Manetti Water-based liquid Bitumen for patina

Water-based liquid bitumen is a ready-to-use mixture suitable for patinating and aging gold surfaces.Bitumen can be used for both the maintenance and ageing of gold surfaces. The product is best applied with a pad or a brush (perla synthetic hair brush SERIES, p. 125) over the entire surface to be treated, allowing the lower layer to absorb it. Excess product on the surface after application must be removed. The bitumen can be diluted, if necessary, with turpentine.
