This work concerns a feasibility study about the possibility to evaluate the state of conservation of the monumental and historical stone and mortar surfaces with a micro-sandblasting system composed by a micro-sandblasting device and a micro-photogrammetry. The former creates a shallow crater on the surface operating at con-stant conditions (pressure of the jet, distance nozzle-surface), while the latter let us to quantify the volume of the crater through a 3D digital reconstruction. The work was focused on the validation of the methodology selecting the best operative condi-tions. To this aim, a set of tests were carried out on small glass specimens followed by tests made on natural stone materials and mortars. The results obtained have out-lined the repeatability of the data and the possibility to discriminate among natural stone materials and mortar having different physical characteristics and mechanical behaviours.
