The paper presents the results of a research study aimed at assessing the effectiveness of composite-reinforced mortar (CRM) for the seismic strengthening of existing stone masonry walls. The experimental research focused on the strengthening performance of a coating applied only on one side of the masonry wall. Such an application is interesting because it does not require the temporary relocation of residents. The historic two-wythe stone masonry used in the research represents Adriatic’s coastal and surrounding regions. The coating was made of hydraulic lime mortar reinforced with a glass fibre–reinforced polymer mesh attached to the wall using two types of anchors. In-plane cyclic shear compression tests and cyclic out-of-plane tests were conducted, and the performances of the coating on one and both sides were compared. The results showed that the coating on one side was effective, improving all aspects of the seismic response, which was successfully simulated using existing design models.
