Many products that are situated outdoors are powder coated both to protect and to beautify the article. These powder coated articles can include such diverse products as garage doors, letter boxes, meter boxes, plant pots and fencing products. Powder coating is one of the most durable color coatings available and, with minimum effort, it will provide many years of excellent wear and service. To maximize the life of powder coated articles and to comply with warranty requirements for powder coated ferrous and nonferrous parts, a simple but regular maintenance program must be implemented. The effects of ultra violet light, atmospheric pollution, dirt, grime and airborne salt deposits can all accumulate over time and must be removed at regular intervals to prevent corrosion, fading and pitting. As a rule regular cleaning must take place at three monthly intervals, in areas where pollutants are more prevalent or atmospheric conditions are more extreme, such as beachfront premises, industrial or geothermal areas, then a cleaning program should be carried out on a more frequent basis every one to two months. The maintenance requirements are set down in the Australian Standards document AS/NZS 2312:2002 ‘Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings
