Someone applied Latex paint over oil paint.

Latex paint typically will not stick well.to oil paint. If you paint Latex over oil, it will peal off. It can be done, but there is a process. Definitely requires a prep and then applying a coat of fresh start primer on top of the oil paint and then Latex on top of that..
