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!
