A wash finish, sometimes called pickling, is a thinned application of a latex or oil paint onto the wood. The wood grain remains visible through the finish. If applied over a solid paint, then there is a cloudy appearance to the finish. Exciting finishes can be created by painting with a dark base coat and using a thin wash in a lighter color.

Washing/Pickling: Can be done in a strong wash that is nearly a paint or a thin wash.
