Demonstration announcement from Michael Scott, Assoc. AIA:
"SpongeJet technology is used to remove graffiti, paint, lead-based paint, rust and other materials from substrates like wood, metal and concrete without damaging the substrate. This is a relatively new system of airblasting using a soft, sponge-like media that contains chemicals that adhere to paint, rust, etc but do not damage the substrate.
The demonstration will be held at the Del Monte Cannery in Alameda, CA on January 23 from 1 to 2pm. The site can be accessed from the Fortman Marina gate at 1535 Buena Vista Ave.
This event is being sponsored by the Western Chapter of the Association for Preservation Technology."
