Today, quite a lot of people have encountered such a problem as plaque on the walls. This is quite an unpleasant and dangerous phenomenon. Thanks to their special composition, antifungal primers cope well with mold. The danger of this problem lies in the speed of its spread. Therefore, the fungus should be destroyed promptly. Otherwise, it may have a negative effect. In this review, we will consider what a primer from fungus and mold is, and how to use it to achieve the optimal result.
Why get rid of this trouble?
Spores of the fungus can adversely affect the health status of people living in the room. They are volatile and easily penetrate the respiratory tract, causing severe allergic reactions. Another reason why these microorganisms are especially dangerous is that fungi emit harmful toxins during their life. With their excessive accumulation, a person can develop diseases such as asthma, rhinitis, bronchitis, otitis media, mycotoxicosis and many others. Often a fungal infection leads to damage to internal organs and disturbances in the work of the cardiovascular system.
Mold is terrible not only for health. It also negatively affects the condition of surfaces. After prolonged exposure, plaster can become loose and easily move away from the walls. Wooden elements under the action of a fungus are simply destroyed.
Causes of occurrence
Let's dwell on this in more detail. Mold can appear in any room. At the initial stage, it is rather difficult to recognize it. Spores can imperceptibly multiply inside the material.
The main reasons for the appearance of the fungus include:
- insufficient protection of the base of the structure from moisture;
- poor protection of the foundation and walls of the building from the cold;
- poor quality of processing joints between panels;
- emergency condition of the roof;
- freezing of the attic;
- poorly installed window units;
- improper functioning of the ventilation system;
- irregular ventilation of the room;
- the inability of the floors to resist moisture penetration.
Such factors also cause the development of mold. To prevent its occurrence, a mold and fungus primer is used. This composition is used both at the stage of rough finishing, and at the final stage of repair work.
Types of primers
So what are they like? What can be a fungus and mold primer? Since plaque can affect surfaces of various types, there are several varieties of antifungal compounds. They are used for processing floors and walls of brick, wood and concrete. Apply a special liquid usually on plaster or drywall.
Antiseptic primer against fungi and molds can be of the following types:
- Normal: used to prevent mold.
- Deep penetration: used to treat surfaces already affected by the fungus. Such impregnation helps to destroy spores that have already entered the material. The composition is characterized by prolonged exposure.
Types of primers by composition
To date, there are many. The composition of the antiseptic primer against fungi and molds is divided into the following types:
- Acrylic A fairly common group of compositions containing acrylic resins that increase the strength characteristics of materials. The acrylic primer does not contain harmful components. In addition, it dries out pretty quickly. Such a primer from mold and mildew is used to treat rooms with high humidity - pools, basements, bathrooms and kitchens. The composition of this type is also suitable for processing walls of buildings.
- Mineral Typically, such a primer is used against mold and mildew on concrete and brick surfaces. A layer of silicate materials or plaster can be applied on top of it. This primer may contain concrete or gypsum. It contains only natural components that do not have a negative effect on the human body.
- Alkyd. Suitable for wood surfaces. This composition prevents the spread of plaque, and also prevents the swelling of wood. Such a primer against fungus can be used to protect steel, tile and glass surfaces. It can also be used for processing plaster and drywall, however, in this case the effect will not be so pronounced.
- Quartz. Soil from mold and fungus based on quartz is suitable for application under decorative plaster and paint. It contains sand, which contributes to a high level of adhesion to the surface.

Anti-plaque and rot detergents for treating wooden surfaces
What is their feature? It is believed that wood is highly susceptible to mold and mildew. For this reason, it must be well treated with insecticides. This procedure is recommended annually.
The best means to protect wooden surfaces are:

- Altax Boramon C30 - excellent impregnation, helps protect wooden surfaces from small insects and pathogenic microorganisms.
- Pinotex Base - used for outdoor processing. Typically, this composition covers the facades of buildings, fences, doors, windows.
Emulsions
Means of this type help to easily and quickly eliminate the foci of the spread of fungal infection.
The following compounds are most widely used today:
- Ceresit CT 99: Duration of exposure. This composition is environmentally friendly and suitable for processing both inside and outside buildings. It can be applied to concrete and brick.

Folk remedies
At-hand tools can be effective in combating mold in the event that the fungus has not yet spread to the entire surface.
Best for eliminating fungus are:
- hydrogen peroxide;
- baking soda;
- vinegar;
- bleach.
Of course, home remedies are not as effective as industrial preparations, but they are much cheaper.
How to prepare the surface for applying the product?
The fungus and mold primer will show a good result after application only if the treated area has been properly prepared. If mold has already spread on the walls, it should be removed. Best for this purpose are bleach or whiteness. They must be applied to the affected surface with a stiff brush. The primer is applied only after the disinfectant has dried. The material can be additionally heated with a hairdryer. Thermal exposure will help the antifungal compound penetrate deeper into the treated surface and enhance its effect.
How to apply a primer?
So what is needed for this? To apply the composition to the walls, you can use a roller, brushes or a special spray. The first tool is only suitable if the work surface has a small area. Hard to reach places are most easily handled with a brush. First, the primer simply needs to be spread over the surface. You should wait until the first coat has dried, and then apply the second. All procedures are carried out only at positive temperatures.
Selecting the composition is based on the type of surface being treated. For example, a primer for mold and mildew on concrete will differ from a product for wooden surfaces.
It is important to observe safety precautions when working with plaque. Mold is extremely dangerous to health. Therefore, when processing surfaces, be sure to use personal protective equipment, such as glasses, gloves, a hat, a respirator and protective clothing. Try to prevent the penetration of the antifungal composition on exposed skin. If the product nevertheless gets on the skin, wash it thoroughly under running water.
Preventative measures
In order to avoid future problems associated with the appearance of black mold spots on the walls, try to take care of the absence of sources of moisture even at the stage of designing the structure. Waterproofing should be organized in accordance with all standards. Structures and buildings that are not equipped with drainage trenches along the external perimeter that serve to drain groundwater and precipitation are at risk.
Conclusion
To protect the surfaces of your home from fungus and mold, you must use special antiseptic and antifungal primers. In order to avoid the appearance of fungal colonies, treatment with such formulations should be carried out regularly.
