Thanks for this. It looks good

Thank you very much for the video. Except for the boiled linseed oil, is non-toxic. The boiled linseed oil that you get at the hardware store has metallic salts in it to speed up the drying (polymerizing) process. Unfortunately these salts are toxic. I wouldn't use the tools again for food grade purposes. There is a way to use raw linseed oil though, you have to polymerize it several days out in the sun, covered with glass; but that is a whole topic by itself. I read that if you use rye flour produces an even stronger paint.

Good point! The boiled stuff isn't food safe. Thanks for watching. I'll have to try the rye flour next time.

Rye flour is definitely preferred, as wheat flour increases the risk of the paint moulding quite significantly... Go for stone milled, fine rye flour if available. The stone milled flour has longer fibers (as compared to steel cut flour), which helps the paint stick better. (You want a flour with some gluten, but not too much gluten, if that makes sense. Rye is perfect.) Also: you don't need to add linseed oil to the paint. Most original recipes don't contain any linseed oil whatsoever. The linseed oil makes quite a big change to the properties of the paint. It might make the upkeep more labor intensive, alter the hue of the paint etc. TL;DR don't use wheat flour if you can avoid it, use linseed if it fits your needs.

Cutest. Man. Ever. 😦

Thank you so much for sharing this! Would this paint work in other surfaces besides wood, such as asphalt, concrete, plastic, and resin panels?

Hey, great video in general! It's very nice to see that our traditional paints have something to offer outside of a Scandinavian context. Just one thing: would you please consider adding a note about the type of flour that should be used? The resource you've linked mentions wheat flour - which isn't at all what have been used traditionally. Wheat flour contains too much gluten (and nutrition), which increases the risk of mold. Fine stone milled rye flour is really the way to go if you want a long lasting and durable paint. It contains just enough gluten for the paint to stick, but not enough for it to start molding. The stone milling part is important too, as modern milling techniques cut the fibers shorter (which makes the paint less durable). I understand that some people might not have access to the right kind of rye flour, but they should at least be aware of the potential risks associated with using wheat. And one last thing: this paint could be made with any earth pigment. You could use yellow ochre, or whatever is available in your local area. (Use zinc sulphate for light pigments and iron sulphate for dark pigments.)

Thanks so much! That's great information and doesn't surprise me. Wheat would have been more expensive and coveted than rye anyway, so it makes a natural choice. I grow and grind different grains here, including wheat and rye and will give the rye a go next time. Thanks for watching!

@@bodo9387 Some people use Boracol, which I think is Borax. If using Boracol, something like 100 milliliter Boracol to 10 litres of paint could work. I personally wouldn't use it, as it is quite toxic, but if it's used, it should be added after you've removed the paint from the heat. To add to this: it seems like there is a connection between the addition of linseed oil and the occurrence of mold. As in no linseed oil - less mold. However, adding (boiled) linseed oil makes the paint a little bit more weather resistant. But it also gets harder to remove it once it's time to repaint the house. (If you're adding linseed oil, you have to add soap as an emulsifier. We use something called brunsåpa/kristallsåpa, grönsåpa or gulsåpa. These soaps have a pH of 9.5-11 or so. Max 8% linseed oil and no more than 2% soap.) Mold spots etc is more of a problem with lighter colours, but it also depends on where you live.

@@bodo9387 Perhaps that was the original thought, but it doesn't seem to have any remarkable antifungal properties. This being said, it is one of the ingredients that's included in the "core" recipe for this paint, along with flour and the pigments. It probably shouldn't be omitted (unless making lighter paint, as mentioned in my original comment). In the olden days, different painters added different ingredients, depending on local customs and personal preference. Some of these included resin, urine, salt water that had been used to preserve herring, wood tar, and many more. This means that there are multiple ways of making this paint. (And some versions probably work better than others.)

Is this how they made linseed oil paint 1,000 year ago? I was surprised that is had more water than anything else in it.

How's it holding up?

Awesome info!!! Generally speaking, how long would this last on exterior siding/fence/barn before it starts looking worn? I need to protect a TON of cedar siding and I'm considering this linseed paint method.

It really depends on the cedar... Generally speaking, it is advisable to leave the wood as is for a year. In Swedish, we say that it rises. Idk the English equivalent, but the point of it is that the paint will stick better once the wood has risen. Otherwise it might crack when the wood starts to dry out. You also need to consider whether or not the wood has been planed. Flour paint (also known as sludge paint) works best for surfaces that have not been planed. (For planed surfaces, we traditionally use linseed oil paint, which is better suited for the material.) If it's too hot when you're painting, the paint won't penetrate the wood, which means that it won't stick properly. (You also don't want it to be freezing.) Adjust your painting plans to the local climate. Bonus: if you use fine, stone milled rye flour, your paint will last longer than if you use wheat flour. New wood that hasn't been painted before usually needs two coats of paint. Perhaps three. Make sure that each layer dries up completely before adding the next. (This is very important.) The first time you paint a surface, it will last for 5-7 years. Then you repaint it. From that point on, you only need to repaint the surface every 10-15 years (unless you live next to the ocean/in very harsh climate). The repainting procedure goes like this: Brush the old paint down using a scrubber brush (or similar). Be thorough. Rinse the walls (use your garden hose, DO NOT use high pressure). Ideally, you want to start painting before the walls dry up completely. The paint will stick better if the walls are a little bit damp. One coat of paint is usually enough, but south facing surfaces might need two.

@@wd8005 From what I know, pine was preferred. Nowadays, people use spruce a lot. But the paint probably works on (some) other types of wood as well. Generally speaking, the flour paint was high status initially (17-18th century), and then gradually spread to lower class houses as time progressed and the pigment became more affordable. Which explains why it wasn't used on fancy materials like imported wood and similar.

Oh, good question. You'll have to google for that. If you can find a powdered black mineral or earth pigment that will work in paint, you can swap it out for the "iron oxide" in the above recipe. Or maybe experiment if you have the time. I wonder if powdered charcoal would work or if it would smear and rub off?

@@LowTechInstitute If you want something that looks like flour paint but doesn't rub off as readily, you could add more linseed oil to the paint. This would transform it into a sort of hybrid paint, but it will still have the same matte finish as flour paint. Black iron oxide should certainly work for flour paint. Idk about wooden charcoal, but I know that people have burned bones and used the charcoal in other types of paint. Soot (from wood fire) has also been used in linseed oil paints and lime wash (kimrök - carbon black), but I've never tried it in flour paint. Can't see why it shouldn't work though...
