Dear tabby, when I am answering a question about apples, why do you persist in claiming I know nothing about oranges.
And then attempting to to insult our intelligence by saying 'there, he hasn't got an answer'
Do you really think that anyone with 10% of a brain, or more, cannot see how stupid that makes you look?
I've been resisting, and I know I'll regret this, but...
I'm still wrestling with
Is there something esoteric here that I'm missing, or is the poster suggesting using PVA as a mist coat? Because if anything is almost guaranteed to make it hard for paint to stick, it's a nice coat of PVA.
Cheers Richard
I know that, I didn't pick up a paint brush yesterday. I've just no idea what you mean by glue, unless you're referring to co-polymer binders.
Cheers Richard
emulsion contains a glue, and piss coating results in a fair bit of it soaking into the substrate rather than binding the paint layer. I'm not clear what is unclear.

:
Emulsion doesn't contain a glue, unless you're referring to copolymer binders, or using something like vinyl silk, which isn't much good for a mist coat. What was unclear was your use of the term "glue", and your earlier assertion that the OP should use PVA before painting.
Doesn't matter anyway.
Cheers Richard

A binder is a glue, its what sticks the paint film together. PVA is fine before painting if the surface needs it as long as its not overdone and it soaks in - a slick surface would of course be a problem

Disagree concerning PVA before paint.

Ok boys and girls, after all the handbags and cat fights I have manages to actually get on to this problem. I have remove the cooker hood and taken some photos of both the wall and above the ceiling in the cavity. Not sure if this will shine any further light on the best way forward. or not
The photos are at:
The cavity shot is take from above the ceiling, just inside the cooker hood opening (as can be seen top left in the above photo). There is not much brick work directly above this cheek of the chimney breast, in fact its just a void. You can see some cured expanding foam which basically indicates where the ceiling meets the chimney breast cheek and has been plastered from bellow. I'm not sure if you can see a small dark patch to the left of the expanding foam at the bottom of the chimney breast cheek brick - this is almost directly above the holes drilled as seen in the previous picture. Sticking my finger in there, it does smell kinda musty, but I can see no further evidence of moisture either above or behind this area, or under the concrete lintel (left). Also, it has been raining constantly for the past two days.
Could this be residue moisture somehow trapped? If so what to do? Any ideas?

Just to be clear as well. the egress of the actual old chimney stack is on the other side to where the problem is (where the cooker hood extracts to - right, not left). The area above the void in the photo (but out of sight) is solid brick.
Ok, I cut some of the expanding foam off and plaster the area in the void with cement. I might stick some insulation up there for good measure.
I don't see what else i can do so have just scratched the plaster and filled over the top. I will try a new coat of emulsion and see how we go.
