Abstract: The restoration of the Galerius Palace in Thessaloniki was carried out from 1994 up to 2006, including removal of eroded mortars and replacement by compatible mortars, reconstruction of brickworks, restoration of floor mosaics. A significant number of compatible repair mortars was used, based on the systematic study and analysis of the existing ones. Written instructions were given for the in situ preparation and application of the different type of repair mortars, which could be characterized as lime-based mortars. An archive of all works was also kept by the supervisors. In this paper a detailed survey of repair with lime-based is presented, including macro and micro scale photos, description of damages and other relevant remarks. Furthermore, analysis of mortar samples, showed volume stability and strength of them. Local environmental conditions and other accidental reasons were taken into account for interpreting the results. Generally, it could be said that the respond of the applied repair mortars to the functional requirements of their position in the ancient structure was very good.
