This chapter addresses the challenges of conserving street art, focusing on a sustainable hybrid coating made of chitosan and nanosilica. This coating protects murals from environmental damage while preserving their visual appeal. Physico-chemical characterization confirms its strong protection, compatibility with various surfaces, and breathability. Studies on mock-ups and accelerated aging tests validate its durability and stability, making it a promising solution for the long-term preservation of contemporary murals. The chapter also presents data from monitoring a real case, proposing a potential application for this protective coating.
