When priming walls for additional work, concrete contact is essential, particularly for smooth or low-absorption surfaces. The durability and quality of your project can be greatly impacted by proper preparation, regardless of whether you’re working with a painted wall or intending to install tiles.
It’s crucial to follow the right procedures when applying primer to a painted wall to guarantee that the subsequent layers adhere correctly. Although the procedure might appear simple, peeling and cracking can be avoided in the future by being aware of the particular requirements of various surfaces.
Is priming required for tile work? is a question that comes up frequently. Although skipping this step now could save time later on, there could be problems. Priming makes sure that, even on less absorbent surfaces, the tiles adhere firmly.
To ensure strong adhesion for subsequent layers, it is important to understand how concrete contact primer interacts with various wall surfaces. To achieve a dependable bond on painted walls, appropriate surface preparation and application techniques are essential. Furthermore, priming the surface with concrete contact before tiling can improve grip and avert problems later on, making it a crucial step for durable outcomes.

Betonokontakt: primer with superpowers
Navigating pages
The installation of building materials requires the use of adhesives with unique compounds that can support the weight of plasterboard, porcelain tiles, and tiles.
Simultaneously, the strength of the fastener is contingent upon the characteristics of the work platform as well as the adhesive mixture’s capabilities.
Betonokontakt, also known as BK, is a unique kind of primer that promotes the adhesion of materials like metal, glass, and wood that are difficult to do so. This composition has no equivalents.
What is betonokontakt: purpose and features
Betonokontakt is a primer for acrylic adhesive that also contains quartz. This kind of primer is used to increase the base’s roughness, ensuring that the fastener will be stronger. It also has a higher resistance to moisture.
Two varieties of BK exist:
- under putty;
- for plastering.
This composition stands out due to its versatility, which offers a multitude of applications for working with materials such as concrete, brickwork, plasterboard, porcelain stoneware, tiles, painted surfaces, wood, metal, and glass.
Application area of concrete contact
The addition of concrete contact to the toolkit for performing maintenance has made the jobs of finishers and builders a great deal easier. This composition is typically used as an introduction to
- walls made of concrete, brick or cinder block to increase the adhesion capabilities with the finishing material;
- drywall to reduce porosity;
- gluing elements with a smooth surface to any materials, incl.. glossy;
- ceiling before whitewashing;
- preservation of plastered areas for the winter.
Conditions for processing walls with concrete contact
A number of requirements need to be fulfilled in order to use this primer mixture effectively:
- Work is carried out only in conditions of positive temperature.
- High air humidity has a negative effect on the properties of concrete contact, therefore it should not exceed 70%.
- After applying the solution, the surface should dry for at least 12 hours.
- The surface on which the primer is applied must be pre-prepared. It is important to minimize the amount of dust, for this purpose washing with detergents is allowed. Irregularities are leveled.
How to apply concrete contact to walls
Applying the solution to the walls is done with a roller, spatula, or wide brush. It is advised to apply the base in two layers and then let it dry completely.
Use on walls beneath tiles
It is appropriate to use concrete contact under tiles when the surface has very little adhesion and hygroscopicity.
Expert finishers are dubious about the application of BK beneath tiles and only use it in special circumstances when installing on troublesome non-absorbent surfaces, like drywall, if the walls were leveled using it. Conventional primers are often utilized when tiling interior spaces.
On painted walls
It’s a widely held belief that BK works best for priming oil-painted walls, which are frequently impossible to remove. Its composition and properties are misunderstood, leading to this incorrect opinion. A minimum absorbency of the surface is necessary for the fixation of the thin film formed by the solution. To put it simply, concrete contact can adhere to oil paint; however, experts are unsure about its ability to hold tiles covered in an adhesive mixture.
First
In order to improve adhesion, BK is used to prime concrete, brick, or cinder block walls before applying oil paint or under plaster. It makes sense to use it in this situation.
When can further work be carried out
The solution dries fairly quickly—about five hours, and for certain brands, even faster—from three hours. However, seasoned artisans give their work extra time to dry, applying the solution in the evening and letting it sit all night.
A special primer coating known as "narrow specialization" is called Betonokontakt. Because it is more expensive than other primers, you should carefully read the packaging instructions and speak with more experienced craftsmen about its application in a given situation before making a purchase. This prudence will enable you to avoid overspending and save money on future repair requirements.
Wall Surface | Concrete Contact Application Tips |
Painted Wall | Ensure the paint is not peeling or flaking. Clean the surface thoroughly before applying concrete contact. This helps the primer bond well with the wall. |
Surface for Tiling | It"s essential to apply concrete contact under tiles, especially on smooth surfaces. It improves adhesion, making the tiles stick better and last longer. |
It is imperative to prime wall surfaces with concrete contact before applying any new coatings. As a result, problems like peeling or uneven application are avoided and a strong bond is formed between the old surface and the new finish, guaranteeing durability.
To ensure proper primer adhesion, the painted wall must be cleaned and roughened before applying concrete contact. By taking this step, you can be sure the new coating will look better and last longer.
Applying concrete contact is also a wise choice if you intend to install tiles. It improves the adhesive’s hold, ensuring that your tiles stay in place even in damp spaces like kitchens and bathrooms.
All things considered, applying concrete contact as a primer is an easy yet powerful method to raise the caliber and durability of your wall coatings. Whether you’re applying a wall covering, painting, or tiling, this step will help you get the best results.
