Damaged bottom edging of tin ceiling cornices
franklen

We inherited a room with an old tin ceiling that was painted white. We are going to paint again, but the edge of the cornice that meets the wall is very damaged from rust around most of the room, and there is a gap between the cornice and the top of the drywall edge when new drywall was installed in the room. My thought is to buy some new narrow cornices that we would install around the room over the bottom of the old cornice and spanning the small gap onto the new drywall. Does this make sense to do? Alternatively, we thought about using drywall tape and mud to cover the gap and the bottom of the cornice. Picture links below.

The last thing you should do is install drywall mud against the metal, I would go with a narrow cornice.

Or you could cover it with a new molding, crown or other, all around the ceiling.

Thanks so much. Will not do drywall, other research has confirmed that. Thin strip of cornice around the room would be much more affordable than a new full crown or molding, so likely going that route. Someone used the word lattice to present the same solution, not sure what they meant by lattice as opposed to cornice? Anyone have a thought about that?

The pics have me confused; the close-up showed missing paint but no loss or rust. The general pic showed what looked to be missing material, but again it looked bright not rusty where the paint had peeled.
You could take a grinder and cut off the entire lower edge, then add blocking material behind and replace with wood crown (or other similar) molding.
You could also make a mold in place (look at www.abatron.com for mold-making kits) and cast replacement material in plastic. I have made "irreplaceable" carved moldings several times with this method.

Compare new cornice metal with crown molding and go with which one you like best. Nice to see you keeping the ceiling :D
