Paint won't stick

[WaveyDave]

Hello

I've recently had my whole house re-skimmed, and new celings put up/skimmed. I've started painting yesterday, and found a patch where there seem to be splatts/run marks, and I just can't cover it up. I'm using Dulux Trade Supermatt (watered down to 3 parts paint 1 part water as per tin).

I suspect this is spilled PVA from when the plasterer was skimming the ceiling. Is there anything I can do? Cover it with a light coat of eggshell or get some Zinisser BIN? I'm also having troube covering some of the corner beading, where the plaster isn't as deep, so its not covering so well.

here are some pics

any help gratefully received.

Hello mate,

spot on with your assesment PVA for sheer ease I would line the lot and start on a blank canvas Zinser will work just be carefull about putting it on real thick and leaving the brushmarks in it cos you will see it through the emulsion when its rolled on. Don't water your paint anymore just put it on the wall, two or three coats, if you go down the zinser route. You can try some undercoat on the beading if its not covering with the paint, bear in mind that you have tried to paint it with watered down paint so give it a go with full strength first just to see. let us know how you get on.

Thanks for the advice.

I'm not overly concerned about this particular area, because it will be behind a wardrobe. I'm a bit worried that I'm going to find this elsewhere though, so I think I'll get some Zinsser in. Would you say that the BIN would be more suitable than the Bullseye?

Should I spot cover, or do the whole wall to make sure it blends/covers nicely.

Thanks

Dave
