Home Improvement Stores
Most home improvement stores now carry organic, eco-friendly paint products, including milk paint. Ask if your local chain store either carries or is able to order milk paint.
Many hardware stores also sell milk paint. Visit the paint and wood stain section of your local store, or call ahead to check availability. Most hardware stores have a catalog you can browse and order from if the store does not have what you're looking for on hand. The item can either be shipped to the store or to your home.
Woodcraft Supply Stores
As milk paint is used on many wood crafts such as doors, trims, etc., most woodcraft supply stores also carry the paint in a variety of colors.
Many antique shops also sell milk paint, as it is known to be associated with older decor and is perfect for restoring antique furniture and other projects.
Online retailers carry milk paint in a variety of colors. These retailers allow you to shop their selection, request free samples and browse a list of dealers near you. You can avoid shipping costs if you have your item shipped to a dealer.
