An interesting idea instead of painting all the way to the top. Allowing the ceiling color to come down on the walls. @ Home Design Ideas This is perfect for spaces with lower ceilings, so that you don't make the room seem smaller and more closed off!
To paint over ANY surface, without sanding, use a product called ‘ESP Easy Surface Prep’, available at hardware and paint shops. Wipe on, wipe off and paint in 90 minutes. Works well over enamel paint , without having to sand. In case we buy an ugly kitchen.
