This 100% natural product is accurately scaled for HO mainline ballast, with grains representing rocks from 1.8 to 3.4". The natural color is dark tan and can be custom colored with ink+alcohol to provide a variety of colors.
Available in 32oz shaker bottles in several colors.
Spray your roadbed base with "wet" water (water with detergent or alcohol), pour the ballast, brush off the ties and into the desired profile. Spray again with wet water, then liberally apply dilute adhesive with an eye-dropper or pippette.
