The definition of plaster is as follows – it’s a finishing coating, which is shaped after the curing of the construction mixture. It is utilized to apply to an untreated surface (concrete, brick, and timber ) of an erected structure and enables you to attain a rough leveling of the walls. The layer can attain several centimeters.
There are two large collections of plaster:
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 last layer. The mixture is protected from all negative environmental factors and allows you to make a gorgeous texture on the surface. To summarize, the masterprofnastila.ru decorative mixes vary in their structure, their granularity is greater, and their plasticity is less.
Regular plaster is divided into different forms, depending on the Primary component in the composition:
Formerly, plaster blends based on clay were quite popular. It’s fantastic to decorate and insulate wooden buildings. But, its performance characteristics are not satisfied. Since the purchase price of this product is reduced, plaster can be used for finishing agricultural structures.
To accomplish a rough leveling suitable compositions of its own production. These are cement-sand combinations, also compositions of lime and similar components. They are blended with water. It is these mixes are best for residential buildings positioned in areas where there is a lot of noise (train stations, airfields, houses near stadiums, etc.).
The principal difference between plaster and putty is the thickness of the layer applied. As stated by the technologies, plaster is permitted to use both a thin layer (a few mm) plus a thick 1 (greater than 1 cm). The application process itself can be divided into various phases:
- The method of spraying or sketching. Spattering is carried out by way of a mechanical instrument. The process is quick and simple. Sketching is performed manually using a trowel or master. The chief aim is to smooth out any imperfections in the wall, developing a base coating of fixation on the surface.
- After plastering or screeding, then it is necessary to apply a smoothing coating. It may be one or more layers. It will help to build up the depth of this coating on the walls and also to elongate the airplane. Each layer of plaster has to dry, only then can you proceed to additional manipulation. And to raise adhesion, a primer is used. It’s the last. Often, rather than this , putty is applied to the prepared surface. This will let you create an even and smooth construction. Sometimes you need precisely this property. And how long should plaster warm before puttying? It all depends on the kind of composition. This can be found out on the packaging out of the products.
- It ends up the putty about the final plaster is a common thing. It’s allowed to apply putty, additionally, it must even be accomplished.
Since the leveling layer could be thick, the technologies of utilizing plaster requires the usage of beacons and mesh. Beacons – guides, thanks to that a coating of any thickness is obtained evenly and with no differences across the length of this wallsocket. Beacons form a part where plaster is elongated by means of a rule. Along with the mesh employed for reinforcement between layers averts plaster from cracking, extending and coming from the surface.
According to the definition, even a putty is a paste-like or powdery substance used before the application of confronting substance in interior decoration. They permit you to acquire a perfectly horizontal surface, smooth and of top quality, that may be painted or recorded with binders.
