What's a good paint for covering over an old ceiling that was painted green donkey's years ago? We're using Crown brilliant white matt emulsion, but the old stuff still shows through as a discoloration after three coats of white.
Dulux "Trade" emulsion has a vastly greater covering power than the retail ones. Go to a decorators merchant, rather than one of the sheds.
+1, dulux. Leyland & glidden are also good, but dulux covers best.

For total obliteration I'd use Toolstation Trade Undercoat.
I would be tempted to use one of the paint sealers used to prevent the staining from watermarks showing through.

I have a similar issue on some vinyl wallpaper, but even the trade stuff seems to still let the pattern through according to friends, but ehn I can't see it myself..:-) Brian
There's always "stain blocker". I've had to use it following water stains on old plaster.
overpriced paint

Not necessarily, (well it might be over priced, but it doesn't mean it's not useful)
In the last house we had some stain/mark on the ceiling that kept coming through. IIRC I tried some oil based undercoat but that didn't stop it. A tin of the stain blocking paint worked a treat.
I don't know what it is specifically, but it was smellier than standard oil based paint.
but, it works

...because of its stain blocking abilities....

the point is try paint first, oil based undercoat usually does it. Stain block can be used later for the minority of tougher stains. Most yield to alkyd undercoat & emulsion.
