C-142 is all natural Milk Paint in Bayberry Green. The quart bag covers approximately 75 square feet. Milk paint arrives in powder form. Just mix it with water as per the enclosed instructions. Unlike it's contemporary counterparts, it does not keep well for an extended time. We like to mix up what we need at the moment. Any leftover is stored in an air tight container and left in the fridge for a bit. Because the powder is suspended in the water, it can settle to the bottom over time. We recommend stirring it frequently.
