I'm trying to fix up my little cottage on a budget; the bedrooms in my '35 home have acoustic tile glued to the ceiling. I suspect this part of the house was added at a later date (rooflines, quality of materials) which would explain why there is a "beam" running across one ceiling.
Can I attach Ply Bead to the ceiling? I think it has to run perpendicular to the joists, I'm hoping I can find it in 12' lengths. Do I have to take off the tile first? (I don't want to do that!)
The tiles are ugly and do not meet nicely at corners, so definitely need to disappear. Ideas and advice greatly appreciated!
Also: How thick should the Ply Bead be?
