This month we are going to paint the inside of the old girl, our lovely straw bale office that we built together. The paint is made from flour and water. How ecologically safe is that! And cheap! It does have some kaolin powder that is white clay powder, to help with the colour. I bought a kilo for about £4 off the internet. You can use any coloured clay powder you like as natural pigment.
This paint will not last as long as oil based paint but is easy and cheap to make and brushes on almost like any ordinary paint. When dry, it does not brush off when you rub against it. It does not smell or attract insects as paints made with milk products can do.
Take a cup full of wheat flour. I used the cheapest flour I could find.
Mix the cup of wheat flour and 2 cups water with a whisk in a bowl.
Remove ALL lumps!
In a large pot, boil 1 1/2 cups of water. When the water reaches the boiling point, add the lump-free flour water.
Turn down the heat and stir constantly until the mixture becomes a thick paste. Remove from the heat. Gradually add 2 cups of water, stirring to dilute the paste.
It can be thick so use old brushes. We are painting on cob so any impurities and brush strokes that show don’t matter. You can sponge down a second coat once it begins to dry, to remove brush strokes if you like.
Good luck! Let us know how you get on.
