How to choose an antiseptic to protect concrete from mold?

Very often we hear this view: mold is not capable of destroying concrete, so there is no need to actively fight against it, and antiseptic for concrete from mold is not needed. This understanding of the problem is wrong. Mold does not harm concrete, but fungal colonies reproduce well on it, posing a threat to human health. Even fungi, molds - the cause of food spoilage, and with them, controversy can again penetrate the human body. Therefore, it is imperative to get rid of parasitic microorganisms. And this struggle will be successful if you choose the right antiseptic for concrete from mold.

Fungi multiply very quickly in wetrooms when the temperature rises above 26 ° C. They especially like joints of concrete slabs, combined concrete-wooden surfaces. Therefore, the processing of concrete in industrial, residential areas is required before they begin to finish. If the fungi have already formed a colony (dark green, black formations are visible on the surface), they should be removed with the same antiseptic bio-compositions. And here one should take very seriously the process of diluting the composition, take into account the brand of concrete, the density, the complexity of the problem, and choose the right type of antiseptic. If there are some not very good reviews about some kind of means - this does not mean that it is bad: it was picked up to the wrong concrete, it was incorrectly diluted.

To form molds, special conditions are necessary

Features of antiseptics

Choosing the right composition - the most difficult moment. After all, there is no universal remedy that would suit in any case, to any concrete, type of microorganisms. Very often, the funds have absolutely no effect on which the consumer expects, precisely because of the wrong selection. The ideal option is to choose a remedy for mold / mildew, which has a wide range of effects with a biocidal effect of disinfection. Such tools must have a penetration of at least 1.5 meters, and they are applied to the concrete before applying the finishing compositions. The main groups of antiseptics are four:

  • complex;
  • water soluble;
  • organic;
  • oil.

  • For the prevention of fungus, concrete walls are treated with antifungal antiseptic

    Characteristics of funds by type

    Complex (or combined) means notthey simply destroy the fungal / mold colonies, they “heal” the surface, continue to protect it for a long time after application. Even if the fungal spores remain, these antiseptics will not allow them to develop, which will lead to their death over time. The compositions of these tools are complex, with multidirectional action of each element. They are sold in the form of concentrated mixtures, which should be diluted, strictly following the instructions. For internal work, a comprehensive antiseptic for concrete from mold is the right choice to choose. After all, it should be characterized not only by efficiency, prolonged action, but also by safety for people. Any antiseptic is toxic (to varying degrees). Apply it should be protecting hands, respiratory organs, face. After treatment, the room should be ventilated for a long time until the odor is completely weathered.

    Water-soluble antiseptics due to the contentmineral salts are dangerous to the metal, that is, destroy it. Almost all products of this group are distinguished by their rapid absorption. However, they are washed out as easily. Among them are the names that can be used not only as independent means, but also added to a variety of construction / plaster solutions. Then their protective effect increases several times. When diluting dry formulations, the dosages specified in the instructions should also be followed very precisely. Otherwise, you can weaken or completely neutralize their effectiveness.

    Organic remedies (or based onorganic solvents) are popular because of their absolute strength, efficiency. These antiseptics, impregnation can be applied not only on concrete surfaces, but also on brick, tile. They are quite toxic, so the use of personal protective equipment when working with them is mandatory. Organic impregnation does not destroy the metal armature, they are able to cope with any mold / fungal colonies in just 2 applications. And then a few years will protect the surface "entrusted to them". They can be successfully applied even where the infection is sufficiently strong and extensive. Organic means will not only destroy the colony, but will also become a reliable barrier to its re-emergence.

    Any oil antiseptic for concrete against moldfor the house should be used exclusively in non-residential premises. The reason is their increased toxicity, flammability, strong, unpleasant odor. Such funds do not react to water, that is, it is impossible to wash them. Surfaces treated with oil antiseptics will have a dark brown color, which is also not possible to paint over. Naturally, such surfaces also cannot be finished. Therefore, it is better to use oil formulations in basement, technical premises, not intended for permanent stay of people in them. Thorough airing for about a week after their use is mandatory.

    How to handle already contaminated concrete

    Of course, the appearance of fungus is easier to preventrather than fight him then. But if the moment is missed, the colony is formed, for the victory over it one measure will not be enough. It will be necessary to conduct a consistent, systematic struggle according to the following algorithm:

  • determine the causes of the colony;
  • remove completely finishing layers to the concrete itself;
  • the method of scraping completely remove the entire colony of the fungus;
  • dry the surface, apply antiseptic composition;
  • once again perform disinfection measures;
  • apply a water repellent with the addition of biocides in the primer, plaster solutions;
  • to carry out priming, plastering the surface directly on top of the antiseptic.

  • If possible, remove the fungus-infected surface.

    When the mold is scraped,It should be constantly applied to the surface of water, moisten it, because it may remain a certain amount of fungal spores. Water will prevent them from scattering. The selected antiseptic should be applied not only to the infected areas, but completely to all surfaces, even “healthy” ones. This will deprive the colony of the slightest chance to revive the existence after some time. Apply an antiseptic composition should be using a roller, sprayer, large brush. On those surfaces where there was a fungus, the composition in a day should be applied again, with the second layer. The same applies to areas with old, overgrown colonies.

    Preventing the appearance of new colonies

    Naturally, any inhabitant of the apartment, housewants the mold to never appear again. But for this, you should also make some efforts to implement preventive measures. And they need to be carried out in regular mode, despite the fact that asepsis for concrete is quite effective.

    Advice! Depending on the surface, brand of concrete,conditions of the room, you need to select the frequency of repetition of treatments. In living rooms, rooms that are heated, the composition is enough to apply only 1 time. If the room is not heated, the tool is applied every 15-18 years. Facades of buildings are processed every 8 years. Under any skin, an antiseptic is applied every 30 years.

    To prevent the formation of mold on concrete pavements, it is possible to use water-repellent impregnations against humidity as a source of fungus.

    Treat these recommendations should be quite seriously, strictly follow.

    Advice! Antiseptic need not only be used asimpregnating agent. Be sure to add it to the plaster, cement, tile adhesive, concrete itself. This will increase safety, reduce the likelihood of fungal, mold formations.

    In addition to direct processing, it is necessary to avoid creating such conditions in which the mold and fungus will develop rapidly, that is, it is not necessary to favor their formation or spread.

    Attention! Humidity in the room should not exceed 60%. It is necessary to provide rooms, other rooms with good ventilation equipment, to maintain it in working condition. If this is not possible, rooms and other rooms should be aired more often.
