What is this
Smooth surface plastering has been a pain for finishers ever since plaster mortars were invented. Concrete’s introduction caused the headache to become a significant issue. We were able to resolve the issue by using notches and bandaging, or fastening reinforcing mesh to the wall.
Everything about this process is challenging: it required a great deal of physical strength, took longer than expected, and cost more money. The producers of primer provided the answer. A range of concrete contact primers has entered the construction industry, allowing for the omission of the reinforcing step. Their ability to adhere to any surface makes them unique. In addition, the pull-off force (0.4–0.5 MPa) is adequate to maintain the finish type that follows. In addition, the primer itself has good adhesion to tile adhesive or plaster because quartz sand is a component.
Purpose
Concrete contact primers are primarily used to strengthen plaster and tile adhesive adhesion to materials that have poor adhesion to solutions containing lime, cement, or gypsum. This:
- concrete and reinforced concrete;
- ceramics;
- metal;
- tree;
- glass.
Take note: Betonokontakt does not claim to have good adhesion to metal, glass, or wood on its manufacturer’s websites. In limited areas, an experimentally obtained positive result was obtained. Priming the entire wall is therefore unnecessary because the plaster may eventually fall off.
When smooth materials are primed with Betonokontakt and allowed to dry, they form a sturdy foundation that can be used to apply plaster or tile adhesive.
Composition and technical characteristics
The following elements are used to create a water-emulsion dispersion of the "Betonokontakt" primer group:
- acrylic copolymers – responsible for the degree of adhesion to the base (concrete, glass, brick, plasterboard, etc.).d.);
- water is a solvent;
- Portland cement – enhances the strength of the polymer film;
- fine-grained quartz sand – forms a rough surface, resulting in excellent adhesion of solutions based on cement (gypsum) or tile adhesive with the resulting primer film. Some manufacturers, along with sand, add marble baby;
- modifiers and plasticizers – are responsible for plasticity, vapor permeability, water resistance of the composition;
- Sickatins (drying accelerators) – activate the polymerization process, and, consequently, drying;
- antiseptics – do not allow the fungus and mold to breed;
- dyes of pink or blue – indicators of the quality of surface processing. A colorless primer appeared in the building materials market, which begins to blush as it dries.
The quantity and composition of additives vary amongst manufacturers. Thus, discussing general technical and operational characteristics is not necessary. This is the mean:
- The amount of solid substance is 40-57%;
- grain size of quartz sand-0.3-0.6 mm;
- Density – about 1.37 g/cm 3;
- acidity-8.0-9.0 pH (on a scale 0-14, the indicator above 7.0 means a neutral environment);
- penetration depth:
- concrete M 300 – ≥ 0.5 mm;
- brick – ≥ 1.0 mm;
- cement plaster – ≥ 1.5 mm.
- drying time – 1-12 hours;
- storage temperature – +5 o C and above (only frost-resistant compounds can withstand 5 freezing/thawing cycles);
- application temperature – +5-+35 o C;
- operating temperature – from -40 o C to +60 o C;
- color: white, pink, blue or colorless compositions (begin to turn red as they dry);
- consumption – from 200 g/m2 to 750 g/m2 (depending on the base and manufacturers).
Among the conclusions are that the primer does not penetrate deeply, has a neutral environment, and does not freeze when stored.
Who invented this primer
It was technologists from the German company Feidal who first came up with the idea to mix primer components in this way. Their new product is called "Betokontakt," which is pronounced similarly in Russian. Though some manufacturers continue to refer to their products as "Betokontakt" in German, a more easily pronounced alternative has gained traction: "Betonokontakt."
By renaming their product, some Russian businesses are protecting themselves against legal action for using the primer’s name and formula without permission. You can see terms like "Concrete-contact," "Ground-contact," "Bettokont," etc. on buckets containing primer.
The invention’s creators’ formula is continuously being refined by adding new ingredients and adjusting their ratios. Consequently, the impregnation either gains new properties or enhances existing ones.
Kinds
Concrete contact primers are not officially categorized according to type. However, a number of classification groups can be identified:
- by grain size of quartz sand;
- Areas of use;
- method of application;
- release form.
By grain size
Two materials make up the "Betongrunt" feature: quartz sand, which guarantees adhesion with tile adhesive or plaster mortar, and copolymers, which, during polymerization, firmly adhere to the base. The weight of the ceramics that are glued and plastered differs. Because of this, we require a distinct clutch force when using primer. Different sized sand particle is the solution. Takes Place:
- fine -grained – the size of the grains of sand 0.3 mm;
- coarse -grained – size 0.6 mm. Provides an increased adhesion level by increasing the area of contact with solutions or glue for tiles.
Application area
Primers for internal work, facades, and universal ones that are suitable for both indoor and outdoor use are available for purchase. The packaging indicates the appointment time.
The method of application
Most manufacturers advise against using sprayers because sand clogs the nozzle. However, the formulations for applying in a mechanical manner—a spray—are still available for purchase. Based on this, the following categories of primers are separated out:
- for manual application;
- mechanized;
- mixed – method of application at the discretion of the consumer.
By release form
The primer can be obtained as follows:
- dry mixes – diluted with water in the proportion indicated on the bucket;
- ready-to-use composition.
The same manufacturer may produce ready-to-use primer and dry mixes simultaneously.
Pros and cons
Primer from the concrete contact group has advantages and disadvantages just like any other building material.
- improves adhesion to complex surfaces: concrete, glass, metal, tiles;
- dries quickly;
- have a long service life;
- are resistant to aggressive environments of plaster solutions;
- have waterproofing properties;
- do not serve as a base for the growth of fungus and mold;
- vapor-permeable;
- tinted for visual control of the quality of application;
- can be used indoors and outdoors;
- have a wide range of operating temperatures – from -40 o C to +60 o C;
- moisture-resistant;
- environmentally friendly.
- high price;
- harsh storage conditions – at temperatures below +5 o C and above +70 o C they lose their properties;
- increased surface requirements compared to deep penetration primers;
- fear of high temperatures during operation – at +70 o C, polymer fillers become viscous.
Application area
Many buyers do not consider the purpose of Betonokontakt when selecting an adhesive primer. You’re able to comprehend them. After all, the primer’s versatility is discussed almost everywhere: it can be used on all known wall materials, including wood, as well as smooth surfaces like metal, glass, and ceramics. It can also be applied to paint for any type of finish, including putty, plaster, liquid wallpaper, textured painting, and decorative plaster. Screed and self-leveling floors are also advised.
Indeed, it is feasible. But is it really necessary? Ultimately, such an overview:
- firstly, it costs a lot and will significantly increase the cost of money for repairs or construction;
- secondly, it does not penetrate deeply, creating in some cases a lower level of adhesion to the surface than plaster or glue directly to the base (more on this below);
- thirdly, when processing some surfaces, the consumption increases so much, and with it the financial costs, that the point of processing is lost. At the same time, there are alternative options of no worse quality, and several times cheaper in cost;
- fourthly, it is useless, for example, under a screed.
The following application areas are extremely challenging to operate without "Beton-kontakt":
- when plastering concrete and reinforced concrete surfaces – panels in panel houses, floor slabs, while the primer-contact is also needed when leveling the ceiling;
- finishing with ceramic tiles on tiles – the latter can not be knocked down, but primed with "Betonkontakt". This is enough for good adhesion with tile adhesive. It will withstand not only ceramics, but also porcelain stoneware;
- performing plastering and paint work;
- leveling wooden surfaces with “wet” plaster, but only small areas: beams, protruding structures. For larger areas, other technologies are needed;
- applying plaster solutions to metal – perfectly replaces metal reinforcing mesh, but also in small areas;
- for plaster walls in the bathroom and kitchen. Here it has several functions at once: it serves as a cut-off insulation between gypsum and cement so that the “cement bacillus” does not develop, increases the level of adhesion of tile adhesive to the wall, creates a waterproofing film, preventing water from entering the plaster;
- decorating the facade with simultaneous insulation – decorative plaster is applied directly to the penoplex.
That’s it. In other situations, there may be a better option available from other primers, or applying adhesive primers from this group is typically not permitted.
Where not to use
Rarely, manufacturers will state outright that they do not advise applying primer to loose or uneven surfaces. To put it gently, that. The strengthening is the primer. As a result, more than 0.5–1.5 mm does not pierce the material deeply. In conclusion, the wall or ceiling will collapse with any type of plaster, let alone tiles. As such, this is a categorical prohibition rather than a recommendation. Similarly, when gypsum boards are finished with tiles, the weight of the tiles—whether porcelain or stone—will rip the cardboard away from the gypsum body. The cardboard shell’s adherence to the gypsum is not improved by the primer.
Additionally, it is absurd to prime whitewash using cement-bonded particle boards, aerated concrete, foam blocks, chalk, or lime.
For information, cellular concrete is treated with deep penetration soil first, and only then are two to three layers of concrete contact soil applied, if that’s really what you want and can afford.
Use caution when applying cement plaster over primer. As a result, according to the packaging, some producers of plaster DSP ("Vetonit" TT40) do not advise using the mixture on a strengthening primer. In these situations, a deep penetration primer is applied to the concrete surfaces first, followed by "Betonokontakt" and plastering.
Use is permissible in other circumstances, but it is not advised because there are less costly alternatives. As a result, many owners use "Betonokontakt" to prime the tiles. This technology is being actively promoted by manufacturers. However, another important consideration is overlooked: our material’s hero has a peeling force of only 0.4–0.5 MPa, whereas tile adhesive adheres to plaster treated with a deep penetration primer at 0.8–0.9 MPa.
It turns out that in order to save money, you are destroying the quality of work that you hand-finish. Here, it is preferable to purchase a deeper penetration primer along with a more costly glue, such as "Plitonit" or glue from the mid-range (based). The quality is guaranteed, but the cost is roughly the same as a pair of "Betonkontakt" + glue.
It is preferable to forgo this primer in favor of self-leveling flooring, experience has shown. While gypsum-based compounds do not spread the solution as the manufacturer intended, cement-based compounds have poorer adhesion. It needs to be stretched in various directions using a trowel or spatula. Consequently, peeling, cracks, and other flaws are noticed after a few years. The self-leveling floors themselves were a blatant sin committed by the builders. However, we soon discovered a pattern: "Gruntokontakt" combined with a self-leveling floor causes issues when in use.
Popular manufacturers
Concrete contact soils are manufactured by a large number of companies worldwide. Regarding the price, quality, and component composition, everyone has their own trade secrets. An average consumer finds it challenging to navigate among them. Thus, the general advice is as follows: "Betonokontakt" will be of good quality if you enjoy other kinds of primers from a particular manufacturer. If we narrow our focus to particular manufacturers, there are roughly a dozen well-known brands in Russia. They are not listed in any specific order by us.
"Knauf." Fine-grained primer Betokontakt for gypsum plaster is supplied to the construction industry by the well-known German company Knauf. It has a slightly thick consistency and is not totally practical for manual labor due to its viscous composition, which makes it difficult to apply with a roller. Use a 2 to 1 dilution ratio when using a spray bottle.
When processing dense, smooth, and low-moisture-absorbing substrates, it is utilized inside. dries for twelve hours. You cannot, therefore, believe stories in fairy tales about drying in one or four hours. Either misleading advertising or a lack of knowledge about technical features are to blame for this.
- increases the adhesion of the gypsum solution to the base;
- manual and mechanized application is allowed;
- high resistance to the alkaline environment of concrete and cement plasters;
- small consumption for 1 m 2;
- There is no smell;
- pleasant pink color;
- easily mixed before use – sand practically does not precipitate.
- limited area of application;
- afraid of a waterlogged solution;
- It dries for a relatively long time, in connection with which they usually primed in the evening to start work in the morning;
- High price – starts from 122 rubles./kg.
- The most extensive area of application-for external and internal work, can be applied to concrete, stone and ceramic tiles, porcelain tiles, lime and cement-license plaster, screed, drywall, chipboard, OSB, as well as on the surface with difficult to make glue;
- The highest level of adhesion – you can glue tiles on the tile.
- increased moisture resistance;
- dries quickly – about 3 hours;
- allows you to use the technology of cladding with tile tiles with tiles;
- withstands up to two weeks of freezing during storage – the "winter" option;
- has indicator tinting;
- affordable price – starts from 90 rubles./kg.
- very high consumption – reaches 750 g/m2;
- counterfeited on a massive scale – when purchasing you need to ask the seller for a “Certificate of Conformity”.
"FEIDAL." The creator of the concrete contact group’s initial primer composition established "Faidal Paints," a facility in Russia that manufactures a variety of concrete contact primers. For combined use, "Feidal Super Kontakt" is thought to be the best. Essential for restoring historic structures with numerous surfaces coated in oil paint or drying oil.
- improves the adhesion of subsequent coatings by 5 times;
- vapor permeable;
- without smell;
- can be used indoors and outdoors;
- prevents the formation of efflorescence;
- ecologically pure.
- high price – the cost of 1 kg starts from 118 rubles.;
- manual application only.
Axton. First The "Axton" concrete contact group consists of a dry blend of marble chips, quartz sand, and polymers. packaged in 1.3, 3, 6, and 12 kg buckets. used to process any type of wall material’s uncleaned surfaces.
- good adhesion to the base and the finish applied on top;
- easy to work with;
- virtually no requirements for the surface being treated (only greasy stains are removed);
- fast drying – 2 hours are enough;
- affordable price – starts from 48.5 rubles./kg.
- actual consumption is much higher than indicated on the packaging.
Superior quality and dependability of concrete contact group primers, not just from renowned brands and businesses with a century-long legacy. Utilizing cutting-edge technologies, numerous emerging producers create primers that meet or surpass GOST and European standards. Among them are:
- "Bergauf";
- "Optimist";
- "Bolars" and others.
"Begauf". With filling from Germany and Russian origins, the primer sold under the German name "Bergauf" was manufactured with equipment provided by M-TEC Mathis Technik GmbH. It is advised by the manufacturer to treat any prepared substrates prior to applying decorative plaster, ceramic tiles, or plaster. The fact that it dries in 50–60 minutes is an important feature.
"Positive." The company manufactures a variety of concrete soils with contact groups. You must choose the item with the g109 label. The primer’s primary purpose is for external work, as indicated by the code. It adheres extremely well to paint and ceramic tiles, among other materials found on the wall facade. Winterizes perfectly, but the primer needs to be applied at a positive temperature, +5oC and above. Among the benefits are low consumption and an inexpensive price that begins at 72.5 rubles per square meter.
It would be impossible to overlook businesses like:
- "Eskaro" – smells sharp, but is convenient to work with;
- “Prospectors” is a quick-drying composition with a coarse sand fraction;
- “Osnovit” – dries in 1-2 hours, but is used only for gypsum-based plasters inside a house or apartment;
- Olympus is one of the cheapest soils of the group, but with good quality.
The list does not include any small regional businesses, many of which are also of a respectable caliber. Help the customer decide what to buy.
1 m 2 consumption
It is not required to discuss the standards. The indicator is impacted by too many factors:
- the size of the particles of quartz sand – the smaller, the thinner the layer is applied to the processed surface;
- The type of surface – smooth does not absorb the solution, in contrast to highly porous;
- the composition of the components – in various manufacturers, the consumption on the same surface is different.
Be aware that in certain works, the amount of water absorbed by the basis is one factor that influences consumption. This is untrue, though, as the primer does not apply to deep penetration primers. For instance, moisture is actively absorbed by reinforced concrete, but the primer only enters the material up to a depth of 0.5 mm and only into slightly deeper open pores.
In order to better illustrate the aforementioned points, we will create two tables that display the amount of "Betonokontakt" used per square meter based on surface porosity and manufacturer composition formulation.
Table 1 shows the approximate "Betonokontakt" consumption for various surface types.
Porosity degree | Type of material | Consumption, kg/m2 |
---|---|---|
high | all types of cellular concrete: gas silicate blocks, foam concrete, etc.d. | 0.45-0.75 |
average | concrete, brick, cement plaster | 0.20-0.45 |
low | ceramics, metal, glass, paint | 0.15-0.25 |
Table 2 shows the approximate Betokontakt consumption from some of the biggest producers.
Manufacturer | Consumption kg/m2 |
---|---|
"Betonokontakt" "Knauf" | 0.35-0.50 |
"Betonokontakt" "Ceresit" st. 19 | 0.30-0.75 |
"Betonkontakt" "Axton" | 0.30-0.50 |
"Concrete Contact" "Prospectors" | 0.20-0.30 |
"Betonkontakt" "Faidal" | 0.20-0.50 |
To ascertain a more precise consumption, a test application is helpful (plasterers say: make a sample). The following order is followed when performing the operation:
- 1 m2 of surface is selected on the surface to be treated with primer, tape or masking tape;
- the primer is poured into the tray (if priming is done with a roller), in an amount sufficient to treat the marked area;
- the roller is placed in the tray. If the work is to be done with a brush, it is placed in the factory container;
- the primer is weighed together with the tool;
- the primer is applied to the square meter marked with tape;
- the tool together with the remaining concrete contact is weighed again.
The consumption of the primer under these circumstances will account for the variation in scale readings. The area to be treated multiplied by the consumption yields a result that should be used as a starting point for calculating the quantity of "Betonkontakt" needed for the task.
Use instructions
Standard sections comprise the application instructions:
- preparatory work, including preparing walls and mortar for application;
- materials and tools;
- application technology.
How to prepare
You must get the surface and the application solution ready before you begin.
Surface
Certain surfaces require different requirements to be met by manufacturers. This is dependent upon multiple factors:
- soil composition;
- surface type.
Let’s examine the most popular choices.
Apply paint. The following actions must be taken if oil paint has tightly eaten into the base:
- where possible, remove the paint mechanically or chemically. You can see how to do this here;
- degrease the surface;
- treat the paint with coarse sandpaper or a metal brush to roughen it;
- use a chisel, axe or special tools (bush hammer, trojan, toothed – what is it – here) to apply a network of notches;
- remove dust. To do this, you can wash or vacuum, but thoroughly both.
Brick and concrete. Here, the procedures are essentially the same as those for paint:
- all types of previous finishing, as well as bitumen that got onto the wall after waterproofing the floor, are removed, except for paint that is firmly stuck;
- repair work is carried out, during which chips are removed, cracks and microcracks are sealed using repair compounds and deep penetration primers. Let us remind you that Betonkontakt does not penetrate deeply. Therefore, it is useless for these purposes. Problem areas in masonry joints are sealed;
Note: contact group concrete primers are not used when using porous materials (like adhesive foam) as a binder in brickwork.
- notches are applied to the wall;
- the surface is degreased and then dust-free;
Crucial: the soil fears that moisture will seep in from below. Therefore, waterproofing is done using a deep penetration primer under "Betonokontakt" or it is not used at all if there is a risk of capillary suction of moisture from the back side of the treated surface.
Compound
Two things are important for users of water-based primer dispersions to think about:
- During storage, a precipitate of quartz particles is necessarily formed. Therefore, thorough stirring is required before application. Some manufacturers recommend doing this every 30-40 minutes, about which there is always a corresponding recommendation on the container;
- Sometimes it happens that the primer has thickened. It is not recommended to dilute with water, except in cases of machine application. At least, this possibility is not mentioned on the official websites of the manufacturers listed above. In practice, a thicker consistency was applied. If anyone has diluted with water, please share your experience in the comments.
For any building or remodeling project involving smooth, non-porous surfaces like concrete or tiles, Betonokontakt primer is an essential product. By acting as a link between these difficult surfaces and fresh coats of paint or plaster, it improves adhesion and produces more durable outcomes. Betonokontakt improves finish durability, inhibits peeling, and facilitates a simpler, more effective application process. This primer is especially helpful for professionals and do-it-yourselfers who want their projects to turn out beautifully and professionally.
What to apply
To use primer, utilize:
- brush;
- poplar;
- brush;
- roller;
- spray.
Simultaneously, the tool requirements differ greatly from those for painting or applying other kinds of primers. The peculiar makeup of the soil is the cause.
If you’ve worked with basic primers before, applying "Concrete Contact" shouldn’t be too tough. However, it was absent. Everyone can see for themselves after giving it a try. Here, there are numerous issues:
- dense, thick consistency, reminiscent of kefir, or even thicker. Difficult to pick up and apply evenly;
- quartz sand clogs the pile of instruments – you need to periodically clean it, or even change it;
- sand crystals should lie as evenly as possible over the entire surface, and not be collected in one place;
- When working with a roller, it is important not to rush. Otherwise, a large amount of splashes will occur.
The tools are therefore picked with greater care.
Scrub. made to process joints and corners where the surfaces are perpendicular. Pile:
- hard – soft wears out quickly;
- medium or short – long pile quickly collects sand.
While working, you must continuously scrape the accumulated sand back into the solution using a spatula or the edge of a bucket.
The brush and Maklovitsa. utilized for treating sizable regions. mixed or synthetic pile. Prolonged. moderately tough. It is also necessary to clean accumulated sand on a regular basis.
Roller. Work faster, but soil consumption increases by 5-10%. The length should fit into a bucket of soil. It is advisable to have a long handle so as not to work from a stepladder (a lot of splashes get on clothes, hands and face). You should immediately discard foam rubber – it quickly “woodens” from the accumulated sand. Pile 12-18 mm long made of faux fur (a short one takes little composition, a long one splashes a lot). It also clogs quickly, but it can be cleaned using the edge of a bucket or a spatula – whichever is more convenient for you. If it stops working, replace it with a new one.
Apply. increases the speed of applying primer even further, but frequent nozzle blowing is necessary.
How to apply
On a dry, ready base, a thin layer of primer is applied. Using a brush or brush is preferable for rough surfaces because it ensures that the composition enters all of the pores; a roller is better for smooth surfaces.
There will be situations where a second or even a third layer is necessary. They are all applied to the prior layer that has thoroughly dried. You must ascertain the drying time of the "Betonokontakt" brand you purchased in order to proceed with the task. This kind of data is consistently accessible on the bucket.
The primer’s color determines the processing quality; areas that are left unpainted or with light color are processed further prior to polymerization starting. It is best to wait until the soil dries completely before treating the damaged areas again if you can wait a little while.
Remembering that sand particles settle in sediment is important. Consequently, even if the manufacturer does not specifically mention it in their usage instructions, it is still a good idea to constantly stir the prepared solution (unlike in the case of the Knauf company, who maintain that sand never settles in their solutions).
When priming is done correctly, you can create a strong foundation for additional finishing.
Expert advice
There are a few subtleties that home craftsmen should be aware of when priming walls with concrete contact primers.
1. Applying deep penetration compounds first will help cut down on the need for costly primer by 30–40%. You can use just one layer of "Betonkontakt" in this situation by applying porous substrates two to three times.
2. You are unable to prime:
- wet surfaces – only dried to 2-3% humidity;
- frozen bases;
- areas with stains of grease and dust;
- at temperatures below +5 o C. This does not mean that the soil cannot be used outside in winter, if the manufacturer allows it. Here you need to see the difference between storage – the composition changes properties at low temperatures and operation – after polymerization the primer can withstand up to -40 o C;
- a composition that has expired or has been exposed to frost during storage or transportation (several companies allow their products to be left in the cold for a short time, just in case of transportation in winter, but in most cases only once).
3. The plaster application solution shouldn’t be more liquid than what the technology calls for. will eventually decrease in size.
4. As soon as the primer has dried, you should get to work again. The adhering dust makes the surface unsuitable for applying tile adhesives or plaster mortars after just two days. Reprocessing is necessary.
5. This point builds on the previous one: you must prime a surface so that it can be tiled or plastered in a matter of one to two days.
6. Watch out for imposters. Don’t be afraid to request a certificate of conformance from the seller.
7. Avoid using heat guns or strong ventilation to hasten the drying process as this will interfere with the polymerization process. Generally speaking, this is bad.
Betonokontakt primer is an essential component of contemporary building and remodeling projects. It is an essential product for guaranteeing the longevity and durability of different coatings because of its exceptional adhesion to dense, smooth surfaces like brick and concrete.
Applying Betonokontakt primer can greatly improve the performance of later plaster, paint, or tile adhesive coats. Because of the rough texture this primer leaves on the surface, the materials will adhere more firmly and consistently. As a result, there is less chance of peeling or cracking over time and the finish is more consistent and even.
The application of Betonokontakt is simple, but for optimal results, it’s crucial to adhere to the manufacturer’s instructions. To achieve the desired results, proper application techniques and surface preparation are essential. This primer is a useful addition to any construction toolkit because it is adaptable and appropriate for both indoor and outdoor use.
To sum up, Betonokontakt primer is a workable way to raise the performance and adhesion of finishing materials. Its advantages go beyond practical use; it also improves the long-term look and quality of your remodeling and building projects. Betonokontakt primer can assist both professional and do-it-yourself enthusiasts in producing a more long-lasting and visually appealing finish.
