Method of forming a very hydrophobic, extremely hydrophobic or superhydrophobic surface comprising depositing a composition comprising hydrophobic microparticles, hydrophobic nanoparticles, or a mixture thereof and a binder in sufficient quantity to provide a hydrophobic or a superhydrophobic surface on a substrate having a micropatterned surface having raised portions, recessed portions or a combination thereof. Procédé de formation d'une surface très hydrophobe, extrêmement hydrophobe ou super hydrophobe comprenant le dépôt d'une composition comprenant des microparticules hydrophobes, des nanoparticules hydrophobes, ou un mélange de celles-ci et un liant en quantité suffisante pour former une surface hydrophobe ou super hydrophobe sur un substrat présentant une surface microstructurée avec des parties en retrait, des parties en relief ou une combinaison de celles-ci.
