Laser cleaning of paving

A combination of laser cleaning and chemical cleaning – after several years, the pavement in the restaurant was contaminated with rust, which over time leaked from the metal legs of the tables after wiping. Unfortunately, the owner tried to remove the rust with various chemicals, which most likely converted the iron oxides into dark phosphates and formed various insoluble complexes on the pavement. Most of them were removed with a laser , impurities that did not react to radiation of the used wavelength were removed with a suitable agent.www.lsrservices.cz
