Simple question, I think! I want to use dob and dab to put up some
plasterboard on a brick wall. The only problem is that the wall has
been previously painted. Can anyone tell me if this will be a
problem, and if so, suggest what I might do about it. Many thanks.

never saw the original post..odd.

it could be a problem depending on what you are dabbing with as it were.

I'd check a dab first and see if it rips off.

Mind you, it doesn't take a lot to hold platserboard up.

cut/scratch roughly through it into whatever's underneath - with a
stanley knife - where your dabs will be.

Your original post never made it to the group, probably Google again.

Firstly, it's dot and dab, and I shouldn't imagine the paint will affect the
adhesive, but you can scratch it off in patches if you like, certainly
wouldn't do any harm, but you don't need to go to town on it

The dot-n-dab adhesive may key into the paint, but probably not
through it.

Thus the strength of the bond depends on that of the existing paint to
brick, which is usually very strong. A guide is you stick sellotape to
it, leave it a while and pull it off - if paint comes with it then
scratch through the paint to brick.

If the wall is external you could use insulation backed plasterboard
to improve comfort and reduce energy bills. Just worth mentioning,
even if it has cavity insulation adding 25mm Celotex backed
plasterboard will still improve comfort & re-heat time.
