Mold on walls is a common occurrence in homes and apartments. Reproduction of spore formations occurs quickly, and if they are not eliminated, the fungus can pass to other surfaces. An anti-fungal agent for walls will eradicate the problem. 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 the health of people. With the timely identification of the "enemy" will simplify the fight.
Mold spores are toxic. After penetration into the body, they lead to:
- allergies
- bronchitis;
- migraine;
- tuberculosis
- asthma
Especially susceptible are the elderly and children. The appearance of the fungus is indicated by gray, black, dark green dots and spots on the walls and ceiling. A raw, unpleasant odor is still formed, paint, wallpaper peels off, the plaster crumbles and the tile joints darken.
Some note a deterioration in well-being - a decrease in attention, an increase in headaches, and rapid fatigue. Mold must be removed comprehensively.
Causes
The main reasons for the formation of the fungus is considered to be humidity above 70% and a temperature of 20 degrees. “Weeping” windows are an alarming sign. But these are not the only factors causing the appearance of harmful microorganisms. The fungus appears when:
- Lack or inadequate ventilation. Usually, the fungus develops in the corners of the premises - in areas where air stagnation occurs. If "blowing" is sufficient, turbulences appear. As a result, spores are blown out with air, and excess moisture will be eliminated into the ventilation duct.
- Poor waterproofing foundation. Because of this, there will be a capillary leakage of moisture from the foundation - the walls in the room become damp.
- Unsatisfactory condition of the water supply system and leaking sewage system. With periodic wetting of the walls, a positive environment for the development of the fungus is provided.
- Thin freezing walls. Due to insufficient thermal insulation, a dew point shift is observed, and condensation accumulates on the walls indoors.
- Cold attic or leaking roof. This is a common cause of mold on the upper floors.
- Improper use of humidifiers. With the creation of favorable conditions for exotic plants, mold sometimes occurs.
Many finishing and building materials are affected by the fungus. Dark spots occur on wallpaper, tile, wood finishes and stucco.
Types of fungicides
Usually anti-mold agents are fungicidal. 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 mixtures.
Emulsions for prevention are used in the implementation of repairs - for wall finishing with a finishing coating. Antifungal primers can strengthen the base, 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 prohibited in Europe. An important factor when choosing is the type of processing coating:
- reinforcing primer is chosen for putty and plastered walls for painting or wallpaper;
- deep penetration primer is the best choice for low porous substrates;
- universal composition process different types of surfaces.
There are other antifungal agents for walls - concentrates. They treat areas that are affected by the fungus. Means penetrate the structure of the material and relieve mold, lichens, mosses. Many concentrated preparations have a long-lasting effect and do not allow secondary infection. For the prevention and elimination of fungi, formulations are used based on the following components:
- latex - the composition is enriched with salts of heavy metals, therefore, the tool processes the walls in living rooms;
- acrylic - antiseptic agents 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
It is an effective antifungal agent for walls. In the latex emulsion, the active ingredient is a biocide, which destroys the spores of fungi and mold. The tool is used as a prophylaxis for finely porous and low-absorbing surfaces before finishing. The emulsion is ideal for foundations, pools, brick and concrete walls, plasterboard and plywood coatings.
250 g / sq is consumed per layer. m. It is advisable to process in 2-3 layers. The penetration depth of the product is 1-5 mm. The emulsion dries per day. She is chosen for processing inside and outside the house. The mixture is heterogeneous, so mix before use. Work is carried out at a temperature of 5-30 degrees.
Acryl grundierung
This is an antifungal agent for deep penetration walls, which has an antibacterial effect. Acrylic primer is perfect for concrete, brick walls, facade or interior painting. The binder component is an acrylic copolymer, the main color is translucent white with a purple tone.
This product is environmentally friendly, odorless. The composition dries in a day. Various water-based paints can be applied on top of the primer. The use of the composition reduces paint consumption, reducing the absorbing effect of the surface.
Schimmelstopp dufa
This additive is fungicidal. It is used with synthetic plasters and facade, waterborne dispersion paints. The concentrate has a long protective effect against the appearance of mold, fungus and algae. The tool is chosen to cover the walls inside and out.
One container is enough for 25 kg of plaster or 10 l of paint. The product should not be used at temperatures less than +5 degrees, in the rain or on very hot surfaces. After adding a primer to the paint or plaster, the mixture is mixed. The anti-mildew is applied on a clean and dry base.
Mixonit GR43
Universal soil is added to dry mortar. 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 - there is a "breathing" protective layer. The product penetrates up to 10 cm. The main function is protection against the formation of mold, fungi, bacteria.
Ceresit
The antifungal solution Ceresit CT 99 is one of the most popular for eliminating mold, fungi, lichens. The product is environmentally friendly, can be used indoors and outdoors. Concentrate treats mineral surfaces: brick, concrete, plaster. On metal substrates not applicable.
Ceresit CT 99 includes organic biocides. The composition does not contain heavy metals. There are no traces after the procedure. The drug is vapor permeable. It takes 4-5 hours to fully 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 the biodegradation of the wall and protects against secondary infection. Duration of action is about 2 years. After applying the solution, the coating “breathes”, so there will be no deterioration of the microclimate in the room.
This composition is intended for the processing of wood, tiles, bricks, cement plaster, drywall and ceramic tiles. The surface dries in 6 hours. The solution is effective against many microorganisms. The drug does not change the color, luster and texture of the surface.
"Olympus"
“Olympus Stop Mold” is a product intended for bathtubs, basements, cellars, hotbeds and apartments. It lacks chlorine compounds and volatile toxic components. The composition is colorless and safe for people and animals.
The preparation Olympus Stop Mold is ideal for treating concrete, brick, painted and plastered surfaces. It is also used if the walls are wooden, ceramic, stone, plasterboard.
Nortex
"Nortex-disinfector" - a means of disinfecting concrete from the formation of biodegradants. The composition allows you to get rid of mold, protect against its reappearance. It also has the function of an antiseptic. Nortex-disinfector extends the life of concrete walls.
The product has a long protective effect. It is able to contact with many paints and varnishes. After processing, a strong protection against leaching is created. The disinfector is applied to stone, concrete, brick.
Processing Rules
How to remove mold from the walls? The procedure is as follows:
- First you need to remove the coating.
- Then the depth of the surface lesion is determined.
- Then they wet the wall with water. This protects against spores from entering the air.
- Using a spatula, it is necessary to remove part of the plaster with fungus and mold.
- Affected areas are cleaned with sandpaper.
- Dry the surface thoroughly. You can use a fan heater.
- You can apply an antifungal agent in 1 layer.
- After about 5 hours, processing is performed a second time.
- To ensure maximum action you need 4-5 layers.
- The walls are coated with an antiseptic primer.
- Plastering is carried out with a solution in which an antiseptic agent is present .
- If the wall is again glued with wallpaper, then an antiseptic is added to the glue.
This is the whole procedure of how to remove mold from the walls. Quality treatment will protect against the reappearance of fungi. It remains only to maintain a favorable microclimate in the room.
