I have a crack that's developed in a corner on my brick home. Part of the problem is that the bricklayer didn't interlace the bricks in the corner which would have eliminated the problem. Instead, he chose to butt them in the corner which means a morter joint from top to bottom. The crack is small, about 1/8" but I would like to fill it with morter. It sure would be easier if they made something I could put the morter in like a caulk tube so I could apply it evenly. Is there a tool out there for doing this?
