I'm about to paint a sort of cream colour Crown paint onto a plain/sandy coloured wall covering. Obviously it's not a dark colour underneath - but what I'm worried about is do you have to do two coats to get a perfect finish? Could it look patchy with just one coat?
We managed to get away with one coat using a creamy-white Dulux paint. The colour underneath was very similar, but there were quite a few black scuff marks on the walls and even they got covered up pretty well. Just make sure you don't spread the paint too thin.
