How does pine’s susceptibility to UV damage affect outdoor figurative installations?

Pine wood is a popular choice for outdoor figurative installations due to its affordability and workability. However, its susceptibility to UV damage poses significant challenges for long-term durability. When exposed to sunlight, pine undergoes photodegradation, causing discoloration, surface cracking, and structural weakening over time. The lignin in pine breaks down under UV radiation, leading to a grayish appearance and reduced strength. This degradation not only affects the aesthetic appeal of sculptures but also compromises their structural integrity. To mitigate these effects, artists and conservators often apply UV-resistant sealants or paints, or choose alternative wood species with better natural resistance. Regular maintenance and protective coatings can significantly extend the life of pine outdoor installations while preserving their artistic value.
