Grouting, they are smoothing machines – the tool necessary for a huge number of work. They process concrete during the organization and conduct of activities to arrange the sexes. Almost all the irregularities of the latter need to be aligned after the completion of the solidification and setting of concrete. Similar defects that have small sizes, as well as in places that are difficult to access, removes this type of technique. There are grouting machines of several different performances: units operating in non -premised and closed spaces are equipped, as a rule, by electric motors, and used in the processing of asphalt and concrete coatings in the open air are supplied with a very powerful engine operating on gasoline. Professional processing of surfaces with a large area at the same time performs self -propelled units. Most often, grouting machines are equipped with centrifugal couplings, thanks to which the main start of the engine is carried out smoothly, and the loads on it are reduced, increasing the mechanism of life and reducing the accumulated wear. For convenience and increased mobility, the machine is supplied with folding handles that allow saving a place when transporting the product. Units differ in their purpose and dimensions of the working disk. To process surfaces adjacent to building structures, small units with a rotating ring are used, and devices with a diameter of more than 600 mm cope with the black and final alignment of concrete. In general, the grout is carried out in two stages: the so -called black processing that removes large defects, and the clean refinement of the concrete floor, which is produced by the grouting machine, which has nozzles in the form of peculiar blades, which are a direct processing tool. Disadvantage of this type of machine – their quick exit.
