How do you repair polyurea coatings?

Selected Answers

From Warren Brand of Chicago Corrosion Group on June 13, 2019:
Great question - really complex answer. We just did a project like this which I wrote about here ( The short answer is you must do adhesion testing. You can prep the PU either by physical abrasion or by chemical adhesion. There are too many variables to review here. I'm hoping staff allows the link in this response. It's an interesting case study, if I do say so myself.

From Ted Valoria of Sponge-Jet, Inc on June 13, 2019:
Sponge blasting is an ideal way to repair and remove polyurea from metal or concrete substrates. Unlike traditional abrasive blasting or power tooling that generate frictional heat, causing the coating to soften and get “gummy," when abrasive blasting with sponge media, the frictional heat does not occur, allowing the abrasives (even softer abrasives) to profile or fully remove polyurea up to 100 mils thick.
