I am currently working on renovating a bedroom of a split-level house built around the 60s. I removed all of old trim from the windows, doorway, and closet. There is a thick layer of paint where the old trim met the wall forming a slight bump. Should I smooth this out before installing new trim? Should I sand it? Should I use joint compound, spackle, etc.? I am not sure if the paint underneath is lead based, but I would prefer not to sand and expose that layer of paint from when the house was built.
Thanks in advance for any advice and suggestions!
