Antifungal primer protects against mold

Priming the surface is one of the important and critical stages of work, preceding the finishing. The composition for it should be selected taking into account the base material and the operating conditions of the surface being trimmed.
In this article, we will talk about what an antifungal primer is, when it is applied and how it is applied.

What you need to know about mold and fungi

We all know what mushrooms are, many more than once they collected them in the forest with their own hands. Mold is also a variation of this culture.
It can be useful and used to produce antibiotics or to improve the palatability of cheese and some other products. And it can cause irreparable harm to both your housing and health.

What is dangerous mold

Mold fungus is a living organism that produces microtoxins that are harmful to human health.. Under favorable conditions, mold spores multiply very quickly, destroying the surface on which they exist.
They cause not only a common cold or allergy in people constantly living in such a room, but also serious diseases such as:

• Decreased immunity and performance;
• Bronchitis;
• Otitis;
• Bronchial asthma;
• Rhinitis;
• Migraine;
• Violations of the cardiovascular system;
• Acute poisoning (mycotoxicosis);
• Oncological diseases;
• Mold lesions of internal organs.

Moreover, a person may not suspect a cause of malaise if the mold is hiding under the floor or under the skin exterior wallsuntil it expands and affects visible structures. But time will be lost: not only have to be seriously treated, but also engaged in major repairs.

It is very difficult to deal with this phenomenon - fungal spores penetrate deep into the structure of the material. Having cleaned the surface, you will not achieve the desired effect, and after a while they will sprout again.
It is much easier to prevent the emergence of this scourge, clearly observing the construction technology, performing preventive measures during the operation of the room and using a special tool during the repair, which is an antifungal primer for walls (seePrimer consumption per 1 m2 - approximate data for determining the required volume).

How to prevent mold

Ideal conditions for the growth of mold are increased humidity and limited air movement - in other words, poor ventilation. In order to prevent its formation, these factors should be excluded.
To do this, you must:

• Monitor the condition of plumbing and sewer systems, repair them in time, eliminate leaks;
• During construction, to fulfill all the requirements for the construction of not only waterproofing, but also thermal insulation, since the fungus can settle in the walls that freeze and then thaw and accumulate moisture;
• It is good to close all joints between elements of supporting structures, excluding cold bridges;
• Provide adequate ventilation in the rooms. This is especially true for wet and unheated rooms - kitchens, bathrooms, closed loggias, verandas, etc.

The instruction requires a mandatory exhaust ventilation device in wet rooms

• To ensure the impregnation of structures at risk of damage by fungus, fungicidal (antiseptic) compounds.

All about fungicidal primers

Fungicides are active substances that destroy fungal spores. They can be added to various building mixtures and compositions to protect the finished structures from mold.

Types of Antifungal Primers

Construction soil is made on an acrylic, mineral, alkyd or other basis, and is selected in accordance with the type of surface to be treated.

For reference. The most popular are universal deep penetration primers suitable for various surfaces - wood, concrete, plaster, brick, drywall, expanded polystyrene, etc.

When fungicides are added to the primer, it acquires additional properties - it destroys harmful microorganisms and prevents their appearance.
Such mold and mildew primer can be normal or concentrated:

• The usual antiseptic primer is used to prevent and prevent mold and is applied to new or not affected by microorganisms surfaces;
• The concentrated antifungal primer is intended for the treatment of surfaces infected with fungus. It penetrates deep into the structure of the material, has a long-lasting effect and helps to fight even with moss and lichens.

Concentrated primer against fungus and mold Ceresite CT99

Note. Acrylic concentrated primer for preventive treatment of walls can be diluted with water.

Rules and methods of application

If mold and mildew primer is applied as a preventive measure, then this is done in the usual way, as with standard priming before subsequent finishing. Basic requirements for the surface: it must be dry, without exfoliating areas, dirt and grease stains. In the video, this process is described in sufficient detail.
If processing of already infected structures is required, then the following requirements must be met:

• To clean the surface of mold, using scrapers and warm water with the addition of chlorine-based products, such as whiteness;

Tip. All tools used for cleaning should be washed and disinfected after completion of work to avoid contamination of other areas.

Mechanical surface cleaning

• Since the spores penetrate deep into the material, the surface removal of the mold does not guarantee its complete extermination, therefore it is advisable to influence the infected areas with high temperatures. In the case of wood and other combustible materials, you can use a building hair dryer, and burn brick or concrete walls with a blowtorch;
• Having cleaned and dried the surface, care should also be taken to remove excess moisture from the room. To do this, it is well ventilated, and if this is not possible - use fan heaters and convectors.

Only then can a mold and fungus primer be applied to walls and other surfaces. This is done in any convenient way - using a roller, brush or spray gun.
Work should be carried out only with positive values ​​of the ambient temperature and only with the use of protective equipment - rubber gloves, a respirator, goggles. This is an important condition, since fungicidal additives are harmful to health.

The processing of moldy walls

Note! Walls should not be primed with conventional compositions to strengthen their surface before antiseptic treatment! The primer with an antifungal effect will not penetrate the formed strong film, and all spores will remain in the thickness of the wall, and will continue to multiply.

Particular attention should be paid to the processing of wooden structures (seePrimer wood - process features) They are more susceptible to mold destruction than others, under favorable conditions for it, this can happen literally in a year. It is desirable to remove the upper most affected layer from the wood, which then needs to be burned.

Conclusion

The primer for walls is antifungal - this is not a panacea. If during the construction or operation of the building the technological requirements are not met, if the surface constantly dries and does not dry out, sooner or later the fungus will still appear.
But with the help of this tool you can minimize the risk of its occurrence. After all, situations such as leaks from the roof, a breakthrough of a water supply system or a flood from neighbors from above are far from uncommon.
The price of even the most expensive antiseptic primer is not comparable with the damage that the fungus can cause to your home and health.
