Can I paint my kitchen cabinets without sanding?
If you are painting cabinets that have never been installed or varnished. Yes. But if there is any sigh of food, oil from your hands, build up if grease near pulls and corners etc... you need to completely remove it. If you don’t... paint will chip or peel the moment you clean or hit those areas.
Products like degreasers or TSP never work for older cabinets. If they actually worked we would be millionaires.
