Has anyone had success removing plaster from interior brick walls to expose the brick beneath? Would like to have the brick as the finished surface when removal is complete. It looks like a major portion of the plaster can be removed with a flat shovel. Are chemicals needed to remove the rest, or is sand blasting the recommended method? If chemicals, which ones and where can they be purchased? Thanks!

If you don't want to damage the surface underneath, then I'll bet walnut shells would be your best bet after removing what you could with a flat shovel and scraping.
