Mechanized wall plastering, reviews of which can be found more and more often, is a way of applying the solution to the surface using a special device, without the participation of any additional assistants, which significantly reduces the cost of work, shortens the time for its implementation, and also improves the result. The name itself indicates that a special machine is used as a device for applying, which delivers the solution under pressure. Using this method, it was possible to exclude many processes, including mixing, delivery and application of the substance to the surface. The plastering of walls in a mechanized way, the reviews of which indicate its effectiveness, significantly reduces the cost of apartment renovation, while also reducing time costs for the implementation of works, eliminating a lot of negative aspects, in particular spots and focal deposition due to the fact that the substance is mixed evenly. This method provides the ability to quickly process large areas. The process is carried out with a long spatula to achieve optimal surface smoothness. Previously, the stage of leveling the walls and plastering them was the most lengthy and costly, but now everything has become much simpler. The most popular option was plaster mechanized using PFT RITMO M, reviews of which speak in favor of the need to choose this option.
An important advantage of this method is the absence of the need for putty work. The mechanized method of applying plaster ensures that the walls are ready for wallpapering immediately after drying. If you want to apply paint or some kind of decorative coating that requires special smoothness, then you need to go putty in 1 layer, after which the surface is sanded.
Benefits
Mechanized wall plastering, reviews of which you may be interested in, is made using modern technology. This approach ensures high quality of the final result. The special mixing principle makes the mixture homogeneous. This became possible due to the fact that the plaster is added to the water, and not vice versa. Mechanized plaster, reviews of which speak of its instant setting, adheres to the surface very quickly due to its supply under pressure. Mixes that are used for machine application are much more expensive than those designed for manual work. The surface plastered in this way does not need to be puttied before wallpapering. The terms and cost of work are markedly reduced.
If you are interested in what is better - mechanized or manual plastering, reviews from those who have tried both methods will help you make a choice. It is important to note here that gypsum-based ready-made mixtures are more acceptable for use than cement-sand ones. Natural gypsum gives them whiteness, and the porous structure makes them environmentally friendly. With their help, it is possible to perform single-layer alignment, applying a layer of up to 50 mm in thickness. The surface does not need to be putty treated.
The principle of operation of the plaster station
At the moment, several manufacturers are engaged in the production of stucco stations: PFT (Germany), M-TEC (Germany), Putzmeister (Germany). The most widely used technique was the first of them. This is a high quality equipment that comes with a set of spare parts.
Mechanized wall plaster, reviews of which testify to its high quality and speed of work, structurally has a division into two zones: for dry mix and for ready-made mortar. The dry mixture is in the hopper, and then fed through a special feed drum into the mixing chamber. In this container, it is mixed with water through a mixing spiral. After this, the finished mortar mixture arrives at the pump, which pumps it through the mortar hose. The machine can be started at any time, it does not matter how much the tank is filled with dry mix. To load or stop the unit, it is not necessary to wait for the full production of material.
Principle of operation
- in the receiving hopper of the station is a continuous supply of dry mortar;
- the substance is dosed into the mixing chamber, after which it is mixed with water in a certain percentage ratio;
- a screw mortar pump delivers the solution from the mixing chamber under pressure along the mortar sleeve;
- parallel to this, compressed air is supplied to a special nozzle, and then the solution from the nozzle is sprayed onto the surface.
Description of some stations
Mechanized wall plaster, reviews of which you are probably interested in, is powered by 220 or 380 volts. There are stations of different voltages, differing in the volume of work performed. When assessing the upcoming volumes, it is required to determine which station will be most used.

Work execution technology
Reviews of mechanized plaster speak in favor of the fact that this is a convenient and quick way of surface treatment, which requires certain preparatory work. To begin with, the unit itself and the entire set of tools are delivered to the place of work. The unit is being installed at the workplace. After this, it is possible to carry out the preparation of the machined surfaces.
Before starting work, all surfaces must be cleaned of shuttering grease, sagging concrete, mounting glue, masonry mortar and other protrusions of more than 10 mm, and protruding metal elements should be cut off and protected from corrosion. All non-fixed surface areas are either fixed or removed. Monolithic concrete or panel substrates, as well as surfaces subjected to staining, gypsum-fiber, gypsum plasterboard, tongue-and-groove plates, must be dusted off and primed with "Concrete contact", applied with a brush or roller.
Surfaces lined with either silicate or ceramic bricks, foam concrete, slag concrete, aerated concrete and other materials that are characterized by high absorption, must be treated with a Grundermittel primer or similar fixing and penetrating compound. For applying a primer, in this case, an airbrush or a maklovitsa is used, due to which increased dust removal efficiency is ensured.
Surface marking
Mechanized wall plastering, reviews of which may seem interesting, is applied after the verticality of the surfaces has been checked. To do this, a wide level is used, the length of which is 2-3 meters, and in the horizontal direction the check is carried out using a template or cord. The test results give information about the most prominent place. The corners of the rooms are checked using corner patterns or a corner rule. Further surfaces are marked for lighthouses. Plastering in a mechanized way, reviews of which are credible, is done in the same way as in the manual method: only after the beacons are installed and fixed.
Application process
Mechanized reviews of the plaster speak in favor of the need to follow the instructions for use. In accordance with it, it is required to load the dry mixture. The mortar gun should be at a distance of 20-30 cm from the surface in order to let out a stream of solution strictly perpendicular to it. Next, you should stretch your arms forward with the mortar gun, and then open the air cock. The solution is applied with uniform movements to and from itself with the obligatory overlapping of each previous line with a new one. The thickness of the layer during application is in direct proportion to the speed with which the gun moves. Before you start filling the entire surface, it is worth filling the corners and joints.
Surface formation
The process of leveling the solution and the formation of the final surface option takes about 30-50 minutes from the moment the solution was applied, or until the expiration of its mobility. After the solution is applied, it should be pre-leveled, pulled along the beacons. If in some places there was an insufficient amount of solution, it should be added and leveled.
The solution is trimmed on the formed surface approximately 40-60 minutes after application or 15-30 minutes after completion of its leveling. The readiness of the surface of the finished solution for “pruning” is checked as follows: a rule is applied to it, after which it is stretched along it. If using the rule only the top layer is removed and the entire mass of material is not affected, this indicates readiness. If there is a contraction of the entire mass, then a little more time is required. Another important point is that the mechanized wall plastering, reviews of which you are interested in, is carried out very quickly, therefore, if certain efforts are required to “cut” the surface layer, this indicates that the moment was missed. In this case, leveling the surface will be a little difficult.
