A must-have product for any modeler who wants to add volume to their mud and soil mixtures, whether it is for a diorama or to be splashed onto their vehicle. Mix the plaster in with any of our high-quality Nature Effects line of different types of mud, earth, dust, and soil. The combinations are endless. If your mixture is too thick, you can dilute it with white spirit. If it is too thin, add more plaster. Either paint your mixture onto your diorama or load a paintbrush with your mixture and, using your airbrush, blow short bursts of air at the brush to recreate splatters.
