Method for cleaning and etching from a metal surface and other materials is the release from an abrasive under pressure pneumatically. By the impact from the abrasive particles on the material being processed follows the surface layer. Its main advantage over other methods is that it provides the surface roughness providing excellent adhesion for subsequent treatments and ensures complete removal of all traces of rust and thus being able to meet the regulations requirements and the technical datasheet of the finishing products . Urbana IDR has available its own necessary equipment and the staff trained in this type of technical work and all that it is so important to ensure the correct functioning of subsequent products.
