Milk Paint - How Cool Is That!
I immediately made plans to make some and test it out. However I lacked some of the material and the plans were put on hold until I had gotten hold of them.
I ended up ordering some stuff from Kramer pigments in Germany (they apparently also have a shop in the US), but never really did anything with it. But the other day I got an excuse to start that process again and made some paint.
I want to refinish some dining chairs that I got for little money in a thrift store. I have plucked away the old and ugly fabric that covers them and am working on sanding the frames. I want to paint them with milk paint in an ivory or creamy colour and upholster them in linen. I have a thing for linen these days.
Milk paint is made from milk, lime and pigment, sometimes with the addition of Borax. The Borax helps the lime dissolve the casein protein in the milk so it makes for a smoother paint as well as provide some preservative qualities to it. But milk paint spoils easily so it should be used within a few days once it is mixed. Store it in the fridge in between uses, but let it reach room temperature before painting with it.
Milk paint adheres well to fresh wood and will give a strong and durable finish. It is a very good alternative to the plastic water based paints that are available.
For this recipe use 1 liter non-fat milk, ½ cup vinegar. 1 tsp borax and 1 cup of lime putty.
To make the glaze, make the curds as above, but do not add borax or lime. Instead drizzle linseed oil into the glaze as you use the stick blender to mix. Add pigment if you wish to tone the glaze. The pigment always needs to be slaked, which means: Measure equal amounts of water and pigment and let sit for an hour. Use this to glaze over the paint. Let dry.
