How to make Nordic Red Paint or Falu Red
(makes 10 litres of paint):
8 l water
0,6 kg iron sulfate
0,8 kg rye or wheat flour
1,6 kg earth pigment such as red iron oxide

Add the iron sulfate into hot water. Mix in the flour and cook the mixture until it thickens. Add the pigment gradually, stirring all the time. Finally pour in the boiled linseed oil and cook for another 2-3 hours.
We do not take responsibility for the quality of home made paints. If you are in doubt, we recommend purchasing ready made paint.
Iron sulfate treatment cannot be made on surfaces that have previously been painted, impregnated or oiled. It is suited to clean, untreated wood only.
Since iron sulfate is not a ready made product or surface treatment agent, we do not take responsibility for the results of the use of iron sulfate. If in doubt, we recommend using our paints or other surface treatment products instead.
