I'm hoping to remove acoustic tile from a ceiling that was originally
nice textured plaster (plaster-board). The ceiling was subsequently
sheetrocked over, and I'd like to take all of the modifications down.
The issue is that the acoustic tile was glued directly to the plaster
with some sort of adhesive. When the tile is torn down, it leaves
globs of rock-hard brown adhesive which is terrifically resistant to
scraping or chipping.
I have tried some of the more common solvents in hopes of softening
this stuff, but no luck. Anybody have any idea what might help?
Any tips appreciated..!
