Maintaining an aesthetic and attractive appearance of a building requires the use of special tools. Such events are not limited to ordinary window care, since the appearance of the facade is also shaped by finishing materials. The content of the cladding, in turn, aims not only to improve the external surface, but also to provide additional protection from external destructive influences. In other words, facade cleaning is a wide range of cleaning operations, the nature of which is determined by the requirements for a particular object.
Surface machining
Advanced cleaning technologies offer more and more solutions for the most accurate and delicate impact on work surfaces. But in some cases, traditional means of mechanical cleaning cannot be dispensed with. Rough processing of the facade in this way justifies itself when it is necessary to eliminate old layers of plaster, putty or remnants of brick cladding. Mechanical cleaning of the facade is most often done with a metal brush and a spatula, but hammers with grinders and a perforator can also be used. In some respects, this type of work can be attributed to dismantling repair operations. If necessaryrenovation of the appearance of an old building, such cleaning allows you to prepare the surface for further restoration or finishing of exterior walls.
Facade sandblasting
This is exactly the case when we can talk about new technologies for gentle and effective cleaning. In the work, a pneumatic tool with a compressor unit is used, which acts on the surface with the help of a sandy abrasive blown from the nozzle of the apparatus. The user can vary the intensity of the airflow with particles, changing both the coverage area and the degree of impact on the area. Sandblasting building facades is essentially the same mechanical methods, but with modern improvements. The operator can control the processing characteristics with little or no effort during the operation.
This method is considered one of the best in terms of the quality of the result. Sandblasting can be used both in point work with historical objects during their restoration, and in the maintenance of large areas. For example, if it is required to clean the facade from rust, then pneumatic equipment will completely fulfill this task, leaving a clean metal surface at the exit. The main thing is to choose the right working parameters of the tool.
Steam generator cleaning
Facade improvement includes at least two working stages. The first is the aforementioned cleaning, which is carried out mainly by mechanical processing. Second, it's a sinkridding the surface of dust, dirt, plaque and atmospheric deposits. The second part of the activities can be carried out with a traditional set of tools and devices, including sponges, rags, powders, brushes, etc. However, washing facades with a steam generator is increasingly practiced. This is a cleaning tool that, due to steam treatment, allows you to remove old, ingrained dirt from various surfaces. Such washing takes place under high pressure, which increases the efficiency of eliminating even man-made soot with atmospheric pollution. The advantages of steam generators include environmental friendliness. Only in rare cases, the use of such devices requires the connection of special powders and cleaning compounds.
Use of chemicals and reagents
If you need to bring a large area of a heavily polluted facade into proper shape in a short time, then you can hardly do without chemical assistants. Effective mechanical action in such cases turns out to be useless, but, coupled with properly selected reagents, they make it possible to perform the assigned tasks with high quality. The fact is that a classic brush with a metal bristle, of course, will allow you to completely clean a small area, but in working with a multi-storey building, this tool is not advisable to use without a special preparation. So, chemical products for cleaning the facade relieve the walls of complex and old raids, including rust and soot. In professional cleaning, preference is given to reagents such as UHDO and Armex. Themthe peculiarity lies in the fact that only traces of contamination are eliminated during processing, and the base surface retains its original structure.
Features of working with efflorescence
One of the most common problems faced by the owners of brick houses. Efflorescence is a plaque that forms during the interaction of brick s alts and moisture, which inevitably comes into contact with the outer surface during precipitation. Unfortunately, neither traditional detergents nor abrasive effects help to get rid of this kind of pollution. Of course, mechanical processing will help to remove such raids, but the outer layer of the cladding will also be eliminated along with them. Blasting can be a way out - this is a special facade cleaner, representing a group of pneumatic tools. Unlike sandblasting, this technique does not require the use of an abrasive - cleaning is carried out by means of an air jet, which may contain water or detergent in the form of the mentioned reagents.
Conclusion
For various reasons, the facade is a special object in terms of cleaning operations. The fact is that it requires the preservation of the original appearance of the base surface in the form of the same finish, but during operation it accumulates on it a whole range of difficult-to-remove contaminants - from soot to efflorescence. Mechanical processing helps to partly cope with such raids, but in some cases gentle washing of facades with the help of blasting and steam generators is also effective. ToAn important difference between such tools can be attributed to their energy efficiency. They require minimal electricity costs, and air and water are used as the main consumables. Of course, such devices are not cheap, but their regular operation will save a lot of time on cleaning the facade.
