Mechanized wall plastering, reviews of which can be found more and more often, is a method of applying a solution to the surface using a special apparatus, without the participation of any additional assistants, which significantly reduces the cost of work, reduces 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 supplies a solution under pressure. Using this method, it was possible to eliminate many processes, including mixing, delivery and application of the substance to the surface. Plastering walls in a mechanized way, reviews of which indicate its effectiveness, significantly reduces the cost of repairing apartments, allowing you to also reduce the time spent on the implementation of work, eliminating a lot of negative points, in particular stains andfocal application due to the fact that the substance is mixed evenly. This method provides opportunities for rapid processing of 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 time-consuming and costly, but now everything has become much easier. The most popular option was mechanized plastering using PFT RITMO M, reviews of which speak in favor of the need to choose this particular option.
An important advantage of this method is the absence of the need for filling 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 through the putty in 1 layer, after which the surface is sanded.
Benefits
Mechanized wall plaster, reviews of which you may be interested in, is made using modern technology. This approach ensures a high quality end result. The special principle of mixing allows you to make the mixture homogeneous. This is made possible by 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. Mixtures that are used for application by machine,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 production are noticeably reduced.
If you are interested in which is better - mechanized or manual plastering, reviews of 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 suitable 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 produce a single-layer alignment, applying a layer up to 50 mm thick. The surface does not need to be treated with putty.
The principle of operation of the plastering station
At the moment, several manufacturers are engaged in the production of plastering stations: PFT (Germany), M-TEC (Germany), Putzmeister (Germany). The most widely used technique of the first of them. This is a high quality piece of equipment that comes with a spare parts kit.
Mechanized wall plaster, reviews of which testify to its high quality and speed of work, is structurally divided into two zones: for dry mix and for ready mortar. The dry mix ends up in a receiving hopper, after which it is fed through a special feed drum into the mixing chamber. In this container, it is mixed with water by means of a mixing spiral. After that, the finished mortar mixture flows to the pump,pumping it through the mortar hose. The machine can be started at any time, no matter how full the container is with dry mix. There is no need to wait until the material is completely used up to load or stop the machine.
Working principle
- a continuous supply of dry building mix is made into the receiving hopper of the station;
- the substance is dosed into the mixing chamber, after which it is mixed with water in a certain percentage;
- the screw mortar pump supplies the solution from the mixing chamber under pressure through the mortar sleeve;
- in parallel with this, compressed air is supplied to a special nozzle, and then the solution from the nozzle is sprayed onto the surface.

Technology of work performance
Reviews of mechanized plastering 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 delivery of the unit itself and the entire set of tools to the place of work is carried out. The unit is being installed at the workplace. After that, you can prepare the surfaces to be treated.
Before starting work, it is required to clean all surfaces from formwork lubricant, concrete sagging, mounting adhesive, masonry mortar and other protrusions of more than 10 mm, and protruding metal elements should be cut off and protected from corrosion. All loose areas of the surface are either fixed or removed. Concrete monolithic or panel bases, as well as surfaces that have been painted, gypsum-fiber, gypsum plasterboard, tongue-and-groove slabs must be dedusted and primed with "Betonkontakt" applied with a brush or roller.
Surfaces lined with either silicate or ceramic bricks, foam concrete, cinder concrete, aerated concrete and other materials that are characterized by high absorption must be treated with a Grundermittel primer or a similar fixing and penetrating composition. To apply the primer in this case, an airbrush or maklovitsa is used, which ensures increased efficiency of dust removal.
Surface Marking
Mechanized wall plaster, reviews of which may seem interesting, is applied after the verticality of the surfaces has been checked. For 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 provide information about the protruding spot itself. Room corners are checked using corner templates or corner rules. Next, the surfaces are marked for setting beacons. Plaster in a mechanized way, reviews of which inspire confidence, is made in the same way as by the manual method: only after the beacons are installed and fixed.
Applying process
Reviews about mechanized plastering speak in favor of the need to follow the operating instructions. In accordance with it, it is required to load a dry mix. The mortar gun should be at a distance of 20-30 cm from the surface in order to release a stream of mortar strictly perpendicular to it. Next, stretch your hands forward with a mortar gun, and then open the air cock. The solution is applied with uniform movements towards and away from oneself with the obligatory overlap of each previous line with a new one. The thickness of the layer during application is directly dependent on the speed at which the gun moves. Before you start filling the entire surface, it is worth filling in the corners and joints.
Surface shaping
The process of leveling the mortar andthe formation of the final version of the surface takes approximately 30-50 minutes from the moment the solution was applied, or until the expiration of the period for maintaining its mobility. After the solution is applied, it should be pre-leveled by pulling along the beacons. If there is not enough mortar in some places, it should be added and leveled.
Cutting the solution on the formed surface is carried out approximately 40-60 minutes after application or 15-30 minutes after its leveling is completed. The readiness of the surface of the finished solution for "cutting" is checked as follows: a rule is applied to it, after which it is pulled along it. If only the top layer is removed using the rule and the entire mass of the 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 plastering of the walls, the reviews of which you are interested in, is carried out very quickly, therefore, if some effort is required to “cut off” the surface layer, this indicates that the moment was missed. In this case, leveling the surface will be a little difficult.
