Hi Just had my living room skimmed with new plaster. When the plaster was dry I painted it with Johnsons premium contract brilliant white ( supposedly perfect for new plaster). Looked great but the finish was too bright and hurtful for my wifes eyesight. Over painted it Dulux brilliant white (Matt) Walls are patchy now, I believe sometimes called paint flashing. Any advice on how to overcome this so that it looks smooth.Ta
