I've bought a home built sometime in the 1960's. The kitchen has two sets of cabinets. They have all been varnished an ugly darker color, however, on one side of the kitchen the varnish has been painted over. I would like to repaint all of it, to make it match and brighten up a very small, dark kitchen. I'm clueless as to how to begin. Could someone tell me how best to tackle this project? Will I need to remove or treat the painted and varnished surfaces before I can do anything to it? Money is a bit of an object, otherwise I would just tear them out and start over. Thanks in advance for your suggestions.
