The definition of plaster is as follows – it’s a finishing layer, which can be shaped after the healing of the construction mixture. It is used to apply to a ominous surface (concrete, brick, wood) of an amalgamated structure and enables you to reach a rough leveling of these walls. The coating can reach several centimeters.
There are two large groups of plaster:
And if the first functions only as a base layer, which is then going to be applied concluding, and then the decorative is utilized as the last layer. The mixture is protected from most of negative environmental variables and lets you create a more gorgeous texture in the surface. But because we wish to understand what the difference between a simple plaster and putty, we will not touch the decorative mixes. To summarize masterprofnastila.ru, the decorative mixes vary in their structure, their granularity is higher, and their plasticity is significantly less.
Ordinary plaster is divided into different types, depending on the main component in the composition:
Formerly, plaster combinations based on clay were rather common. It’s fantastic to decorate and insulate wooden buildings. Yet, its performance attributes aren’t happy. Since the purchase price of this product is reduced, plaster can be used for finishing agricultural structures.
To achieve a rough leveling appropriate compositions of its own production. All these are cement-sand mixtures, also compositions of lime and similar components. They’re blended with water. To get a plaster layer to possess thermal and soundproofing attributes, foam glass, sawdust, polystyrene foam could be added into it. It’s these mixes are excellent for residential buildings positioned in areas where there is a whole lot of sound (train stations, airfields, homes near stadiums, etc.).
As stated by the technologies, plaster is permitted to apply both a thin coating (a few mm) and a thick 1 (greater than 1 cm). The application process itself may be divided into various phases:
- The method of spraying or sketching. Spattering is performed by means of a mechanical instrument. The process is fast and simple. Sketching is performed manually using a trowel or even master. The principal aim is to smooth out any imperfections in the wall, developing a base coat of fixation on the face.
- After plastering or screeding, then it is necessary to apply a smoothing coating. It can be one or more layers. It will help build up the depth of this coating on the walls and also to stretch the airplane. And to increase adhesion, a 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 more smooth arrangement. There are times that you need precisely this property. And just how long should plaster warm before puttying? It all depends on the form of composition. This may be discovered to the packaging from the products.
- It ends up the putty about the final plaster is a frequent thing. It’s allowed to apply putty, moreover, it must even be done.
Considering that the leveling layer can be thick, so the technologies of utilizing plaster entails the use of beacons and mesh. Beacons – manuals, thanks to that a coating of any depth is obtained evenly and with no gaps over the length of this wallsocket. Beacons form a section where plaster is elongated by means of a rule. Along with the mesh utilized for reinforcement involving layers averts plaster from cracking, crumbling and coming off the surface.
According to the definition, even a putty is really a paste-like or powdery substance used prior to the use of confronting substance in interior decoration. They allow you to receive a perfectly horizontal surface, smooth and of high quality, that can be painted or recorded with binders.
