The definition of plaster is as follows – it is a finishing coating, which can be formed after the curing of the building mixture. It’s used to apply to an ominous surface (concrete, brick, and timber ) of an constructed structure and permits you to achieve a rough leveling of the walls. The coating can reach several centimeters.
There are two large groups of plaster:
And in the event the first serves only as a base layer, which will then be applied concluding, and then the cosmetic is used as the last layer. The mix is protected from most of negative environmental factors and lets you make a beautiful texture on the surface. But because we would like to know what the difference between a simple plaster and putty, we won’t touch the decorative mixes. To summarize, the cosmetic mixes differ in their structure, their granularity is higher, and their plasticity is significantly less.
Ordinary plaster can be divided into several types, depending on the Primary element in the essay:
Formerly, plaster mixes based on clay proved quite popular. It is great to decorate and decorate wooden buildings. However, its performance characteristics aren’t happy. Since the price of this product is low, plaster can be used for finishing agricultural structures.
To reach a rough leveling appropriate compositions of its production. These are cement-sand combinations, and compositions of lime and similar elements. They’re blended with water. It is these combinations are ideal for residential buildings placed in places where there is a masterprofnastila.ru lot of sound (train stations, airfields, homes near stadiums, etc.).
The major difference between plaster and putty is that the thickness of this coating applied. As stated by the technologies, plaster is permitted to employ both a thin coating (a few mm) plus a thick 1 (more than 1 cm). The application process itself may be divided into several stages:
- The Way of massaging or spraying. Spattering is performed by way of a mechanical tool. The process is fast and simple. Sketching is done manually with a trowel or master. The principal aim is to smooth out any imperfections in the wall, developing a base coat 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 coating on the walls and to stretch the plane. Each layer of plaster must dry, only then can you proceed to more manipulation. And to raise adhesion, a primer is applied. It’s the last. Many times, instead of this , putty is applied to the prepared surface. This will allow you to make an even more smooth construction. If you don’t do this, then the covering layer of plaster will probably be rough. Sometimes you need exactly this property. And just how long should plaster dry before puttying? It all depends on the form of composition. This can be found out to the packaging out of the products.
- It ends up the putty on the finished plaster is a frequent thing. It’s permitted to apply putty, additionally, it should even be done.
Since the leveling coating could be thick, the technologies of applying plaster requires the usage of beacons and mesh. Beacons – manuals, thanks to which a coating of any depth is obtained evenly and with no gaps across the length of this wall. Beacons form a part where plaster is stretched by a rule. And the mesh employed for reinforcement involving layers prevents plaster from cracking, crumbling and coming from the surface.
According to the definition, even a putty is really a paste-like or powdery substance used before the use of confronting substance in interior decoration. They allow you to get a perfectly flat surface, smooth and of high quality, that may be painted or taped with binders.
