Is toothing of brick an acceptable way to stop and start a day's work? Does it provide a stronger joint than just stepping the brick?
Toothing of brick masonry is not as good. Toothing is a nearly vertical termination of a masonry wall, in which the end stretchers of alternate courses project. Toothing makes it very difficult to fill joints adequately and achieve proper bond. New masonry walls should be terminated at a vertical expansion joint or, if the wall is to be continuous, the termination should have successive courses racked back. This way, when work continues, masons can lay up the units normally instead of pointing the joints between two projecting units. In some instances, toothing masonry is necessary. For example, when filling in a door or window opening with masonry, racking back the masonry is not practical. In these cases, the mason must take exceptional care to ensure that mortar is packed completely in the joints for the full depth of the units.
