How to choose an anti-mold and mildew primer?

Fungal spores tend to appear in poorly ventilated rooms, however, a favorable environment must form for their reproduction. To avoid such a nuisance, an antifungal primer can be used. It is used against mold that can ruin your new renovation.

Black spots on the ceiling and walls are found in rooms with high humidity. This is nothing more than parasitic fungi. Neighborhood with them is fraught with unpleasant consequences. The unaesthetic appearance of the room is the smallest of them. Fungal spores can harm human health, especially the sensitive child's body. The respiratory organs serve as a conduit for spores into the body. The fungus is capable of provoking a number of diseases, including severe ones.

Mycotoxins are harmful substances secreted by fungi. It is they who are harmful to health, can cause a decrease in immunity, chronic fatigue, and cause poisoning. Allergic reactions, bronchial asthma, diathesis in children, migraines, runny nose, bronchitis and even oncology - this is an incomplete list of diseases that can provoke black spots in a living room.

Mold formation actively occurs subject to the presence of constant dampness. High moisture is a sign that should alert you.

The following reasons for the emergence of fungal colonies are distinguished:

• The foundation of the building has flaws in waterproofing, moisture from the soil penetrates into the wall.
• Violations of the waterproofing of the facade leads to freezing of the walls.
• Increase of moisture inside the building during insulation due to non-compliance with vapor permeability conditions.

• The use of "non-breathing" materials in wall decoration, no air circulation.
• Leaking pipes.
• The installation of plastic windows leads to the appearance of dew.
• Violation of ventilation.

The defeat of the walls by the fungus leads to the acceleration of their destruction. Getting rid of the existing fungus, as well as preventing its appearance, is a primary task, for the solution of which there is an arsenal of means.

The antifungal primer has a special composition developed by specialists in order to neutralize fungal spores and prevent their return.

It is necessary to treat surfaces with an antifungal composition in a bath, pool, bathroom, etc.

The use of a primer containing fungicides destroys mold by penetrating the thickness of the wall, filling the pores of the plaster layer. The antifungal ingredients included in a mold pore primer are called fungicides.

The material for applying the primer determines its composition. The type of top finishing is also taken into account.

A specialized primer with fungicides in the composition can have different types of bases:

• acrylic;
• alkyd;
• oil;
• mineral.

Antiseptics are used as preventive measures during repair or construction work. In the fight against existing fungal infections of the walls, soil solutions with a higher concentration of antiseptic substances and penetrating ability are used.

Warm rooms with high humidity and porous coatings greatly increase the risk of mold foci. The most influential factor is moisture: it is a breeding ground for fungal spores.

Primers for construction purposes are produced with the inclusion of special substancesthat contribute to the formation of a film on the applied surface. Varieties of adhesive, resinous, oil mixtures, substances that contribute to the rapid drying of the surface, antiseptic additives are able to give the primer properties intended for solving various problems.

Manufacturers create solutions that have different purposes according to the type of surface to be treated: for concrete, wood, brick, drywall.

Different surfaces require different types of primer. To effectively solve the problem of getting rid of mold, you need to remember that anti-mold is intended for concrete surfaces. The use of such a primer for wooden surfaces is not effective and is not recommended.

There are several types of fungicidal compositions for their effect on the surface:

• capable of deep penetration - strengthen porous surfaces, penetrate into them by five centimeters;
• penetrating - strengthen the concrete composition and the layer of plaster to a depth of five millimeters;
• adhesive - cover the surface with a dense film with adhesive properties;
• special purpose - endowed with special characteristics such as anti-corrosion, frost-resistant, etc.

Primers are also varied for their purpose. There are compositions for surfaces of metal, mineral, painted or with plaster, with laid ceramic tiles.

In order to prevent the formation of mold and get rid of it, an integrated approach is needed.

This is the only way to ensure the complete elimination of fungal spores and completely destroy the lesion focus:

• Elimination of the causes of the formation of excess moisture in the room. It is imperative to find the source of the mold and fix any irregularities in the joints of walls, slabs or pipes. If you do not do this efficiently, the fungus will return and you will have to start the whole range of activities anew.
• Adjustment of the effective functioning of the ventilation system. It is necessary to ensure the correct installation of window slopes, take care of regular ventilation of the room.

• With a solution of water and detergent (for example, bleach) with a rag, wash off black fungal stains from the surface of the walls or ceiling, after which the rag must be thrown away, or better
• burn. Such a procedure is necessary so that fungal spores do not spread throughout the room during further stages of work.
• Dry well the washed surface using heating devices or strong drafts.
• Completely remove the infected plaster area.

• Use a blowtorch or a gas burner to treat the area of ​​the surface freed from plaster to dry and disinfect it.
• Clean the treated surface from carbon deposits and dust.
• Apply a special anti-fungal primer to the surface.
• After four hours, the surface can be re-finished (plastering, wallpapering, paint or tiles).

A paint brush is used to apply the primer solution to small areas., on areas of more harmful size - a roller, on large surfaces - a spray bottle. The primer layer must be even, without gaps. For the best effect, the primer is applied more than once at the rate of ½ liter of composition per 1 square meter. Apply layers of primer or antibacterial paint correctly perpendicular to one another to avoid bald spots.Rubbing movements when applying antifungal agents will provide a deeper penetration of the composition into the treated surface.

In addition to working inside the building, it is necessary to inspect its outer side. Fighting from the outside and from the inside at the same time will be more productive.

An important rule is compliance with safety measures when working with a fungus. Mold is dangerous to health, therefore, when working to get rid of it, you must use personal protective equipment: rubber gloves, tight glasses, a respirator, a hat, thick clothing.

Another immutable rule when detecting a fungus and wanting to get rid of it is not to use a primer that does not have antifungal properties. Such a primer creates a film on the affected surface, under which the mold feels at ease and multiplies even more actively, penetrating deeper.

In order not to have a complex of problems associated with the formation of black spots in the future, it is advisable to ensure that there are no sources of constant moisture at the construction stage. This will require the organization of waterproofing in accordance with all the rules.

A house that is not equipped on the outside with drainage trenches to drain precipitation and groundwater is at risk. A foundation treated with a leveling base with an antifungal composition on the upper end or as a whole is the key to good waterproofing.

At its cost, the primer from mold and mildew differs from simple compositions in a larger direction. However, the use of such a primer is much less expensive compared to measures to get rid of the resulting mold spots. Therefore, it is impractical to save on a primer against mold.

In addition to antiseptic and antifungal properties, primers have a protective effect on walls. Rodents, larvae and other parasites will not destroy surfaces covered with special compounds. Such processing is relevant for wooden surfaces, since this material is susceptible to rapid destruction in adverse conditions.

The following manufacturers of "fungus killers" are always popular among construction and repair specialists:

• Mill kill. The composition is capable of penetrating walls to a depth of three centimeters. Helps to strengthen the porous and fragile surface. Recommended for damp rooms. Effective with two and three times the number of layers.
• Elegant 296. The composition has insulating properties, which prevents the substrate from getting wet. Designed for all surfaces. Possesses good black hiding properties. Forms a film on the surface that prevents wetting.
• "Areal-Example". Acrylic based primer containing various types of fungicides. Eliminates harmful bacteria, protects against their reactivation. It strengthens the treated surface well and is comfortable to work with due to the absence of a pungent odor.

• Acryl Grundierung. Acrylic based composition. Reduces the ability to absorb moisture at the application site.
• Ceresit CT-99. The composition is highly concentrated, while safe from an environmental point of view. Penetrates deep into the surface, retains its properties for a long time, is applicable on internal and external surfaces.

An important factor in choosing an antifungal primer is that to prevent the formation of mold and mildew, a primer must be selected that is suitable for the application conditions. To combat an existing fungal colony, a concentrate with a high fungicide content is required.
