The definition of plaster is as follows – it is a finishing coating, which can be formed after the healing of the construction mixture. It is utilized to apply to masterprofnastila.ru an infested surface (concrete, brick, timber ) of an amalgamated structure and allows you to achieve a rough leveling of these walls. The coating can reach several centimeters.
There are two big collections of plaster:
- Routine.
And if the first serves just as a base layer, which will then be applied finishing, and then the decorative is used as the final layer. The mix is protected from all negative environmental factors and allows you to make a more beautiful texture in the surface. But since we would like to understand what the difference between a simple plaster and putty, we won’t touch the decorative mixes. To summarizethe cosmetic mixes vary in their arrangement, their granularity is higher, and their plasticity is significantly less.
Ordinary plaster can be divided into several types, depending upon the main element in the essay:
- cement;
- lime;
- gypsum;
- lime-cement;
- lime-gypsum;
- cement-gypsum.
- The option of plaster is dependent upon the substance where the walls have been created. For example, concrete or brick walls have been finished with cement compositions. But, lime compositions will suit walls made from silicate.
Formerly, plaster blends based on clay proved very popular. It is fantastic to decorate and insulate wooden buildings. Yet, its performance features are not satisfied. Since the price of the product is low, plaster is used for finishing agricultural buildings.
To attain a rough leveling suitable compositions of its production. All these are cement-sand combinations, also compositions of lime and similar elements. They are blended with water. It’s these combinations are perfect for residential buildings placed in places where there is a great deal of sound (train stations, airfields, homes near stadiums, etc.).
The primary difference between plaster and putty is that the thickness of the coating applied. As stated by the technology, plaster is permitted to apply both a thin coating (a few mm) and a thick one (greater than 1 cm). The application process itself can be divided into several phases:
- The method of massaging or spraying. Spattering is carried out by way of a mechanical instrument. The process is fast and simple. Sketching is performed manually with a trowel or master. The most important objective is to smooth out any imperfections from the wall, developing a base coat of fixation on the surface.
- After plastering or screeding, then it is necessary to apply a smoothing coating. It may be a couple of layers. It helps to build up the thickness of the coating on the walls and also to elongate the plane. And to raise adhesion, a primer is applied.
- The covering layer. It’s the last. Many times, rather than this , putty is applied to the prepared surface. This will let you create 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 warm before puttying? It all depends on the type of composition. This can be found out to the packaging out of the products.
- It turns out that the putty about the finished plaster is a common thing. It’s permitted to employ putty, additionally, it must even be accomplished.
Since the leveling layer may be thick, the technologies of applying plaster includes the usage of beacons and net. Beacons – guides, thanks to which a layer of any depth is accessed evenly and without differences along the length of this wallsocket. Beacons form a section where plaster is stretched by means of a rule. And 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 really a paste-like or powdery material used prior to the application of facing material in interior decoration. They permit you to find a perfectly horizontal surface, smooth and of top quality, that may be painted or taped with binders.
