Milk Paint is an ancient natural paint containing basic ingredients including milk protein (casein), limestone, clay and pigments. When absorbed into the surface, Milk Paint will never chip or peel. It is suitable for both interior and exterior applications and is naturally mold resistant. Milk paint provides a completely breathable coating and is ideal for painting wood, plaster, drywall and a variety of other surfaces. It is environmentally friendly (non-toxic, no VOCs). Milk Paint comes in powder form.
