The definition of plaster is as follows – it’s a finishing coating, which can be formed after the curing of the building mixture. It is utilized to apply to a infested surface (concrete, brick, wood) of an constructed structure and allows you to reach a rough leveling of these walls. The layer can reach several centimeters.
There are two large collections of plaster:
And if the first functions only as a foundation layer, which will then be applied concluding, and then the decorative is utilized as the final layer. The mixture is protected from most of negative environmental factors and allows you to make a more beautiful texture in the surface. To summarize, the decorative mixes vary in their arrangement, their granularity is higher, and their plasticity is less.
Ordinary plaster is divided into different types, depending on the Primary element in the composition:
Formerly, plaster mixes based on clay were quite popular. It is fantastic to decorate and decorate wooden buildings. Yet, its performance characteristics are not happy. Since the purchase price of this product is low, plaster is used for finishing agricultural buildings.
To reach a coarse leveling suitable compositions of its own production. These are cement-sand mixtures, also compositions of lime and similar elements. They’re mixed with water. It is these mixes are great for residential buildings placed in areas where there is a whole lot of noise (train stations, airfields, homes near stadiums, etc.).
The most important difference between plaster and putty is the thickness of this layer applied. According to the technologies, plaster is allowed to use both a thin layer masterprofnastila.ru (a few mm) plus a thick one (more than 1 cm). The application process itself can be divided into several phases:
- The method of massaging or spraying. 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 main purpose is to smooth out any imperfections from the wall, creating a foundation coating of fixation on the face.
- After plastering or screeding, it’s crucial to apply a smoothing layer. It can be a couple of layers. It will help to build up the thickness of this coating on the wall and to elongate the plane. Each tier of plaster must dry, only then can you proceed to additional manipulation. And to raise adhesion, a primer is used.
- The covering coating. It is the last. Many times, instead of itputty is applied to the surface. This will allow you to create an even and smooth structure. If you don’t do so, then the covering layer of plaster will be rough. Sometimes you need precisely this property. And just how long should plaster warm before puttying? It all depends on the type of composition. This can be found out to the packaging from the products.
- It turns out that the putty on the finished plaster is a common thing. It’s permitted to employ putty, additionally, it should even be carried out.
Considering that the leveling layer could be thick, so the technologies of utilizing plaster involves the use of beacons and net. Beacons – guides, thanks to that a layer of any thickness is accessed evenly and with no gaps over the length of this wall. Beacons form a part where plaster is stretched by means of a rule. Along with the mesh used for reinforcement involving layers prevents plaster from cracking, extending and coming off the surface.
According to the definition, a putty is really a paste-like or powdery material used prior to the use of confronting material in interior decoration. They permit you to find a perfectly horizontal surface, smooth and of top quality, which may be painted or recorded with binders.
