if that's the case , it may pay you to strip it all off - depends how far you want to go , or are you are just doing a cosmetic job

I've done the full monty and it's all off! It was only starting out as a cosmetic job..... but once it went across the ceiling I figured it would all need to come off. I have spent days scraping. Filling in and sanding next. :eek:

Im probably a thicko but wouldnt this mean you have damp in the walls?

Albany is fine. Don't worry about Bargain and Qick branded stuff for the mist coat. If the Albany is matt you can use that. Just thin it about 20/30 water 80/70 paint for the mist coat, then 10/90 for the second coat then neat for the third. If the old Dulux is Rich Matt don't bother - it won't stick If its silk bother even less!

That's great, thanks. It's a huge 10 litre pot so it will prob be enough for all of it. Have just noticed that it's vinyl matt emulsion though and I've now got an awful feeling that you're going to say I can't use that (I didn't pay for it though, so I wont feel too bad)!!!

Hmmm, I have no idea, lol!! It started peeling on an internal wall though and if it is damp I assume that would mean it's rising damp. I 'think' (hope) that it's just the previous decorators lack of mist coat which meant that the silk paint they put onto the plaster, had nowhere to 'stick' to. If it is damp, that is well out of my remit!!!

I agree, it probabaly was because it didnt have a mistcoat on.

You mentioned you have a vinyl mat to put on, it shouldnt be any problem now as the plaster is more than 6 months old.
Just thin it down for the first coat 70% paint, 30% water, and you will be okay.
if its too runny it wont do it any harm, rather mistcoat be too thin than too thick.
