The growing need to preserve our cultural heritage is causing a rise in the demand for increasingly accurate cleaning techniques, featuring high selectivity and low impact.


Furthermore, the outcomes of the most recent research allow the use of increasingly flexible lasers on work sites: the optic-fiber laser beams featuring optimized pulses eliminate side effects such as possible yellowing of the stone surfaces. Laser may be used also to clean surfaces from painted graffiti: since the paint to remove has been absorbed, the traditional systems of chemical cleaning will need to be used as well, but the laser technique will make the intervention significantly less invasive.

As a matter of fact, the chemical treatment will only involve a very limited portion of paint, and will cause less risks of dispersion and penetration of the colored pigments.
