In a context of changing environment, the preservation of outdoor built heritage is increasingly threatening. Furthermore the application of conservative products not always achieved the expected results as well as preliminary tests aimed at evaluating the performance of new products often proved to be inappropriate. In such situation, the paper reports the outcomes of the innovative methodology adopted to assess the efficiency and durability of nano-based consolidating products utilized for the conservation of carbonate artworks, carrying out field exposure tests on Carrara Marble model samples in different sites. Surface properties, superficial cohesion, distribution, penetration of the conservative products and their interactions with substrates and environmental conditions were examined and compared with the features of undamaged samples and of those artificially damaged.
