A water based paint that can be used to form a superhydrophobic coating includes a fluorinated particulate filler, a water soluble or water suspendable resin, and an aqueous solvent. The superhydrophobic paint can be applied to a surface where the loss of the solvent results in a superhydrophobic coating.
