Milk paint is a natural paint that relies on the natural milk proteins generated by the curdling process, which is the same as what occurs when making cheese. This type of paint offers a long-lasting, beautiful, matte finish for our homes' interior and exterior. For homeowners wanting to experiment with their own milk paint, take a gallon of skim milk out of the refrigerator and let it warm to room temperature. Then, mix one quart of milk with a half cup of white vinegar to start the natural curdling process. Within an hour, you should see the milk solids (or curds) rising to the top of the bowl. Cover the milk and vinegar bowl in a warm place in a kitchen for 1 to 2 days to let the milk finish curdling.

Is Milk Paint Environmentally Friendly?

Milk paint offers several benefits both for our health and for the natural environment. When combined with natural, earthen, or mineral pigment powders, such as those offered by Earth Pigments , milk paint will have absolutely zero VOCs. Furthermore, whereas even the greenest commercial paints will contain additives and distillates that can cause several negative environmental effects, milk paint will cause absolutely no environmental harm. It can be much more safely disposed of as well.
