The definition of plaster is as follows – it’s a finishing coating, which can be formed after the healing of the building mixture. It’s utilized to apply to a infested surface (concrete, brick, and wood) of an constructed structure and permits you to reach a rough leveling of the walls. The layer can attain several centimeters.
There are two big collections of plaster:
And in the event the first serves only as a foundation layer, which is then going to be applied concluding, then the decorative is utilized as the final layer. The mix is protected from most of negative environmental factors and lets you make a beautiful texture on the surface. To summarize, the cosmetic mixes differ in their arrangement, their granularity is greater, and their plasticity is less.
Regular plaster has been divided into several forms, depending on the main component in the composition:
Formerly, plaster mixes based on clay were quite common. It is better to decorate and decorate wooden buildings. However, its performance characteristics are not satisfied. Since the purchase price of the product is low, plaster is used for completing agricultural buildings.
To accomplish a rough leveling appropriate compositions of its own production. All these are cement-sand mixtures, also compositions of lime and similar elements. They are blended with water. To get a plaster coating to have thermal and soundproofing qualities, foam glass, sawdust, polystyrene foam could be inserted to it. It is these mixes are great for residential buildings placed in places where there’s a lot of sound (train stations, airfields, houses near stadiums, etc.).
As stated by the technologies, plaster is permitted to apply both a thin layer (a few mm) plus a thick 1 (more than 1 cm). The application process itself can be divided into various phases:
- The Way of massaging or spraying. Spattering is performed by means of a mechanical tool. The process is fast and simple. Sketching is performed manually with a trowel or master. The main aim is to smooth out any imperfections in the wall, creating a base coat of fixation on the surface.
- After plastering or screeding, then it’s crucial to apply a smoothing layer. It could be one or more layers. It will help to build up the thickness of the coating on the wall and also to stretch the airplane. Each tier of plaster should dry, only then can you proceed to more manipulation. And to raise adhesiona primer is used. It’s the last. Frequently, rather than this putty is applied to the surface. This will allow you to make an even more smooth structure. Sometimes you need precisely this property. And how long should plaster dry before puttying? It all depends on the kind of composition. This can be discovered to the packaging out of the products.
- It ends up the putty about the final plaster is a frequent thing. It is allowed to employ putty, moreover, it should even be carried out.
Since the leveling layer could be thick, then the technology of applying plaster includes the use of beacons and net. Beacons – guides, thanks to that a layer of any depth is accessed evenly and with no differences across the length of this wallsocket. Beacons form a part on which plaster is elongated by a rule. And the mesh employed masterprofnastila.ru for reinforcement involving layers averts plaster from cracking, extending and coming off the surface.
According to the definition, even a putty is really a paste-like or powdery material used prior to the use of confronting substance in interior decoration. They allow you to acquire a perfectly flat surface, smooth and of high quality, that can be painted or recorded with binders.
