Milk PaintKitchenEasySafety: High Risk
Old-Fashioned Milk Paint
The classic American farmhouse paint — simple, breathable, biodegradable.
Color
Any pigment — chalky, matte
Binder
Skim milk + lime
Mix milk, lime, and pigment. Brush onto wood and let it cure.
- ▸Lime turns the milk into a tough, breathable coating.
- ▸Looks chalky and ages beautifully — never plastic-looking.
- ▸Comes off easily if you don't seal it, so it's good for restorable furniture.
Steps
- 01
Mix lime and milk into a smooth slurry — it will fizz slightly.
- 02
Stir in pigment until you have the color you want.
- 03
Add a little water if too thick.
- 04
Brush onto raw wood within 8 hours — it spoils overnight.
Materials4
- — 1 cup skim milk
