The definition of plaster is as follows – it’s a finishing coating, which is formed after the healing of the building mixture. It is utilized to apply to an infested surface (concrete, brick, wood) of an erected structure and enables you to attain a rough leveling of the walls. The coating can reach several centimeters.

There are two large collections of plaster:

  • Routine.
  • Decorative.

And if the first functions just as a foundation layer, which will then be applied concluding, and then the decorative is utilized as the final layer. The mix is protected from most of negative environmental variables and allows you to create a more beautiful texture in the surface. To summarize, the cosmetic mixes vary in their structure, their granularity is greater, and their plasticity is less.

Ordinary plaster has been divided into several types, depending upon the main element in the composition:

  • cement;
  • lime;
  • gypsum;
  • lime-cement;
  • lime-gypsum;
  • cement-gypsum.
  • The choice of plaster is dependent upon the material from which the walls have been made. By way of example, concrete or brick walls have been finished with cement compositions. But, lime compositions will suit walls made from silicate.

Previously, plaster mixes based on clay proved quite popular. It is a good idea to decorate and insulate wooden buildings. However, its performance attributes aren’t happy. Since the purchase price of the product is reduced, plaster can be used for completing agricultural buildings.

To attain a rough leveling appropriate compositions of its own production. All these are cement-sand mixtures, also compositions of lime and similar components. They’re mixed with water. It’s these combinations are perfect for residential buildings positioned in areas where there’s a whole lot of sound (train stations, airfields, houses near stadiums, etc.).

According to the technology, plaster is permitted to use both a thin layer (a few mm) and a thick 1 (greater than 1 cm). The application process itself may be divided into various phases:

  • The Way of spraying or sketching. Spattering is performed by way of a mechanical tool. The process is quick and simple. Sketching is performed manually with a trowel or master. The most important intention is to smooth out any imperfections in the wall, developing a base coat of fixation on the surface.
  • After plastering or screeding, it’s crucial to employ a smoothing coating. It may be a couple of layers. It will help build up the thickness of this layer on the wall and to elongate the airplane. And to raise adhesiona primer is applied. It’s the last. Many times, instead of it, putty is applied to the surface. This will let you create an even more smooth construction. If you do not do so, then the covering layer of plaster will be rough. Sometimes you need precisely this property. And just how long should plaster warm before puttying? Everything depends on the form of composition. This may be found out on the packaging out of the products.
  • It ends up the putty on the finished plaster is a common thing. It’s permitted to apply putty, additionally, it must even be done.

Since the leveling coating may be thick, so the technology of applying plaster involves the use of beacons and net. Beacons – guides, thanks to which a coating of any depth is accessed evenly and with no differences along the length of the wall. Beacons form a masterprofnastila.ru section where plaster is stretched by means of a rule. Along with the mesh utilized for reinforcement between layers prevents plaster from cracking, extending and coming from the surface.

According to the definition, even a putty is a paste-like or powdery material used before the use of confronting material in interior decoration. They allow you to have a perfectly flat surface, smooth and of top quality, that may be painted or recorded with binders.
