ABSTRACT
Although the response of some of these mat - erials (i.e. dammar and mastic varnishes) to commonly employed laser irradiation protocols (i.e. 248 nm) has been studied in the past (Srinivasan et al. 1989, Georgiou et al. 1998, Fotakis et al. 2006), little attention has been paid to the composition and properties of the underlying surfaces and their role to the cleaning process. Their contribution gets particularly important in the case of cleaning interventions in which the whole film of the polymeric coating must be removed (i.e. altered consolidation treatments).
