The definition of plaster is as follows – it’s a finishing coating, which can be shaped after the healing of the building mixture. It is used to apply to an ominous surface (concrete, brick, and wood) of an amalgamated structure and enables you to accomplish a rough leveling of these walls. The layer can attain several centimeters.
There are two large collections of plaster:
And if the first functions just as a foundation layer, which is then going to be applied finishing, then the cosmetic is utilized as the last layer. The mixture is protected from most of negative environmental variables and lets you make a beautiful texture in the surface. To summarizethe cosmetic mixes vary in their structure, their granularity is higher, and their plasticity is significantly less.
Regular plaster has been divided into several forms, depending on the main component in the composition:
- The option of plaster depends on the material from which the walls have been created. By way of instance, concrete or brick walls have been completed with concrete compositions. But lime compositions will match walls made of silicate.
Formerly, plaster mixes based on clay proved quite common. It’s better to decorate and insulate wooden buildings. However, its performance features aren’t happy. Since the price of the product is low, plaster is used for finishing agricultural buildings.
To reach a rough leveling suitable compositions of its own production. These are cement-sand mixtures, also compositions of lime and similar components. They’re mixed with water. To get a plaster layer to have thermal and soundproofing qualities, foam glass, sawdust, polystyrene foam may be inserted into it. It is these combinations are ideal for residential buildings positioned in masterprofnastila.ru areas where there is a whole lot of noise (train stations, airfields, homes near stadiums, etc.).
The major difference between plaster and putty is the thickness of this coating applied. According to the technologies, plaster is permitted to employ both a thin coating (a few mm) and a thick one (more than 1 cm). The application process itself may be divided into various phases:
- The method of drawing or spraying. Spattering is performed by means of a mechanical instrument. The process is fast and simple. Sketching is done manually with a trowel or master. The chief intention is to smooth out any imperfections in the wall, developing a base coat of fixation on the face.
- After plastering or screeding, then it’s necessary to apply a smoothing coating. It can be one or more layers. It will help build up the thickness of this layer on the wall and to stretch the airplane. Each layer of plaster must dry, only then can you proceed to further manipulation. And to increase adhesiona primer is applied. It is the last. Often, rather than it, putty is applied to the surface. This will allow you to create an even and smooth construction. If you do not do so, then the covering layer of plaster will probably be demanding. Sometimes you need precisely this property. And how long should plaster warm before puttying? Everything depends on the type of composition. This may be found out to the packaging out of the products.
- It ends up that the putty on the final plaster is a common thing. It is allowed to apply putty, moreover, it must even be accomplished.
Since the leveling layer can be thick, so the technologies of utilizing plaster entails the usage of beacons and net. Beacons – guides, thanks to which a coating of any thickness is obtained evenly and without differences across the length of this wall. Beacons form a section where plaster is stretched by a rule. And the mesh utilized for reinforcement involving layers averts plaster from cracking, crumbling and coming from the surface.
According to the definition, a putty is really a paste-like or powdery material used prior to the use of facing material in interior decoration. They permit you to get a perfectly horizontal surface, smooth and of top quality, that may be painted or recorded with binders.
