I am planning on doing some touch ups to the finish in our home…first off I have a couple rooms which were painted with BJ eggshell finish paint high hide(latex) over an old oil paint ( I didn’t do it). Unfortunately the latex is chipping away in places. I would like to repaint the rooms entirely. What preparation should I do to the walls to ensure a better adhesion with the new paint and what type paint would you recommend.
Second, there are dark stained baseboards and casings in a room which are marked up from years of wear and tear. Without having to go to the expense of replacing or repainting, I would like to know whether a light sanding and restaining with a regular stain of the same colour would brighten them up.
Your suggestions would be greatly appreciated.

Chris: Is a BJ paint job like a BS one?
I don't think you will like the answer that I suspect you already know. The previous surface was not completely cleaned, and there is not much you can do about that except remove the old paint.
I don't care WHAT people tell you, latex paints (the good ones, that is) will stick to an oil base paint, because after a few years the resin has completely cured and will not react with the latex.
The problem with latex paints is that they are much more fussy about the surface. Oil base paints will often dissolve grease and oil, and allow the resin to contact the wall. Latices won't. So, you have to scrub the wall clean. Roughening a gloss surface is always good.
Good luck.
Oh, yes. If you can find a REAL paint store, with people that think, you should be able to get some decent advice on materials to use to clean and perp the surface for best results. Don't even think about those big boxes for help.
*For interior work I have put latex over oil with some frequency. Usually trim. As John said the surface should be clean and scuffed up a bit. It is actually pretty easy to sand entire walls with a dry wall sanding pole. Since the latex/over oil is already there and pealing in spots, getting it all off to me is unrealistic. I would scrape off all the loose stuff I could find. Sand and clean those spots. Spot prime and then paint the whole thing. Save the extra paint and in the future scrape and touch up any spots that peal again.
