All natural Old Fashioned Milk Paint in Bayberry Green. The pint bag covers approximately 35 square feet. Milk paint arrives in powder form and consists primarily of milk powder, lime and pigment. 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 so it needs stirred frequently.
