The definition of plaster is as follows – it’s a finishing coating, which can be shaped after the healing of the construction mixture. It’s used to apply to a ominous surface (concrete, brick, and wood) of an erected structure and allows you to accomplish a rough leveling of these walls. The coating can reach several centimeters.
There are two big groups of plaster:
And in the event the first serves just as a base layer, which will then be applied concluding, then the decorative is utilized as the final layer. The mix is protected from all negative environmental variables and allows you to make a more beautiful texture in the surface. But since we would like to learn what the difference between a simple plaster and putty, we won’t touch the cosmetic mixes. To summarize, the cosmetic mixes vary in their arrangement, their granularity is higher, and their plasticity is less.
Ordinary plaster can be divided into different forms, depending upon the Primary element in the composition:
- The option of plaster is dependent upon the material from which the walls have been made. As an instance, concrete or brick walls are finished with cement compositions. But lime compositions will match walls made from silicate.
Previously, plaster mixes based on clay were rather popular. It is very good to decorate and insulate wooden buildings. Yet, its performance features aren’t happy. Since the purchase price of the product is low, plaster can be used for completing agricultural structures.
To accomplish a rough leveling suitable compositions of its own production. All these are cement-sand mixtures, and compositions of lime and similar elements. They’re blended with water. To get a plaster layer to have thermal and soundproofing attributes, foam glass, sawdust, polystyrene foam could be inserted to it. It’s these combinations are best for residential buildings placed in places where there is a great deal of noise (train stations, airfields, homes near stadiums, etc.).
According to the technologies, plaster is permitted to apply both a thin coating (a few mm) plus a thick 1 (more than 1 cm). The application process itself can be divided into various stages:
- The Way of massaging or spraying. Spattering is carried out by means of a mechanical tool. The process is quick and simple. Sketching is done manually using a trowel or even master. The primary intention is to smooth out any imperfections in the wall, developing a foundation coating of fixation on the surface.
- After plastering or screeding, it is crucial to employ a smoothing layer. It can be a couple of layers. It helps to build up the thickness of this layer on the walls and also to elongate the airplane. Each layer of plaster needs to dry, only then can you proceed to further manipulation. And to raise adhesiona primer is applied. It is the last. Often, instead of itputty is applied to the prepared surface. This will allow you to create an even more smooth construction. If you don’t do so, then the covering layer of plaster will be demanding. Sometimes you need exactly this property. And how long should plaster dry before puttying? All of it depends on the form of composition. This may be found out to the packaging out of the products.
- It turns out that the putty about the final plaster is a common thing. It is masterprofnastila.ru allowed to apply putty, moreover, it must even be carried out.
Since the leveling coating could be thick, the technology of utilizing plaster requires the use of beacons and net. Beacons – manuals, thanks to that a layer of any depth is obtained evenly and without differences along the length of the wallsocket. Beacons form a part where plaster is stretched by means of a rule. And the mesh utilized for reinforcement between layers averts plaster from cracking, extending and coming off the surface.
According to the definition, even a putty is really a paste-like or powdery material used before the application of facing substance in interior decoration. They permit you to get a perfectly flat surface, smooth and of top quality, which may be painted or taped with binders.
