One of the main components of a good repair is the decoration of the room, so it should be carried out exclusively by effective and high-quality means. This should include a primer, the use of which is almost always mandatory. Usually, a primer is used on loose and not sufficiently dense walls. It is possible to strengthen materials with its help due to the presence in the composition of the binder component with microscopic particles.
What surfaces can be applied
When applying the mixture, the composition penetrates inside and begins to glue the material, making it more durable. After the layer dries, the wall acquires a protective film, which prevents the penetration of moisture into the interior. The primer is well suited for the following substrates:
- drywall;
- foam concrete;
- plaster;
- wood;
- aerated concrete;
- brick.
Basic properties
Antifungal primer has some properties, among them can be distinguished:
- lack of frost resistance;
- security;
- impressive penetration depth;
- wide range of operating temperatures;
- antiseptic properties.
The primer has a white, milky or colorless hue. One cannot but mention security. The primer is not toxic, explosive or fire hazard. The penetration depth will depend on the degree of porosity of the material and can reach 10 mm.
Drying time
The composition has particles with the largest size of 0.05 microns. When applying several layers, you must remember that between them should be kept for 1 hour. During this time, the primer should dry. Further actions can be carried out only after 1 day. The air temperature should be 20 ° C or higher. Humidity cannot be less than 60%.
Manufacturers Overview
Antifungal primers are made by many manufacturers. The cost of the material will depend not only on the composition, but also on the basis, it can be:
The main ingredients are fungicides that destroy microorganisms and prevent their reappearance. Such primers are often called antibacterial or antiseptic. You can choose the composition depending on the type of surface. Universal primers are available on the market, but the greatest effect can be achieved by selecting the material under the base of the surface.
Universal antifungal primer can be applied to:
- wood;
- brick;
- concrete;
- polystyrene foam;
- drywall;
- plastered with cement mortar surface.
The deep penetration primer is a mixture of Milkill, which is represented by a latex emulsion. The composition contains antimicrobial substances. Suitable primer for the treatment of finely porous and slightly absorbent surfaces. Application in two to three layers is recommended. The basis may be brick or concrete. Humidity in the room during operation can be increased.
Another antifungal primer is Acryl Grundierung, which is made on an acrylic basis. It reduces the absorption of the surface and penetrates well. The mixture has antibacterial properties. Typically, the compositions are used to prevent the appearance of microorganisms.
If the surface is already contaminated, it is best to use a more concentrated type of mixture to kill mold and fungi. This tool is Ceresit CT 99. With this concentrate you can fight lichens, mold, moss and fungi.
The composition is environmentally friendly, has a long-lasting effect and has the ability to penetrate deeply inside. You can use it not only inside, but also outside the premises. This deep penetration antifungal primer can be applied to plaster, brick or concrete. You can buy it in liter bottles. The concentrate should be diluted with water before use.

- long action;
- deep penetration;
- the possibility of staining;
- lack of heavy metals;
- environmental safety.
The mixture must be diluted with water in a ratio of 1 to 2 to 1 to 5. Consumers emphasize that this product fights well not only with mold and fungus, but also with microorganisms like bacteria and algae. Application can be carried out on any mineral base.
Consumers like that “Ceresit” has fungistatic properties, which are expressed in an obstacle to the development of new organisms from spores.
Milkill Primer Properties, Performance and Reviews
This antifungal primer is universal. It has a murky white color, which is obtained by adding antimicrobial substances. The emulsion will penetrate the material at 5 cm maximum. A thin film remains on the surface, which will facilitate adhesion to other materials. The film, according to consumers, does not prevent the walls from breathing and protects against moisture and vapor.
When applying Milkill antifungal primer in one coat, the flow rate will be about 300 g / m 2 . Drying time - a period from half an hour to an hour. Within 24 hours, the layer becomes operational. The final drying time will depend on the environmental conditions.
Extra features
This deep penetration antifungal primer on concrete can be applied with a spray gun, roller or brush. The temperature should not fall below + 5 ° C. Dilution before application is not required. Consumers sometimes express dissatisfaction with the fact that this composition is quite expensive. But in his favor it can be said that universal emulsions are cheaper than specialized ones.
Instructions for use
The antifungal primer for the bathroom should be applied to a cleaned and well-dried surface. It is necessary to wash off a mold well with warm water, having previously added "White" to it. The fungus penetrates deep into the plaster. Getting rid of black spots, you can not be sure that the fungus is completely destroyed. If you want to achieve a good effect, then a brick or plastered surface must first be treated with a blowtorch. Instead, you can use a regular building hair dryer.
After cleaning the surface, you can dry it and ventilate the room well, do not rush. When it comes to the bathroom, you can use a fan or a heat convector. When work is carried out in a room where it is possible to draft, it is necessary to open the doors and windows, directing the air flow from the fan heater to the affected surface. The usual primer for loose surfaces can not be used before applying the antifungal primer. Such compositions form a film on the surface, so the antifungal effect in this case should not be expected. It is necessary to work in a dry room. It is best to carry out manipulations in the summer.
Antifungal primer for walls is applied in one of the above ways. The greatest effect can be achieved using a brush with natural bristles. With its help you will process hard-to-reach spots. It is important to observe safety measures, for this rubber gloves, a respirator and tight clothing are used.
Wood processing technology
If white plaque appears on the wood, which gradually changes appearance, you can be sure that a fungus has appeared on the base. It can take the form of a white gun and or a gray film. Under the influence of the fungus, the material begins to acquire a gray color, and eventually crumbles. The fungus multiplies quite quickly in the wood. In one year, it can completely collapse. Soft rocks, which have a low density, are particularly affected.
Before applying a deep penetration primer with an antifungal effect, it is necessary to clean the infected area by removing the fungus with a knife with a metal brush. Sawdust should not be buried in the garden, they need to be burned. Tools are then washed with water so that the fungus is not transferred to other areas. The cleaned places are washed with detergents with the addition of peroxide, after which they are left until dry. Vinegar, copper sulfate or baking soda can be added to the water.
Unprocessed wood cannot be used for bath decoration. A disease is easier to prevent than to cure. Damage to wood can be considered as a disease. German-made Dufa-Holzlasur primer is excellent for protection. Glaze is for wood. The tool provides protection and protects against mold and mildew. A liter will be enough to handle 10 m 2 .
Reviews on some types of primer
Antifungal primer for concrete can be made on the basis of quartz. There is sand in the composition. According to consumers, it is well suited to improve adhesion if the walls are finished with plaster or paint. Customers love the safety at the time of use and operation. The surface before applying the primer must be moistened. Another type of anti-fungal agent is a mineral primer. It is suitable not only for concrete, but also for brick. The wall is dry after 2 hours after application. The bonding component is cement.
The primer may be alkyd. Based on zinc chromate and phosphorus. This material eliminates the appearance of rusty particles on the surface. Buyers say that this mixture is best used for processing the following types of surfaces:
- ceramics;
- metal;
- glass;
- wood.
Application excluded on concrete or drywall.
Finally
Ceresit antifungal primer is one of the most popular today. It costs a little more than analogs, but differs in outstanding characteristics. It is noteworthy that this tool is sold in the form of a concentrate. This means that the mixture is enough for a long time. You can choose the proportion for dilution yourself. The composition is suitable not only for external but also for internal work, which expands the scope of use.
When applying such products, it is important to observe safety measures when using personal protective equipment. This should include a respirator, gloves, and appropriate clothing.
Surface pretreatment will not be enough. This indicates that in addition to antiseptics before applying the primer, it is necessary to treat the base with a high temperature.
