Weather Resistant Homemade Paint 5 parts cottage cheese or dry curd cheese (Dry curd cheese is cottage cheese without cream or flavoring added. You can make a similar cheese by putting cottage cheese into cheesecloth and hanging it until it stops draining. Use cottage cheese if you’re in a hurry.) 1 part hydrated lime or slacked lime Mix hydrated lime with water to make a paste. Add to cottage cheese and stir in well. Leave for few hours - the cheese lump will dissolve completely. Select some powder pigments and add to solution (Pigment powder must be lime proof)--You can use homegrown dye as paint pigment. Add more water if too thick; powdered skim milk if too thin. Strain if you want a fine paint (old nylon stocking works well).
