Casein or Milk paints have a long history of use, particularly in America. They are hard-wearing, inexpensive, easy to make paints that provide a perfect base for pigments. By mixing milk protein or casein with an alkali, a strong binder is produced that adheres itself and pigments to the surface it is painted on. Milk paints are an important addition to any nontoxic, VOC free household for walls, woodwork and more. They produce a flat, matte finish. Like lime coatings their look can be further enhanced by topcoats such as oil or wax. Versatile in effects, milk paint is also used widely in faux finishing techniques such as washes, sponging, ragging, etc. and is highly favored for artist and craft work.
