If you’ve ever travelled through the countryside in Sweden or seen photos of rural Swedish homes and out- buildings you can’t help but to have noticed the beautiful red colour used on many timber buildings.
This iconic red colour and the paint used is known as Falu Röd (Falun’ Red), named after the Swedish town of Falun, home to a large copper mining industry. The colour comes from the Hematite (Red Oxide), which is the cinder produced when the ore is heated to extract the copper. Originally discarded as waste and dumped into piles near the mine, it was noticed that a wooden post discarded with the cinders didn’t seem to be suffering from rot and decay. It was presumed that the Iron Oxide had preservative qualities and the idea of Falu Röd was born.
The exterior paint which is also known as flour paint, is made from a mixture of water, linseed oil, iron sulphate, pigment and flour. The simple method and the list of readily available ingredients, make this a great paint for DIY manufacture.

Add the Flour and cook for a 15 minutes.
Add the pigment powder and cook for a further 15 minutes mixing until the liquid is all the same texture.
Remove from the heat and add the linseed oil. Stir well to create an emulsion.
