Japan Drier —

Grumbacher Japan Drier is a reliable alkyd resin-based liquid siccative intended for use by sign painters, artisans, and craftspeople. Japan Drier is not generally recommended for fine arts applications because it has a tendency to yellow and darken oil colors over long periods of time. It is an ideal medium for oil gilding. Simply apply Japan Drier to an appropriate surface and allow it to dry to a high tack, then apply gold or silver leafing, smooth, and burnish.
