Milk paint, or casein paint, is a mixture of quark, water, pigment and baking soda or lime. Milk paint contains only natural ingredients and is 100% biodegradable, odorless, safe and contains no solvents, preservatives or other additives.

Milk Paint is ideal for decorative paint effects such as old or washed looks on furniture. The coating is not entirely waterproof, so for surfaces that are used extensively or outdoors it is sensible to seal the paint. This can be done with a varnish, oil or wax. Milk paint is easy to make at home, there are various recipes to be found online.
