Milk paint has roots set firmly in the past, as some of the first human cave paintings used a similar concoction. Its main ingredients include milk (or quark) and lime, and it mostly comes in powder form, requiring it to be mixed with water prior to use. It has a slight sheen, and the solution’s color can be altered by combining colored, dry pigments into the base paint.

Milk paint is one of the most environmentally-friendly forms of paint, as it is water-based, non-toxic, and free of volatile organic compounds (VOCs).

What do you use milk paint for?

Milk paint can be used on a variety of surfaces, including walls, ceilings, furniture, and decorative objects such as vases and jars. As the name suggests, it has a “milky” appearance, making it perfect for a paint wash, for thinning out other paint, or for achieving a rustic style.

There’s no doubt you have seen milk paint finishes on platforms like Pinterest, as many DIY lovers use milk paint to achieve an antique-inspired, ‘chippy’ look. This is achieved by sanding the milk painted surface once dry.

2. General Finishes Milk Paint: This is a modern, pre-mixed liquid paint that has an acrylic base, so although it’s not a ‘true’ milk paint, the product imitates the low luster of traditional casein-based milk paint.

What is chalk paint?

Traditional chalk paint dates back to 1990 when British artist, color expert, and author Annie Sloan first developed the mixture. Chalk paint has a matte chalky texture, but unlike most milk paint, it comes in liquid form and is ready to apply. It’s completely odor-free and takes just one hour or less to dry completely.

This type of paint is also much thicker than milk paint, requiring fewer coats for an even finish. To create a unique color, one chalk paint must be mixed with another chalk paint.

What do you use chalk paint for?

Just like milk paint, chalk paint can be applied to walls, ceilings, furniture, or décor items. But due to its thick consistency, it can prevent underlying textures from showing through. You can give the surface a matte appearance or distress the paint for a “shabby-chic” vibe.

On Pinterest, you’ll notice the majority of painters like to use chalk paint for making over their stained furniture, such as chests of drawers, coffee tables, and kitchen cabinets.

Chalk paint pros and cons

Which is better — milk paint or chalk paint?

The choice of milk paint versus chalk paint depends on the desired effect you wish to achieve. It also depends on the color you want to produce. Milk paint works better as a paint wash.  It’s also good for thinning out other paint, or for achieving a rustic, ‘chippy’ style with a very light sheen. And don’t forget: you can mix milk paint pigments to create any shade you want.

Chalk paint, on the other hand, is better for creating a thicker, more even finish with a completely matte appearance. It can also create a realistic antique look when distressed, however, color options and color mixing is more limited.

Frequently Asked Questions

Can milk paint be used over chalk paint?

Why would you use milk paint?

Milk paint distresses much more easily than other types of paint, making it a simple and ideal way to achieve a vintage-inspired ‘farmhouse look’ with furniture.
