The definition of plaster is as follows – it’s a finishing coating, which is shaped after the masterprofnastila.ru healing of the construction mixture. It is used to apply to an ominous surface (concrete, brick, and timber ) of an erected structure and allows you to attain a rough leveling of these walls. The coating can attain several centimeters.
There are two big groups of plaster:
- Regular.
- Decorative.
And in the event the first serves only as a foundation layer, which will then be applied finishing, and then the cosmetic is utilized as the final layer. The mixture is protected from most of negative environmental factors and lets you create a gorgeous texture on the surface. To summarizethe cosmetic mixes vary in their structure, their granularity is higher, and their plasticity is significantly less.
Ordinary plaster has been divided into several types, depending upon the Primary component in the essay:
Previously, plaster combinations based on clay were rather common. It’s a good idea to decorate and insulate wooden buildings. But, its performance attributes aren’t happy. Since the price of the product is reduced, plaster can be used for finishing agricultural buildings.
To reach a rough leveling suitable compositions of its own production. All these are cement-sand combinations, also compositions of lime and similar elements. They’re mixed with water. To get a plaster coating to possess thermal and soundproofing qualities, foam glass, sawdust, polystyrene foam could be inserted into it. It’s these mixes are perfect for residential buildings positioned in areas where there is a lot of sound (train stations, airfields, homes near stadiums, etc.).
According to the technology, plaster is allowed to use both a thin coating (a few mm) plus a thick 1 (more than 1 cm). The application process itself may be divided into several phases:
- The Way of massaging or spraying. Spattering is performed by way of a mechanical tool. The process is fast and simple. Sketching is done manually with a trowel or even master. The major objective is to smooth out any imperfections in the wall, developing a foundation coat of fixation on the surface.
- After plastering or screeding, it’s crucial to employ a smoothing layer. It may be a couple of layers. It helps build up the depth of the coating on the wall and also to elongate the plane. And to raise adhesion, a primer is used.
- The covering coating. It’s the last. Often, instead of this , putty is applied to the surface. This will let you create an even more smooth structure. Sometimes you need exactly this property. And just how long should plaster warm before puttying? It all depends on the sort of composition. This can be found out on the packaging out of the products.
- It ends up the putty on the finished plaster is a frequent thing. It’s allowed to employ putty, moreover, it should even be accomplished.
Considering that the leveling layer can be thick, so the technology of utilizing plaster includes the use of beacons and mesh. Beacons – manuals, thanks to which a layer of any depth is obtained evenly and with no differences across the length of this wallsocket. Beacons form a part on which plaster is stretched by a rule. Along with the mesh employed for reinforcement involving layers prevents plaster from cracking, extending and coming from the surface.
According to the definition, even a putty is really a paste-like or powdery substance used prior to the application of facing substance in interior decoration. They permit you to acquire a perfectly flat surface, smooth and of high quality, that may be painted or taped with binders.
