Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates.
DIRESCO is one of the few companies in Canada trained and certified to provide this specialty service. Laser ablation is especially designed to restore surfaces to their original state leaving normal wear in place. This cleaning technique is used on heritage buildings, monuments, paintings to name a few applications.
