Williamson Masonry Junior practices ribbon jointing techniques during the repair of a campus dormitory designed by Frank Furness

Ribbon joint finishing was a popular tooling technique for both brick and stone masonry in the US until the post war era. When done correctly, ribbon joint profiles can create an illusion of a finer and more detailed joint profile while continuing to provide the necessary structural strength for the masonry wall. When executed incorrectly however, it can cause significant damage to the structure, not only aesthetically, but structurally by trapping moisture in the jointing and hastening the deterioration of the masonry.

This course will examine the correct methods of executing rule raised ribbon joints in masonry structures. Participants will be introduced to the tools needed, the process of executing the rule raised finish as well as appropriate cleaning techniques of the finish.
