Anyone have any experience of this 'acclaimed' product? I'm looking to
apply it to a wall that has A: old, sound plaster B: paint over old,
sound plaster C: gypsum skim-coat ( feathered )over paint over old,
sound plaster.

Should I sell the house instead?

And what was wrong with the reply I made to your previous post on this a
day or two ago?

Thanks for your previous suggestion, Chris. My continuing concern is
that the 'old paint' adheres to the underlying plaster with varying
grip. Just when I think I've removed the areas that have weak grip,
then sand down and wipe over with meths, some more curls and shows
loose, so I remove that, too. It's not desirable to remove all the
existing paint - if this can be avoided.

On another couple of areas in the house, I did as you had previously
suggested - diluted emulsion onto new but dry, feathered skim-coat. Let
dry a couple of days, then a first top coat. Problems of bubbling
emerged in several places.

I'm trying to avoid having that again, by the possible use of this
Zinsser product *under and over* the new skim-coat on my firebreast.

Well continuing in that thread might have been more helpful, rather than
appearing to not received it.

I can't see that any primer, or anything else is really going to solve
this - it's still going to have poor adherence to the plaster. I
assumed by your description that the paint layer was sound. I think he
only way it to sand it down or lining paper.

Well I did pretty much a whole house and never had problem (and it's
what is recommend on backs of Dulux paint). Thoughts - was the paint not
dilute enough maybe and didn't soak into the plaster enough then trhe
paint film might not adhere enough. If it doesn't go on easy - if the
brush seems to stick to the 'plaster' then the paint is too thick

I'm trying to avoid having that again, by the possible use of this

good luck :-)
