The definition of plaster is as follows – it is a finishing layer, which can be shaped after the curing of the building mixture. It is used to apply to a untreated surface (concrete, brick, wood) of an erected structure and allows you to accomplish a rough leveling of the walls. The layer can achieve several centimeters.
There are two big groups of plaster:
And if the first functions just as a foundation layer, which will then be applied finishing, and then the decorative is used as 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 would like to know what the difference between a simple plaster and putty, we will not touch the cosmetic mixes. To summarizethe cosmetic mixes differ in their structure, their granularity is greater, and their plasticity is significantly less.
Regular plaster is divided into different forms, depending upon the Primary component in the composition:
Formerly, plaster blends based on clay proved quite common. It is good to decorate and insulate wooden buildings. However, its performance characteristics aren’t happy. Since the price of the product is reduced, plaster can be 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 are blended with water. It’s these mixes are best for residential buildings positioned in areas where there is a good deal of noise (train stations, airfields, houses near stadiums, etc.).
The principal difference between plaster and putty is the thickness of this coating applied. As stated by the technology, plaster is permitted to use masterprofnastila.ru both a thin coating (a few mm) and a thick 1 (more than 1 cm). The application process itself may be divided into various stages:
- The Way of spraying or sketching. Spattering is carried out by way of a mechanical instrument. The process is quick and simple. Sketching is performed manually with a trowel or master. The main goal is to smooth out any imperfections in the wall, creating a base coating of fixation on the surface.
- After plastering or screeding, it is crucial to employ a smoothing coating. It may be a couple of layers. It will help to build up the thickness of the coating on the walls and to stretch the plane. And to raise adhesiona primer is applied. It’s the last. Often, instead of this , putty is applied to the prepared surface. This will let you create an even more smooth arrangement. Sometimes you need precisely this property. And how long should plaster warm before puttying? All of it depends on the sort of composition. This may be discovered on 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, additionally, it must even be carried out.
Considering that the leveling layer may be thick, then the technology of utilizing plaster entails the use of beacons and net. Beacons – guides, thanks to which a coating of any depth is accessed evenly and without differences along the length of this wall. Beacons form a part on which plaster is stretched by a rule. Along with the mesh utilized for reinforcement involving layers averts plaster from cracking, extending and coming from the surface.
According to the definition, even a putty is really a paste-like or powdery material used before the application of confronting substance in interior decoration. They allow you to get a perfectly horizontal surface, smooth and of top quality, that can be painted or recorded with binders.
