My friend and I recently painted the walls of my living room and dining room, and she made a comment to me. She said for the trim I need to be sure I get the right kind of paint. She said if I paint over the trim with the wrong paint, it will just peel off. Speaking of peeling off, the paint on my bathroom door is peeling off in large sheets Was this a case of someone using the wrong paint? So, how do I know what type of paint is on my woodwork and what type of paint I am supposed to use to paint my trim
