The definition of plaster is as follows – it is a finishing coating, which can be formed after the healing of the construction mixture. It is utilized to apply to an infested surface (concrete, brick, wood) of an constructed structure and allows you to attain a rough leveling of these walls. The layer can attain several centimeters.
There are two large collections of plaster:
- Regular.
- Decorative.
And in the event the first serves just as a base layer, which will then be applied finishing, and then the cosmetic is utilized as the last layer. The mixture is protected from all negative environmental variables and allows you to create a gorgeous texture on the surface. But because we would like to understand what the difference between a simple plaster and putty, we are not going to touch the cosmetic mixes. To summarizethe decorative mixes differ in their arrangement, their granularity is higher, and their plasticity is less.
Ordinary plaster can be divided into several forms, depending on the Primary component in the essay:
- cement;
- lime;
- gypsum;
- lime-cement;
- lime-gypsum;
- cement-gypsum.
- The choice of plaster depends on the substance from which the walls are created. As an example, concrete or brick walls are finished with concrete compositions. But, lime compositions will suit walls made from silicate. masterprofnastila.ru
Previously, plaster combinations based on clay proved very popular. It is fantastic to decorate and decorate wooden buildings. But, its performance features are not satisfied. Since the price of this product is reduced, plaster can be used for completing agricultural structures.
To attain a coarse leveling appropriate compositions of its own production. These are cement-sand mixtures, also compositions of lime and similar elements. They are mixed with water. It’s these mixes are great for residential buildings placed in areas where there is a good deal of sound (train stations, airfields, houses near stadiums, etc.).
The most important difference between plaster and putty is that the thickness of the layer applied. As stated by the technologies, plaster is permitted to apply both a thin coating (a few mm) and a thick one (greater than 1 cm). The application process itself may be divided into several phases:
- The Way of spraying or sketching. Spattering is performed by way of a mechanical instrument. The process is quick and simple. Sketching is performed manually with a trowel or master. The most important intent is to smooth out any imperfections in the wall, creating a base coat of fixation on the face.
- After plastering or screeding, then it is necessary to employ a smoothing layer. It can be one or more layers. It will help to build up the depth of the layer on the walls and also to stretch the airplane. Each layer of plaster needs to dry, only then can you proceed to further manipulation. And to raise adhesiona primer is applied.
- The covering layer. It’s the last. Many times, instead of it, putty is applied to the surface. This will allow you to create an even more smooth arrangement. If you don’t do this, then the covering layer of plaster will probably be demanding. There are times that you need precisely this property. And how long should plaster dry before puttying? Everything depends on the type of composition. This may be found out to the packaging out of the products.
- It ends up that the putty about the finished plaster is a common thing. It’s allowed to apply putty, moreover, it must even be accomplished.
Considering that the leveling coating may be thick, the technologies of utilizing plaster entails the use of beacons and mesh. Beacons – manuals, thanks to which a coating of any thickness is accessed evenly and with no differences over the length of the wallsocket. Beacons form a part on which plaster is stretched by means of a rule. Along with the mesh employed for reinforcement between layers prevents plaster from cracking, extending and coming off the surface.
According to the definition, even a putty is a paste-like or powdery material used prior to the use of confronting substance in interior decoration. They allow you to acquire a perfectly flat surface, smooth and of top quality, which may be painted or taped with binders.
