Simply mix this powder with water. It s that easy! A Milk Paint finish is unique and can range from a solid color to a stain depending on how much water you add. Milk Paint can be used on any porous surface without a primer. It will never chip or peel on porous surfaces as it soaks in and binds to the substrate. For adhesion to previously painted surfaces be sure to use the Bonding Agent. For more information visit missmustardseedsmilkpaint.com.
