The definition of plaster is as follows – it is a finishing coating, which is formed after the curing of the building mixture. It’s used to apply to a infested surface (concrete, brick, timber ) of an constructed structure and permits you to attain a rough leveling of the walls. The coating can achieve several centimeters.
There are two big groups of plaster:
- Regular.
- Decorative.
And if the first serves only as a base layer, which will then be applied concluding, then the cosmetic is used as masterprofnastila.ru the last layer. The mix is protected from most of negative environmental variables and lets you create a gorgeous texture in the surface. But since we wish to know what the difference between a simple plaster and putty, we are not going to touch the cosmetic mixes. To summarize, the decorative mixes vary in their arrangement, their granularity is higher, and their plasticity is less.
Regular plaster is divided into different types, depending upon the Primary element in the composition:
Previously, plaster combinations based on clay proved very common. It is good to decorate and decorate wooden buildings. However, its performance attributes aren’t happy. Since the price of the product is low, plaster is used for finishing agricultural buildings.
To reach a rough leveling appropriate compositions of its production. These are cement-sand mixtures, and compositions of lime and similar components. They’re mixed with water. To get a plaster layer to possess thermal and soundproofing attributes, foam glass, sawdust, polystyrene foam could be inserted to it. It’s these combinations are perfect for residential buildings positioned in areas where there’s a good deal of noise (train stations, airfields, homes near stadiums, etc.).
As stated by the technology, plaster is permitted to employ 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 carried out by way of a mechanical tool. The process is quick and simple. Sketching is performed manually with a trowel or master. The main 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’s crucial to employ a smoothing coating. It may be one or more layers. It will help build up the thickness of this layer on the walls and to elongate the airplane. And to raise adhesiona primer is used.
- The covering layer. It’s the last. Many times, rather than this putty is applied to the surface. This will let you make an even and smooth construction. 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 can 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 allowed to employ putty, moreover, it must even be accomplished.
Since the leveling layer can be thick, the technology of utilizing plaster entails the usage of beacons and net. Beacons – manuals, thanks to that a layer of any thickness is obtained evenly and with no differences over the length of this wallsocket. Beacons form a part on which plaster is elongated by means of a rule. And the mesh utilized for reinforcement between layers averts plaster from cracking, crumbling and coming from the surface.
According to the definition, even a putty is a paste-like or powdery material used before the application of facing substance in interior decoration. They permit you to get a perfectly horizontal surface, smooth and of top quality, that can be painted or taped with binders.
