In what cases you can"t do without concrete contact
One type of building material used in surface finishing is concrete contact. It is sometimes mistaken for a regular primer, however this is not totally accurate. A "family" of substances known as primers works to increase adhesion.
For processing especially dense smooth bases like concrete walls, ceilings, and floors, a composition known as concrete contact is used. Because each composition has unique properties and functions, we consider it in light of its intended use when deciding whether concrete contact or primer is preferable for reinforced concrete foundations.
Any concrete contact serves the dual purpose of leveling the walls and smoothing out any imperfections while also priming the surface for the application of finishing materials. For instance, even with the use of an incredible adhesive, it is challenging to affix tiles to the wall. On the other hand, the mission is made possible by the use of concrete contact, and its impact is greatly prolonged.
What general properties does concrete contact have
To put it briefly, concrete contact serves to establish the necessary conditions for the glue-free adhesion of foreign materials without the need for complicated adhesives. This kind of soil "sticks" to any surface due to its very composition. Multiple elements are combined to create a unique adhesive ability.
Note: Required materials include quartz sand, which improves the adhesive qualities, and special glue. Concrete contact may occasionally be enhanced, even with the addition of finely divided cement.
The uses for concrete contact primer are rather extensive:
- It perfectly bonds finishing and building materials with smooth, glossy surface textures.
- Improving the adhesion quality of plastered walls.
- Finishing surfaces without pre-cleaning previously applied materials. As an example: a high-rise building, the facade of which is laid out with tiles, is easier to treat with concrete contact than to clean everything down to the bare walls.
Kindly take note! Concrete contact is more complex than classic primer in terms of functionality. It is frequently used for other small tasks, such as protecting the surface for the winter.
The superior qualities of the primer betonokontakt elevate it to the status of an essential standalone material for finishing projects.
- Long service life. Some manufacturers give a guarantee of up to 80 years for the preservation of the properties of their products. Who will check the truth of such "red speeches", because, most likely, during the specified time, restoration work will be carried out in the room more than once.
- Drying speed. No more than two to three hours are needed for a correctly applied layer of betonokontakt to dry out and continue working with it.
- Moisture resistance. When drying, a film is formed on the surface of the betonokontakt. It is absolutely waterproof and serves as waterproofing, thereby protecting the main surface of the wall from adverse effects.
- Low consumption. There are certain standards according to which a specific amount of substance is required per unit area. But, due to a number of circumstances, it is not always possible to comply with them. Therefore, everything is individual here. Much depends on the surface being treated. Porous or rough texture will require a thicker layer of primer.
Concrete contact primers are typically classified according to the kind of surface they are applied to, such as metal, wooden walls, etc. Because the classification is conditional, this isn’t always taken into consideration in practice.
Concrete contact primer needs to be purchased from a specific brand for a specific type of work, as its composition varies.
Rating of the best brands of concrete contacts
Thus, you enter a store and become confused by the variety, not even knowing which deep penetration concrete contact primer is superior.
It is true that the manufacturer determines the quality of concrete contact, just like with any other product. The primer betonokontakt GOST 28196 is regarded as follows; it satisfies all standards and has grown to be a reference for numerous finishers.
Knauf
This well-known brand’s composition’s primary ingredients are combined with a particular water dispersion base that has fine-grained quartz sand in it. The Knauf concrete contact certificate attests to the increased reliability of fixing the mixture due to the production technology employed.
- Since Knauf concrete contact primer has the best characteristics among other compositions, even smooth surfaces are covered with it. Gypsum, lime, or its mixture with cement fits perfectly on it.
- Knauf concrete contact primer is well suited for concrete blocks, monolith and other surfaces that have poor adhesion under normal conditions.
- A distinctive feature of the mixture is the ability to dilute it before starting work with plain water in a ratio of 2 to 1.
- Once dry, the concrete contact will acquire a rough texture. Consequently, the next layer of finishing materials will hold quite reliably.
Take note! The drying time of Knauf concrete contact primer is one hour. The following layer can be applied after this point. Drying completely in about 4 hours. Especially when compared to extremely long construction times, this is practically lightning fast.
The best surfaces to use Knauf concrete contact primer on are those with a dense texture and low moisture absorption. It works just as well on ceilings as it does on walls and floors.
Betonokontakt overview For interior work, use Knauf 5 kg adhesive for concrete before plastering.
Concrete contact Knauf: approximately 350 grams of primer will be needed per square meter of area if the primer is applied in a single layer. However, the type and complexity of surface treatment determines the consumption rate, which is typically not standardized for soil of the concrete-contact type.
Prospectors
Primer "prospectors" are made with premium latex. The processed surface is strengthened by the addition of additional chemicals.
They fully get him ready for work and rescue him from the dust. Although the GOST for the primer concrete contact "Prospectors" is not required to be used, the product’s quality is fully compliant with the most recent version, as stated in the certificate for it.
In addition to the composition mentioned above, the primer primer prospectors are primarily used on surfaces such as aged tiles and monolithic concrete that do not absorb moisture. On the bulk floor, concrete contact is also frequently utilized. A comparatively low cost of 1800 rubles for 20 kg makes this possible.
Plaster is actively made using a similar primer, which is also applied prior to puttying. The substance strengthens the primary surface’s adhesive properties and dries extremely quickly. It has a faster drying time—no more than two hours—than its counterparts.
Kindly take note! It does not require any further setup in order to begin using it. Appropriate for DIY projects as well as professional use.
Betonokontakt Starateli: approximately 200 g of the composition are consumed per square meter of plaster, if they are used very sparingly. Betonokontakt: consumption per square meter on concrete: slightly higher, as multiple layers covering the base are required for improved adhesion.
Ceresit CT 19
The vertical surfaces are treated with this primer. It is typically used as a base layer prior to plastering or tile adhesion. High adhesion is provided by the composition’s quartz sand.
Although there isn’t a lot of work that the primer can be used in, it is still very popular. Such compositions are produced by a vast number of businesses due to high demand. Each of them has unique qualities and has the potential to produce an entirely unpredictable outcome.
Kindly take note! Betonokontakt "ST 19" is only meant to be used for home décor. Its wetting will cause it to lose its characteristics and come off the surface that it was applied to.
It is essential to carefully read the manufacturer’s recommendations and seek advice from qualified specialists regarding the nuances of working with such material before beginning any work.
At an average intensity of use, primer betonokontakt st 19 consumes roughly 0.52 kg/m3, reaching a maximum of 0.72 kg/m3. Once more, the trick is to get the hang of it and know how thick of a layer to apply the composition in order to have just enough, but not too much. Applying primer betonokontakt per square meter on a smooth concrete surface may result in a higher consumption rate.
Betonokontakt "Optimist"
The primary focus of the manufacturer is on producing a primer with the designation g109. The product is utilized for external, street finishing, according to this code.
It adheres strongly to a variety of surfaces, including ceramic tiles and drywall coated with oil paint. When dry, the primer betonokontakt g109 has a rough surface.
Kindly take note! Such a composition cannot be handled in temperatures lower than +5 degrees. A square meter requires 250–300 grams of primer betonokontakt on average. It takes four to six hours for it to completely dry. Depending on the kind of surface being treated, the amount of concrete contact used per square meter can also nearly double at the same time.
In contrast to certain other varieties, the Optimist concrete contact primer necessitates a thorough mixing process prior to application and works best on dry, clean, and level surfaces. Be cautious—certain manufacturers do not have a certified material that is comparable to GOST concrete contact primer G109.
G109 Concrete Contact: There are various versions of the packaging available. comes in weights of 3 kg, 5 kg, 6 kg, 12 kg, and 20 kg. incredibly helpful for small, solo tasks.
It’s evident from learning more about concrete contact primers that selecting the appropriate product can have a big impact on your building or remodeling project. Understanding the particular requirements of your project, such as the surfaces you’re working with and the environmental conditions they will encounter, is essential to making the best decision.
Think about the concrete contact primer’s adhesion qualities, drying time, and surface compatibility before choosing one. Superior primers usually have more adhesive power, so your later concrete layers or finishing coats will adhere to the substrate with greater stability. Quick drying times can be advantageous, particularly if you’re on a limited time frame.
Consider the application’s ease of use as well. Applying certain products is simpler than applying others, which can help you save time and effort. Seek for primers that require little preparation and have clear instructions. This can have a significant impact, particularly for smaller projects or do-it-yourselfers.
Lastly, remember to read user reviews and take the brand’s reputation into account. Experiences in the real world can offer insightful information about the functionality and dependability of the product. You can choose the concrete contact primer that best suits your needs and ensures a successful, long-lasting project by taking all these factors into consideration.
