the fungus on the walls of the apartment can cause aspergillosis and various other mycoses, can cause the development of allergic reactions. If you do not withdraw it in time, then it can cause significant harm to health, and especially to people of advanced age, children and patients with asthma.
Prevention methods
There are a great many ways of how to remove the fungus on the walls, but it is better to try to prevent its occurrence. First of all, it is worthwhile to establish ventilation in the living room. It is believed that with good drawing, the notebook sheet should be attracted to the ventilation hole. If this does not happen, then it is worth doing channel cleaning. It does not hurt to install an electric fan in the hood. High humidity will help to cope with underfloor heating, elimination of all leaks and foam rubber pipe insulation.
Fungus on the walls. How to fight?
If you still allowed the appearance of the fungus, then you can’t do with half measures alone. It will be necessary to clean the wall to a concrete base, to erase the fungus. It should be well cleaned and thoroughly dried. After that, you need to carefully treat all problem areas with a blowtorch to completely kill the fungus and its mycelium. A solution of copper sulfate 10% gives almost the same effect, which must be applied to prepared areas. Another composition suitable for such purposes can be made by dissolving 250 ml of a 40% formalin solution in 10 liters of water. Use special tools. Fortunately, the modern market is replete with these substances.
Removing the fungus from the wall is not all. It will be necessary to add antifungal agents to the finish. Do this before leveling the walls or putty. If you do not fulfill all these conditions during the repair, then after a few weeks the fungus will again make itself felt.
