What size Lime Wash paint to buy for standard 8×12 ft wall? After reading a couple of posts recommending a variety of lime wash paint types, I’m gonna go with Bauwerk. I have a very simple white wall (previously painted, smooth) in my dining area that’s 8×12 feet roughly. Those who have worked with lime wash and of course added the water, what size paint would you recommend? It’s sold by litres. Thanks …
