If you are new to the field of repair, you need to know in advance about the problems that you will face in the course of independent work. One of such problems is the application of various finishing materials to the hard surfaces of ceilings and walls. Beginners often face the fact that after drying, the paint or plaster applied to the concrete falls off, and the most reliable adhesive is not able to keep the tile on the concrete surface. The key to solving problems of this kind is the concrete contact.
The main components of concretecontact are polymeric materials, cement, sand and special additives. Being a kind of primer for various finishing materials, it plays the role of a binding layer of these materials with a solid wall surface or, as experts say, its role is to increase the adhesion of these two layers.
So, if you want to have full confidence that after drying the plaster will not fall off the wall, or that during the drilling of the holes in the wall the piece of plaster does not fall off and the hole will have the ideal shape, you should in the repair processuse concrete contact.
How the concrete contact
works The rough concrete surface is almost perfectly smooth, none of the finishing materials can be fixed on it. If this surface is treated with concrete contact, it will become rough like sandpaper, which will provide virtually problem-free fixing of any finishing material - whether it is flexible stone or ordinary wallpaper. Therefore, this mixture is used on ceilings to prevent shedding, as well as on concrete slabs and walls, before they are applied on plaster, or paint, or before they are attached to the finishing tiles.
Purchase and application of
Concrete contact is sold in buckets or barrels. Its use depends on the brand and on the characteristics of the surface to which it is applied. Consumption is determined by the properties of the surface: the more it is prone to moisture absorption, the higher the consumption of concrete contact. Whatever brand of concrete contact you have bought, no additional action is required to prepare it for use: just open the lid and mix it.
Drying takes place 3-4 hours at room temperature and provided that the humidity is not excessive. Walling of finishing materials should be carried out immediately after the drying of the concrete contact layer, which avoids the accumulation of dust that degrades the adhesion properties of the applied layer.
Safety
Acrylic concrete contacts are characterized by ecological purity and safety, which allows them to be used both for external and internal works. Their application does not interfere with the penetration of air and allows the premises to "breathe" without adversely affecting the internal microclimate. For mixtures, resistance to mold, fungi and parasites is characteristic.
Storage procedure
Concrete contacts can be stored in closed form for up to one year, provided that the temperature in the storage place does not fall below zero. If the mixture freezes, it loses its properties and becomes unsuitable for use.
