Anti-mildew and mildew primer

How to apply the primer correctly

In order for the protection to be as effective as possible, the application rules should be followed. The technique is different for different types of formulations, but there is a general algorithm that should be followed.

Surface preparation

The preparatory phase is important, especially when working with an infected surface. First of all, you need to remove the mold with a rag dipped in whiteness. The rag must be burned to stop the spores from spreading. Dry the treated surface. Then the damaged plastered area is removed. Dry and disinfect the surface with a burner. Next, carbon deposits and dust are removed, after which an antifungal primer is applied.

Application methods

Important! When covering walls with soil, do not neglect the rules of protection. Use personal protective equipment: full body clothing, gloves, respirator, goggles

Reasons for the appearance

First, let's understand the concepts. Mold is a fungus that has several varieties. Develops by air spores. This is how we see her with the eye:

Conventionally (for the layman) can be divided into useful and dangerous. Useful ones are used for the production of food products (some types of cheese, wine, citric acid, etc.), medicines (penicillin, etc.). Dangerous ... it's a long time to enumerate here.

The main reasons for the aging of fungal mold are humidity over 60% and insufficient ventilation. The rationale for this may be different:

• - walls with poor vapor permeability;
• - errors in repair;
• - leaking plumbing;
• - wrong decisions at the construction stage.

The list is long, but the main thing is named.

And this is under the microscope. Fantastic! Space! Aliens!

When antifungal treatment is carried out: conditions

In view of the great danger of the development of fungal colonies in the premises, the treatment is carried out immediately:

• When visible signs of damage are found - the appearance of plaque, mucus, blackening of the surface.
• After the elimination of emergencies associated with water flooding or sewerage breakthrough.
• With a systematic deterioration in the well-being of people in the room.

Preventive treatment is carried out:

• During the renovation of the premises.
• During general cleaning.
• Before and after the heating season.

To increase the effect of using fungicides and disinfectants against mold, it is recommended to additionally process the walls of the bathroom and toilet at least once a week.

Work order

The primer can be applied with a roller, spray or brush. With the first tool, a small area is processed, the second is suitable for large surfaces, and the third is used for penetrating hard-to-reach places.

Processing stages:

• distribution of the primer over the surface;
• applying a second layer (if necessary and only after the previous one has dried);
• finishing finish.

The primer is selected taking into account the type of surface. When processing, for example, walls, a compound intended exclusively for this purpose is used.

Antifungal primers are irreplaceable helpers in the fight against mold. To avoid the appearance of fungal colonies, you should regularly carry out the treatment with the means described above.

Treatment with an antifungal primer, instructions for use

The materials are applied directly to the affected areas. But you do not need to apply the substance specifically to the spots. It is recommended to rinse the surface in advance to clean it. For this, chlorine is used, and then they resort to further processing.

The materials are applied directly to the affected areas.

Surface preparation and additional tips

The action of the primers increases over time if you take care of the preliminary processing of the walls. After weathering and drying, the use of soldering irons or hair dryers is allowed so that the treatment gives a result.

Other recommendations from specialists are as follows:

• Cleaning and pre-drying the walls is mandatory, as already mentioned;
• Simply clean the mold with whiteness diluted with water. But do not completely calm down, even if the spots are no longer visible. Cleaning with a construction hairdryer, blowtorch is faster. But it is better not to use this method under the wallpaper;
• Ventilation of the premises is obligatory. Convectors or fans do this job inside bathrooms. Under other circumstances, the windows are wide open, creating drafts;
• Do not apply a regular primer before using the antifungal. After all, other materials form protective films that prevent the penetration of not only harmful microorganisms, but also useful substances;
• Maintaining dryness in the premises, warm time - optimal conditions for work;
• Aerosols, brushes and rollers are of the best quality for the craftsman. Especially in the presence of bristles with natural fibers. Thanks to this method, the composition is applied even in hard-to-reach places.
• Compliance with safety measures is mandatory during work. Even if the tree is being processed.

Maintaining dryness in the premises, warm time are optimal conditions for work.

Work order

Distributing the composition over the surface, take rollers or brushes, sprayers. The roller is compatible with small areas. The brush complicates repair work, but allows you to easily reach hard-to-reach places. The sprayer is taken if the treatment area is really large.

Several stages are included in the anti-fungal treatment:

1. Application of a layer with an antifungal wall primer.
2. Wait a while until everything is dry.
3. If necessary, apply a second layer.
4. Finish after complete drying.

The preservation of a positive temperature by the environment is the main condition for successful work. Negative factors persist in the same way when decorating inside and outside. When using antifungal agents, protection against harmful microorganisms is simplified. The choice of which type of antifungal soil to use in a particular case is determined by the type and condition of the surface.

The brush complicates repair work, but allows you to easily reach hard-to-reach places.

Working with an 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 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).

To apply the soil solution to small areas, a paint brush is used, to areas of a harmful size - a roller, on large surfaces - a spray gun. The primer layer should 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 the observance of 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.

Antifungal primer - purpose, properties and application

Manufacturers offer a wide range of proposals against fungi, but each product has its own parameters. Keep in mind that only professional options are designed for deep sanitation of surfaces and complete elimination of mold. Most of the proposals provide only effective prevention. Antifungal wall primer is usually applied after the damaged plaster has been completely removed from the load-bearing surface of the building. This is done in order to create a barrier between the masonry and the new layer of plaster - preferably cement-lime.

Building mixtures are usually not recyclable. Only clay damaged by the fungus can be used repeatedly, and subject to the application of a solution made with the addition of lime. Lime and clay can help get rid of the problem.If the plaster is applied on a wooden base of an adobe, frame or timber house, it is recommended to pre-paint the surfaces with a self-prepared sanitizing liquid based on copper sulfate.

Manufacturers offer many different mixtures against fungus

All antifungal agents contain fungicides and a base that creates a barrier (acrylic, mineral, alkyd, latex, etc.). For efficiency, a disinfecting composition is used that provides both antibacterial and antiseptic protection. The difference between antiseptics and fungicides is that the former provide short-term sanitation, the latter - long-term. The anti-mildew properties of a liquid coating depend on the amount and penetration of certain anti-fungal agents.

Depending on the purpose and the substances used for the preparation of the antifungal primer, the purpose, properties and application may vary. For example, some products are used for surface treatment of areas affected by mold, others provide reliable protection for a new layer of plaster. Depending on the base used, concrete, brick, polystyrene bases, fine-porous and large-porous materials can be processed.

Choose funds based on the characteristics of the affected area

Types of antiseptics by composition

A wide range of priming antiseptic compositions allows you to use finishing materials for finishing work without restrictions. Specially developed formulations help to significantly strengthen the base, making it resistant to mechanical, chemical and biological destruction. On the ground-treated base, the finishing material lays down evenly, while it is consumed sparingly.

Acrylic based

Acrylic antiseptic priming solutions are universal in use, suitable for processing a wide range of materials. Their difference is a high level of absorption and quick drying. The primer particles penetrate into the substrate to a depth of 10 mm.

It is recommended to use acrylic compounds to prepare the surface for wallpapering. This reduces the consumption of adhesive, improves the quality of the sticker and makes it easier to dismantle in the future.

Quartz based

A quartz-based primer consists of acrylic resins and fine sand particles. It serves as a base coat for applying embossed finishing materials: mineral stone, fiber facade, fiber stone, unikvartz, etc. This type of primer is used on concrete, brick, plasterboard surfaces. The quartz composition can be applied to plaster and cement. It strengthens the base, improves adhesion and reduces the consumption of finishing materials.

Mineral

Mineral primer is used to strengthen and hydrophobize light mineral building materials: limestone, plasters, porous substrates. The composition gives the surface the following properties:

• evens out the absorbency;
• forms good vapor permeability;
• significantly strengthens the structure;
• protects against negative external factors;
• increases resistance to biological destruction;
• increases resistance to ultraviolet radiation.

This product works well with silicate paint.

Alkyd

Alkyd primers are used to treat wood and metal surfaces. The composition strengthens the structure of the base, prevents damage by fungi, putrefactive bacteria, woodworms, mold.

Alkyd mixtures are well combined with PVA, paints based on nitro compounds, acrylic putty and paint and varnish products based on alkyds. This type of soil is unacceptable for treating surfaces with a shedding property: gypsum, plaster, etc.

Anti-mildew antiseptic deep penetration primer

This product is intended for impregnating surfaces with high porosity.Particles of the solution penetrate to a depth of 10 mm, strengthening the base, increasing its adhesion and preventing the development of harmful microorganisms. Main technical indicators:

• penetration depth - 5-10 mm;
• consumption 50-300 g / m2;
• drying time at room temperature - 1-3 hours;
• working temperatures - 5-30 ⁰С;
• operating temperature - 40-60⁰С.

The composition of the deep penetration primer can be acrylic, silicone, alkyd, polyvinyl acetate, epoxy. In addition, there are polystyrene, shellac, silicate, latex and water-dispersion impregnations. Each of the compositions is recommended to manufacturers for processing a specific type of surface.

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

Primer - a tool for fighting mold

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 into 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, ground solutions with a higher concentration of antiseptic substances and penetrating ability are used.

Danger of mold and mildew

Mold usually appears where there is moisture, steam, or strong temperature fluctuations on concrete substrates. In living quarters, these are bathrooms, bathrooms, kitchens, rooms where heating is not turned on constantly, etc. All surfaces where there is a risk of the spread of microorganisms, it is better to treat prophylactically, without waiting for a problem to appear.

After all, fungus and mold are very dangerous for health - they release mycotoxins, their spores spread by airborne droplets, quickly enter the respiratory organs, provoking a number of health problems: chronic fatigue, decreased immunity, allergic reactions, migraines, diathesis, bronchitis, asthma, rhinitis , otitis media. In cases of severe infection, even problems in the work of the cardiovascular system, irreversible damage to internal organs, and oncological diseases are possible.

In addition, spores penetrate deep into the material and the fungus quickly destroys the surface on which it appears. And literally a few months after the first dark spots appear, the finish becomes loose, peels off freely, collapses and literally burns out.

It is extremely difficult to get rid of the fungus - in the process of treating the surface, you must carefully follow the safety rules, immediately wash all clothes, use special tools and means to prevent the spread of flying invisible spores further through the dwelling, and prevent them from entering the respiratory tract. It is much easier and safer to immediately process substrates in rooms with high humidity, so as not to leave the parasite a chance.

Causes and signs of fungus formation

It is difficult to ignore the external signs of a room's disease with molds:

• spots of black, gray or dark green appear on the walls, ceiling or floor;
• there is a smell of dampness in the room;
• the inter-tile seams on the tiles in the bathroom become dark;
• the destruction of structures begins: wallpaper peels off, plaster falls, brickwork crumbles.

The causes of damage by microorganisms in most cases are similar and are associated with waterlogging of building materials inside or outside the building:

• poor-quality waterproofing of surfaces when water penetrates into structures;
• freezing of the walls, due to which moisture accumulates inside;
• poorly executed insulation of joints between wall panels;
• roof leaks or cold attic;
• wooden floors of the first floor of the building, when there is a subgrade under the covering;
• poor ventilation in rooms with high humidity (bathrooms, saunas, swimming pools).

Emulsions

The most widespread today are the following compositions:

• Ceresit CT 99: characterized by a long exposure time. This composition is environmentally friendly and suitable for treatment both inside and outside buildings. Can be applied to concrete and brick.
• ABEDIS 06: used to remove organic plaque. This type of product is applied to brick walls, surfaces covered with plaster or ceramic tiles. Used for preventive purposes.
• Dali is a versatile anti-mold and mildew primer with antiseptic properties. It can be used for preventive purposes before painting surfaces. It is applied on concrete and brick substrates.
• Fongifluid Alpa is used both for eliminating lesions and for prophylactic purposes. The product is suitable for processing brick and wood surfaces, ceramic tiles, drywall, cement and plaster. This concentrate provides air access to the material, which has a beneficial effect on the overall microclimate in the room.

These special tools allow you to eliminate fungal foci. The most popular are the following:

1. Ceresit CT 99 - has a long-lasting effect. An environmentally friendly concentrate suitable for the treatment of 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 paths. Used for prophylaxis.
3. Dali is a universal antiseptic. Used as a preventive measure before painting, to remove existing mold. It is applied on concrete, brick and plaster substrates.
4. Fongifluid Alpa - "treatment" and prevention. Destroys existing lesions and prevents re-infection. The tool is used to treat wood and brick surfaces, drywall and ceramic tiles, tiles and cement plaster. The concentrate does not interfere with the penetration of air to the materials, which has a positive effect on the microclimate in the room.

Types of antiseptics

The primer is normal 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 lasting effect and penetrate deeply into the surface. The presence of fungicides in their composition prevents the appearance of new microorganisms. In addition to the fact that these funds remove fungus, they are characterized by excellent antiseptic and antibacterial properties.

Antiseptics are:

• water-soluble;
• combined (in the form of a concentrate);
• oil;
• based on organic solvents.

There is also a difference in the composition of the primers. Let's consider the differences of each type separately.

Acrylic based

They contain acrylic resins, which improve the adhesion of the material. They are considered one of the most harmless, do not contain any hazardous substances and dry in a short period of time. Suitable for walls and ceilings in bathrooms, kitchens, swimming pools, basements and facades.

Quartz based

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

Mineral

The mineral primer contains gypsum and cement. It is ideal 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 it contains natural substances. Differs in fast drying - about 2 hours.

Alkyd

This primer is used for treating 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 to plastered floors and drywall walls. It will take about 12 hours to dry completely.

Before purchasing this or that remedy, you should read the instructions, because some of them are aimed only at preventing fungus and are not designed to completely eliminate bacteria. Also, when choosing, you should take into account the material on which it will be applied.

You can use a primer for the following materials:

• concrete;
• wood;
• brick;
• putty;
• drywall;
• gypsum plaster;
• expanded polystyrene;
• cement plaster.

What types are there

Choose a primer based on the material of the base (wall), purpose and type of subsequent finishing. Let's consider all types in more detail.

Acrylic deep penetration

The white translucent deep-penetrating solution has no unpleasant odor and dries quickly.

One of the most commonly used type of wall primer. The penetrating universal acrylic-based compound removes dust from the surface, strengthens old and loose plasters, improves adhesion, slightly reduces the water absorption of walls and ceilings and thereby prevents moisture from leaving the applied plasters.

Consumption largely depends on the porosity of the walls, on average 100-200 g per square meter.

Ingredients: water and acrylic polymers. Antibacterial and antifungal components may also be present

It is important to pay attention to the amount of dry residue in the composition of the acrylic solution. In good primers for walls, this value should be less than 10%, in floor materials - 15%

The solution dries up in 2.5-3 hours.

Manufacturers: Ceresit CT 17, Unis, Prospectors, Optimist, Bolars, Lacra, etc.

Adhesive quartz-primer of the "betonokontakt" type

The concrete contact significantly improves the adhesion of the wall and finishing materials. The dye in the primer helps to control the uniformity of the application.

Betonokontakt is an excellent option to improve the adhesion of concrete and any sheet materials: drywall, fiberboard, chipboard, OSB boards before applying gypsum or decorative plaster.

Primer composition: acrylic dispersion (more concentrated than universal), quartz sand, dyes.

After the concrete contact dries, the wall or ceiling becomes rough due to the applied sand. Thanks to this, even smooth surfaces, including painted walls, can be plastered or tiled.

Consumption: 200-300 g per 1m2 when applied with a roller.

Producers: Ceresit CT 19, Alpina Expert Quartz-primer, KNAUF Betokontakt, Farbe, Tex, etc.

Anti-mildew and mildew primer

Anti-mildew soil

Serves for antifungal and antibacterial protection of wood, as well as for treating walls in damp rooms and basements.

Antifungal primers are made on the basis of universal acrylic with the addition of an antiseptic. Therefore, they have the same technical characteristics: consumption and drying time.

Examples of manufacturers: Alpina Expert Bio-Stop, ECOTERRA, Gunstig, Lakra, Areal, etc.

Alkyd (glyphtene)

Alkyd primer

It is mainly used to protect metal from rust, wood from decay. Also, GF-primer is used on surfaces made of plastic, chipboard, fiberboard, glass or fiberglass as an intermediate layer before painting.

Alkyd compounds are applied in any convenient way - with a roller, brush, spray. Dilution of the solution with white spirit is allowed.

Consumption: 100 g / m2. Drying time is 24 hours.

Examples of manufacturers: Otex, Lakra, Tex GF-021, TURY.

Silicate

Suitable for sand-lime bricks, concrete, cement-sand and lime plaster.

Consumption when applied in one layer is 200-250 g per m2.

Producers: Caparol Sylitol-Minera, Derufa Silicate Primer, Ceresit CT 15.
