Not as a long-term solution. If only the joints with separations are to be corrected, the laborer or pointer must identify the vulnerable joints. Some readily identified separations may extend only a short distance into the joint.

Some readily identified separations may extend only a short distance into the joint. Others, which appear smaller on the surface, may penetrate entirely through the thickness of the wall and may actually be more of a problem. Applying standard mortar over the face of the existing joint is not a durable repair. Instead of having 3/4-inch contact with the brick, the feathered edge of the mortar smear may have almost no contact at all. The portion of the new mortar which contacts the brick may readily weather. Also, if any movement occurs at all, the separation will readily reopen, because little bond has been achieved.
