Fungus and mold primer

Living in infected rooms often causes a weakening of the general condition of the body. The spores of the fungus are volatile, easily penetrate by air into the respiratory organs of a person, causing allergic reactions. In addition, microorganisms release toxins throughout their life.

Their excessive accumulation in the room can provoke the development of such diseases:

Important! In the most severe cases, a fungal infection can lead to disturbances in the cardiovascular system and damage to internal organs.

In addition to causing harm to health, mold negatively affects the condition of the premises and can cause the destruction of surfaces. With its long exposure, the plaster becomes loose and easily peels off, and the wooden elements turn into dust.

Reasons for the appearance

Mold can appear in any premises, and it is not easy to recognize it. It is especially difficult to do this in the early stages of occurrence, since spores breed inside the material.

The main causes of the appearance of the fungus:

  1. Inadequate protection of the foundations of buildings from moisture.
  2. Weak protection of the walls and foundation of the object from the cold.
  3. Poor processing of joints between panels.
  4. The emergency condition of the roof.
  5. Freezing the attic.
  6. Poor installation of window blocks.
  7. Poor ventilation system.
  8. Irregular ventilation of the room.
  9. Inability of floors (mainly wood) to withstand penetration of moisture.

In all these cases, mold receives suitable conditions for development. To prevent the antifungal composition, it is necessary to use not only at the stages of rough finishing, but also at the final stage (when applying plaster and putty).

Types of primers as intended

Since mold is capable of hitting surfaces of various materials, it is necessary to process floors and walls of concrete, wood, and brick. The primer is applied to drywall or plaster. Compositions are produced for each type of material.

Based on the purpose, antifungal primers are of the following types:

  1. Plain. Used to prevent mold.
  2. Antifungal primer deep penetration. It is used to treat surfaces affected by the fungus. Such impregnation destroys the spores inside the material and is characterized by a long action.

Types of primers by composition

The composition of the anti-mold and fungal agents includes various components, in particular acrylic and antiseptic, water and minerals. Depending on this, these types are distinguished:

  1. Acrylic A fairly common group, including acrylic resins, which improve the adhesion properties of materials. Acrylic primer does not contain harmful substances and dries quickly enough. It is used for processing rooms with high humidity: bathrooms, kitchens, cellars and pools. This primer is applied to the exterior walls of buildings.
  2. Mineral It is used for processing concrete and brick surfaces, applied to a layer of plaster and silicate materials. The composition contains gypsum or cement. It contains natural substances, therefore it does not have a negative effect on the human body.
  3. Alkyd. This primer is suitable for the treatment of wooden surfaces. The composition not only prevents the spread of the fungus, but also prevents the swelling of wood. The use of this primer for the protection of tiled, steel or glass surfaces is allowed. It is possible to use drywall or plaster for processing, but in this case the effect will not be so pronounced.
  4. Quartz. It is applied under paint and decorative plaster. The composition contains sand, which contributes to a sufficiently high level of adhesion of surfaces (adhesion). The final layer is rough.

Primers for prevention

Such products are designed to prevent the growth of harmful bacteria. The most common are:

  1. Milkill - processing of bricks and concrete. The composition of the primer makes it easy to penetrate deep into the treated surface. It is allowed to cover materials affected by microorganisms.
  2. Acryl Grundierung is an acrylic-based deep penetration composition characterized by antibacterial, antifungal and adhesive properties. Suitable for treating concrete or brick walls before applying putty and paint.
  3. Schimmelstop Dufa is a fungicide supplement. It is used as an additional tool for paints and plasters. It is applied with them to places where mold appeared. Used to prevent the development of fungus.
  4. Mixonit GR43 - has a wide range, is added to dry building mixes. A deep penetration agent, applied to mineral coatings, characterized by high absorption capacity.

Antifungal Wood Products

Wood is considered the most susceptible to mold. For this reason, it must be treated with insecticides, and more than once. It is recommended to do this every year.

Basic means for protecting wooden surfaces:

  1. Dufa-Holzlasur - azure for wood. Thin-layer decorative composition for restoring old and saving new materials. It protects wood from the negative effects of precipitation, destroys existing mold spores and prevents the appearance of regular formations.
  2. Altax Boramon C30 - indelible impregnation. Protects material from mold and small insects, eliminates developing microorganisms.
  3. Pinotex Base - exterior wall treatment. An alkyd-based compound is applied to fences, facades, windows and doors immediately before painting.

Mold control emulsions

These special tools can eliminate fungal foci. The most popular are the following:

  1. Ceresit CT 99 - differs in long action. Environmentally friendly concentrate, suitable for processing both internal and external mineral surfaces (concrete, brick, plaster).
  2. ABEDIS 06 - used to remove organic plaque. The drug is applied to brick walls, tiled surfaces, plaster, concrete walkways. Used for prevention.
  3. Dali is a universal antiseptic. It is used for prevention before painting, to remove existing mold. It is applied to concrete, brick, and plaster substrates.
  4. Fongifluid Alpa - “treatment” and prevention. Destroys existing lesions and prevents re-infection. The product processes wooden and brick surfaces, drywall and ceramic tiles, tiles and cement plaster. The concentrate does not prevent air from penetrating the materials, which positively affects the indoor microclimate.

Alternative methods against mold

The use of improvised means is justified when the mold has not yet spread to the entire surface. Mostly used:

  • bleach,
  • hydrogen peroxide,
  • baking soda
  • vinegar.

Home remedies are not as effective as industrial preparations, but much cheaper.

What is mold dangerous?

Mold fungus is a living organism that produces substances that are harmful to human health. If a favorable environment is created, then mold spores begin to spread rapidly and destroy surfaces.

Living in a room with mold negatively affects immunity and labor productivity. Spores of the fungus are allergens that can penetrate by air into the respiratory organs of a person. As a result, unpleasant allergic reactions occur.

It is quite difficult to get rid of mold. Even if you clean the surface of it, this will not improve the situation. Its spores penetrate into the depths of the material and after a certain time germinate again. Therefore, an antifungal composition is required that penetrates deep into the material.

It is much easier to prevent the spread of mold during the construction or repair phase. For this, the surface is treated with protective compounds.

Preventive measures

Antifungal primer for walls is the main means to prevent the spread of mold. Additionally, conditions conducive to its occurrence must be excluded. Additional preventive measures will help protect the room from the fungus:

  • Monitor the condition of water supply systems in order to timely eliminate the increase in humidity.
  • During construction, comply with the requirements for hydro and thermal insulation.
  • Thoroughly seal butt joints between parts of load-bearing structures.
  • Equip high-quality ventilation, especially in kitchens, bathrooms, porches and other similar rooms.
  • If bulky pieces of furniture are close to the walls, you need to change the layout.
  • Ventilate the room periodically.
  • Equip the heating in the house.
  • Timely repair the water supply system.
  • Use anti-mold and mildew products.

Mildew begins to spread actively in the heat, if there is increased humidity. If such conditions are created in the room, then measures must be taken to eliminate them.

Primer Benefits

The antibacterial primer contains fungicides - special substances that can destroy harmful microorganisms. Additionally, the primer performs the following tasks:

  • reduces the consumption of subsequent finishing materials (paint, plaster, wallpaper, etc.),
  • the quality of the finish is improved,
  • eliminates the occurrence of cracks after staining,
  • increases the strength of the finish,
  • neutralizes unpleasant odors when staining,
  • creates a coating that can repel moisture,
  • prevents the processes of decay of the material.

After applying the antifungal primer, further surface treatment is performed. This includes puttying, applying plaster, paint, waterproofing materials, wallpapering, installation of tiles.

Primer is used to treat walls, floors and ceilings. It is especially important to protect the outer walls from the fungus, which are exposed to rain.

Surface preparation

Before surface treatment with an antiseptic, it must be prepared. If the fungus has already spread on the walls, then you must first remove it. To do this, apply whiteness or bleach, which are applied using a stiff brush.

After the bleach or other disinfectant solution has completely dried, priming can be carried out. Before coating, the surface is heated with a building hairdryer. As a result, the penetration of the antifungal agent for the walls will improve and its effect will last.

After work, all tools must be treated with disinfectants. This will prevent mold from spreading to other areas. When applying the material to a new surface or to prevent the appearance of mold, the work proceeds in the usual manner. The processed material should be dry, without peeling, greasy stains and other contaminants.

On the video: how to remove mold and fungus from the wall.

Work order

To apply the primer, you will need a roller, brush or spray. For small surface areas, it is better to use a roller. When using a brush, repair takes longer. Usually it is used for processing hard to reach places. For priming large areas against mold it is better to use a spray.

If you need to primer the surface in a residential building, then with the help of a roller, work will be much faster.

Antifungal treatment of walls includes several stages:

  1. Application of a primer.
  2. Primer drying.
  3. If necessary, applying a second layer of soil.
  4. After the primer has completely dried, the finish is done.

Work is carried out only at a positive ambient temperature. Additionally, protective equipment (gloves, respirator) should be used.

The interior and exterior are exposed to moisture, steam and temperature changes. Such an environment promotes the spread of various microbes. It harms human health, destroys building materials and spoils their decorative properties.

Antifungal agents exclude the appearance of fungus on ceilings and walls. The composition includes components that provide strong protection for building materials. The primer is selected depending on the type and condition of the surface. If an antifungal primer is used for walls, then other materials with priming properties are not used.

Danger of fungus and mold

Black spots on the ceiling and walls are found in rooms with high humidity. This is nothing like parasitic fungi. Neighborhood with them is fraught with unpleasant consequences. The unaesthetic appearance of the room is the smallest of them. Fungal spores can be harmful to human health, especially to sensitive children’s bodies. Respiratory organs serve as a conductor of spores in the body. The fungus is able to provoke a number of diseases, including severe ones.

Mycotoxins are harmful substances secreted by fungi. They 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 trigger black spots in a living room.

Like other parasites, getting rid of the fungus is quite difficult and time-consuming.

Causes of fungus

The formation of mold actively occurs subject to the presence of constant dampness. High moisture is a sign that should make you wary.

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

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

  • The use of "non-breathing" materials in wall decoration, lack of air circulation.
  • Pipe leakage.
  • Installing plastic windows leads to dew.
  • Violation of ventilation.

The defeat of the walls by the fungus accelerates their destruction. Getting rid of the existing fungus, as well as preventing its occurrence, is a priority task, for the solution of which there is an arsenal of funds.

Primer - mold control tool

The antifungal primer has a special composition developed by specialists with the aim of neutralizing fungal spores, preventing their return.

It is necessary to treat the surface with antifungal composition in the bathhouse, pool, bathroom, etc.

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

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

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

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

Varieties of Antifungal Primer

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 made with the inclusion of special substancespromoting film formation on the application surface. Varieties of glue, resinous, oil mixtures, substances that contribute to the rapid drying of the surface, antiseptic additives can give the primer properties that are designed to solve 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 a different composition of the type of primer. To effectively solve the problem of getting rid of mold, 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 compounds by 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.

The primers are diverse in their purpose. There are compositions for surfaces of metal, mineral, painted or with plaster, with laid ceramic tiles.

Antifungal Primer

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 spores of fungi and destroy the lesion completely:

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

  • With a solution of water and detergent (e.g. bleach), use a rag to wash off the black fungal stains from the surface of the walls or ceiling, after which the rag must be discarded, or better
  • to burn. This procedure is necessary so that the spores of the fungus do not spread throughout the room during further stages of work.
  • Dry the washed surface well, using heating devices or strong drafts.
  • Completely remove the infected area of ​​the plaster coating.

  • Using a blowtorch or gas torch, treat a surface area freed from plaster to dry and disinfect.
  • To clean the processed surface from a deposit and dust.
  • Apply a special antifungal primer to the surface.
  • After four hours, the surface may undergo a new finish (plastering, wallpapering, paint or tile).

Before working with any type of antifungal primer, you should carefully read the instructions for its use.

For applying a soil solution to small areas, a paint brush is used, on areas more harmful than size - a roller, on large surfaces - a spray. The primer should be even, with no spaces. For the best effect, the primer is applied more than once at the rate of ½ liter of composition per 1 square meter. The primer or antibacterial paint layers should be applied perpendicularly to one another correctly to avoid bald spots. The rubbing movements when applying antifungal agents will provide a deeper penetration of the composition into the treated surface.

If you strictly adhere to the above algorithm, you can achieve a good result in getting rid of the fungus.

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

An important rule is to observe safety measures when working with the fungus. Mold is dangerous to health, therefore, when disposing of it, it is necessary to use personal protective equipment: rubber gloves, adjacent glasses, a respirator, a hat, and tight clothing.

Avoid contact with exposed skin. If this still happened - immediately rinse them with running water.

Another immutable rule when detecting a fungus and the desire 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 the absence of sources of constant moisture even at the construction stage. This will require the organization of waterproofing in accordance with all the rules.

The house, which is not equipped on the outside with drainage trenches for discharging precipitation and groundwater, is at risk. The foundation, treated with a leveling base with an antifungal composition on the upper end or in its entirety, is the key to good waterproofing.

It is necessary before laying the brickwork on the foundation to lay the roofing material in two layers. This approach will prevent many potential problems.

At its cost, the primer from mold and fungus differs from simple formulations in a big way. However, the use of such a primer is significantly less costly than measures to get rid of mold stains that have arisen. Therefore, saving on mold primer is not practical.

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, as this material is subject to rapid destruction in adverse conditions.

Primer manufacturers

The following manufacturers of “fungal killers” enjoy constant popularity among specialists in the construction and repair profile:

  • Mill kill. The composition is able to penetrate the walls to a depth of three centimeters. Helps strengthen porous and fragile surfaces. Recommended for damp areas. 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. It has good black-hiding properties. Forms a film on the surface that prevents wetting.
  • "Area-Example". Acrylic based primer, contains fungicides of various types. It eliminates harmful bacteria and protects them from reactivation. It strengthens the work surface well and is comfortable in work due to the absence of a pungent odor.

  • Acryl Grundierung. Composition based on acrylic. Reduces the ability to absorb moisture in the application area.
  • Ceresit CT-99. The composition is high in concentration, while it is safe from an environmental point of view. It penetrates deep into the surface, retains its properties for a long time, applicable on internal and external surfaces.

An important factor when choosing an antifungal primer is that to prevent the formation of fungus and mold, you must choose a primer that meets the application conditions. To combat the existing colony of mushrooms, the use of a concentrate with a high content of fungicides is required.

Signs and causes of fungus formation

Impregnation from mold and fungus for concrete is used at the stage of repair and construction works. Nevertheless, for quality protection of the premises, it is necessary to study the causes of the appearance of the fungus and the "symptoms" of infection, which will help to avoid problems in the future and take into account all the nuances.

The main signs of the spread of microorganisms:

1. The appearance of dark gray or black, dark green spots and dots on the ceiling, walls, floor

2. Clearly noticeable raw musty aroma

3. Destruction of the external finish - the wallpaper peels off, the plaster layer falls off, the wooden panels move away from the base, the tile joints darken

4. Deterioration of general health due to the absence of any diseases - fatigue, poor sleep, headaches, decreased immunity, impaired attention and memory

The main causes of mold:

  • Poor protection of the base from moisture and cold, ignoring the need to lay thermal insulation, waterproofing
  • Poor processing of interpanel joints, as a result of which they freeze
  • Poor roof condition, freezing of the attic
  • Incorrect installation of window blocks, lack or poor operation of the ventilation system
  • Unprofessional performance of thermal insulation, as a result of which there is no normal vapor permeability
  • Unsatisfactory condition of plumbing - pipes are leaking, taps are leaking, water is sprayed when bathing, stagnates in crevices

Acryl grundierung - deep penetration composition

Based on acrylic, the consumption is about 1l / 15sq.m, it dries for 1 day, you can’t wear water-based paints on top of the layer, you can work at a temperature of +5 to + 35 ° C, it effectively fights fungus and bacteria, it provides good adhesion to the surface, it becomes An ideal choice for brick and concrete before applying paint and putty.

It does not interfere with air penetration, allows materials to breathe, positively influencing the indoor microclimate. Consumption of about 1l / 4-5 square meters, dries for 6 hours, you can paint the base only after 6 days.

The solution is highly effective against large volumes of the spread of microorganisms, does not change such surface properties as texture, gloss, color.

Conclusions and useful video on the topic

Fungus and mold are a problem that can never be ignored. And if you approach the issue seriously and take care of prevention, then in the future you can not only protect your health and loved ones from the negative effects of microorganisms, but also save the internal, external decoration of the premises, saving a lot. Prevention and timely treatment of surfaces using special modern means is a guarantee of safety and aesthetics.

Methods of struggle

Even if you recently made an expensive repair, new mold spots may appear in a fairly short period. At first, they notice a sharp unpleasant odor in the room, and mold spots appear only after some time. The structure of the fungus is soft and loose, it can be easily scraped off or cleaned with a metal brush. However, this will only help get rid of ugly spots, but will not solve the problem.

To achieve a successful result, it is recommended to carry out a whole range of works:

  • Stains of the fungus must be removed from the surfaces.
  • Affected areas should be treated with an antifungal primer.
  • If possible, you need to get rid of the elements where the mold could not be removed.
  • Ventilate the room well and adjust the humidity level indoors.

Types of Antiseptics

The primer is ordinary and antifungal. The first is aimed at preventing the appearance of mold, and the second is used to destroy fungal formations. In addition, antiseptics with antifungal additives have a longer effect and penetrate deep into the surface. The presence of fungicides in their composition helps to prevent the emergence of new microorganisms. In addition to the fact that these agents remove the fungus, they are characterized by excellent antiseptic and antibacterial properties.

Antiseptics are:

  • water soluble
  • combined (in the form of a concentrate),
  • oily
  • based on organic solvents.

There is also a difference in the composition of the primers. Consider the differences of each species separately.

Acrylic based

They contain acrylic resins that help improve the adhesion of the material. They are considered one of the most harmless, do not contain any dangerous substances and dry in a short period of time. Suitable for application on walls and ceilings in bathrooms, kitchens, pools, basements and facade processing.

Based on quartz

The base of this primer is sand, so after application the layer turns out to be slightly rough, due to which the adhesion of materials increases. Such a solution is applied immediately before painting or applying decorative plaster.

Mineral

The composition of the mineral primer has gypsum and cement. It is optimally suited for use on brick and concrete surfaces. It is used only after the walls have been plastered and covered with silicate materials.

Mineral primer is also completely harmless to the human body., since its composition includes natural substances. It differs in quick drying - about 2 hours.

Alkyd

This primer is used to treat wooden surfaces. Promotes long-term preservation of wood and prevents the growth of fungus. There are varieties of alkyd compounds for steel, glass and tile surfaces. You should be aware that such solutions are not suitable for application on plastered floors and gypsum board walls. It will take about 12 hours to fully dry.

Before you purchase a particular tool, you should read the instructions, because some of them are aimed only at the prevention of fungus and are not designed to completely eliminate bacteria. Also, when choosing, you should consider the material on which it will be applied.

To achieve maximum results, you need to select a solution for a specific type of surface.

The primer can be used for the following materials:

  • concrete,
  • tree,
  • brick,
  • putty,
  • drywall
  • gypsum plaster
  • expanded polystyrene,
  • cement plaster.

Range

Today, the building materials market offers a wide selection of primers designed to combat fungus, moss and mold.

  • One of the most popular solutions is concentrate. Ceresit ct99. It does not emit odor and harmful substances, moreover, it is absolutely safe for the human body. Suitable for application to internal and external surfaces of a building, carrying out preventive measures and direct stain removal.

The maximum effect is achieved when used on porous surfaces (concrete, brick). The concentrate is recommended to be used in diluted form, observing a proportion of 1: 2 or 1: 5, based on the condition of the affected areas.

  • An equally effective tool is an antiseptic primer Biostop. It is used for the prevention of cold walls made of brick, concrete and other building materials with a porous structure. You need to apply the product on a previously dried and fat-free surface. Penetrating deep into the walls, the solution blocks the further reproduction of fungal spores.
  • Many consumers respond well to the primer. Milkill which prevents the formation of new mold areas. It is applied in two layers, it will take from 24 to 48 hours to dry. This composition helps to increase the adhesion of the walls, thereby preventing the penetration of moisture into the material. Suitable for the prevention and elimination of fungal formations.
  • The primer received positive reviews. Mapei, used for interior and exterior walls. It, like the previous material, has prophylactic properties and is a rather effective remedy against overgrown moss.

  • Primer Sniezka It is very popular among professional builders. She is chosen for getting a quick result and lasting effect. It can protect against mold spores, fungus, lichen, yeast, and even algae. Before application, the composition is diluted with water.
  • Often on the shelves you can find an insulating primer Elegant 296. It can be used on any surface and protects the substrate well against moisture. It has excellent coloring properties: it can paint over even strong black spots.
  • Acrylic primer “Area-Example” It is made on the basis of effective fungicides, due to which it is not easy to eliminate harmful microorganisms, but also blocks their re-formation. In addition, it has antiseptic properties and can be used to strengthen the outer layer of walls.

  • Among the analog products, another acrylic primer can be distinguished - Acryl grundierung. It forms a protective layer, blocking the absorption of moisture into the surface of walls and ceilings. Its popularity is ensured by affordable cost and high quality.
  • One of the effective domestic means - "Anti-mold." It is an antifungal concentrate that is suitable for treating interior walls and building facades. It well eliminates all organic formations: moss, mold, fungus, shoots, algae, blue.

Experts recommend using the tool at all stages of construction. The product is environmentally friendly, odorless, does not change the decorative properties of the material on which it was applied.

Application Tips

Regardless of which primer you choose, apply it directly to the affected areas. Knowing some of the nuances of using compounds against the fungus, it will be easier to achieve a positive result.

  • The primer must be applied to the previously cleaned and dried wall. You can wash off the mold using the "White" diluted water. Even if there are no spots left on the surface, this does not mean that you have got rid of them. For more effective removal, you can walk around the site with a construction hairdryer or blowtorch.
  • It is necessary to properly ventilate the room. The bathroom has a fan or convector. Other rooms open wide windows, creating a draft.

  • Before applying the antifungal, you can not treat the surface with a normal primer. They form a film, thereby blocking the penetration of antifungal compounds into the walls. In this case, their use will be pointless.
  • It is necessary to carry out processing in dry rooms, preferably in the warm season.
  • The primer should be applied with a brush, roller or aerosol. The most effective will be the use of brushes with natural bristles - this will apply the composition even in hard to reach places.
  • During the use of antifungal agents, safety measures must be observed. All work is carried out in protective clothing, a respirator and rubber gloves.
