The definition of plaster is as follows – it is a finishing coating, which can be formed after the curing of the building mixture. It’s utilized to apply to an untreated surface (concrete, brick, and timber ) of an amalgamated structure and permits you to achieve a rough leveling of these walls. The coating can attain several centimeters.
There are two large collections of plaster:
And if the first functions only as a foundation layer, which is then going to be applied finishing, and then the decorative is used as the last layer. The mix is protected from most of negative environmental variables and allows you to make a gorgeous texture on the surface. But since we would like to learn what the distinction between a simple plaster and putty, we won’t touch the decorative mixes. To summarize, the decorative mixes differ in their arrangement, their granularity is higher, and their plasticity is less.
Regular plaster is divided into several types, depending on the main element in the composition:
Formerly, plaster blends based on clay were rather popular. It’s fantastic to decorate and insulate wooden buildings. Yet, its performance characteristics aren’t satisfied. Since the price of this product is low, plaster is used for completing agricultural buildings.
To reach a coarse leveling appropriate compositions of its own production. All these are cement-sand mixtures, also compositions of lime and similar elements. They are mixed with water. It’s these mixes are perfect for residential buildings positioned in areas where there is a good deal of sound (train stations, airfields, houses near stadiums, etc.).
As stated by the technology, plaster is permitted to employ both a thin coating (a few mm) plus a thick 1 (greater than 1 cm). The application process itself can be divided into various stages:
- The method of massaging or spraying. Spattering is carried out by means of a mechanical instrument. The process is fast and simple. Sketching is performed manually with a trowel or master. The chief goal is to smooth out any imperfections in the wall, creating a base coating of fixation on the surface.
- After plastering or screeding, it is crucial to employ a smoothing coating. It may be one or more layers. It helps build up the thickness of this coating on the wall and also to elongate the airplane. And to increase adhesiona primer is applied. It is the last. Often, instead of it, putty is applied to the prepared surface. This will let you make an even more smooth arrangement. If you do not do so, then the covering layer of plaster will probably be rough. There are times that you need precisely this property. And how long should plaster warm before puttying? All of it depends on the form of composition. This can be found out to the packaging from the products. masterprofnastila.ru
- It turns out the putty on the final plaster is a common thing. It is allowed to employ putty, moreover, it should even be carried out.
Considering that the leveling layer can be thick, the technology of applying plaster requires the usage of beacons and net. Beacons – manuals, thanks to which a coating of any thickness is accessed evenly and without gaps over the length of the wall. Beacons form a section on which plaster is elongated by means of a rule. And the mesh employed for reinforcement involving layers averts 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 before the use of confronting substance in interior decoration. They permit you to receive a perfectly horizontal surface, smooth and of top quality, which can be painted or taped with binders.
