The decay of artworks, monuments, and buildings made of stone materials is a natural and irreversible process. In order to protect stone artworks and buildings from natural decay, it is necessary to reduce the penetration of water into porous substrates by applying a highly hydrophobic protective coating on the stone surface. The performances of two nano-composite coatings containing an organo-modified boehmite nano-filler, applied on calcareous stone substrates typical of Apulia region (leccese stone, PL and gentile stone, PG), and activated by UV or sunlight radiations, were compared in order to establish the more suitable product for the specific stone substrate.
