The definition of plaster is as follows – it’s a finishing coating, which is shaped after the curing of the building mixture. It’s used to apply to a ominous surface (concrete, brick, and wood) of an erected structure and allows you to attain a rough leveling of the walls. The coating can achieve several centimeters.
There are two large collections of plaster:
And in the event the first serves only as a base layer, which will then be applied finishing, and then the decorative is used as the last layer. The mixture is protected from most of negative environmental factors and allows you to create a more beautiful texture in the surface. But since we would like to learn what the distinction between a simple plaster and putty, we are not going to touch the cosmetic mixes. To summarize, the cosmetic mixes differ in their structure, their granularity is greater, and their plasticity is less.
Ordinary plaster is divided into different forms, depending upon the Primary element in the essay:
Previously, plaster mixes based on clay proved rather common. It’s better to decorate and insulate wooden buildings. Yet, its performance characteristics are not satisfied. Since the price of the product is low, plaster is used for completing agricultural buildings.
To achieve a coarse leveling suitable compositions of its own production. All these are cement-sand mixtures, and compositions of lime and similar components. They are blended with water. To get a plaster layer to possess thermal and soundproofing attributes, foam glass, sawdust, polystyrene foam could be added to it. It is these combinations are perfect for residential buildings placed in places where there is a great deal of sound (train stations, airfields, homes near stadiums, etc.).
According to the technologies, plaster is allowed to employ both a thin layer (a few mm) and a thick one (greater than 1 cm). The application process itself can be divided into several phases:
- The method of drawing or spraying. Spattering is performed by way of a mechanical tool. The process is fast and simple. masterprofnastila.ru Sketching is done manually using a trowel or master. The primary intention is to smooth out any imperfections from the wall, developing a foundation coating of fixation on the surface.
- After plastering or screeding, it is necessary to employ a smoothing coating. It may be one or more layers. It will help build up the depth of the layer on the wall and also to elongate the plane. Each layer of plaster needs to dry, only then can you proceed to further manipulation. And to raise adhesiona primer is used. It’s the last. Often, instead of it, putty is applied to the prepared surface. This will allow you to create an even more smooth construction. Sometimes you need precisely this property. And how long should plaster warm before puttying? All of it depends on the kind of composition. This can be found out on the packaging from the products.
- It ends up that the putty on the final plaster is a common thing. It’s allowed to apply putty, additionally, it must even be accomplished.
Considering that the leveling layer can be thick, the technology of applying plaster includes the use of beacons and net. Beacons – guides, thanks to which a coating of any thickness is obtained evenly and without gaps over the length of this wall. Beacons form a section where plaster is stretched by a rule. Along with 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 substance used prior to the application of facing material in interior decoration. They permit you to receive a perfectly flat surface, smooth and of top quality, that may be painted or recorded with binders.
