What are the effects of acid rain on the surface of resin outdoor sculptures?

Acid rain poses a significant threat to resin outdoor sculptures, causing both visible and structural damage over time. The acidic components in rainwater, such as sulfuric and nitric acids, react with the resin surface, leading to discoloration, fading, and a loss of detail. Prolonged exposure weakens the material, making it brittle and prone to cracks. Additionally, acid rain can accelerate the breakdown of protective coatings, leaving sculptures vulnerable to further environmental damage. To mitigate these effects, regular maintenance, protective sealants, and sheltered placement are essential for preserving resin art in outdoor settings. Understanding these risks helps artists and collectors take proactive steps to safeguard their investments.
