Summary for copper floor sealant Discussion
Copper floor sealant is the central issue in this thread: Yvonne Tavares asks how to protect decorative copper sheeting used as a large kitchen floor so it will not patina, and Gail Dean later asks whether a maintenance solution was found. The only answer advises caution: the responder says they do not have direct experience with this exact flooring use, but believes any sealant will either react with the copper or still allow it to breathe and oxidize over time. To keep the copper bright, they recommend first treating it with benzotriazole, described as a copper preservative, before applying a lacquer, clearcoat, or resin. The answer also notes that related threads on preserving copper brightness in sculptures, artwork, countertops, and decorative items may offer additional ideas. No specific product or service is confirmed as a definitive solution.
Q. I am a homebuilder that is looking for a way to seal decorative copper sheeting that will be used as the floor for a large kitchen area. The floor will be made of copper and will therefore require a sealant that will protect the floor and keep the copper from getting a patina. Does anyone know of a product and/or service that will enable me to seal copper in such a manner that will make it into an effective flooring? Resin perhaps?

Q. I have the same question. Did you ever come up with a solution for maintenance of a copper floor?

A. Hi. Although I don’t have personal experience with the exact situation, I think whatever sealant you put on it will to some extent either react with the copper or let the copper breathe and oxidize. Therefore, to keep it bright I think you will need a treatment with benzotriazole

(copper preservative) before applying the lacquer, clearcoat, or resin. Good luck.
We have any number of
threads about preserving the brightness of copper in sculptures, artwork, countertops, and decorative items, and there may be food for thought in some of them. Good luck.
