The definition of plaster is as follows – it is a finishing coating, which can be shaped after the curing of the construction mixture. It is used to apply to an infested surface (concrete, brick, and timber ) of an constructed structure and enables you to attain a rough leveling of these walls. The coating can attain several centimeters.
There are two large collections of plaster:
And in the event the first functions just as a foundation layer, which will then be applied concluding, and then the decorative is used as the last layer. The mixture is protected from most of negative environmental variables and allows you to create a beautiful texture on the surface. To summarizethe cosmetic mixes vary in their structure, their granularity is higher, and their plasticity is less.
Ordinary plaster has been divided into different forms, depending on the main component in the composition:
- The selection of plaster depends on the material where the walls are created. For instance, brick or concrete walls are completed with cement compositions. But, lime compositions will match walls made from silicate.
Previously, plaster blends based on clay were rather common. It’s better masterprofnastila.ru to decorate and insulate wooden buildings. But, its performance attributes aren’t satisfied. Since the purchase price of the product is reduced, plaster can be used for finishing agricultural buildings.
To achieve a rough leveling suitable compositions of its production. All these are cement-sand combinations, also compositions of lime and similar components. They are mixed with water. It’s these mixes are excellent for residential buildings placed in places where there’s a lot of noise (train stations, airfields, houses near stadiums, etc.).
The major difference between plaster and putty is the thickness of this layer applied. As stated by the technology, plaster is permitted to employ both a thin coating (a few mm) and a thick one (more than 1 cm). The application process itself can be divided into various stages:
- The method of spraying or sketching. Spattering is carried out by means of a mechanical tool. The process is fast and simple. Sketching is performed manually using a trowel or even master. The major intention is to smooth out any imperfections in the wall, creating a foundation coat of fixation on the face.
- After plastering or screeding, then it’s necessary to apply a smoothing layer. It could be a couple of layers. It will help build up the thickness of the layer on the walls and also to elongate the plane. And to increase adhesion, a primer is used. It’s the last. Often, rather than itputty is applied to the prepared surface. This will let you make an even more smooth arrangement. If you don’t do so, then the covering layer of plaster will probably be rough. Sometimes you need exactly this property. And just how long should plaster dry before puttying? All of it depends on the type of composition. This may be found out to the packaging out of the products.
- It turns out the putty on the finished plaster is a frequent thing. It is permitted to employ putty, moreover, it should even be done.
Since the leveling coating could be thick, the technologies of utilizing plaster entails the usage of beacons and net. Beacons – manuals, thanks to which a coating of any thickness is obtained evenly and without gaps across the length of the wallsocket. Beacons form a part on which plaster is elongated by means of a rule. And the mesh used for reinforcement between layers averts plaster from cracking, extending and coming off the surface.
According to the definition, even a putty is a paste-like or powdery substance used before the use of confronting substance in interior decoration. They allow you to receive a perfectly flat surface, smooth and of top quality, which may be painted or taped with binders.
