After removing the baseboards and chair rails from our dining room, some of the paint peeled. We are pretty sure it's all latex paint (water-based) and there is no oil-based paint base (the house was built in 2003). We are going to prime and repaint all walls. What should we do to prep the walls with peeling paint? Seems like we should peel all peeling paint off, but it is also pulling some of the drywall paper off with it.
