D.I.Y. Bodge #2. Painting (fresh ?) plaster

[Scoby_Beasley]

The front room was knocked into the hall, one wall o.k other wall 20deg fall off and ceiling well belled.
Well, I've surformed / sanded / filled / sanded / painted the ceiling, looks a treat . The fall off wall was built up with Quibble&Burgle universal plaster (white), again looks a treat .
Now the problem . The one good wall had a few dabs of filler where needed, then painted, the paints pulling off the previous three layers (bubbling / peeling so I'm gonna have to strip it.What's the best way to seal it as I take it paint isn't attached to the wall.
P.V.A/water or diluted paint or super glue (using Dulux realife and Crown suede effect).
BTW the plaster I'm hitting isn't smooth like a finish should be but it's not Browning either, more like a cement mix with sharp sand.
Quick response please before I finish me vodka and can't see straight

Better read this tomorrow as you can't see straight at the moment

Make sure the filler is 100% dry otherwise paint will bubble and won't stick to and have a look on the filler instruction if it tell you what sealer to use if any as some sealer might have a reaction to it,again read it tomorrow as it's too small writing for you at the moment

The most popular the professional use is Unibond + part water.

I think I can only see one question in your post ?

Cheers masona, the fresh paint is pulling the old stuff off i.e. a surform won't touch the plaster, need to strip and seal (the wall that is).
P.s. got a voddy left now thanks !!
