To make eco-graffiti, say goodbye to aerosol cans! Thanks to a moss base mixture replacing the aerosol can, green graffiti or eco-graffiti are growing on walls.
Appreciated by enthusiasts of Guerrilla gardening, this vegetable street art orientated urban hacking, the moss graffiti allows you to leave tags without damaging buildings whilst waiting for the moss to grow… On WikiHow a dead simple and cheap recipe enables you to prepare the mixture in four stages, cooking recipe style, far from appetizing, but 100% natural. Get mixing!
Beer , buttermilk , yogurt and moss
For the mix, make sure you have one or two tufts of moss, two cups of buttermilk or plain yogurt, two cups of water or beer, 1/2 a teaspoon of sugar and corn syrup.
Rinse the moss in order to remove the earth from the roots. Crumble it and place it in a blender. Add the buttermilk or yogurt, the water or beer and the sugar. Blend until you get the thickness of a consistent paste similar to the texture of conventional paint. If the mixture is too thick, add corn syrup to dilute it.
The moss paint is then applied with a paintbrush. Check once a week if the graffiti is growing properly. Spray it with water or add a layer of moss paint if needed. Depending on the care given, the atmospheric humidity, the moss grows, but not that quickly…
