What is Milk Paint?


Milk paint is an environmentally-friendly water-based paint that is sourced from 100% organic materials. The paint is non-toxic and biodegradable. Milk paint dries faster than oil paints. It dries within 30 minutes in contrast with 24 hours required for oil paints to get dried. Milk paints mostly exist in powder form; you only need to mix with water to form liquid paint.

The organic ingredients contact casein, which works as a binder; lime, which makes the paint durable and hard; and natural earth or mineral pigment, which gives it color. In some recipes, borax is combined with milk’s casein protein to activate the casein and act as a preservative.

[LIST B](For solid opaque look: combine water and milk paint in the ratio of 1:1. Mixed milk paint should have the consistency of table cream for opaque coverage. When you are satisfied with the texture, use a little sample to see if you have gotten to the required thickness. The brush drags show that the mixture is opaque or too thick, and you need to add more water. If the paint is transparent and drips, you need to add more powder. You need to adjust as required and begin to paint.)

  • For a stain/wash: Combine three parts of water to one aspect of Milk paint powder. Any color is useful for making a stain. Put water in the container first, add powder and steer with a spoon, whisk, an electric milk frother, or blender. You can use a blender for better results.
