The range of Diorama Effects offers the modeler everything needed for the reproduction of a terrain, with effects of sandy and dusty roads, or of snow, mud and water, all of which add to the realism of the setting and relate the model to its environment. Rough Grey Pumice is a heavy paste of resin and natural pumice stone, with a rough grey finish, for surface building and irregular terrain, reliefs and peaks.
