I'm busy painting plastered walls at the moment, using a bespoke (off-white) vinyl silk emulsion. There are some wooden battens on some of the walls which I want to paint to be as 'invisible' as possible, ideally using the same emulsion. I know that's not the kosher way to do it, but will that work reasonably OK? How best to prepare the wood - primer/undercoat first as for gloss, or not; something else?
