Can sheets of old tin ceiling be put back up?
My schoolhouse had molded tin ceiling on the original plaster, 14' ceiling. The ceiling had been lowered in the 1940's when the building was "housified". Over what is the kitchen area now I got the stupid idea to tear the tin off the original plaster ceiling and put it on the new lower ceiling. Shoot me now, I deserve it. This was many years ago, and I never carried the project through. It has haunted me all these years, the tearing off of the tin panels that is. I still have the beautiful tin panels but of course they are a bit battered from being torn from their moorings. Bent, some edges curled , some cuts. I'm hanging my head in shame.
My question? Is it possible to straighten old tin ceiling panels without pounding the molded designs on them flat? To redeem myself I would love to restore them to their proper place even though no one will see them at present time (there is access to the area above the new ceilings). But when I'm gone, future owners may appreciate it.
