The definition of plaster is as follows – it is a finishing coating, which can be formed after the curing of the building mixture. It is utilized to apply to a infested surface (concrete, brick, and timber ) of an constructed structure and allows you to reach a rough leveling of the walls. The coating can reach several centimeters.
There are two large groups of plaster:
And if the first functions just as a foundation layer, which will then be applied concluding, then the decorative is used as the final layer. The mix is protected from all negative environmental factors and lets you create a gorgeous texture in the surface. To summarize, the decorative mixes vary in their arrangement, their granularity is higher, and their plasticity is significantly less.
Ordinary plaster is divided into several forms, depending on the Primary component in the essay:
Previously, plaster blends based on clay were quite popular. It is very good to decorate and decorate wooden buildings. But, its performance attributes are not satisfied. Since the purchase price of the product is low, plaster is used for completing agricultural buildings.
To accomplish a coarse leveling suitable compositions of its production. All these are cement-sand mixtures, and compositions of lime and similar components. They are blended with water. For a plaster coating to possess thermal and soundproofing attributes, foam glass, sawdust, polystyrene foam could be inserted to it. It is these combinations are excellent for residential buildings placed in places where there’s a great deal of sound (train stations, airfields, homes near stadiums, etc.).
The most important difference between plaster and putty is the thickness of the layer applied. According to the technologies, plaster is permitted to use both a thin coating (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 way of a mechanical instrument. The process is fast and simple. Sketching is done manually using a trowel or even master. The principal goal is to smooth out any imperfections in the wall, developing a base coat of fixation on the surface.
- After plastering or screeding, then it’s crucial to employ a smoothing layer. It can be a couple of layers. It will help build up the thickness of this layer on the wall and also to elongate the airplane. Each tier of plaster needs to dry, only then can you proceed to further manipulation. And to raise adhesiona primer is applied. It is the last. Many times, rather than it, putty is applied to the prepared surface. This will allow you to create an even and smooth structure. There are times that you need precisely this property. And just how long should plaster dry before puttying? Everything depends on the kind of composition. This can be discovered on the packaging out of the products.
- It ends up that the putty on the final plaster is a common thing. It is allowed to employ putty, additionally, it must even be done.
Since the leveling coating can be thick, so the technologies of applying plaster involves the use of beacons and net. Beacons – manuals, thanks to which a coating of any depth is accessed evenly and without differences across 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 off the surface.
According to the definition, even a putty is really a paste-like or powdery material used before the use of facing material in interior decoration. They allow you to get a perfectly horizontal surface, smooth and of high quality, that may be painted or taped with binders.
