Usually if it's silk it's got a shiny surface and I usually score it with a wallpaper scorer or even a Stanley knife is it hard plaster or plaster board behind

Strange any sign of damp is it an outside wall I mean like a wall that faces the outside of the building

the paint as not keyed to the background. the emulsion was either applied to lime wash, distemper. or the paint was applied without a colour wash, i.e. to thick .
how large an area has not keyed ?

Check if it's peeling off if not let first coat pull In nicely then second coat. Nothing like a nice long hit in the evening.

On backgrounds that could cause problems i have a hand wood saw. I have removed handle and cut blade in half. Drag across surface to break back to background. It scratches lines back to good surface. Seal then skim.


this has happened to me before but just let the first coat go off then top it out as normal :D

Not had a wall come off due to it :D
