Concrete contact characteristics and application. Primer concrete contact, its technical characteristics and use. A few words in conclusion

Quartz vinyl tiles are only indirectly related to vinyl flooring: the composition is dominated by quartz sand - up to 80%... Only 15-20% is accounted for by polyvinyl chloride and other synthetic additives. Thanks to this, the material is incredibly durable, practically does not wear off over time. At the same time, PVC film makes it possible to imitate the texture of wood, stone, marble or porcelain stoneware.

Quartz Vinyl Tile Structure

A typical quartz vinyl consists of 5 layers:

Base... Polyvinyl chloride base.
Reinforcing... Balance layer with added fiberglass. Prevents deformation.
Quartz vinyl... Selected quartz sand with PVC. Strength, additional sound insulation, durability.
Decorative... Special foil with a pattern or texture on the flooring.
Protective... Transparent polyurethane layer. Protects the surface from damage.

The structure of quartz vinyl tiles is similar to other types, however, due to the presence of a reinforcing layer and quartz sand in the composition of the product, it is much stronger and has improved performance characteristics.

Application of quartz vinyl

PVC coating with the addition of quartz is used in rooms with temperature drops from -30 to 60 ° C, with any traffic intensity and humidity level. Because of this, and considering the variety of designs, the use of quartz vinyl floor tiles is almost unlimited!

Advantages of Quartz Vinyl Floor Tiles

Wear resistance

Durability is the main quality inherent in quartz vinyl, but the coatings are also scratch-resistant, not afraid of women's heels, and withstand moderate physical damage, for example, falling objects.

Abrasion resistant

The multi-layer structure of quartz vinyl in combination with polyurethane on the front surface provides reliable protection against abrasion: in this component, quartz vinyl tiles are in no way inferior parquet board made of natural wood or laminate.

Moisture resistance

Like PVC laminate, quartz vinyl flooring does not allow moisture to pass through, the seams are sealed. Thanks to this, the base remains dry, delamination or deformation over time is excluded.

Durability

Regardless of the operating conditions, with proper installation and the choice of high-quality material, the service life is at least 25 years. At the same time, quartz vinyl tiles do not require special maintenance, and if necessary, fragmentary repairs are allowed.

Operational installation

The base base practically does not require preparation - it is enough to clean the surface of debris and level it. Laying on concrete, wood, old linoleum or on a tile. Depending on the models, quartz vinyl is glued or installed using locking systems.

Chic design

The face surface of the quartz vinyl floor tile imitates natural materials... At the same time, screen printing is used, the texture is clear, high quality.

Now there are many materials for repair or construction in general. It often happens that ordinary or tile mortar is not enough to obtain reliable adhesion. In other words, you need a mixture that will provide a reliable bond between the wall and the attached object.

It is for these purposes that concrete contact exists. They say about him that he can bind absolutely incompatible materials. For example, glue metal and tiles or glue an object to a perfectly smooth surface (glass), and so on.

Description and features

Concrete contact Is a variety ground mixtures. Main advantage: transformation of a smooth surface into a rough one. The main constituent is quartz sand.

Strong adhesives and acrylic admixtures are used as additives. Previously, for a reliable bond, all the ingredients were used separately, but now manufacturers have combined everything into one mixture called concrete contact. What are characteristics possesses concrete contact?

First, the material has a strong resistance to moisture. Builders have repeatedly sought to obtain a bunch that would be completely indifferent to water. The new kind this material allows you to provide reliable waterproofing.

For example, under the floor screed or in the sauna / bath room. When dry, concrete contact creates a kind of film that does not allow moisture to penetrate further.

Secondly, it has the ability to dry quickly, while being absolutely safe, and does not emit foreign odors. After a few hours, you can start the next type of work. And thirdly, of all existing primers, it is endowed with a long service life (up to about 80-90 years).

Types of concrete contact

The building materials market offers a wide range of soil mixes. Repairers identify the most popular and reliable ones.

* Knauff soil mix has wide application for interior finishing works. For example, you need to prepare a plaster base walls for application, in this case, it is the best fit concrete contact.

We can say that "Knauff" is used for concrete and cement surfaces. And not only that, practice has shown good results on such bases as polystyrene and various foam blocks. Such a primer is very easy to apply, does not require special knowledge and effort, an approximate consumption for square meter will be 250-350 g.

* Primer mix "Axton" is considered universal and suitable for unprepared surfaces. This material has the following components: marble chips, acrylic admixtures, quartz sand, various polymers. It tends to dry quickly, and you can work with the treated surface after 2-3 hours. The approximate consumption for a quadrometer is 300 g.

* Priming"Prospectors" are a variety concrete contact, where one of the important components is latex. Often used for processing interior walls, has a low health hazard. Among all other examples, it is endowed with the highest adhesion qualities.

It is widely used for old surfaces: panels, brickwork, monoblocks. In a word, we can say that this soil is suitable for areas that are not able to absorb moisture. "Prospector", apart from being quickly dried (in just two hours), is also little consumed (about 200 g per square meter).

* Ceresit soil mixture is intended exclusively for interior surfaces. It is also used in the most difficult places where a high adhesion coefficient is required.

The composition includes only harmless components: mineral additives, copolymers, special pigments and aqueous dispersion. After three hours after application, the next stage of work can be performed on the surface. Consumption given concrete contact will reach 500-750 g per square meter.

Application of concrete contact

The most important advantage of the soil mixture is to create adhesion on those surfaces where moisture literally rolls off. This does not mean that it is only used for internal processing. As outdoor work concrete contact is used before the application of decorative facade plasters.

What preceded the concrete contact? Previously, builders used a special bandage to strengthen the ligament. A mesh of fabric played its role, and was applied using PVA glue. This type of work was lengthy and time consuming. Therefore, the invented primer has literally become a lifesaver for builders.

Now about the most important thing: the primer can be applied to the surface of any structure. As for the concrete, it was difficult to get the work done so that the plaster would last for a long time.

Concrete contact has proven itself only from the best side, this building mixture lasts for a long time. It is not recommended to apply it if the air temperature is below +5 C. Layers of application can be from 3 to 6 mm. Everything will depend on the content of quartz-sand fractions in the soil mixture.

How to apply? The priming process does not require any special skills, effort or tools. First, the surface should be carefully prepared: remove the exfoliated parts, clean it of dust and dirt, treat it with ordinary soil.

It is important that the area is free of oil stains or grease deposits. They are removed mechanically. After the usual one is completely dry, you can start applying the main adhesive.

For work, you need an ordinary brush, roller or spatula. Buy concrete in any building market and apply in a thin / even layer with a wide brush. The exact consumption per square meter is shown on the package.

Leave to dry for the time indicated in the instructions. The minimum period is at least two hours. Usually they check with a spatula, if the coating is easily removed, then the soil has not yet dried out.

Of course, everything will depend on the temperature and humidity of the air. Usually such work is carried out at night, by the morning the surface is already ready for the next stage of installation.

Experts in the field of construction recommend that the next stage of work be carried out immediately, that is, not left for an indefinite time. Because the concrete contact can get dusty, in this case the adhesion will only deteriorate. The repairmen will unanimously say that they haven’t come up with a better binder yet!

Price and reviews

Because of concrete contact is little consumed, this allows you to save not only on time, but also the price... The cost will depend on the manufacturer and on the packaging. Usually, the soil mixture is placed in buckets or containers, and the price range will be from 250 to 2500 Russian rubles.

Unfortunately, I want to warn you that the building materials market offers many fakes. Therefore, at the time of purchase, it is advisable to check the quality certificate or purchase from a trusted manufacturer.

The very first indicator of quality material will be gentle pink color and a pleasant smell of the building mixture. If everything is done exactly according to the instructions, then the quality of the treated surface and durability of operation are ensured. This is confirmed by the grateful

To obtain reliable adhesion of finishing materials to the surface during repair, various processing preparations are used. A good choice would be to use a concrete-contact primer.

It is important to select the constituents of the material so that there is no rejection of the incoming components from the base. Concrete contact contains polymer glue, which ensures its strong adhesion to the base. The result is a rough coating that can hold any decorative trim.

When preparing surfaces for further finishing, concrete contact is used due to its adhesive properties... Penetrating into the base material, it forms a rough layer that can be easily covered finishing materials... Another of its advantages is to absorb moisture that forms on concrete structures.

Unlike a conventional primer, the use of concrete contact allows you to save yourself from such work as cleaning walls and ceilings from old paint or whitewash. It can be applied directly to the paint, in any case, the adhesion of the base occurs. It is a primer and also serves as a waterproofing layer. It can be applied under tiles in bathrooms, kitchens and saunas.

Certain types of this product are used for outdoor finishing works, it is frost-resistant. For outdoor work, soil is used containing expanded clay or marble chips, as well as coarse quartz sand. This compound will hold up well facade plaster on concrete walls. If it is covered from the outside with concrete contact, it will be reliably protected from atmospheric influences.

Concrete contact happens various applications, depending on the input components, the size of the silica sand particles. Concrete contact, which includes coarse sand, is more often used for processing porous substrates.

Composition and characteristics

The concrete contact primer has the following composition of components:

Portland cement or cement;
Quartz sand;
Acrylic polymer;
Technological additives that ensure its vapor permeability, hygroscopicity, protection from chemical and biological influences.

The concrete contact necessarily includes quartz sand with various grain sizes. For example, Ceresit soil contains a fine-grained mineral filler, it is used for processing smooth substrates.

Concrete contact has such specifications:

Environmentally friendly product. Does not emit bad smell, harmful fumes. Its use does not require additional means of protection for the body and respiratory organs;
Resistant to aggressive environments;
Forms a waterproofing layer;
It allows air to pass through, which excludes the formation of mold, mildew;
Drying time at 20 ° C and 70% humidity is 3 hours;
Manufacturers have set its service life - 80 years;
The recommended temperature for indoor work is from +5 to +30 ° C and humidity is 55-80%.

How long the concrete contact will dry depends on the temperature and humidity in the room. Under unsuitable conditions, additional heating can be used to speed up the process.

Consumption

Consumption of concrete contact primarily depends on the size of the sand particles, the state of the treated surface. If it is too porous and rough, more material will be required than for a smooth one.

Here is the consumption of concrete contact per 1 m 2 for various surfaces:

For painted walls, metal and glass surfaces, ceramic tiles, other smooth and slightly porous coatings, 150 g / m2 is required;
Medium-porous structures made of concrete slabs, finishing bricks will require 300-350 g / m 2;
For very rough substrates such as concrete, building bricks, the consumption rate is increased to 500 g or more per square meter.

To reduce costs, conventional deep penetration primers are used for highly porous substrates, which are much cheaper.

Instructions for use

Before starting work, you should prepare the foundation. The processing process includes the following steps:

Rinse the surface from dust or dirt;
Remove aggressive formations: fat, bitumen, glue and others;
Knock off poorly adherent plaster, remove peeling paint, remove peeling wallpaper.

Primer concrete contact requires application to a dust-free surface, this is the main condition for obtaining a solid prepared base for finishing. Water-washed structures must dry well before application.

If the walls were previously covered with chalk, they are washed with soapy water and dried. Lime whitewash is removed if it crumbles and flakes.

The composition of the concrete contact primer is selected depending on the quality and condition of the surfaces to be treated.

Usually, the concrete-contact primer is ready for use, you just need to mix the composition before working. Sometimes it is diluted with water as directed by the manufacturer. It is important to ensure that the mixture does not contain lumps.

The concrete contact is applied with a painting tool - brushes, rollers, you can use a spray gun. Uneven concrete or brick walls are covered with a wide brush. This ensures the penetration of the concrete contact into cracks and seams.

For smooth surfaces, it is best to use a roller. You should try to apply stripes without leaving gaps between them. If the first layer has gaps, you need to apply the next one in order to paint over well. The next layer is applied after the previous one has dried.

The primed coating dries up after 3-12 hours. This time is indicated on the package, but the room temperature and humidity must be taken into account. To make sure that the soil is dry, you can slightly scratch it with a knife or spatula. Do not continue work if the strength of the layer is not reached.

Manufacturers

A number of manufacturers of concrete-contact primers are known on the construction market. They produce mixtures of various cost and composition, which are divided according to purpose and field of application.

Knauf

The concrete contact primer of this manufacturer is characterized by a finely dispersed composition based on fine quartz sand. It is used to cover smooth surfaces before finishing with plaster, lime, gypsum, tile adhesives, other finishing and decorative materials... Forms a rough surface.

Concrete contact Prospectors

Contains latex, which increases the strength of the base after processing. It covers surfaces that do not absorb moisture well. These are monolithic concrete, dilapidated cracked tiles, and other surfaces made of dense materials.

This species dries quickly (2 hours). When working with it, productivity increases significantly construction works... It is characterized by an economical consumption of 200 g / m 2. Shaking the contents of the can is sufficient before use.

Ceresite

Has a water-dispersed component in the base, contains polymers and coloring pigments. Tightly coats smooth concrete surfaces before plastering. We get a vapor and moisture resistant coating.

This soil should not be diluted with water; it is undesirable to use a roller for processing. Applicable only for interior work. It is non-toxic.

Axton

It is a dry primer mix. High quality primer for construction and finishing works. Before use, it is enough to add the required amount of water and stir. The resulting mixture is ready to use.

Axton concrete contact is used for uncleaned rough surfaces. The mixture consumption is 300 g / m 2, dries up within 3 hours.

So, we have determined what concrete contact is used for. The use of a versatile and reliable primer greatly simplifies construction. This material provides high performance properties of structures, allows to produce varied finishes external and internal surfaces.

Modern soil Betonokontakt is a high-quality material that contributes to the creation of surfaces that are durable and fully prepared for the application of building materials.

Impregnation of walls, slabs, partitions and ceilings with concrete contact allows you to connect materials of different structures, as well as increase the strength and resistance to moisture of the treated surfaces during the process of diffusion changes.

A special dispersion primer of polymer type Betonokontakt contains quartz sand, which gives the material the following features:

high adhesion of bonded surfaces;
ease of application without the use of special tools;
drying speed;
increased degree of resistance to moisture;
minimum permeability to water vapor;
ease of preparation and use.

The composition of the soil Betonokontakt allows you to use it not only for internal work, but also outdoors.

Material features

the standard drying time of the soil is about three hours;
high rate of waterproofing - when dry, the acrylic type of adhesive primer forms a high-quality moisture-proof film. When using mortar for concrete screed, there is no need to carry out waterproofing measures;
durability - the guaranteed service life of the surface impregnated with concrete by contact is about 80 years;
the indicator of the standard consumption per square meter of the treated surface is from 0.2 to 0.4 kg. and may vary depending on different conditions.

Application area. Why is it needed?

Primer Concrete Contact perfectly combines with low-porosity surfaces, and also adheres well to oil paint, concrete tiles, finishing bricks, monolithic and ferruginous concrete, sand concrete and building bricks.

The direct purpose of the Betonokontakt primer is the need to increase the adhesion of surfaces that have a weak ability to absorb moisture. A material such as monolithic concrete poorly settles on itself almost any building mixture, which makes the use of Concrete Contact very expedient.

Until recently, a kind of construction bandage was used for this purpose, which consisted of gluing it to a concrete base using a PVC fabric mesh. After drying, a layer of plaster was applied to such a mesh (read about, and). Now this one is uncomfortable and Long procces replaced by the use of Concrete Contact.

In addition, the composition of the soil Betonokontakt allows you to use it not only for indoor work, but also outdoors. It is allowed to apply a primer on metal and even wooden surfaces.

Application instructions

The application of a deep penetration primer of the Concrete Contact category is simple and does not require the use of special tools:

thorough cleaning of the treated surface from exfoliated fragments, dirt and dust;
pretreatment of surfaces with a conventional primer is allowed, which removes dust and promotes bonding of the surface layer;
using a brush, roller or spatula, apply Concrete Contact to the prepared surface.

Primer Betonokontakt must be applied to the surface in a uniform thin layer. Further, the layer needs to be dried, after which further work can be carried out.

It should be borne in mind that the time interval between the application of the Concrete Contact and the subsequent surface finishing should be minimized.
