![]() Ron Young, a highly regarded metallurgist who was known throughout the world for his knowledge and use of patinas, authored the two books on the subject, "Methods for Modern Sculptors" and "Contemporary Patination." Finish with a wax coating if more protection is desired. Two or three lighter coats are better than a single heavy coat, allowing the piece to dry between coats. Once the desired patina has been achieved, seal the piece with a clear sealer, metal oil or wax. Use two different finishes, one on top of the other, to achieve different effects. As the chemicals react with the metal surface, a colored pattern appears. Then, depending on the formulation, allow the finish to sit for a few minutes up to a day. Following directions for the particular finish, immerse the object in the stain or dye, or spray, brush, sponge, roll, or rub it on. Different finishes may require the surface of the metal to be either hot or cold (room temperature). Make sure the piece is completely dry before proceeding. Or, use a wire wheel or vinegar to etch the surface lightly. For some processes, the surface can be cleaned and abraded with an electric sander or sand blaster to better allow dyes or coatings to adhere. Be sure not to touch the piece with your hands, which would leave behind unwanted oils. The metal must be clean and free of any grease, dirt, rust or scale using a metal cleaner and degreaser. Work outside if possible, or in a location with adequate ventilation. Be sure to wear appropriate personal protective equipment, such as gloves, goggles or safety glasses, and a respirator if needed. Watch this video about selecting the right patina based on ideal look, metal alloy, and layering options.įollow these basic instructions for creating a patina. Not all patinas, waxes and oils can be applied to all metals, so be sure read the instruction. Thanks to modern metallurgical science, a patina can make any metal finish "come to life with rich surfaces and vivid colors." Different metals, such as galvanized aluminum, tin, stainless, iron, bronze, and copper, produce different patterns and colors using different types of finish. A patina isn't just copper gutters turning green with age – it is the coloring of any metal surface by natural weathering or chemical "rusting" with acids. It is considered to be both more energy and material efficient than other colouring techniques.Whether you are creating an artistic sculpture or an architectural design, sheet metal finishes are easy to achieve. PPC aluminium products are an excellent choice if you’re looking to make your project as environmentally friendly as possible. It also achieves outstanding colour retention in outdoor exposure where heightened weather resistance is required. Polyester Powder coating is designed to eradicate any imperfections such as drips, which are common with painted finishes. Strong corrosion resistant properties make it both extremely durable and long lasting.īy choosing PPC aluminium you ensure a superior finish. Powder coating is a three-step process that includes preparation, appliance and treatment.ĭue to being designed specifically for external use, polyester powder coating leaves really hard finish that is much tougher than normal paint. By using this electrostatic powder process, we ensure that fabrications of any size and shape can achieve an even finish.Īluminium is a metal that is commonly powder coated to give it a durable finish and decorative appearance. It is applied to architectural fabrications electrostatically and then left under heat to allow it to form a protective ‘skin’. Polyester powder coating is a type of dry coating which makes an alternative to conventional liquid paint. ‘PPC’ stands for polyester powder coated, which is a colouring process used within architectural fabrications to achieve bold and bright finishes, including a full range of metallic colours. Unit 25 Cambridge Science Park – CambridgeĪll Metalline’s PPC aluminium products are renowned for their functionality and can be obtainable in every RAL or BS colour.3 Glass Wharf, Temple Quarter – Bristol.Ultima A1 & A2 Fire Rated Insulated Spandrel Panels.
