A stain on a room ceiling is an eyesore that’s hard to miss, but painting products used by the pros can conceal just about any kind of stain. Before repainting the ceiling use an oil base sealer and primer like KILZ to block the stain and it will disappear. To make ceiling painting near goofproof, and to avoid missed spots when applying white paint over an already-white ceiling, try a ceiling paint with color-changing technology that goes on pink (Glidden) or violet (Dutch Boy) but dries to a white finish. Normally, it’s difficult to see start and stop points, and you often miss some spots that have to be recoated. These products, however, guarantee that you won’t have any glaring mistakes.
To prime and paint a stained 15-by-20-foot ceiling a painting contractor will charge $375, which includes the labor and material. You can buy the primer and paint for $62 and do it yourself, and save 84 percent. You’ll need to remove most of the furniture and protect the floor with drop cloths. The equipment is a paint brush to outline the joint at the wall and ceiling, and a paint pan and roller with an extension handle to apply the paint on the ceiling. You’ll probably also need a step ladder. Before you begin, get rid of any dust, especially in the corners, and wash the ceiling and molding with a household cleaner if it’s dirty. Avoid any mishaps that might happen using a gallon of paint by pouring some paint in a small container - like a coffee can or a paper or plastic paint pail - and carry it up the ladder. It’ll fit more easily on the ladder tray and be easier for you to handle. Even if you do tip over the paint, you’ll have less to clean up.
