i know this has been covered before and i know theres no need for pva! i'm going to get some wickes trade paint for new plaster to paint a newly skimmed ceiling, its gone the light colour after best part of a week.
my quick question is this, is there any need to do anything to the new smooth plaster? eg sand it, wipe with a damp cloth? i notice when wiping i sometimes get a plaster colour stain on the cloth, so it must be removing some dust or something. or will the paint just hide this?
