Method of shot blasting of various surfaces represents the effect of an abrasive on the treated area, which is supplied by a stream of air at high speed. An air-abrasive stream is created that easily and reliably removes rust, scale, small burrs, and any kind of dirt from structures. Shot blasting will make it possible to obtain a rough surface with a sufficiently high degree of adhesion to a layer of applied coloring compounds. The process can take place in special shot blasting chambers in a closed space. There is an open treatment method for cleaning the upper part of the surfaces from the outside. Shot blasting machines are mainly used for cleaning metal and concrete surfaces. In order to obtain the best result for cleaning the surface, it is necessary to choose the type of fraction for processing correctly.
