THE OLD FASHIONED MILK PAINT CO. Milk Paint comes in powdered form and is made from casein (milk protein) mixed with lime, clay, and earth pigments. Water is added to make a pint, quart, or gallon size. It is available in 20 historical colors, which can be blended or tinted. Original Milk Paint is marketed primarily as a paint for wood furniture or other porous surfaces, but the company's SafePaint can be used on walls. While not third-party certified, these paints could qualify for LEED for Homes MR 2 Credit. 978.448.6336. www.milkpaint.com
