Mold on walls is a common occurrence in homes and apartments. The reproduction of spore formations occurs quickly, and if they are not eliminated, the fungus can move to other surfaces. To eradicate the problem will allow an antifungal agent for the walls. Popular drugs are described in the article.
Signs
The occurrence of a fungus is an unpleasant phenomenon that can damage expensive repairs. Mold can not only spoil the appearance, but also worsen the microclimate of the room, and harm people's he alth. With the timely identification of the “enemy”, it will be possible to simplify the fight.
Mold spores are toxic. Once ingested, they lead to:
- allergies;
- bronchitis;
- migraines;
- tuberculosis;
- asthma.
The elderly and children are especially susceptible. The appearance of the fungus is indicated by gray, black, dark green dots and spots on the walls and ceiling. A damp, unpleasant odor is also formed, exfoliatespaint, wallpaper, plaster crumbles and tile joints darken.
Some report a deterioration in well-being - decreased attention, increased headaches, fatigue. It is necessary to eliminate mold in a complex way.
Reasons
The main reasons for the formation of the fungus is considered to be air humidity over 70% and temperature from 20 degrees. Weeping windows are a warning sign. But these are not the only factors in the appearance of harmful microorganisms. Fungus spawns at:
- Lack or insufficient ventilation. Usually the fungus develops in the corners of the premises - in areas where air stagnation occurs. If the “blowing” is sufficient, turbulence appears. As a result, spores are blown out with air, and excess moisture is eliminated into the ventilation duct.
- Poor-quality foundation waterproofing. Because of this, there will be capillary suction of moisture from the foundation - the walls in the room will become damp.
- Poor condition of the plumbing and sewer leaks. With periodic wetting of the walls, a positive environment is provided for the development of the fungus.
- Thin freezing walls. Due to insufficient thermal insulation, there is a shift in the dew point, and condensate accumulates on the walls inside the room.
- Cold attic or leaky roof. This is a common cause of mold on upper floors.
- Misuse of humidifiers. With the creation of favorable conditions for exotic plants, mold fungus sometimes appears.
Many finishing and building materials are affectedfungus. Dark spots appear on wallpaper, tiles, wood trim and plaster.
Types of fungicides
Usually fungicides against mold. These are biological or chemical substances that inhibit the development of fungi. Active ingredients are in the composition of building mixtures to protect against mold. Depending on the purpose, there are 2 types of funds:
- primers that perform the function of prevention;
- concentrated blends.
Emulsions for prevention are used during repairs - for finishing walls with a final coating. Antifungal primers can strengthen the substrate, increase adhesion, reduce the porosity of the material, get rid of mold and protect against the development of fungus.
When buying a primer, you should pay attention to the composition. The emulsion should not contain carbendazim, a toxic fungicide that is banned in Europe. An important factor when choosing is the type of treatment cover:
- strengthening primer is chosen for puttied and plastered walls for painting or wallpaper;
- Deep penetrating primer is the best choice for low porous substrates;
- different types of surfaces are treated with a universal composition.
There are other antifungal agents for walls - concentrates. They treat areas that are affected by the fungus. Means penetrate into the structure of the material and get rid of mold, lichen, moss. Many concentrated preparations have a long-term effect and do not allow secondary infection. For prevention and eliminationfungi use formulations based on the following components:
- latex - the composition is enriched with s alts of heavy metals, so the walls in living rooms are treated with the product;
- acrylic - antiseptics are used indoors and outdoors;
- alkyd - emulsions are often used to treat wooden surfaces.
Primers and concentrates are immediately ready for use. For prevention, the concentrated emulsion is diluted with water.
Milkill
This is an effective anti-fungal wall cleaner. In the latex emulsion, the active ingredient is a biocide that destroys fungal and mold spores. The tool is used as a prophylaxis for finely porous and low-absorbent surfaces before finishing. The emulsion is ideal for foundations, swimming pools, brick and concrete walls, drywall and plywood.
250 g/sq. m. It is desirable to process in 2-3 layers. The penetration depth of the agent is 1-5 mm. The emulsion dries up in a day. It is chosen for processing inside and outside the house. The mixture is not homogeneous, so it must be mixed before use. Works are carried out at a temperature of 5-30 degrees.
Acryl Grundierung
This is a deep penetration wall antifungal agent with antibacterial action. Acrylic primer is perfect for concrete, brick walls, facade or interior painting. The binder is an acrylic copolymer, the main color is translucent white with purpletone.
This product is environmentally friendly and odorless. The composition dries out in a day. On top of the primer, you can apply different water-based paints. The use of a compound reduces paint consumption by reducing the absorbency of the surface.
Schimmelstopp Dufa
This additive is fungicidal. It is used with synthetic plasters and facade, water-borne emulsion paints. The concentrate has a long-term protective effect against the appearance of mold, fungus and algae. The product is chosen for covering walls inside and out.
One container is enough for 25 kg of plaster or 10 liters of paint. The tool should not be used at temperatures below +5 degrees, in the rain or on very hot surfaces. After adding the primer to the paint or plaster, the mixture is stirred. The anti-mold agent is applied to a clean and dry substrate.
Mixonit GR43
Universal primer is added to dry building mixes. The agent is applied to mineral coatings with a high absorption capacity. They process concrete, brick, gypsum, cement, glass-magnesite sheets, drywall, foam block and expanded clay block.
The emulsion has no unpleasant odor. It also has vapor permeability - a "breathing" protective layer appears. The product penetrates up to 10 cm. The main function is to protect against the formation of mold, fungi, bacteria.
Ceresit
Antifungal solution Ceresit CT 99 is one of the most popular for eliminating mold, fungi, lichen. The product is environmentally friendly, can be used indoors and outdoors. Mineral surfaces are treated with a concentrate: brick, concrete, plaster. Not suitable for metal substrates.
Ceresit CT 99 contains organic biocides. Contains no heavy metals. There are no marks after the procedure. The drug is vapor permeable. It takes 4-5 hours to completely dry. Before use, the drug is diluted with water in an amount of 1:2 to 1:5 - it all depends on the level of damage to the wall. Apply the solution with a brush.
Fungiflud Alpa
Fongifluid Alpa is a fungicidal solution that destroys wall biodegradation and protects against secondary infection. The duration of action is about 2 years. After applying the solution, the coating "breathes", so there will be no deterioration in the microclimate in the room.
This compound is designed for wood, tile, brick, cement plaster, drywall and ceramic tiles. The surface dries in 6 hours. The solution is effective against a variety of microorganisms. The drug does not change the color, gloss and texture of the surface.
Olympus
"Olympus Stop Mold" - a product designed for baths, basements, cellars, greenhouses and apartments. It does not contain chlorine compounds and volatile toxic components. The composition is colorless and safe for humans and animals.
Olymp Stop Mold is ideal for treating concrete, brick, painted and plastered surfaces. More of ituse if the walls are wooden, ceramic, stone, plasterboard.
Nortex
"Nortex-disinfector" - a product that disinfects concrete from the formation of biodegraders. The composition allows you to get rid of mold, protect against its reappearance. It also has an antiseptic function. "Nortex-disinfector" increases the service life of concrete walls.
The product has a long-term protective effect. It is able to contact with many paints and varnishes. After processing, a strong washout protection is created. The disinfectant is applied to stone, concrete, brick.
Processing rules
How to remove mold from walls? The procedure is as follows:
- First you need to remove the coating.
- Then the depth of the damage to the surface is determined.
- Then wet the wall with water. This keeps the spores out of the air.
- Using a spatula, it is necessary to remove part of the plaster with fungus and mold.
- Affected areas are cleaned with sandpaper.
- It is necessary to thoroughly dry the surface. You can use a fan heater.
- You can apply antifungal agent in 1 layer.
- After about 5 hours, processing is repeated.
- Requires 4-5 coats for maximum effect.
- The walls are covered with an antiseptic primer.
- Plastering is carried out with a solution in which an antiseptic is present.
- If the wall is again pasted over with wallpaper, then an antiseptic is added to the glue.
Thisthe whole procedure, how to remove mold from the walls. High-quality processing will serve as protection against the reappearance of fungi. It remains only to maintain a favorable microclimate in the room.
