The definition of plaster is as follows – it’s a finishing coating, which is 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 allows you to attain a rough leveling of these walls. The coating can reach several centimeters.
There are two big collections of plaster:
- Regular.
- Decorative.
And if the first serves just as a foundation layer, which is then going to be applied concluding, and then the cosmetic is used as the final layer. The mix is protected from all negative environmental variables and lets you make a more beautiful texture in the surface. To summarize, the decorative mixes differ in their arrangement, their granularity is greater, and their plasticity is significantly less.
Ordinary plaster can be divided into different forms, depending on the Primary element in the essay:
- cement;
- lime;
- gypsum;
- lime-cement;
- lime-gypsum;
- cement-gypsum.
- The alternative of plaster depends on the substance from which the walls are made. For example, brick or concrete walls have been finished with concrete compositions. But, lime compositions will match walls made from silicate.
Previously, plaster blends based on clay proved quite common. It is very good to decorate and decorate wooden buildings. However, its performance attributes are not satisfied. Since the purchase price of the product is reduced, plaster is used for completing agricultural buildings.
To attain a coarse leveling suitable compositions of its production. These are cement-sand mixtures, also compositions of lime and similar components. They’re blended with water. It’s these combinations are ideal for residential buildings placed in places where there is a great deal of noise (train stations, airfields, homes near stadiums, etc.).
As stated by the technology, plaster is allowed to use both a thin layer (a few mm) plus a thick one (greater than 1 cm). The application process itself can be divided into several stages:
- The Way of spraying or sketching. Spattering is performed by means of a mechanical instrument. The process is quick and simple. Sketching is performed manually with a trowel or even master. The main purpose is to smooth out any imperfections in the wall, developing a base masterprofnastila.ru coating of fixation on the surface.
- After plastering or screeding, then it’s necessary to apply a smoothing coating. It can be one or more layers. It helps to build up the thickness of this layer on the walls and also to elongate the plane. And to raise adhesiona primer is used.
- The covering layer. It’s the last. Often, rather than it, putty is applied to the surface. This will let you make an even and smooth structure. If you don’t do so, then the covering layer of plaster will be demanding. There are times that you need precisely this property. And how long should plaster dry before puttying? Everything depends on the kind of composition. This may be discovered on the packaging out of the products.
- It ends up that the putty about the finished plaster is a frequent thing. It is permitted to employ putty, additionally, it must even be carried out.
Considering that the leveling layer may be thick, then the technologies of applying plaster entails the usage of beacons and mesh. Beacons – guides, thanks to which a coating of any thickness is accessed evenly and with no gaps along the length of the wallsocket. Beacons form a part where plaster is elongated by a rule. And the mesh used for reinforcement between layers prevents plaster from cracking, extending and coming from the surface.
According to the definition, a putty is a paste-like or powdery material used prior to the application of facing material in interior decoration. They permit you to acquire a perfectly flat surface, smooth and of high quality, which can be painted or recorded with binders.
