Wheat glue is present in the recipes of paints and coatings of earth or clay from all continents. Together with rice, casein and bone glue, wheat flour is one of the materials used by the crafts of healthy habitat for a long time. VOC-free, solvent-free, Swedish paint (also called "flour paint" or "ochre paint") will protect both wood and industrial paints.
You will find in this kit the necessary ingredients to paint 15 m².
Les ingredients :
► The flour : it acts as glue
► The pigment : it brings not only the colour but also the charge, for a smooth paint
► Iron sulphate : anti-harmful substances
► Linseed oil : essential protection of the wood
► Black soap : it texture the paint and brings a friendly smell of olive oil
► Water : neutral element that will give the fluidity
Material required :
► A saucepan or pot going on the fire that you will use only for this purpose
► A wooden spatula
► Latex gloves for handling iron sulphate
► An airtight container for the preservation of your paint
►Bring 2.8 litres of water to a boil
► Mix the flour in 400 ml of cold water and add to the 2.8 liters of hot water. Stir, then cook over low heat for 15 minutes.
► Add the pigment, iron sulphate pot. Cook for another 15 minutes, stirring. Depending on the pigment, the mixture may become too thick : add 100 ml of water.
► Stir in flaxseed oil and cook an additional 15 minutes.
► Add the black soap jar and stir out of the heat.
► Let your paint cool and adjust viscosity by adding water. Your paint must be creamy to be well-covering.
► Transfer to an airtight container.
Your paint is ready. It has a very strong covering power but for a better hold in time, we advise you to apply a second layer the following year.
This preparation, which contains no preservatives, is kept only 3 to 4 days in the refrigerator in an airtight container.
The paint is recommanded for raw spruce and Scots pine lumber. Tannin-rich woods and exotic woods may reveal brown spots.
Precaution of use :
Iron sulphate should be handled with gloves and stored out of the reach of children. We advise you to use a mask as a precautionary principle.
Information to know :
The final colour will be a little darker than the colour of the pigment, because of the mixture with the linseed oil which darkens the tint.
The natural pigments (yellow ochre, red ochre) are indestructible to UV. Not all pigments are compatible with the recipe of flour paint.
Linseed oil and flour are unfit for consumption. The smell of this paint is very pleasant (omega 3 present in linseed oil).
The carton, the PET jars are recyclable in the yellow container and the glass jar in the green container without the cap.
