Antifungal agent for walls: a comparative overview of the best options

Mold on the walls is not uncommon in modern homes and apartments. Spore formations multiply very quickly and if decisive measures are not taken to remove them, the fungus will migrate to the ceiling, floor, furniture and clothes.

For a quick solution to the problem, it is necessary to choose an effective antifungal agent for walls and eliminate the root cause of the appearance of mold microorganisms. We suggest you familiarize yourself with the most effective means of countering extremely dangerous biological effects.

We have described in detail how to use effective types of household chemicals, given options for the manufacture and use of folk formulations. The material is supplemented by visual illustrations and video guides.

Signs and causes of fungus formation

The appearance of the fungus on the walls is an extremely unpleasant phenomenon that can negate costly repairs in the apartment.

Mold not only spoils the appearance, it worsens the indoor climate and is harmful to human health. Timely identification of the "enemy" greatly facilitates the fight against fungus. Details on methods to combat a dangerous biological phenomenon are described in one of articles of our site.

Mold spores are toxic. Once in the human body, they can cause a number of diseases: allergies, bronchitis, migraines, tuberculosis and asthma. Elderly people and children are especially susceptible

The following signs indicate the appearance of a fungus in the house:

• the presence of gray, black, dark green dots and spots on the walls or ceiling;
• the appearance of a raw, unpleasant odor in the room;
• peeling paint, wallpaper, plastering, and darkening tile joints.

Some may note a deterioration in well-being - the concentration of attention decreases, headaches become more frequent, and fatigue arises.

It is necessary to remove mold in an integrated manner. The final and irrevocable disposal of the fungus can be achieved by eliminating the causes of its appearance.

The main reasons for the formation of the fungus: air humidity over 70% and temperature conditions from 20 ° C. “Weeping” windows - the first alarm

However, humidity and temperature indicators are far from the only factors in the development of harmful microorganisms.

Significant reasons include:

1. Lack or inadequate ventilation. As a rule, the fungus begins to develop in the corners of the room - in the place where stagnation of air forms. With sufficient “blowing”, turbulences are formed - air blows out spores, and excess moisture is discharged into the ventilation duct.
2. Poor waterproofing of the foundation. As a result of poor-quality construction, there is a capillary leakage of moisture from a moist foundation - the walls in the house become damp.
3. Poor water supply and sewage. Periodic wetting of the floor, ceiling, walls and engineering channels creates a favorable environment for the development of the fungus.
4. Thin freezing walls. Due to poor thermal insulation, a dew point shift occurs, condensate settles on the walls from the inside of the room.
5. Cold attic or leaking roof. This is a common cause of mold on the upper floors and attics.
6. Improper use of a humidifier. When creating tropical conditions for exotic plants, mold fungi sometimes settle in greenhouses.

Most decoration and building materials can be affected by fungus. Dark spots appear on the wallpaper, tile, wood trim and plaster.

In addition, mold is able to settle in household appliances, most often from its appearance washing machines, dishwashers and microwaves.

Varieties of fungicides

Most antifungal agents for walls contain fungicides - substances of biological or chemical origin that inhibit the development of fungi. Active components are added to various building compounds and mixtures to protect structural elements from mold.

Based on the destination, two groups of drugs are distinguished:

• primers for prevention;
• concentrated formulations for fighting.

Emulsions for prevention. The first group of antiseptics is used when performing repair work - before the walls are finished with a finish coating. Antifungal primers strengthen the base, increase adhesion, reduce the porosity of the material, remove mold and inhibit the further development of the fungus.

When choosing an antifungal primer, you need to pay attention to the composition. The emulsion should not contain carbendazim - a toxic fungicide banned in Europe

The determining factor in choosing a primer with an antiseptic against fungi and mold is the type of processing coating:

• reinforcing primer - suitable for putty and plastered walls for painting or wallpaper;
• deep penetration soil - optimal for low-porous substrates (drywall, brick and concrete), as well as for finishing with a “heavy” coating, for example, tiles;
• universal composition - processing of various types of surfaces.

Concentrates for mold removal. Means for treating surfaces affected by fungus. The compounds penetrate the structure of the material and destroy mold, lichens and mosses. Many concentrated preparations have a long-lasting effect and prevent re-infection.

Fungicidal emulsions of universal application and specialized ones for a specific base (wood, stone, concrete) are on the market. Narrower drugs are more effective

Emulsions for the prevention and removal of fungal formations are developed on the basis of different binders:

1. Latex - the composition does not contain salts of heavy metals, so the tool is recommended for the treatment of walls in living rooms. An additional plus is air permeability.
2. Acrylic - antiseptic drugs are applicable both indoors and outdoors.
3. Alkyd - emulsions are often used to treat wood substrates.

The form of release of primers and concentrates is a ready-to-use liquid. In order to prevent fungal formations, the concentrated emulsion can be diluted with water.

Primers for prevention

To prevent mold in wet rooms at the stage of repair and construction work, it is advisable to use primers with an antiseptic property.

# 1: Milkill - Brick and Concrete Processing

Among the disadvantages of the soil is the impossibility of its use on grounds that do not absorb moisture.

Application of 1-2 layers is recommended. On loose surfaces, you must adhere to the "wet" method - the next layer of the emulsion is applied to the previous dry one.

Antifungal Wood Products

Wood is the most susceptible to mold material. It should be treated with insecticides without fail. A tree damaged by a fungus collapses very quickly. Therefore, surface treatment must be carried out annually in a planned manner.

# 1: Dufa-Holzlasur - azure for wood

Dufa-Holzlasur - thin-layer, decorative glaze for restoration of old and protection of new wooden surfaces. Moisture-control and water-repellent coating protects the tree from the negative effects of precipitation.

An antifungal agent can also be used as a preventive measure against the appearance of mold - the emulsion is applied not only to the damaged area, but to the entire wall

Features of the action and use of the drug:

• after use, the risk of mold reappearance is reduced;
• before application, the concentrate is diluted with water in a ratio of 1: 2;
• the treated wall must be washed with water and dried in a day;
• with severe damage to the walls by the fungus, it is recommended to repeat the procedure after 36 hours.

Consumers note a lasting positive effect after cleansing the surface with an antifungal composition.

# 3: Dali - a universal antiseptic

Dali is a universal remedy that is highly effective against various bio-diseases. It is actively used as a preventative treatment of walls before staining with paintwork, as well as to remove the resulting fungus, blueness and mold.

Dali antifungal mortar is recommended for porous substrates: brick, plaster, concrete. The product does not contain chlorine and does not change the surface characteristics of materials

The tactics for disinfection and the consumption of concentrate depend on the purpose of the treatment:

1. Prevention The surface is cleaned of dirt and covered with a layer of antiseptic at the rate of 50-100 ml / sq.m.
2. Removal of biological lesions. Remove visible colonies of fungi and mold, wipe and dry the wall. To process with the Dali preparation, spending 50-250 ml / sq.m. After 6 hours, repeat the procedure.

During operation, safety precautions must be observed. Wear protective clothing, a respirator, goggles and gloves. The room should be well ventilated.

# 4: Fongifluid Alpa - “treatment” and prevention

Fongifluid Alpa is a fungicidal solution that destroys the source of biodegradation of the wall and prevents re-infection.

It is permissible to apply the fungicidal composition to wood, tile, brick, cement plaster, gypsum board and ceramic tiles. It can be used outdoors and indoors.

Fongifluid Alpa Features:

• the solution is ready for use;
• drug consumption - 1 liter per 4-5 square meters;
• drying of the surface after 6 hours, the possibility of painting the base - after 6 days.

The antifungal solution is highly effective against a large number of microorganisms. The product does not change color, gloss and texture of the surface.

Alternative methods against mold

If the extent of damage to the walls is insignificant, then it will be possible to prevent the further spread of the fungus using improvised means.

The video presents a test experiment on the effectiveness of various folk methods for removing mold from walls:

Method 1 Bleach. The composition of "whiteness" and similar preparations includes sodium hypochlorite. The component is detrimental to many types of fungi and mold spores. The disadvantages of the method:

• chlorine corrodes the surface and can ruin the walls;
• the active substance works superficially - a fungus remains inside the material;

It should be remembered that working with bleach is not safe for human health.

Method 2 Bleach paired with baking soda. In addition to these basic components, you will also need a liquid soap and a few drops of the essential oil pleasant for you personally. In general, it is not difficult to cope with the preparation and use:

Wishing directly wash the bath until white and put in order plumbing on our site will find a lot of very useful information.

Method 3 Vinegar. An acidic environment is detrimental to many bacteria. Table vinegar is non-toxic, but gives off a pungent odor. This drawback is easily eliminated by providing adequate ventilation.

Vinegar is sprayed onto a damaged surface or applied gently with a sponge. After one hour, the wall is washed and the room is ventilated

Method 4 Hydrogen peroxide. The solution has antiseptic, antifungal properties. Processing with a 3% composition is effective, but is fraught with the appearance of spots on the wall - peroxide bleaches the coating.

To apply the product, it is advisable to stock up with a spray gun:

Method 5 Baking soda. The simplest and safest method is to spray a wall with a solution of soda (1 teaspoon of sodium carbonate per liter of water). After 1 hour, wipe the surface with a dry cloth. It is not necessary to remove the remains of the solution - soda will prevent the re-formation of the fungus.

Method 6 Borax (it is sodium tetraborate). The use of natural cleaning products is a priority in terms of maintaining a clean environment.

Buru without problems and prescriptions can be purchased at any pharmacy at a very affordable price.

Method 7 Ammonia. In this case, no additional funds and preparations will be required, although the cost of ammonia can not be called the most budget.

Ammonia is strictly forbidden to mix with bleach, so as not to be poisoned by the extremely toxic gas generated by the combination of these chemicals.It is also unacceptable to add to household cleaning products made on the basis of chlorine or ammonia, for example, to liquids for washing windows.

Conclusions and useful video on the topic

The video will introduce the causes of the appearance of mold, the prerequisites for its appearance, as well as the methods of controlling and preventing this negative phenomenon:

To achieve a positive result in the fight against mold, it is necessary to eliminate the root cause of its formation and choose the optimal antiseptic. To avoid the re-development of microorganisms, it is important to restore the circulation of air in the room and to ensure the dryness of the walls.
