The existing masonry walls are highly vulnerable to earthquakes. One of the new methods of seismic improvement of existing buildings is the use of concrete coating. This study investigated the effectiveness of enhancing unreinforced masonry (URM) walls using hybrid concrete coating (concrete with steel-glass fibers). This study was experimental and tested two sample walls on a real scale and under an in-plane cyclic loading. One sample was a reinforced wall coated with hybrid fiber concrete (HFC) on one side, and the other was a reinforced wall coated on both sides; meanwhile, an unreinforced wall served as the reference wall. The results revealed that enhancing URM walls with HFC coating provides economic benefits and work simplicity, and most importantly, avoids crack formation by creating a hardened panel. Besides, an HFC layer could considerably enhance the wall’s lateral bearing capacity, energy, and stiffness.
