    The protection of surfaces, especially metals, ceramic, glass, fabric, wood, and mineral surfaces, from stain, scratch, water absorption, etc, is best accomplished by going the nanotechnology route, via nanohydrophobic coatings. These coatings are sprays on liquids that will protect the surfaces of materials. Such exercise provides benefits, among others: good waterproofing and stain repellent, resistance to scratch, oleophobic and superhydrophobic features. Ordinarily, paints are liquids that are employed to coat a solid surface in order to protect, seal, or color such solid surfaces. Therefore, paints containing nano-silicon dioxide (nano-SiO2) do improve the macro- and microhardness, abrasion, scratch, and weather resistance, while nano-titanium dioxide (nano-TiO2) in addition to paints can significantly improve photocatalytic activity and also advance the material’s UV protection. Paints containing nanosilver (nanoAg, i.e., Ago) particles inclusion provide an astonishing antimicrobial properties against bacteria and human pathogens, even though nanosilver and nano-titanium dioxide may not fully prevent microbial and algal growths.
