This is a special grey earth powder that will form very authentic, up to scale terrain with beautiful texture. It has the color of grey primer, so once you fix it using VMS Sand & Ballast Freeze you will see exactly how the structure will look like when painted, which is impossible with white generic materials such as plaster. Fix using VMS Sand and ballast freeze or VMS PVA glue. Paint over to change the tone to any one you like. Particle size: 0.001 - 0.5 mm.
