Methods and processes for applying powder coat faux finishes, and power coat materials associated with such methods and processes are provided. Processes employ one or more partial powder coat layers along with physical texturing techniques to provide a variety of powder coated faux finish effects. Methods may utilize standard powder coating formulations in contrasting combinations to form suitable faux finishes. Faux finishing techniques using powder coating procedures may reproduce effects previously only obtainable with wet techniques, such as, for example, sponging, color washing, rag rolling, marbleizing, faux granite, strié, antiquing, verdigris, wood graining, weathered patina, etc. Kits of materials, including powder coating materials and physical texturing equipment suitable to reproduce such faux finishes are also provided.
