What is the difference between chalk paint and milk paint?

Chalk paint is a modern acrylic product with a matte finish that adheres without prep. Milk paint is an all-natural powder mixed with water that creates a more authentically vintage, sometimes chippy finish.

How do I prevent milk paint from chipping?

Add a bonding agent to the mix when painting smooth or previously finished surfaces. On raw wood, milk paint bonds naturally without chipping. The chipping effect is desired for some vintage finishes.

Milk paint is one of the oldest paint formulations, made from natural ingredients including casein (milk protein), lime, and earth pigments. It creates an authentic, slightly chippy vintage finish that cannot be replicated with modern paints. Available as a powder that is mixed with water, it is completely non-toxic with zero VOCs, making it safe for children's furniture.
