Antiseptic for concrete: features of choice and application

20-08-2018

Building

Concrete is one of the most popular building materials, which is used in almost all stages of installation. However, it has a certain absorption and is able to retain moisture inside for a long time, which often leads to the appearance of fungus on it. Therefore, professional craftsmen strongly recommend the use of a special antiseptic for concrete from mold, which, in addition, can additionally serve as a primer.

Application features and varieties

Для начала необходимо сказать о том, что плесень или грибок, который появляется в результате повышенной влажности, представляют довольно серьезную опасность для человеческого здоровья, поскольку являются распространителями и возбудителями многих болезней (читайте также статью «Уплотнение бетона – теория и практика данного процесса»).

Also, these phenomena have a negative effect on the structure itself, since they destroy it. That is why the antiseptic for concrete walls are trying to use at all stages of the construction of the structure and even added to the solution.

Kinds

First of all, it is worth noting that there are materials that are used during installation and those that are used during infection.. However, they have completely different composition and concentration. Given this, and should be guided when choosing a specific product.

Some types of such compounds are designed for direct addition to the solution at the stage of its preparation.

There is also a separate antiseptic for concrete. It was specially developed for use with this material, which means that it contains substances that do not enter into an unnecessary chemical reaction with some particles, and is simply ideal even for other cement mixtures.. If the treatment is performed with a compound that is intended for wood or metal, then the desired effect will also be achieved, but its quality and absence of consequences is not guaranteed.
It is worth noting that most of these compounds are sold in combination with a primer. This allows one problem to solve several problems at once. Especially it should be remembered that the primer may have a number of special qualities that it receives during the development, because it will help to choose the composition that is ideally suited to a particular room.

Tip! Virtually every additional property of this material is sharply reflected in its value. Therefore, you should not purchase multi-functional products, as this will lead to high costs.

Primers very often contain antibacterial substances.

Treatment

To begin with, it is worth mentioning that the installation manual strongly recommends that all work be done using personal protective equipment.

The fact is that not only mold and fungus emit substances harmful to the body, but also compounds that neutralize them can also be poisonous.

After these treatments, the surface may get water repellent.

Before processing, reinforced concrete is cut with diamond circles or another procedure envisaged by the technical process. After the composition is applied to the surface, the design should not be subjected to various kinds of impacts.
The application of the composition is performed using a sprayer, pre-cleaning the area to be treated with a brush with metal bristles.

It should be noted that the number of layers of these compositions should not be less than two. At the same time, an interval of several hours is maintained between them. The fact is that the price of primers with antiseptic properties is not very high, so it is usually spent abundantly.

Tip! Some masters recommend applying primer on a concrete surface as long as it actively absorbs moisture. This is usually 3-4 layers, which is applied after 4 hours.

Recommendations for use

If the work is done by hand, then it is necessary to add a small amount of pigment or dye in the composition, so that it acquires color and is visible on the surface.

Quite often, when antiseptic processing used copper sulfate. However, it does not perform the function of increasing adhesion, but only fights infection.

Adding pigment to the composition will help to distinguish the treated surface from that on which the mixture was not used.

When producing diamond drilling holes in concrete, it is often used coolants with the addition of such substances. Such impregnations perfectly penetrate the deep structure of the material and even help in this process.
If after the primer paint or wallpaper will be used, then you need to withstand time until the composition is completely dry. Applying the same putty can be made on the wet surface of concrete.

For small amounts of work, you can use a brush or roller.

Conclusion

After reading the video in this article, you can get more information about what are liquid antiseptics and how they are used when working with concrete. Also on the basis of the article outlined above, it is necessary to conclude that these compositions play a rather serious role in modern construction, since they solve the problem of safety of future tenants (find out here that aerated concrete or foam block is better).
