Casey, Powdered paint formulas are really just paint formulas without the liquid ingredient, namely the water. Typical formulas contain the following solid ingredients: pigment (to provide the color) clay (thickens the paint when water is added) "binder" (a polymer that forms a film when it dries, typically corn starch or dextrin) preservative (powder that will destroy any bacteria or mold that is introduced) "filler" (extra solid stuff added to give the paint some volume and does not serve any particular purpose otherwise, such as calcium carbonate or another clay, etc.)
