What is it?
The composition of concrete contact includes polymers, fine-grained quartz sand and various additives. The correct proportion of the constituents in the production of the primer ensures an increase in the adhesion of the layers. In other words, it acts as a binding component between concrete and finishing material, providing a high degree of stability of paint, plaster or tiles.
Application of concrete contact
The primer of concrete contact is used as a base, preparing the surface for applying the following finishing layers. It significantly increases the adhesion force between the wall( ceiling) and the lining. The principle of the soil is explained by its rough structure, which can be observed in the photo.
After applying a concrete contact to the wall, it acquires a sandpaper structure, ensuring effective fastening of the lining material. In particular, the soil is required for the work on the plaster ceiling.
In the video, you can see in detail the technology of applying concrete contact, which even a novice can handle in the repair and construction business. It is important to consider, the composition of the primer does not provide for its storage at minus temperature and application to the frozen surface.
The use of concrete contact and its consumption per 1 m2 depends directly on the application surface. The porous structure of concrete or brick provides a ground consumption of 0.3 to 0.5 kg. When applied to monolithic concrete or finishing bricks, up to 0.4 kg of material is required. Reinforced concrete, ceramic tiles and painted surfaces will require up to 0.25 kg of acrylic base.
Technical characteristics of the concrete contact
Below are the characteristics of the priming of a concrete contact of different grades:
Advantages of the
The characteristics of a concrete contact determine its main advantages:
- can be used on concrete, reinforced concrete, gypsum board, pro-polished and painted surfaces, as well as on expanded polystyrene and tiles;
- availability of two types of fraction: 0.3 mm is used before puttying, 0.6 mm - before plastering;
- high level of vapor permeability and hydrophobicity;
- efficiency and ease of application;
- the presence of fungicidal additives eliminates the appearance of fungus and mold on the finishing surface;
- environmental friendliness and safety.
Disadvantages of
What are the drawbacks of concretecontact? To get a truthful answer to this question, it is logical to review the reviews on its application, functionality and practicality. Incorrect soil application technology and non-compliance with the requirements specified by the manufacturer will be the primary cause of poor repair. For example, the use of an acrylic base on a layer with peeling old paint will cause the lining to fall off soon. Therefore, it is important to apply concrete to strong and reliable surfaces.
