The definition of plaster is as follows – it is a finishing coating, which is shaped after the curing of the building mixture. It is used to apply to a ominous surface (concrete, brick, and timber ) of an erected structure and permits you to attain a rough leveling of these walls. The coating can attain several centimeters.
There are two big collections of plaster:
And in the event the first serves only as a foundation layer, which will then be applied concluding, and then the decorative is used as the last layer. The mix is protected from most of negative environmental factors and allows you to make a more beautiful texture in the surface. To summarizethe decorative mixes differ in their structure, their granularity is higher, and their plasticity is less.
Regular plaster can be divided into different forms, depending on the main element in the composition:
Formerly, plaster blends based on clay were quite common. It’s a good idea to decorate and insulate wooden buildings. However, its performance attributes are not happy. Since the price of the product is low masterprofnastila.ru, plaster can be used for completing agricultural buildings.
To attain a rough leveling suitable compositions of its production. These are cement-sand combinations, and compositions of lime and similar elements. They’re mixed with water. For a plaster coating to possess thermal and soundproofing attributes, foam glass, sawdust, polystyrene foam may be added to it. It is these combinations are best for residential buildings positioned in areas where there’s a lot of sound (train stations, airfields, houses near stadiums, etc.).
The main difference between plaster and putty is the thickness of the coating applied. According to the technology, plaster is allowed 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 stages:
- The method of spraying or sketching. Spattering is carried out by way of a mechanical tool. The process is quick and simple. Sketching is done manually using a trowel or even master. The principal goal is to smooth out any imperfections from the wall, developing a foundation coating of fixation on the face.
- After plastering or screeding, then it’s crucial to apply a smoothing coating. It may be one or more layers. It will help to build up the thickness of this coating on the wall and to stretch the airplane. And to increase adhesion, a primer is used.
- The covering layer. It’s the last. Frequently, rather than it, putty is applied to the surface. This will allow you to make an even more smooth structure. If you don’t do so, then the covering layer of plaster will probably be demanding. Sometimes you need exactly this property. And how long should plaster dry before puttying? Everything depends on the form of composition. This may be discovered to the packaging from the products.
- It ends up the putty on the finished plaster is a common thing. It is permitted to employ putty, additionally, it should even be done.
Since the leveling layer may be thick, so the technology of applying plaster entails the use of beacons and net. Beacons – guides, thanks to that a coating of any depth is accessed evenly and without gaps over the length of the wallsocket. Beacons form a section on which plaster is stretched by means of a rule. Along with the mesh utilized for reinforcement between layers averts plaster from cracking, crumbling and coming from the surface.
According to the definition, a putty is really a paste-like or powdery material used before the use of confronting substance in interior decoration. They allow you to find a perfectly flat surface, smooth and of top quality, that can be painted or taped with binders.
