When painting Milk Paint by Fusion over raw bare wood, you need to do very little to no prep at all! The beauty of milk paint on a wood surface is that you still see and feel the wood grain. This is completely unique to anything else out there in the paint world. Don’t worry, you'll still get full opaque coverage over the wood, with a solid colour, as often many think that Milk Paint is more like a stain. It can actually be anything you want it to be by controlling how much water to powder ratio you add.
