The definition of plaster is as follows – it is a finishing coating, which is shaped after the healing of the construction mixture. It’s utilized to apply to an ominous surface (concrete, brick, wood) of an constructed structure and enables you to achieve a rough leveling of the walls. The layer can reach several centimeters.

There are two big groups of plaster:

  • Regular.

And if the first functions just as a foundation layer, which will then be applied finishing, then the decorative is used as the last layer. The mixture is protected from all negative environmental factors and allows you to make a beautiful texture on the surface. To summarize, the cosmetic mixes differ in their structure, their granularity is greater, and their plasticity is significantly less.

Ordinary plaster has been divided into different types, depending upon the main element in the essay:

  • cement;
  • lime;
  • gypsum;
  • lime-cement;
  • lime-gypsum;
  • cement-gypsum.
  • The selection of plaster is dependent upon the substance where the walls are all made. By way of example, concrete or brick walls have been finished with cement compositions. But, lime compositions will match walls made of silicate.

Formerly, plaster blends based on clay were quite popular. It’s great to decorate and insulate wooden buildings. However, its performance attributes are not satisfied. Since the purchase price of the product is low, plaster can be used for completing agricultural structures.

To attain a rough leveling suitable compositions of its own production. These are cement-sand mixtures, and compositions of lime and similar components. They are blended with water. It is these combinations are great for residential buildings positioned in areas where there’s a good deal of noise (train stations, airfields, houses near stadiums, etc.).

As stated by the technology, plaster is permitted to apply both a thin layer (a few mm) and a thick one (greater than 1 cm). The application process itself may be divided into several stages:

  • The method of spraying or sketching. Spattering is carried out by means of a mechanical tool. The process is quick and simple. Sketching is performed manually with a trowel or master. The chief goal is to smooth out any imperfections from the wall, creating a foundation coating of fixation on the surface.
  • After plastering or screeding, it’s necessary to apply a smoothing layer. It could be one or more layers. It will help build up the depth of the coating on the wall and also to stretch the plane. And to raise adhesiona primer is used.
  • The covering coating. It is the last. Many times, rather than this putty is applied to the prepared surface. This will allow you to make an even and smooth construction. If you do not do so, then the covering layer of plaster will probably be demanding. There are times that you need exactly this property. And just how long should plaster dry before puttying? It all depends on the kind of composition. This can be discovered masterprofnastila.ru on the packaging from the products.
  • It ends up that the putty on the final plaster is a frequent thing. It is allowed to apply putty, additionally, it must even be carried out.

Since the leveling coating could be thick, the technology of utilizing plaster involves the usage of beacons and net. Beacons – guides, thanks to which a coating of any depth is accessed evenly and without gaps across the length of the wall. Beacons form a section where plaster is elongated by means of a rule. Along with the mesh utilized for reinforcement between layers averts plaster from cracking, crumbling and coming from the surface.

According to the definition, even a putty is a paste-like or powdery substance used prior to the application of facing material in interior decoration. They permit you to get a perfectly horizontal surface, smooth and of top quality, which may be painted or recorded with binders.
