Milk paint is a non-toxic, odorless, and water-based paint with low volatile organic compounds. It is made up of milk protein (casein), lime (calcium carbonate), clay, and natural pigments. Unlike chalk paint, it is sold in a powder form and mixed with water before use. Milk paint is an eco-friendly paint as it does not contain polymer binders, additives, and synthetic products. It was first formulated about 49,000 years ago from bovid milk and ochre mixture in a South African cave. Later, acrylic gained popularity and replaced this paint. Now it is revived for its biodegradable qualities among DIYers and sustainable designers. Unlike latex or acrylic paints, milk paint does not emit strong fumes, making it safer for indoor projects. This matte paint is available in 56 colors, ranging from classic neutrals to bold reds, blues, and greens.
