The Woodland Scenics Boulders Rock Mold casts big, deeply detailed boulders for quarry sites, mining operations, road cuts, canyon walls, ditches and anywhere your layout needs rugged rock. The flexible, reusable 5" x 7" mold releases 39 individual boulders in a single pour and works in any scale — HO, N, O, S, G and Z.
Round out your rockwork with the rest of our Scenery & Landscaping supplies, including plaster, pigments and companion Woodland Scenics rock molds.
What plaster should I use with this mold?
Woodland Scenics recommends Lightweight Hydrocal, Super Strength Plaster or Shaper Sheet Plaster for the strongest, most detailed castings.
How do I get the boulders to release cleanly?
Lightly mist the mold with "wet water" (water plus a few drops of dish soap) before pouring, then flex the cured mold to pop the rocks out.
Is the mold reusable?
Yes. The flexible polymer mold can be used for as many castings as you need.
What scales does it work with?
Any scale — the assorted boulder sizes look at home on HO, N, O, S, G and Z layouts.
