The need for a dry, low dust, reusable, abrasive blasting technology was the reason a U.S. Coast Guard Industrial Support Detachment switched to using the Sponge-Jet Sponge Blasting System for surface preparation. In place of using coventional abrasives, they now Sponge Blast their 41,44, 46, 47 and 55 foot Patrol Boat interiors and exteriors. This Industrial Support Detachment uses Silver Sponge Media TM abrasives to remove an average of ten mils of epoxy topcoat and primer. Efforts to improve repair efficiency on Patrol Boats led to the following process constraints and the subsequent use of the Sponge Blasting system:
Simple Containment - The extensive containment required, when using high pressure water, to control slurry or runoff, would be cost prohibitive.
Low Airborne Dust -
