Milk paint is a non-toxic, eco-friendly paint made from milk protein, lime, and earth pigments. It has been used for centuries and is enjoying a resurgence in popularity due to its natural ingredients. Milk paint comes in a powdered form that you mix with water before applying. With a little time and effort, you can easily make your own milk paint at home.
Gather the Necessary Ingredients
Making milk paint requires just a few simple ingredients:
Milk Protein
This provides the binder that allows milk paint to adhere to surfaces. Non-fat dry milk powder works best.
Lime
Hydrated lime is used to thicken and curdle the milk to turn it into paint. Builder’s lime or pickling lime are good options.
Pigments
Pigments give milk paint its color. You can use natural earth pigments, like iron oxides or clays, or try spices like turmeric for a yellow hue.
Water
Mix the milk paint powder with water right before use. Distilled water is best to prevent unwanted reactions.
Optional ingredients
You can also add borax, clay, or chalk to thicken milk paint or make it more matte. A few drops of essential oils can provide some scent.
Step-by-Step Instructions
Follow these steps to make your own batch of milk paint:
1. Gather Equipment
You’ll need some basic kitchen equipment:
- Mixing bowls
- Measuring cups
- Whisk or hand mixer
- Strainer
- Storage containers
Make sure all equipment is clean before starting. Glass, stainless steel, or ceramic work best.
2. Prepare the Milk Protein
Measure out 1 cup of powdered milk and place it in a bowl. Whisk in 1 cup of warm water and let sit for 5 minutes. This rehydrates the milk powder into a liquid milk protein binder.
3. Prepare the Limewash
In another bowl, mix 1/2 cup hydrated lime with 1 cup warm water. Whisk thoroughly until no clumps remain. Allow the limewash to rest for 5 minutes.
4. Combine the Ingredients
Pour the rehydrated milk into the limewash and whisk together well. Let the mixture sit for a few minutes as it thickens. Then whisk again to fully blend. This creates the milk paint base.
5. Add Pigment
Now you can add powdered pigment to achieve your desired milk paint color. Start with 1-2 teaspoons of pigment and mix well. Add more pigment until you reach the ideal shade.
Common milk paint color options include:
- Red/orange: Iron oxide
- Yellow: Turmeric or ochre clay
- Green: Chromium oxide
- Blue: Indigo or cobalt carbonate
- Brown: Umber or sienna clay
- Black: Activated charcoal
6. Adjust Consistency
If the paint is too thin, whisk in borax, clay, or chalk a 1/2 teaspoon at a time until reaching the desired thickness. For thinner paint, slowly stir in more water.
Aim for a mixture a little thicker than heavy cream. It should coat surfaces smoothly without dripping.
7. Strain Out Lumps
Pour the mixed milk paint through a strainer to remove any undissolved powder or lumps. This leaves you with smooth, lump-free paint.
8. Store for Later Use
Transfer the strained paint to a sealed container and store in the fridge for up to 5 days. Give it a quick stir before using to reincorporate any separated liquid.
And that’s it! You now have homemade milk paint ready for all kinds of craft and DIY projects.
Tips for Using Milk Paint
Here are some tips to get the best results when using your homemade milk paint:
- Test on wood first – Milk paint can react differently depending on the surface. Always do a test patch on scrap wood before painting a large project.
- Sand surfaces – Lightly sanding smooths wood grain to help the paint adhere. Be extra thorough on laminates and varnishes to degloss the surface.
- Use a primer – For problem surfaces like metal or plastic, first apply a bonding primer so the milk paint sticks better.
- Apply thin coats – Milk paint has poor adhesion when brushed on too thick. Apply multiple thin coats for best results.
- Let paint fully dry between coats – Drying time depends on humidity but can take 6-12 hours. Rushing additional coats can make paint lift or bubble.
- Sand lightly between coats – For a smooth finish, do light sanding between each coat to remove any raised texture.
- Consider a top coat – For added protection on heavily used surfaces, apply a sealing top coat like wax, polyurethane, or lacquer.
- Clean tools promptly – Milk paint dries quickly on brushes and other tools. Rinse immediately after use in hot soapy water.
With practice and these tips, you can become an expert at using homemade milk paint for gorgeous, natural-looking finishes.

Frequently Asked Questions About Milk Paint
What makes milk paint different from regular paint?
Milk paint has a very different composition compared to modern latex and oil-based paints. It contains milk protein, lime, and earth pigments rather than synthetic polymer binders and petroleum solvents. This makes milk paint non-toxic, biodegradable, and safe for the environment. The ingredients also give it unique working properties and a soft, porous finish.
Does milk paint have an odor?
Freshly mixed milk paint has a faint smell similar to limewash. Once fully dried, milk paint has barely any discernible odor, unlike conventional paint fumes. Always use milk paint in a well-ventilated area.
How durable is milk paint?
Milk paint is not as hard and durable as modern paints. It can chip or wear down over time. However, milk paint adheres extremely well to porous materials like wood and masonry. With proper prep and sealing, it can hold up to light wear on surfaces like furniture or cabinetry.
Can milk paint be used on walls?
Yes, milk paint works great on interior walls and ceilings. It provides a matte, velvety look and feel. Prepare the walls properly by repairing any defects and then apply milk paint in thin, even coats. At least two coats are recommended for good coverage and color depth.
Does milk paint come premixed?
Milk paint is sold in powdered form. This allows for longer shelf life compared to liquid paint. You must mix the powder with water according to the specific brand’s directions right before starting your project. Only mix as much as you expect to use within 5 days.
Is milk paint hard to work with?
Milk paint does behave differently than modern paints. It applies best in very thin layers. Milk paint also dries extremely fast. This means you need to work efficiently and carefully to get an even coat free of drips and brush marks. Some practice on test pieces helps build skill working with milk paint.
What’s the best way to apply milk paint?
For most surfaces, a high-quality synthetic bristle brush works best. Apply milk paint swiftly using light, thin strokes. Roller application can work but requires an extremely short nap and delicate touch. Spraying milk paint requires professional equipment. Always do test patches first when learning to apply milk paint to a new surface type.
