TITLE(s): STONE REPAIRER (stonework) alternate titles: sticker
Mends broken marble slabs to restore them to usable condition, using either of following methods:
(1) Cleans broken surfaces with wire brush. Heats surfaces with gas torch. Smears shellac evenly
over heated surfaces from stick while playing torch flame on stick to thoroughly melt shellac.
Presses broken surfaces of slabs tightly together and wipes surplus shellac from joint. Clamps
sections together and allows shellac to dry. May drill holes into opposing surfaces of broken slab
sections with drill press or portable electric drill and join broken slab sections with dowel pins
in addition to shellac. (2) Lays broken grooved sections of slab wrong side up on bench and fits
them together. Heats marble along groove with blowtorch. Inserts sulfur-coated steel rod to
completely fill groove (sulfur expands during cooling to lock rod in groove). Scrapes off excess
sulfur and allows joint to set.
