Two-sided applicator with reactive or complementary chemistries

Abstract: The invention described herein provides an applicator for applying a substance, the applicator including an application side and an opposed reactive side, the application side including an application substance and the reactive side including a reaction substance, wherein the application and reaction substances react with each other when the application and reactive sides of the applicator are sequentially wiped on a target surface. Also provided is a method for treating a target surface, the method including contacting the target surface with an application side of an applicator including an application substance, whereby the application substance is deposited onto the target surface; and thereafter contacting the target surface with a reactive side of the applicator including a reaction substance, whereby the reaction substance reacts with the application substance.
