Aged Look Coating: Important Warning for Exterior Steel

Summary for aged look coating Discussion

aged look coating product is the core question here: Carla L., an architecture firm in Austin, asked whether there is a manufactured finish for an exterior steel storefront in an Irvine, California mall that would give the steel an aged or patina appearance. The answer from one contributor cautions that a simple oxidation or patina coating on plain steel would not provide enough corrosion protection for exterior use. The advice is that such a finish may achieve the desired color or shading, but the steel would still rust. Instead, the responder suggests electroplating the steel with another metal and then patinating that metal, rather than relying on a patina applied directly to bare steel. The thread is brief and presents one clear practical warning: appearance alone is not enough for an exterior storefront, and durability must be addressed first.
