If you have a masonry fireplace and the crack is more than a hair open, you can use high temperature mortar to fill the crack. Mix the mortar in a zip lock freezer bag, then snip off a corner and squirt it into the crack. Try and pack some in with a small putty knife. Strike it off level, wipe off the excess with a damp sponge and let it cure for a week or so. The cracks usually have to get over 1/8 inch wide to cause any problem. Flames do not get into small opening very much, and the brick is relatively thick, and backed up by plain brick. |
