Pigments are the modeller's secret for the finest dust, dirt and grime, and this burnt umber tone brings a deep, warm brown to your weathering. Use it for rich shadows, dark earth and grimy staining, working it into recesses to add depth to the lower areas of a model.

Apply the fine powder dry for a dusty finish or fix it in place with pigment fixer or thinner, working over a matt surface for the best grip. Browse the full AK Interactive weathering effects range for more to build up alongside it.
