C-135 is All natural Milk Paint in Oyster White. The quart bag covers approximately 75 square feet. Looking to add instant character to your piece? Then look no further than Old Fashioned Milk Paint. We find that no two pieces ever come out the same with this product. Layering colors is great if you are going after that distressed look. We like to add a glaze from out local hardware store followed by a paste wax to seal it all well.
