CONSERVATION AND RESTORATION OF ARCHAIC STONES OF ANCIENT CITIES OF EUROMOS AND IASOS – DEVELOPMENT OF NEW POLYMERS FOR THE PROTECTION OF ARCHAIC STONES

In particular, innovative hydrophobic compounds to be used as protective agents have been designed, synthesized, tested on Turkish quarry marble samples, and compared with some commercial products. In situ tests with the same compounds used for the laboratory experiments have also been carried out. The innovative compounds belong to the partially fluorinated polymers (oligoamides with pendant perfluoropolyether segments). Tests for the evaluation of the efficacy and durability of conservative treatments, in relation to the environmental conditions which the stones are submitted, have been properly identified and realized. These compounds have been studied and tested on laboratory, also as well as in situ. Several organic/inorganic treatments have been performed in the laboratory and in situ to select the more suitable compounds and application methodologies for consolidation and protection of these ancient stones.
