Just wondered what you all do when plastering over gloss painted walls or ceilings? I always tend to worry about the bond between this type of paint with the plaster.
I've never liked and have never used pva over these surfaces as I just don't see there being a good enough bond between the paint surface and the plaster. I've always used thistle bond it or the knauf equivalant but wondered how everyone else would normally go about this.
Then there's scoring the surface with a stanley knife to provide a key for the plaster and with a combination of coating the wall with pva too, this would probably also do a relatively good.
So what do the rest of you guys do in this situation? :-?
