My first callback...

Well...

A local school district is a regular client of mine, I do several classrooms for them each year. Last year I did a bathroom for them in their middle school.

I prepped the walls with a TSP wash and a good rinse followed by several days of dry time. The surface felt dry and clean and I rolled 2 coats of BM Aura SG. Now the kids are having fun peeling the paint off the walls in strips.

Silver lining - they're doing some of the prep for me.

So...I need to remedy this and I'm wondering what to do differently. I figure I'll start with a wide sharp knife and get everything off that I can in big sheets. Then I'll attack it with a more aggressive sander in my lineup and some low grit paper. It's not a ton of square footage, there's tile up to ~4ft. Then I'm thinking another cleaning, product to be determined, followed by primer and the usual topcoats.

I'd love any recommendations on product or process. Thanks!

I'd ask Mr. Burt. Good luck now.

Stix primer.

The comment about 'peeling in strips' has me thinking there was a bonding problem.  Is the BM Aura rated to cover an oil-based paint?  Perhaps a cleaner used by the school custodians got under the paint?

The existing finish I painted over was an acrylic, not an oil base. Regardless, after a good wash and sand a primer like Stix should serve as a good intermediary between the new and the old.

Your custodial cleaner theory seems plausible, and this time my prep will need to be thorough enough to account for whatever traces of old cleaner could have been on there.
