This Liberon Iron Paste is a black graphite paste used to protect and decorate cast and wrought ironwork. It does not flake off, and is suitable for home decorating. Especially suited to ornamental ironwork, cast iron grates, and fire irons. Ideal for renovating cast iron fire places and surrounds. Reducing the possibility of rusting, it bakes itself onto the surface, and can be buffed to a high shine. Drying time: Minimum of 4 hours.
