How do you paint over a wall that has a thin layer of glaze ragged over the wall paint?
Answers:
If the glaze is adhering, then there is no need to remove it. If it's a latex glaze, then treat it like any latex paint (adhesion isn't usually a problem between coats of latex). Wipe a spot with liquid sandpaper. If it wipes off easily, then it's latex. If it holds up better, then it's alkyd. If it's an alkyd glaze, wipe it with a liquid sandpaper until it bites (use in a well ventilated area, and don't drive immediately afterward afterward) then prime it while it's still fresh to get a strong bond between coats. Don't use a latex primer because it will react negatively with the liquid sandpaper.
Adhesion problems are not usually related to the latest coat, but some previous coat. Each coat of paint puts a little bit of pull on the previous coat as it dries. with each coat, the tension increases down to the weakest coat where it falls off. This is why it's so important to always get good adhesion between coats.
Whether latex or alkyd, if it's a stain glaze you should use a stain sealing primer to keep the stain from bleeding through
Other answers:
Any good primer should do the job nicely.
If your are worried, get Kilz brand, that is designed for these sorts of problems.
The primer with give your paint 'teeth' to grab on to your new color.
If you are going with a darker color, have the paint store, tint your primer also. Will save you that extra coat of paint.

there is nothing special about glaze. it should be no problem to paint right over it. as the other answer mentioned, if you are doing a drastic color change, priming is a great idea, and definitely get the primer tinted. Kilz is fine, but you DO NOT need to use the oil-based. Latex Kilz2 will work fine. just remember-support your local paint store. they will be more knowledgeable/helpful than lowes/homedepot/walmart.
both previous answers are great. just remember ventilation, if you use kilz. it's not great on lungs,
The ragging has cause to much texture rub your hand across it and see.
What you need to do is skim with sheetrock mud lightly where theres not much sanding and than re-paint or Kitz and use flat paint maybe if you get lucky it will hind some of the texture. I do faux finishing.
