For repair work, when leveling the walls putty is used. Let's talk mainly about the finishing putty. All people know it. But we want to discuss carrying out plastering work in humid climates or rooms. This is a sore subject for the population of Adjara and, especially, for the inhabitants of the Black Sea coast. Not everyone knows that putty can be of different types and different purposes. In Georgia, everyone uses plaster-based putties (ex. Knauf at its best). For residents of Eastern Georgia, where the climate is drier, this is perfectly acceptable (except in specific wet rooms). But in the humid climatic conditions of Adjara, before using it, it is necessary to compare well all the pros and cons. Many people know that gypsum, like a sponge, absorbs moisture. First of all, for using gypsum-based putty it is necessary to create such conditions so as to further exclude the penetration of moisture into the room or house. This is very difficult and always costly to do. Craftsmen - contractors are obliged to provide this information to customers, and then they can choose any putty. We try to resort to alternative means of polymer. These funds are more expensive, but you pay once and for the long time.
Basically, we offer our customers to use acrylic based putties (sometimes based on cement). They have many positive properties that make them durable. They are highly compatible in terms of adhesion, with all sorts of bases. Here are some more important distinctive properties of acrylic putty:
* Environmental friendliness;
* Water vapor permeability;
* Resistant to temperature changes.
By the way, in use, it is much more convenient and elastic than gypsum plaster. It is also important for the craftsmen to know that unlike gypsum putty, it does not shrink when dry. This is important when filling plasterboard seams.
Since we touched on the topic of gypsum plasterboard seams, let's touch on this issue in more detail. It is impossible to pass by this topic, because a lot of mistakes are made when puttingtying plasterboard seams. The grossest and most unforgivable mistake is to use a starting putty when processing the seams (i. e. the first layer). This method is very popular among 90% of Georgian craftsmen. In fact, the starter putty is not suitable for seams, in fact, the starter putty is not suitable for seams. It is also popular in that it does not drawdown and does not have to putty many times. After using it, in almost all cases, the ceiling cracks during repairs and has to be corrected. Cracks also appear after repair. The reason for this may be, for example, subsidence of the housing foundation, since at this time the metal structure of the gypsum board is lowered in some places. There are many other reasons for cracking.
For seams, there are special putties designed specifically for this. They are more expensive, although they are needed only for seams and therefore, in the end, there is no big difference in price. In such cases, we use Knauf Uniflott. There are two types, standard (blue packaging) and moisture resistant (green packaging). The second is intended for damp rooms, such as bathrooms. Prior to use, it is necessary to prepare a little peculiar. Let's list some properties: Very flexible; Durable; Does not give a drawdown; Can be used without tape; Hard to crack.
