Sorry to tell you but its difficult to make a perfect job when you repair pebble dashing but if you want to do it your self cut around the area in a zig zag patten /\/\/\ its called dog toothing then simply render back up with a 4 sand to 1 cement mix and flick stones that match back on useing a dashing trowel
hope it helps
