The definition of plaster is as follows – it’s a finishing coating, which can be shaped after the curing of the building mixture. It is utilized to apply to a untreated surface (concrete, brick, timber ) of an masterprofnastila.ru amalgamated structure and allows you to achieve a rough leveling of the walls. The coating can attain several centimeters.
There are two big groups of plaster:
And in the event the first serves only as a foundation layer, which is then going to be applied concluding, and then the cosmetic is utilized as the last layer. The mix is protected from all negative environmental factors and lets you create a more gorgeous texture on the surface. But since we want to learn what the distinction between a simple plaster and putty, we will not touch the decorative mixes. To summarizethe decorative mixes differ in their arrangement, their granularity is greater, and their plasticity is significantly less.
Regular plaster has been divided into several forms, depending upon the main component in the essay:
- The choice of plaster is dependent upon the substance where the walls are all made. As an example, brick or concrete walls are completed with concrete compositions. But lime compositions will match walls made of silicate.
Previously, plaster mixes based on clay were very common. It is great to decorate and insulate wooden buildings. Yet, its performance attributes are not satisfied. Since the price of this product is reduced, plaster is used for completing agricultural structures.
To accomplish a coarse leveling suitable compositions of its own production. All these are cement-sand combinations, also compositions of lime and similar components. They are blended with water. It is these combinations are great for residential buildings placed in areas where there is a whole lot of noise (train stations, airfields, houses near stadiums, etc.).
As stated by the technology, plaster is allowed to employ both a thin coating (a few mm) and a thick one (greater than 1 cm). The application process itself can be divided into several stages:
- The Way of massaging or spraying. 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 main objective is to smooth out any imperfections in the wall, developing a base coat of fixation on the surface.
- After plastering or screeding, then it is necessary to apply a smoothing layer. It could be a couple of layers. It will help build up the thickness of the coating on the wall and to stretch the plane. Each tier of plaster has to dry, only then can you proceed to further manipulation. And to raise adhesion, a primer is applied. It’s the last. Frequently, instead of itputty is applied to the prepared surface. This will let you make an even and smooth structure. There are times that you need precisely this property. And how long should plaster dry before puttying? All of it depends on the sort of composition. This can be discovered on the packaging from the products.
- It turns out that the putty on the final plaster is a common thing. It is permitted to employ putty, additionally, it must even be done.
Considering that the leveling coating may be thick, the technologies of applying plaster entails the usage of beacons and net. Beacons – guides, thanks to that a layer of any depth is accessed evenly and without differences over the length of the wall. Beacons form a section where plaster is elongated by a rule. And the mesh used for reinforcement involving layers prevents plaster from cracking, crumbling and coming from the surface.
According to the definition, a putty is a paste-like or powdery substance used before the use of facing substance in interior decoration. They allow you to have a perfectly flat surface, smooth and of top quality, that can be painted or taped with binders.
