Whether to seal gold leaf depends on the metal, karat, surface, location, handling, and desired appearance. Genuine high-karat gold often does not need the same protection as imitation leaf or silver leaf, but exterior exposure, abrasion, and tarnish-prone metals may require a compatible coating.
For suitability questions involving substrate, exterior exposure, restoration, food or cosmetic use, availability, or current manufacturer guidance, contact SeppLeaf technical support.
