When adding a new master bath to our home last year we opted to buy salvaged doors for the room. We found some great ones that matched the sizes that we needed and were very happy. After a year of being installed 2 of the 3 are now peeling. Apparently someone painted latex paint over oil based. Some of the paint will peel off and some I have tried scraping off to prep to re-paint but if I wait about a week it will loosen up some more and begin peeling. How do I get all of this paint off so I can safely repaint? I have sc****d some down to original wood and other parts are just down 1 or 2 colors. I also have another door that we are using as an interior closet door and it was apparently an outside door at some time. I would like to retain the aged look of the door so how do I stabilize the paint that is still on the door or do I have to sc**** down to bare wood and repaint as well? HELP! I thought we were helping the environment buy re-purposing old doors but this is really turning into more work than we bargained for.
