Mold is a living organism capable of producing substances that are harmful to human health. In favorable conditions, its spores grow rather quickly, gradually spreading over the entire accessible surface. It is extremely dangerous to live in such an apartment: immunity suffers and allergic reactions may become more frequent.

A simple way to protect yourself from such problems is to timely prevent the spread of harmful microorganisms. In these cases, the affected walls or ceiling are treated with special antifungal primers.

Reasons for the appearance

Why is there mold in some apartments and not in others? The answer is simple - spores can be in the air around, but getting into a favorable environment, they settle on surfaces and begin to multiply. There are a number of reasons why fungus can appear in any home:

  • poor ventilation of the premises;
  • high level of air humidity (which is why the main places of mold damage are the walls of kitchens and bathrooms);
  • water supply or sewage leakage;
  • rise of capillary moisture from the foundation up the walls;
  • freezing of walls in the cold season;
  • insufficient waterproofing of the room, as a result of which moisture begins to accumulate on the surfaces;
  • roof leakage.

Experts say that you can even provoke the appearance of mold by breeding ornamental houseplants. The most "favorite" habitat for her are the corners of the rooms, and she often accumulates on the surface of the facade walls and ceilings. At the moment, almost all building materials are susceptible to mold infection, which is extremely difficult to remove later.

Control methods

Even if you've recently done an expensive renovation, new mold stains can appear in a relatively short period of time. At first, they notice a strong unpleasant odor in the room, and mold spots appear only after a while. The structure of the fungus is soft and loose, it is easy to scrape it off or clean it off with a metal brush. However, this will only help get rid of the ugly stains, but will not solve the problem.

To achieve a successful result, it is recommended to carry out a whole range of works:

  • Fungus stains must be removed from surfaces.
  • The affected areas should be treated with an antifungal primer.
  • If possible, you need to get rid of the elements where it was not possible to remove the mold.
  • The room should be well ventilated and the humidity level inside the room should be adjusted.

Types of antiseptics

The primer is normal and antifungal. The first is aimed at preventing the appearance of mold, and the second is used to destroy fungal formations. In addition, antiseptics with antifungal additives have a longer lasting effect and penetrate deeply into the surface. The presence of fungicides in their composition prevents the appearance of new microorganisms. In addition to the fact that these funds remove the fungus, they are characterized by excellent antiseptic and antibacterial properties.

Antiseptics are:

  • water-soluble;
  • combined (in the form of a concentrate);
  • oil;
  • based on organic solvents.

There is also a difference in the composition of the primers. Let's consider the differences of each type separately.

You should be aware that such solutions are not suitable for application to plastered ceilings and drywall walls. It will take about 12 hours to dry completely.

Before purchasing this or that tool, you should read the instructions, because some of them are aimed only at preventing fungus and are not designed to completely eliminate bacteria. Also, when choosing, you should take into account the material on which it will be applied.

To achieve maximum results, you need to select a solution for a specific type of surface.

Application Tips

Regardless of which primer you choose, it should be applied directly to the affected areas. Knowing some of the nuances of using formulations against fungus, it will be easier to achieve a positive result.

  • It is necessary to apply a primer on a previously cleaned and dried wall. You can wash off the mold with the help of "Whiteness" diluted with water. Even if there are no stains left on the surface, this does not mean that you have gotten rid of them. For more effective removal, you can walk over the area with a building hairdryer or blowtorch.
  • It is necessary to properly ventilate the room. In the bathroom you can use a fan or convector. In other rooms, the windows are wide open, creating a draft.

  • Before applying an antifungal, surfaces cannot be treated with a conventional primer. They form a film, thereby blocking the penetration of antifungal agents into the walls. In this case, their use will be meaningless.
  • It is necessary to carry out the processing in dry rooms, preferably in the warm season.
  • Apply the primer with a brush, roller or spray. The most effective will be the use of a brush with natural bristles - this will allow you to apply the composition even in hard-to-reach places.
  • During the use of antifungal agents, safety measures must be observed. All work is carried out in protective clothing, a respirator and rubber gloves.
