Due to a leaky shower stall ( since replaced) some of the nearby

expanded or sumthin'. Can I lightly sand it and paint over it? What
would you suggest? Thanks.

Not much can be done (satisfactorily at least) w/ drywall that has been
wet other than replace it.

Well, depends on how wet for how long.

If the drywall is breaking up, replacement is the only
sensible option.

But if the water damage is minor/cosmetic, a simpler
fix might be very viable. Sand and then seal the area
with an oil based primer (Kilz or similar). Then paint.

It's worked perfectly for me a couple of times. Those
repairs are completely invisible and they were made
several years ago.
