Liberon Iron Paste is a black graphite paste producing a silver/black look to decorative cast and wrought ironwork in the home. It is specially suited for ornamental ironwork, cast iron grates, surrounds and fire irons. Reduces the possibility of rusting and does not flake off. This product bakes itself onto the surface, and can also be buffed to a high shine.

Apply the Iron Paste sparingly to the whole surface with a brush or cotton cloth. Allow to dry for a minimum of 4 hours before buffing with a brush or cotton cloth. To obtain a decorative, patinated finish on sculpted or high relief pieces, carefully polish the raised area with a cotton cloth.
