From Chuck Pease of MMI Tank on June 19, 2014:
When using good equipment, it is a very handy preparation tool for concrete surfaces. There are also shot blast machines for steel surfaces, good for ships' decks or tank interiors that have a door sheet cut while rehabbing. Concrete substrates can be shot-blasted adjacent to clean rooms when used with the HEPA filters and a large dust collector.   Shotblasting doesn't do well with thick-film coatings or elastomeric  films. This method, as Dan mentioned, requires that another coating will need to be applied to protect the concrete that is exposed during the shotblasting process. On uncoated concrete, you can prepare the substrate to accept coatings as thin as penetrating sealers or as thick as polymer floors or terrazo installations, depending on what ICRI concrete surface preparation is called for in the specs.

From Dan Ruark of IDS Blast on June 18, 2014:
CONS: *Time it takes *Expense *Basically means another coating will need to be applied after done or it will need to be ground back smooth. PROS: *Is a job just about anybody can do *Not very noisy *Not dusty (when proper dust collector is used) *Makes a coating last 3 to 10 times longer (at least) *Can be completed without interrupting normal workday *Allows an "anti-slip" material (such as aluminum oxide) to be added to the coating or epoxy to be applied.
