We remove corrosion and old coatings using laser cleaning and mobile blasting . Where blasting is not possible due to environmental pollution (interiors, structures near buildings, in the presence of people, etc.), where there is undesirable contamination with abrasive dust (industrial operations) or where the surface of the steel structure must not be disturbed, we clean the surfaces using a laser . We have developed technological procedures supplemented by mechanical cleaning (manual grinding, brushing) with subsequent laser cleaning and surface preparation according to ČSN EN ISO 8502 . Cleaning of structures is followed by the application of two-component polyurethane and/or epoxy industrial coatings.
