The nature of the pigment, its cohesion to the support and the nature and tenacity of the encrustation to be removed are all parameters that must be evaluated by the restorer in order to choose the most suitable laser system.

A second application – in which laser technology has proved to be decisive – is the removal of overlapping layers of lime from the pictorial surfaces (descialbo). In this case it is not a true ablation but a secondary photomechanical action that allows the detachment of the plaster to be removed. Where possible, this action is supported by gently wetting the surface of wall paintings with water.
