Repainting 101

My daughter decided to paint her bedroom and now she says the paint isn't sticking to the baseboard, it is peeling off. I was hoping I wouldn't need to get involved in this project. I told her to sand the baseboard before painting, and I gave her some very fine emery sandpaper and a small block of wood, but she asked me to confirm what she needs to do first, so here I am.

I saw a thread called "Latex over alkyd primer" and I don't really understand it. This is what I got out of the thread. The existing paint is probably over 20 years old so the baseboard might be "linseed oil based" paint. So she needs to paint over this with a primer. Correct? or sand and then prime and then paint?

'scuff' sanding would be appropriate, then primer/paint, yes.
however, around here, we always have to ask.....
"What brand of paint is it that's peeling off?"

The new paint could be blame but the biggest factor would have to be the older oil you are painting over. Use a 100 grit sand paper for scuffing. Fine paper just won't really leave any grooves deep enough for the paint or primer to grab onto. The I would prime with Oil. Some people will say a good bonding latex primer will be fine, but I have seen them fail. Give it a light sanding after you prime as you could have picked up some boogers. Paint away with a good quality Latex Paint.
