Lightweight Hydrocal (WOOC1201)

Lightweight Hydrocal is a lightweight casting plaster designed for terrain model builders, ideal for creating rock formations and other terrain features.

Its formulation is about half the weight of traditional Hydrocal, making it easier to handle when assembling larger landscapes. Mix according to the instructions and pour into rock molds to form a range of formations, or use it to build hard-shell terrain and to fill in around rocks and other castings. Each batch yields roughly half a gallon (about 104 cubic inches) of material.
