Maintaining an aesthetic and attractive appearance of a building requires the use of special means. Such events are not limited to ordinary window maintenance, since the appearance of the facade is also formed by decoration materials. The content of the lining, in turn, sets the goal not only of the external refinement of the surface, but also of providing additional protection against external destructive influences. In other words, facade cleaning is a wide range of cleaning operations, the nature of the use 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, you can not do without the traditional means of mechanical cleaning. Rough processing of the facade in this way justifies itself when it is necessary to eliminate old layers of plaster, putty or the remains 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 it is necessary to update the appearance of the old building, this cleaning allows you to prepare the surface for further restoration or decoration of the exterior walls.
Sandblasting the facade
This is just the case when you can talk about new technologies for delicate and efficient cleaning. The work uses a pneumatic tool with a compressor unit, which acts on the surface using sand abrasive blown from the nozzle of the apparatus. The user can vary the intensity of the air flow with particles, changing both the coverage area and the degree of impact on the site. Sandblasting of building facades, in essence, refers to the same mechanical methods, but with modern improvements. The operator can control the processing characteristics, practically without applying his own efforts during the operation.
In terms of the quality of the result, this method is considered one of the best. Peskostruy can be involved in the spot work with historical objects during their restoration, and in the maintenance of large areas. For example, if it is necessary 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 working parameters of the tool correctly.
Steam generator cleaning
The elevation of the facade includes at least two work steps. Firstly, this is the aforementioned cleaning, which is carried out mainly by machining. Secondly, it is a sink that saves the surface from 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, which due to steam treatment allows you to remove old stubborn dirt from various surfaces. Such a washing takes place under high pressure, which increases the efficiency of eliminating even technogenic 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.
The use of chemicals and reagents
If you need to quickly bring a large area of a heavily soiled facade into proper shape, then you can hardly do without chemical assistants. Effective mechanical action in such cases is useless, but in combination with correctly selected reagents, and they allow you to efficiently complete the tasks. The fact is that a classic brush with a metal pile, of course, will allow you to completely clean a small area, but when working with a multi-story building, this tool is not practical to use without a special preparation. So, chemicals for cleaning the facade rid the walls of complex and old deposits, including rust and soot. In professional cleaning, reagents such as UHDO and Armex are preferred. Their peculiarity lies in the fact that during processing only traces of contaminants are eliminated, and the base surface retains its original structure.
Features of working with sunflowers
One of the most common problems faced by brick house owners. Vysoli is a plaque formed during the interaction of brick salts and moisture, which inevitably comes into contact with the outer surface during precipitation. Unfortunately, to get rid of this kind of pollution neither traditional detergents nor abrasive effects help. Of course, machining will help to remove such deposits, but along with them the outer layer of the cladding will be eliminated. The solution may be blasting - this is a special facade cleaner that represents a group of pneumatic tools. Unlike sandblasting, this technique does not require the use of an abrasive - cleaning is carried out using an air stream, in which there may be water or a 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 preserving 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 pollution - from soot to efflorescence. Partially, mechanical processing helps to cope with such raids, but in some cases the gentle washing of facades with blasting and steam generators is also effective. The important differences between such tools include their energy efficiency. They require minimal energy 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.
