Deep penetration primer for concrete: types and technical characteristics

Today, a wide variety of materials are used for indoor finishing work, and a deep penetration primer occupies a special place in this list. Thanks to the use of this composition, the repair process can be carried out at a fairly high quality level.

Today the primer is available in several forms.suitable for different types of work. But first you need to familiarize yourself with the features of this material.

Before you get acquainted with the main types of deep penetration primers, you need to understand what this material is and how it differs from other formulations.

This option is a kind of impregnation for a concrete surface. The primer can penetrate to a depth of 5 to 10 mm, depending on the type used.

Thanks to the use of this composition, it is possible to ensure maximum adhesion of the concrete and the finishing material. The penetrating primer is characterized by a high degree of moisture resistance and, moreover, has vapor-permeable properties.

In addition, it has high antiseptic properties that prevent the development of fungus and mold on the concrete surface.

Another feature of the penetrating primer is that it can reduce the consumption of those finishing materials that will be used in the future.

The use of the composition has a positive effect on air exchange in the room. In this case, the primer performs an insulating function inside the material.

After treatment with a penetrating compound, the surface becomes more resistant to various external influences. For example, this concerns the use of chemicals, which often lead to abrasion.

As noted above, the primer is used in the preparation of the walls. The composition is used if there is a risk that the finishing material is weakly fixed on the concrete surface.

Often, the composition is used in the absence of insulation of the monolith. On a base with a large number of pores, finishing materials are not fixed in the best way. That is why experts recommend using a deep penetration primer that "seals" all channels. The composition prevents the rapid absorption of various substances, which allows you to securely fix the finish.

Deep penetration primer is used for both interior and facade work. It protects concrete surfaces well from the influence of aggressive substances present in the atmosphere.

The construction market is rich in various types of deep penetration primers. To understand which of the options is best used for preparing a concrete surface, it is necessary to familiarize yourself with the properties of each individual composition.

The first and one of the most common types is the universal primer. Most often, the composition is used for internal work. Often, the versatile penetrating options are used for exterior facing renovation processes.

As for the cost of universal options, it is relatively low.In addition, the consumption of the primer during operation is low, which is one of the significant advantages. It is recommended to store universal options at temperatures from 5 to 35 degrees.

After treatment with a penetrating primer, the concrete surface must be left for 4-5 hours so that it is completely dry.

According to the manufacturers themselves, universal formulations belong to environmentally friendly groups of construction products. After processing, the surface will be well hardened and prepared for further manipulations. Often, a universal primer is used on a heated screed.

The next type is acrylic compounds. This option can be used to process any substrate, from wood to concrete. Many experts consider acrylic primer to be a universal type. The main feature of the composition is deep penetration into the base, which greatly simplifies the entire repair process in the future.

Often, manufacturers supplement the base of the primer with various additives, which increases its performance. Most often, the composition is combined with antiseptic components, so that the impregnation can be used to prepare surfaces in the bathroom.

Antifungal compounds are a separate type. This penetrating primer is suitable for a wide range of surfaces, including concrete. A distinctive feature of this species is the presence of fungicides in the base - components that can quickly destroy fungal spores. In addition, the impregnation prevents the development of harmful microflora in the room.

Antifungal primers can have a different basis, which is their main advantage. For the preparation of concrete surfaces, different types of compositions are used. It should be noted that the use of such impregnations is recommended for the treatment of those surfaces that have already been affected by mold.

Please also note that antifungal compounds are used exclusively to prepare the base for wallpaper. In addition, the impregnation has a rather pungent odor.

Another type is an antiseptic penetrating primer. Unlike the previous version, these compositions are used to prevent the development of harmful microflora. The primer is used to treat unaffected surfaces.

Most often, antiseptic compounds are used to prepare the walls and floors in the toilet and bathroom. A primer is applied before laying the floor material. At the heart of high-quality antiseptic impregnation, fungicides are always present. The advantage of primers is that they perform a strengthening function when working with loose substrates.

To eliminate imperfections on the surface, deep penetration latex impregnations are used. They are based on water and polymers, which provide decent technical properties for this type. These compounds are indispensable for processing metal, concrete and wood. Often this type of primer is combined with alkyd options.

The versatility of the compositions lies in the fact that they can be used for indoor and outdoor work. Latex primer strengthens well the bases, which strongly absorb various substances.

Facade impregnations are a separate type. Silicone and silicate compounds are ideal for outdoor use. With these options, cracks can be treated prior to filling.

When choosing a high-quality impregnation for a concrete surface, you should pay attention to several important points.

• Kind of work. If you intend to use an outdoor primer, it is best to choose acrylic or silicate compounds that are highly resistant to low temperatures.Latex or acrylic impregnations are the ideal choice for interior wall treatments.
• Material. For concrete surfaces, it is recommended to use alkyd or acrylic compounds, which will reliably strengthen the base and qualitatively prepare it for further manipulations.

• Finishing. Decide in advance what material you will use after surface preparation. For wallpaper, plaster or paint, different types of impregnations are used.

Another significant criterion is the drying time. If the primer is used for interior work, then it is best to use formulations that require 2-3 hours. This is due to the fact that the primer is applied in several layers, and prolonged drying significantly slows down the repair process.

You should also pay attention to the manufacturer and the cost of the penetrating composition. It is best to choose a product from a well-known brand that has managed to recommend itself well.

When working with deep penetration impregnation for concrete, there are several important rules to keep in mind. Before applying the composition, it is necessary to carefully prepare the base. It is necessary to clean the surface of dirt, fill cracks, and remove stains with a special solution. The concrete base must be clean and dry.

Next, you need to prepare the building mixture, focusing on the instructions from the manufacturer. Most often, the composition is kneaded in a 1: 1 ratio (primer and water). To apply the finished mixture, use a brush or roller. The spray gun will help speed up the surface preparation process.

Please note that it is recommended to wear rubber gloves before starting work. This will protect the skin from ingestion of the composition. After that, the penetrating impregnation is applied evenly over the entire surface. If the base is quickly absorbent, you will need 2 coats.

As for the consumption of the penetrating primer, it all depends on the surface itself. Average values ​​are 80-120 g per 1 m². Experts recommend leaving the surface for 24 hours so that it is completely ready for further manipulations.
