Comparison of Wet Abrasive Blast (WAB) and Dry Abrasive Blast Cleaning

Posted on 04. Feb, 2016 by in Flash Rust, Gallery

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.

    That is really cool that water blasting took less time than dry cleaning did. That would be something that I would like to have if it saved me even a few minutes of time. This is something that I am going to have to look into soon so that I can get stuff done faster.

    There are times when dry blast is appropriate, when wet abrasive blast is appropriat, and when Waterjetting is appropriate. I didn’t get your email earlier.
