Which filler to choose - the basic requirements for the
formulations If your interior provides for the walls or ceiling from gypsum board, then you will have to decide which shpatlevku to choose to make their surface as flat as possible. Today, manufacturers of building and finishing materials offer a wide range of fillers for leveling surfaces covered with gypsum boards( GKL).
When working with GCR, as a rule, a large number of joints, seams and cracks. They are the so-called "risk zones" of the design. They can multiply harmful microorganisms, from there can go cracked in the finish. The quality of gypsum board construction directly depends on the quality of seams. You can, of course, make every effort to fit the sheets of drywall as tightly as possible, however this will change little. Proceeding from this fact, you should choose a filler with excellent strength characteristics. At the same time, it should be flexible enough, because drywall is susceptible, albeit minimal, to movements with fluctuations in humidity and temperatures. Ecological composition and speed of its drying should also be a priority when choosing an equalizing mixture.
Be sure to ask the seller the values of those marking marks on the jar with putty that you do not know!
Specialists say that, taking into account these requirements, the best option is a plaster filler. It is based on natural material, calcareous fillers and additives that improve the characteristics of the mixture. In the sale of plaster putty can come ready, but most often it can be found on the shelves in powder form. To use it, just add a certain amount of water to the mixture.
What putty putty plasterboard - the main types of putty
In addition to gypsum compounds for leveling gypsum board surfaces, there is a huge number of very different putties. Each of them has its own purpose, so the question of which putty putty plasterboard is quite relevant with such a variety.
Depending on the purpose, it is customary to allocate several kinds of putty:
- Leveling. It is designed for the primary leveling of plasterboard surfaces. Allows you to mask the most significant defects.
- of the second layer. Such compositions allow to obtain an even and smooth surface of the skin of the structure. In addition, they are characterized by excellent adhesion to the first layer, which prevents it from peeling off.
- Specialized. Used to perform strictly defined tasks: puttying joints, sealing "breathing" cracks, etc.
When buying a leveling compound, you should pay attention to its main component. It may be already mentioned gypsum, cement, or those or other polymers. Gypsum putty is used quite widely, but is not recommended for use in rooms with a high degree of humidity. As for cement compounds, they are more resistant to moisture, but are prone to microcrack formation. In terms of their performance, polymer fillers are superior to these two types, but they are quite expensive. About this kind of leveling mixture for gypsum board should be told in more detail.
Which filler to choose for plasterboard - look at the polymer product
When deciding which filler to choose for gypsum board, you should analyze your needs and possibilities. So, polymer-based filler is suitable for leveling gypsum board surfaces in absolutely any premises, be it a niche in the bathroom or a ceiling in the kitchen, a romantic arch in the bedroom. However, the price of this product often stops consumers. That is why it is necessary to assess the scale of application of polymer putty.
In addition to the possibility of using in different rooms, the polymer leveling compounds differ in that they can serve for finishing finishing. Finishing putty helps to eliminate the smallest defects before the direct application of finishing finishing material, for example, by gluing wallpaper on gypsum board. That is why it is applied with the thinnest layer, not exceeding usually 1 mm. Even more thin layers are performed with the help of so-called "superfine" fillers. The thickness of their layer can be only 0.3 mm.
Thus, it is obvious that from all the variety of putty for plasterboard, due attention should be paid to polymer and gypsum compounds. Application of one or the other of them is determined by the level of humidity in the room.
