The definition of plaster is as follows – it is a finishing coating, which can be shaped after the curing of the building mixture. It is utilized to apply to an untreated surface (concrete, brick, and timber ) of an constructed structure and permits you to reach a rough leveling of these walls. The layer can attain several centimeters.

There are two large collections of plaster:

  • Regular.

And in the event the first functions only as a foundation layer, which will then be applied concluding, then the cosmetic is used as the final layer. The mixture is protected from all negative environmental variables and lets you create a gorgeous texture in the surface. But because we would like to understand what the distinction between a simple plaster and putty, we are not going to touch the cosmetic mixes. To summarizethe decorative mixes vary in their structure, their granularity is higher, and their plasticity is less.

Ordinary plaster can be divided into different forms, depending on the Primary element in the essay:

  • cement;
  • lime;
  • gypsum;
  • lime-cement;
  • lime-gypsum;
  • cement-gypsum.
  • The option of plaster is dependent upon the substance from which the walls have been made. For instance, concrete or brick walls have been completed with cement compositions. But, lime compositions will suit walls made from silicate.

Previously, plaster blends based on clay were quite popular. It is good to decorate and decorate wooden buildings. But, its performance attributes aren’t happy. Since the price of the product is reduced, plaster is used for finishing agricultural structures.

To accomplish a coarse leveling appropriate compositions of its own production. These are cement-sand mixtures, and compositions of lime and similar elements. They are blended with water. It is these mixes are ideal for residential buildings placed in places where there’s a whole lot of noise (train stations, airfields, homes near stadiums, etc.).

According to the technologies, plaster is permitted to use both a thin coating (a few mm) and a thick 1 (more than 1 cm). The application process itself may be divided into several phases:

  • The method of massaging or spraying. Spattering is performed by way of a mechanical tool. The process is fast and simple. Sketching is performed manually using a trowel or even master. The most important intent is to smooth out any imperfections from the wall, creating a base coating of fixation on the face.
  • After plastering or screeding, then it is necessary to employ a smoothing layer. It can be a couple of layers. It helps to build up the thickness of this layer on the walls and also to elongate the plane. masterprofnastila.ru And to raise adhesion, a primer is used. It is the last. Often, rather than this , putty is applied to the surface. This will let you create an even more smooth structure. Sometimes you need precisely this property. And just how long should plaster dry before puttying? All of it depends on the kind of composition. This may be discovered to the packaging from the products.
  • It turns out the putty about the final plaster is a frequent thing. It’s allowed to apply putty, moreover, it must even be accomplished.

Since the leveling coating could be thick, then the technologies of utilizing plaster involves the usage of beacons and mesh. Beacons – guides, thanks to which a coating of any depth is obtained evenly and with no gaps along the length of this wall. Beacons form a section where plaster is elongated by means of a rule. Along with the mesh used for reinforcement between layers averts plaster from cracking, crumbling and coming from the surface.

According to the definition, even a putty is really a paste-like or powdery material used prior to the application of confronting material in interior decoration. They permit you to find a perfectly flat surface, smooth and of top quality, which can be painted or recorded with binders.
