Control joints refer to one-piece accessories designed to create artificial planes of weakness where minor stresses can dissipate without forming cracks. Their placement is a function of the designer and should be located on the drawings. Control joints should be wire tied to the lath. Comes with removable tape.

They are a function of the plaster assembly, not the structure. For this reason AMICO can only recommend the traditional point of view that control joints are to be wire-tied to the lath and not fastened to the structure. By wire-tying down one side of the joint and then tying the other side, the lath can be brought taut creating a preferred substrate for the application of the finish.
