I have recently had a plaster repair job completed, and having left it to dry out for a few weeks, applied some Farrow and Ball paint to the surface. Two coats in with a roller and the paint appears to have cracked as it has dried, flaking away from the wall surface.
This is only in a couple of small patches, not the whole area.
I anticipated that the surface might be a bit more porous and need more paint - but what is the advice to get an even finish across this surface?
Thanks in advance for the experience and expertise!
