How To Make Flour Paint Recipe
- In a large metal recipient, bring 7 liters (7 qt) of water to a boil.
- At the same time, mix the flour in 1 liter of water (1.5 qt). Pour the mix in the boiling water and let cook for 15 minutes while stirring.
- Add the coloring pigments as well as the Iron Sulfate, and keep stirring for 15 minutes.
- Add the double boiled Linseed Oil, and stir for another 15 minutes.
- Add the liquid soap, stir, remove from the heat source and let the mix cool down.

It is recommended that you do not paint in the heat or direct sun. After applying your first coat, you should wait 24 hours before applying your final coat. It is also suggested that 2 years later you top up your paint. This will result in extending your paint for a further decade. It is also suggested that you do a test patch on the area you intend to paint to check results.
