Milk paint is a non-toxic, odorless, and water-based paint with low volatile organic compounds. It is made up of milk protein (casein), lime (calcium carbonate), clay, and natural pigments. Unlike chalk paint, it is sold in a powder form and mixed with water before use. Milk paint is an eco-friendly paint as it does not contain polymer binders, additives, and synthetic products. It was first formulated about 49,000 years ago from bovid milk and ochre mixture in a South African cave. Later, acrylic gained popularity and replaced this paint. Now it is revived for its biodegradable qualities among DIYers and sustainable designers. Unlike latex or acrylic paints, milk paint does not emit strong fumes, making it safer for indoor projects. This matte paint is available in 56 colors, ranging from classic neutrals to bold reds, blues, and greens.

What are the Uses of Milk Paint
Here are the four common uses of milk paint:
- Furniture: Milk paint is used to paint dressers, tables, cabinets, hutches, and chairs for a weathered finish. It increases the lifespan of wooden trims, headboards, and bed frames. Milk paint provides a rustic and aged look to bookshelves and wardrobes.
- Walls and Ceilings: Milk paint is suitable for textured or plastered walls in vintage homes. It’s a breathable paint that doesn’t trap moisture. It reduces the peeling paint and provides a chalky finish. Milk paint is also used to add patterns on ceilings and accent walls.
- Decor and Crafts: Milk paint works well on picture frames, boxes, trays, and jewelry boxes due to its quick drying properties. It is also used on handmade ornaments, plant pots, and vases to add intricate designs. Milk paint is used to paint decorative tiles, cardboard crafts, and papier-mache models.
- Restoration Projects: Milk paint is also used to restore historical furniture with a shabby chic character. It doesn’t require heavy sanding and provides a smooth finish. Homeowners prioritize milk paint to restore their antique dressers, cabinets, farmhouse tables, and wooden beams.
How to Apply Milk Paint
Here is the step-by-step guide to apply milk paint:
- Surface Prep: Clean the surface with a slightly wet cloth to remove all the debris and dust. Use sandpaper to rub the glossy surfaces, as milk paint doesn’t stick well to it. Use a primer only for the first coat to promote adhesion.
- Mixing: Mix the dry powder and water in a 1:1 ratio to prepare the milk paint mixture. Stir thoroughly and let it sit overnight or for a few hours. Add anti-foaming agents to reduce bubbles and adjust the water-powder ratio to achieve ideal consistency.
- Application Tools: Use a brush to add patterns and a roller for a uniform coverage with a matte finish. Prefer an airbrush or sprayer for easier blending and to save your time. Apply two coats of different colors and then sand roughly for a two-tone distressed look.
- Sealing: Sealing with wax (clear, tinted) and oil (linseed oil, resin) is important to enhance its durability. It also makes it water and stain resistant.
What are the Limitations of Milk Paint
Here are the six limitations of milk paint:
- Needs bonding for slick surfaces: Unlike acrylic paints, milk paint doesn’t contain strong synthetic polymer binders. It requires bonding agents (acrylic-based) for proper adhesion on glossy surfaces.
- Short mixed shelf life: Apply paint quickly after mixing it with water. Milk paint contains real milk protein (casein) as a binder, which spoils within two days due to bacterial attack.
- Chips easily or intentionally: Milk paint chips or peels due to its weak bonding and powdery texture. It is only used to give a worn-out and aged look to furniture.
- Sealing often required: Milk paint absorbs moisture without a topcoat, which leads to frequent repainting. Sealing reduces the moisture buildup and protects it from wear and tear.
- Less vibrant colors: Milk paint only has muted and earthy tones, making it unfit for neon and shiny looks.
- Needs multiple bold coats: A single coat often leaves the base material visible. Milk paint has a watery consistency and requires 2 to 3 coats for proper coverage.
