The definition of plaster is as follows – it is a finishing coating, which can be shaped after the healing of the building mixture. It’s utilized to apply to an untreated surface (concrete, brick, timber ) of an constructed structure and permits you to reach a rough leveling of these walls. The layer can attain several centimeters.
There are two big groups of plaster:
And in the event the first functions just as a foundation layer, which is then going to be applied finishing, and then the decorative is utilized as the final layer. The mixture is protected from all negative environmental variables and lets you create a more beautiful texture in the surface. To summarize, the decorative mixes differ in their arrangement, their granularity is higher, and their plasticity is less.
Ordinary plaster is divided into different forms, depending upon the main component in the essay:
- The selection of plaster is dependent upon the substance where the walls have been made. By way of instance, concrete or brick walls are finished with concrete compositions. But lime compositions will match walls made of silicate.
Previously, plaster combinations based on clay were very common. It is fantastic to decorate and decorate wooden buildings. However, its performance characteristics aren’t happy. Since the price of the product is low, plaster is used for finishing agricultural buildings.
To accomplish a rough leveling suitable compositions of its own production. All these are cement-sand mixtures, also compositions of lime and similar elements. They’re mixed with water. To get a plaster coating to have thermal and soundproofing attributes, foam glass, sawdust masterprofnastila.ru, polystyrene foam could be inserted into it. It is these combinations are great for residential buildings positioned in places where there’s a good deal of noise (train stations, airfields, houses near stadiums, etc.).
The principal difference between plaster and putty is that the thickness of the coating applied. According to the technology, plaster is allowed to apply both a thin coating (a few mm) plus a thick one (greater than 1 cm). The application process itself may be divided into various stages:
- The Way of spraying or sketching. Spattering is performed by means of a mechanical instrument. The process is quick and simple. Sketching is done manually using a trowel or even master. The most important purpose is to smooth out any imperfections from the wall, developing a base coating of fixation on the surface.
- After plastering or screeding, it’s crucial to apply a smoothing layer. It could be a couple of layers. It helps build up the depth of the layer on the walls and to elongate the plane. Each layer of plaster needs to dry, only then can you proceed to more manipulation. And to increase adhesiona primer is used. It is the last. Often, rather than this putty is applied to the surface. This will allow you to create an even and smooth arrangement. If you don’t do this, then the covering layer of plaster will be rough. There are times that you need precisely this property. And how long should plaster dry before puttying? All of it depends on the type of composition. This may be discovered on the packaging out of the products.
- It turns out the putty about the finished plaster is a common thing. It’s permitted to employ putty, additionally, it should even be done.
Since the leveling layer can be thick, so the technology of applying plaster includes the usage of beacons and net. Beacons – guides, thanks to that a layer of any depth is obtained evenly and with no differences over the length of this wall. Beacons form a section where plaster is elongated by means of 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 material used prior to the application of confronting material in interior decoration. They permit you to have a perfectly flat surface, smooth and of high quality, that can be painted or recorded with binders.
