All Birchwood patinas are considered traditional patinas that will age or darken metal. Most of these patinas are sold concentrated and should be diluted with distilled water (up to 50%) before use. Once diluted, one gallon of Birchwood Liquid Patina generally covers 200 sq. ft.
Birchwood Liquid Patinas are available in 8oz., 32oz., 1 gal., and 5 gal. sizes. Spray tops are included with 8oz. and 32oz. bottles. A clear sealer should be applied when completed to protect the finish.
