Impregnation for concrete. the advantages of the protective

Building

Concrete, despite all its strength and durability, is subject to the influence of aggressive environments, and gradually under their influence the process of its destruction and deformation occurs. Impregnations help to avoid this effect, the most famous of which is polyurethane impregnation for concrete.

All about dust removal of concrete

In fact, all impregnations are a complete independent protective layer, which does not require any additional protective coatings. The layer will not become an obstacle if it is necessary to cut reinforced concrete with diamond circles.

The chemical basis of all impregnations are special polymer compounds.

Impregnations are used for the following purposes:

Dust removal of concrete floors.
Giving extra strength to concrete construction.
Waterproofing, that is, preventing the penetration of water into the pores.
Preventing a floor covering with a small network of cracks, if, for example, diamond drilling of holes in concrete is required.

The concrete base is already dust-free and fully operational.

Types of impregnation

There are several types of impregnations, each of which has certain properties.

The following categories can be distinguished:

Polyurethane. This impregnation on concrete is the most popular among builders. This popularity is quite justified by the fact that its price is low, and the range of tasks performed is quite wide. Display it as a table.

Sealing	The structure allows to provide full water tightness.
Dedusting	Especially true for concrete floors.
Chemical resistance to external influences	The design is completely protected from getting into it all sorts of chemicals.
Strengthening function	Allows you to significantly increase the resistance of the floor to shock.
Depth	The additive penetrates deep into the protected surface. The depth of penetration reaches 2-3 mm. This allows you to raise the strength characteristics of concrete to the M600 indicator and even higher. The firming function realizes itself in a similar way.
Decorative	The decorative effect that a given substance is capable of imparting to any surface plays a certain positive role.

Note! This impregnation can be applied at temperatures from -30 degrees.

The next view is impregnation of deep penetration for concrete. Its main feature is the ability to penetrate deep into the building material up to 5 times deeper than polyurethane. For example, concrete floors with medium brand strength are impregnated to a depth of 5 mm.

This type is used if it is necessary to carry out the maximum possible impregnation of the surface.

This mainly concerns the following cases:

Institutions and facilities where floors have a large erasure effect. In such cases, the component should penetrate as deeply as possible. It also helps protect the surface from dust.

Schematic representation of the principle of deep penetration

Industrial products and floors with high strength have a low porous structure, and it is quite difficult for ordinary additives to penetrate deep into. Here deep penetrating impregnations are necessary.
If it is necessary to strengthen the weak tie as much as possible, it is necessary to penetrate as deeply as possible.
If there is an urgent need to apply impregnation on wet concrete, then the only possible option is deep penetrating.

Acrylic additive is used for surfaces that are not subjected to stress, and if they are, this load is negligible. An example would be utility rooms, or floors covered with linoleum on top.

Applying the acrylic component on a concrete surface

Impregnations have been applied in the road sector. The fact is that the permanent repair of roads is a time consuming process. In order to minimize repairs and significantly increase the strength of the surface layer of the roadway, it makes sense to apply impregnation for asphalt concrete.

This is what asphalt concrete looks like before and after processing.

Independent work

One of the advantages of impregnation is the fact that all work on their addition can be done independently.

The instruction divides the entire workflow into the following steps:

Preparatory work, which provide for the cleaning of all garbage.
The composition is poured on the floor and try to evenly distribute it over the entire surface with brushes. It is also possible to apply the composition with a padding roller.
The composition is left on the floor for 1 hour for the initial soaking to occur. Then add some water to the composition and redistribute it (lithium impregnations do not require re-distribution).
After 20 minutes, the excess mixture is cleaned with a doctor blade, and the floor is thoroughly washed with water.

Independent application of the composition to the surface of the frozen solution

Note! As can be seen from the above instructions, there is nothing difficult to add soaking with your own hands.

Conclusion

The use of impregnations is justified in all cases of construction work on concrete. The video in this article will only confirm this thesis, clearly demonstrating all the advantages of the impregnating composition and its positive impact.
