One of the main and time-consuming stages of rough finishing of a building is wall plastering. This process takes a lot of time, and if specialists are involved in the work, repair costs will increase by 2 times, which is far from always acceptable. Fortunately, technological progress does not stand still, and today mechanized wall plastering is available to us. The pros and cons, as well as the technology of the work, we will consider in this article.
What is the essence of the method?
The plastering of walls by a mechanical method differs from the process familiar to everyone in that a machine is involved in mixing the working composition and applying it to the wall. A special modular unit prepares the plaster in a large volume and feeds it through a hose for application to the surface.
Using this method allows you to draft rough premises in record time and with minimal effort. There are no particular restrictions on the use of modular machines, but it is more advisable to work with them on large objects, for example, inside private houses and in the process of processing building facades.
The plaster applied mechanically to the walls is of high quality, as the apparatus thoroughly kneads the solution. The supply of the working composition is carried out through a hose, the length of which allows you to leave the station on the street, and carry out work indoors. This simplifies the supply of dry mix and water to the device.
Advantages of using this method
The advantages of mechanized wall plastering are quite obvious: the machine allows you to create the perfect coating in a short time. However, there are a number of advantages, for which it is worth giving preference to the mechanical application of the composition. These include:
- The possibility of using a composition of the same quality. With automatic mixing of the plaster, the human factor is completely eliminated. There are no lumps in the solution, the ratio of the components is always constant, which avoids the deterioration of the composition due to improper mixing.
- Reducing the likelihood of cracking. When applying the plaster manually, the wall is processed in several steps, because of which part of the composition is already drying out and interacts poorly with the new solution. When using stations, you can cover most of the base with one run, so that the plaster layer is monolithic.
- Material saving. When evaluating the pros and cons of mechanized wall plastering, one should pay attention to the fact that automatic stirring helps to saturate the composition with oxygen, so that the mixture is more airy, material consumption is reduced.
Advantages include the fact that the surface created by the machine is smoother, which eliminates the need for multi-layer puttying of walls. It also leads to lower costs.
What are the disadvantages of mechanized wall plastering?
The use of plastering stations does not adversely affect the quality of work. The disadvantages of mechanical application of the composition are manifested in another. Namely:
- in the cost of equipment;
- the need for special care of the station;
- noisy operation of equipment;
- the need to ensure uninterrupted supply of water and electricity.
The purchase of a plaster station is relevant only for large volumes of work. However, in almost every city, such equipment can be rented.
Since the plaster quickly sets, the station needs to be washed frequently, otherwise it will quickly fail.
When assessing the pros and cons of mechanized wall plastering, one should take into account the fact that the resulting coating has a longer drying period. This is due to the fact that the manufacturers of mixtures use special additives that allow them to develop a composition before it hardens inside the station.
What compounds are used for plastering machines?
For mechanical application of plaster use special mixtures with the appropriate mark. They are produced both dry and ready-made.
If work is carried out indoors, preference is given to gypsum compositions. For plastering facades exclusively cement varieties are used.
As a rule, formulations for application by an automated method are 30% cheaper than analogues for manual work. This can be considered an additional advantage of mechanized plastering.
Technology of work
Work begins with the standard preparation of walls for applying plaster. Surfaces are cleaned of impurities, beacons are installed. Particular attention is paid to the preparation of equipment for work.
Water is supplied to a special compartment and the mixture is poured. Next, the wizard sets the program, which indicates the proportions of the main components. The machine makes the mixture, after which the process of applying the composition begins. It happens as follows:
- The master holds the gun at right angles to the wall. The distance between the gun and the wall is 25 cm.
- The mixture is applied from the corner of the room. The gun is moved from bottom to top until the wall is completely covered with plaster.
- The applied solution is leveled using a broad rule and allowed to dry. After half an hour, the surface is slightly moistened and smoothed with a grater.
Reviews of the pros and cons of mechanized wall plastering indicate that such a process of applying the composition takes 4 times less time than manual plastering. The master makes a minimum of effort, due to which the quality of work is significantly improved.
conclusions
The use of plastering stations several times reduces the time for roughing, and the final coating is characterized by high quality. The problem is only the high cost of equipment, but each technology has its pros and cons. Mechanized wall plastering was no exception. If the work must be carried out in record time, the equipment can always be rented or purchased at several construction crews.
