Do You Recommend To Apply Clear Coats On Copper And Zinc?
Discover the fascinating world of copper patination in this enlightening conversation with a metal expert who shares invaluable insights about how copper transforms over decades. Far from being a defect, the changing colors of copper tell a story of natural protection and evolution – from gleaming new installation to light brown, dark brown, and eventually the iconic verdigris green after approximately twenty years.
The complexity behind copper's relationship with its environment, with factors such as UV exposure, vegetation, acidity levels, and even bird droppings influence the rate and pattern of patination. This unpredictability creates unique finishes that blend structures harmoniously with their surroundings, though not all clients appreciate this natural aging process. Through colorful anecdotes, including a disappointed homeowner who believed her darkening copper bay window was "defective," we explore the critical importance of setting proper expectations when working with living metal finishes.
Beyond aesthetics, copper offers remarkable functional benefits worth considering for both exterior and interior applications. Its natural antimicrobial properties can kill harmful microorganisms – even COVID-19 within three hours – making it an excellent choice for frequently touched surfaces. However, applying clear coats to preserve copper's initial shine actually inhibits these health-protective qualities.
Whether you're a homeowner, architect, or design enthusiast, this episode will transform how you view the living canvas that is architectural copper.
