I just wanted to say *thank you* to whoever
(someone on this list, but I've lost the original answer to my
query) suggested painter's tape as a buffer between the walls, the
double-sided tape, and the foam core board when mounting the latter to the
former.
I just took down the most recent temporary
exhibit in the museum where I was having such a hard time with panels either
falling off randomly or melding so tightly with the wall that they were almost
impossible to pry off (sometimes right next to each other), and it was like
night and day. The panels stayed up for the entire year, yet they came
right off when I was ready for them to, with no damage to panels or wall.
I will never mount another foam core panel onto
wood or drywall without painter's tape. What a simple, inexpensive
solution. That worked.
