Interior walls and ceilings
New plaster is left to dry, then given a thinned mist coat so the first proper coat has something to key to, followed by the specified finish coats. On existing walls, previous coatings are checked for soundness, unstable or contaminated areas are removed, cracks are cut out, filled in build-ups and sanded flush, and stains are blocked with the appropriate primer rather than covered and hoped for. Finishes are chosen for the room, washable and moisture-resistant products in kitchens, bathrooms and utility rooms, standard emulsions elsewhere.
