Rubberizing the soles of boots and shoes for stage productions is one of those recurring tasks that fall to the crafts department. A theatre company can save literally hundreds of dollars by rubberizing in-house rather than sending shoes out to cobblers for this service, provided there's a craftsperson on staff who can do it properly.
In this photographic tutorial, I will describe one process for rubberizing using the industrial solvent-based contact adhesive, Barge. Barge has been widely used in the shoemaking industry for years, but is a known carcinogen, so extreme safety precautions are required in its use. Theatrical safety experts have recently been urging the use of an adhesive known as Synthetic Latex 1812 as a less-toxic substitute for applications in which one would otherwise use Barge. I have just obtained some 1812 and will be conducting some future experiments on its usefulness in rubberizing--look for a forthcoming post soon!
For now though, 1812 is far from a universally-used substance in this application, and many shops do still use Barge for rubberizing. Thus, I'll write up the Barge process here first!
