The surface spraying process for urban outdoor metal furniture demands specific environmental conditions to ensure optimal adhesion, durability, and finish quality. Ideal temperatures typically range between 15-30°C (59-86°F) with relative humidity maintained below 65% to prevent moisture-related defects. The spraying area must be completely protected from wind, rain, and airborne contaminants such as dust or pollen that could compromise surface integrity. Professional applications often utilize controlled spray booths with proper ventilation systems to manage overspray and maintain consistent conditions. Surface preparation requires a clean, dry environment free from oil, grease, or previous coating residues. Additionally, adequate lighting is essential for identifying surface imperfections before, during, and after application. These controlled conditions help achieve uniform coating thickness, proper curing, and long-lasting protection against urban environmental factors including pollution, UV exposure, and temperature fluctuations that outdoor furniture routinely encounters.
