LASER CLEANING OF STONES
Conservation of stones is the application field where the laser represents an established reality in the panorama of intervention methods. The first and most common use is the removal of black crusts and inorganic superficial encrustation on architectural elements and monuments. The use of the laser does not alter but preserves all the patinas present on stones between the substrate and the degradation. There are no unwanted side effects and the intervention, even for maintenance purposes, can be repeated several times.
