I've recently had my hall walls skimmed and having waited several weeks for the plaster to dry out I went straight ahead and painted a single coat
of matt emulsion directly onto the walls.
I realise now that I should have sealed or primed the wall first. What should I do now?! Should I wait a few weeks and see how it fairs, sand it down and try sealing the walls afresh or just carry on painting and hope for the best?
