After completing a bathroom tile job, including a tile baseboard border about 6 up from the floor, we have dried thinset in on the actual wall - places we missed during cleanup. I‘ve tried using some scrapers (plastic and metal), and the dried thinset is like concrete (naturally) and is pulling layers of drywall off with it. Is there a solvent or better way to remove the dried thinset from both the wall and the exposed rim of the tiles? As a last resort I might be okay with slight damage to the walls as they need serious prep anyway before paint, but I do want to make sure i haven‘t missed some very obvious, easier, better solution first.
all you can do short of replacing the drywall is to fill the holes with drywall patch and then sand and paint
Rip, dig or pull it off. It has to come off and there is no trick way to do it. You can mud the damage when you prep the rest of the wall for painting.
I have had tile layers do that to my drywall talking about PO! OK take a razor knife and carefully cut the paper around the grout peel paper away, then skim coat with mud, tapping mud you know loose. Best case if you are going to texture the wall if its not thick on the surface just texture it in. If a tile layer caused this tell him to pay for it or get out of town!
muriatic acid - at home crappot or lowe's
