Sorry if this is in the wrong thread. I'm new to the forum and don't usually use them. Paint is flaking of my plaster. Let the plaster dry for 8-9 months, done a mist coat and then painted. It's remained on the other 3 walls in the room and this is an outside wall where the bath used to be.

If the plaster was too smooth and shined up by the plasterer then that can effect the paints adhesion, or there could be contaminated spots caused by something splashing onto the surface maybe

Do I just need to sand these areas down further in the hope it sticks?

A light sanding with a light sand paper could help
What about if that doesn't work? This isn't the first time it's happened, think this will be my second time lol. I was thinking sealant paint which has been suggested a few times also.

Horrible when this happens as when you try to sand the edges to feather the paint out, it’s just keeps peeling off and before you know it, you’re chasing the lot off.

If it’s just a few patches and the paint is generally ‘stuck’ then carefully sand the edges, put a bit of Zinsser bin on it and when dry, skim of filler, sand, Zinsser then paint away.

I usually give fresh plaster a quick flick over with the poke sander, wipe the dust off with a damp rag then mist coat.

Was you on grand designs and having a baby?

..you’ll have a breakdown next then your Mrs will leave you and Kevin McCloud will come round and laugh in your face cos you went over budget by 200%

We were just looking at the zinnser last night, think this may be the next bet. You're spot on about the sanding and it continuing to peel sightly lol.

So I've bought the zinsser, and applied it. I then put a skim of filler on it e.g polyfill? Once i sand that down I reapply the zinsser, do I then use a coat of emulsion on that then once dried use the final paint for the last coat i.e. vinyl?

just cover the repair with Zinsser and paint with your finish. If you haven’t bought filler yet, get some Toupret as it feathers out really finely.

Good news... for the most part this worked. Was putting on my final coat and another bit bubbled. Luckily not a spot where I'd put filler. Otherwise you'd hear about a man on a rampage and the reason being painting plaster

Good result then. It’s these kind of piddly jobs that really pee my off as they usually happen just when you think you’ve nearly finished a job.
