I've just had a room boarded and skimmed. The first two coats I used "No Nonsense Trade Bare Plaster Paint Brilliant White" and applied it with a wooster pro doo z roller. https://www.screwfix.com/p/wooster-pro-doo-z-roller-sleeve-polyester-pile-9-x-70mm/5274x I didn't realise but the roller has a 1/2" nap I've since reduced to a 3/8" pro doo z roller. It's had 3 coats of Valspar v300 Rocky Mountain Mist (R205E) and it has a "orange peel" effect. The texture is so porous that it has a shadow so it looks even darker in places. You can also see lines where I've rolled, presumably too thin. Weirdly the colour has turned out blue, nothing like the gray it's meant to be. I've been laying off in the same direction, working away from the wet edge. Whats the best way of fixing this? If I sand the wall, do I need to seal it? The paint dries extremely quick but I've now used 15ltrs of colour paint (standard 4 walls, bay window 1930's semi detached house). I never watered down the No Nonsens Bare Plaster paint, was that the mistake?
