I bought my first older home (1928) some time ago, and it took alot of effort and time to prep and paint the interior. When we got to the point of the bedroom doors we didn't know what to do, so we left them as is until we got more energy to tackle them. (Sorry, I guess you don't really need to know any of that.....)

They're wood doors of some type. It seems like the entire door has shellac on them, but in order to make the hallway the same color, the previous owner painted over the shellac. The paint is chipping off in some areas. I'd like to remove the paint, but I was hoping someone could tell me what the easiest way to get it off would be. I don't want to damage the door, and since I'm fine with the shellac on the other side, I'd like to only have to remove the paint and be done.

Also, from the house shifting, some of the doors are very tight when they close or just can't make it closed. Is there a way to fix this?

Thank you!!
