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.
