Many traditional technologies which are used in construction remained invariable throughout long time, but even they can be mechanized. Process of mechanization has affected also stucco work, having increased at the same time their quality and considerably having lowered labor costs. The mechanized plaster which is carried out by means of special machines has allowed to increase significantly cost efficiency of this type of construction jobs.
Features of use of the mechanized plaster
It is possible to put with this way any including gipsosoderzhashchy plaster mixes for finishing of the premises and buildings calculated on stay in them big the number of people – buildings of inhabited, public and social purpose. By means of special mechanisms the production and drawing finishing mortars on walls and floors is possible if it is about bulk. The solutions received thus are more oxygenated and have high utilization properties which cannot be reached at production by hands.
The main difference of this method is the minimum use of manual work at production of plaster mixes which quality depends not only on observance of proportions, but also on technology of mixing. The latest plaster stations allow to prepare solution in the automatic mode excluding human factor, process at the same time does not demand either manual mixing, or control. Ready solution can move under the big pressure upon remote objects which can be at the height of 10-15 m and be distributed by uniform layer on the walls of the big area, however all this happens to participation of the professionals having certain skills.
Work of the plaster station requires only electric energy source, the water and dry mix coming to the tank in certain proportions. The turned-out solution is exposed to thorough mechanical stirring as a result of which it is saturated with oxygen and its properties improve. Ready solution moves on the processed surface and is at once leveled, walls turn out ideally equal and their further processing is not necessary any more. In week or it is possible to glue wall-paper one wall less or to put fair covering.
Before putting mechanical plaster of wall it is necessary to clean from dust and to degrease for the best adhesion - hitch of finishing mortar with wall surface.
Advantages of the mechanized plaster
The automation of preparation of solutions excluding manual work allows to receive the oxygenated mixes of uniform consistence which are not containing dry lumps. The solution moving under pressure provides good adhesion on all area of the processed wall. It is excluded the subsequent spackling works that allows to reduce terms of performance of finishing work and to reduce amount of dust and dirt. Reduction of necessary number of experts allows to reduce significantly the prices of stucco work, receiving at the same time better result.
The used materials
By production of the mechanized plastering different dry construction mixes are used that considerably expands range of application of this equipment. Except traditional finishing mortars, the mechanized stations work with bulk floors, also use them for preparation and putting fine mixes: putties, waterproofings. It is in certain cases reasonable to prepare in them mixes with the polymeric fiber containing the modifying additives which need more time to react with water in large number. For preparation of finishing mortars in the mechanized stations also plaster blends which term of hardening is shorter, than at traditional are used. For finishing of walls it is enough to apply plaster plaster in one layer while cement mixes put in 3 layers.
Technology of the mechanized stucco work
The team of experts from 3-4 people equipped with all necessary equipment and the tool is necessary for plastering of walls by the mechanized method. Use of special nozzles will allow to increase the performance of the station and to reduce labor costs. The finishing mortar is preparing just before the beginning of works. Dry plaster mix moves in installation via the special bunker, in the camera of the mixer it is diluted with water and kneaded. The set proportions are controlled and maintained in the automatic mode.
Productivity of one crew using method of the mechanized putting plaster averages 150 square meters for one shift.
The ready finishing mortar through hose sleeve moves to the worksite and is sprayed on surface of previously prepared and processed wall. After that intervention of professionals who level wall is necessary, removing surplus of solution and adding it to those places where it is not enough. That the surface was ideally plain, alignment is made by means of long palettes, and control vertical position by means of construction levels. In one or one and a half hours the solution applied mechanically begins to grab and dry up. After it dries, walls it is necessary to jam, process corners and joints of surfaces. In several days it is possible to start fine finish of the plastered walls.
