The conservation of historic building is important in order to maintain intact the cultural heritage value. In the present study, the consolidation and protective effectiveness of the commercial consolidant named VP5035 was investigated with respect to the well known tetraethoxysilane (TEOS). The two products were evaluated at first when applied on a very porous bio-calcarenite, i.e. Lecce stone (PL). After treatment, stone samples were investigated by different experimental techniques including scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM-EDS). Moreover, different measurements including chromatic variation, static contact angle, water capillary absorption, permeability to water vapor, surface cohesion, and resistance to weathering effect induced by salt crystallization were performed in order to assess the performance of the consolidating agent.
