A method to prepare a self-decontaminating surface, where that method includes disposing a first coating on a surface, where that first coating comprises an organosilane, and disposing a second coating over the first coating, where the second coating comprises TiO.sub.2.

Disclosed is a method for the formation of multi-layer paint films with the omission of a mid-coat paint coating process. The method comprises the use of a particular aqueous colored paint (A) comprising a prescribed amount of specified titanium oxide that has been compounded, The resulting multi-layer paint films have a very bright paint color, and especially a white or light-colored color, and have excellent concealing properties. The aqueous colored paint (A) is characterized by containing from 50 to 60 mass % with respect to the whole paint solid fraction of titanium oxide of specific surface area not more than 13 m.sup.2/g.

A superhydrophobic surface includes a substrate treated with a non-fluorinated, water-based composition including a hydrophobic component free of fluorine, a hydrophilic filler particle, wherein the filler particle is a metal oxide nanoparticle, and water, wherein the hydrophobic component is in an aqueous dispersion. Also, a superhydrophobic surface includes a substrate treated with a non-fluorinated composition including a hydrophobic polymer free of fluorine, titanium dioxide nanoparticles as filler, and water. In addition, a superhydrophobic surface includes a substrate treated with a non-fluorinated composition including a hydrophobic polymer free of fluorine, wherein the hydrophobic polymer includes a polyolefin; titanium dioxide nanoparticles as filler, wherein the titanium dioxide nanoparticles are rutile titanium dioxide, anatase titanium dioxide, or a mixture of rutile and anatase titanium dioxide; and water.
