In this paper the pull-off test results on CFRP laminates bonded to masonry units on stiff and flexible adhesives are presented. The flexible polymer adhesive was matched to repair the brick specimens with delaminated CFRP strips bonded on epoxy adhesive, which failed in the Single-Lap test. The same test was applied for the research on the specimens repaired with the polymer adhesive. The results demonstrate that the flexible adhesive is more effective than the stiff one because of stress concentractions reduction and stress distribution equality along the bond length and higher fracture energy.
