Grumbacher - Japan Drier

Japan Drier

Speed oil paint drying while enhancing flow and building rich gloss

Traditional formulations exist for good reasons. Japan Drier accelerates oil paint drying through metallic salt catalysts that promote oxidation, the chemical process that actually hardens oil paint. A few drops mixed into slow-drying colors like ivory black or alizarin crimson can reduce waiting time between layers from days to hours, maintaining momentum on multi-session paintings.

This medium does more than speed things up. Paint flows more smoothly from the brush while developing increased gloss as it cures, useful when you want luminous darks or rich color saturation. The 2.5-ounce bottle provides enough for extended use since effective doses remain small, too much drier can cause cracking or yellowing over time.

Use Japan Drier strategically rather than universally. Reserve it for underlayers that need to dry quickly or specific problem colors that refuse to set up. Fast-drying passages let you return to work sooner, while untreated areas maintain normal working properties. Grumbacher's formulation follows established recipes that generations of painters have relied on when deadlines loom or layering sequences demand faster turnaround than standard oil paint naturally provides.
