Used to evaluate surface hardness, microdrilling (DRMS) is a very sensitive technique and its use in this field is expected to contribute for more precise results. The diversity of the composition of the mortars and the systematic presence of abrasive components are limiting factors for the use of this method in this field. In this study, several mortars with different composition and hardness are compared, using drilling resistance as the comparative parameter. The mortars were applied on site aiming at their use in real situations and some samples were tested in laboratory, using conventional techniques complemented by others currently used for on site characterization of materials. The results also highlight the need of having an integrated perspective of laboratory and on site information.
