PEP BB naturalbuilding.sand.claypaint - Make Clay Paint

I finished my she shed walls and now needed to paint them! Hehe! Trouble is, I was 6 months pregnant and didn't want to breathe in any toxic fumes, so I have been experimenting with different painting methods. I textured my walls with plain old mud from any home improvement store. Then I tried a company called MudPaint, out of Boise, Idaho. I like their shades and non-toxic ingredients, but I realized too late that the paint is made for wood, and didn't perform well on textured drywall. I used it on a couple walls, and it looks fine, but chips so easily. I have to keep touching it up. But not a bad option for someone painting wooden surfaces or wooden walls!

Upstairs in my she-shed, I tried a different approach. I used the same texture clay as a base, then added in food powders of different kinds to get the natural colors I wanted: shades of greens from powdered herbs. I like horsetail the best for a light, sage-y grass color! I also used cocoa powder and beet powder. I mixed in water to get a paintable consistency, and here is how it turned out. Pretty cool, I think! The only downside is, it chips and scuffs easily and mixing the exact same color is challenging. So perhaps a different method would be best in a high-traffic area or home with kids. I suspect that is the same with all home-concocted paints. I'm ok with it, since I didn't have to suck down any fumes which could hurt my baby.  All in all, I painted about 324 square feet with the paint I made. Bonus: it was super cheap!

Does milk based paint apply here? The title seem to say so but the description is less clear. I've made mine with raw ingredients like fresh milk and bigs bags of clay (my home clay is red so i'd to buy some white one) and hydrated lime and bulk pigments.

Here's my BB for natural paint. I used home made milk paint for my bedroom ceiling. I didn't find the exact recipe i used, but it contained white clay and a bit of lime.

I made a clay paint and paint one one my she shed walls with it totaling 48 sq feet. I didn't want a red clay so I used kitty litter and was hoping for more of a gray than brown.

Edited to add dried paint and ingredients.

So far so good and we have had some heavy rain. This wall even faces west (where most of our weather comes out of)

I first needed to plaster the wall using a sifted chopped straw to prep it for paint. I used a wheat paste that I cooked up in a 4:1 ratio and cooked similar to a roux. Then I mixed it into my clay slip using subsoil and water after sifting it. The wall was a 5ft by 7ft = 35 sqft > 32sq ft; meeting the requirement.

It was easy to paint and now it hides the straw. I didn't use a pigment. I might paint a contrasting color on it using a red clay harvested in Moab in a few days if time allows to add embellishment.
