FEATURED, LIBRARIES, Main Library

There are many methods of wet abrasive blast cleaning (WAB) in surface preparation to remove coatings.

Since the 1980’s, Carolina Equipment and Supply Co. (CESCO) has been supplying WAB equipment  along with recycling methods.

Recently CESCO sent me two youtubes to directly compare traditional dry abrasive blast cleaning and Wet Abrasive Blast Cleaning using their AquaMiser (TM) equipment. I would like to share the youtubes with you.
