    • What is the best way to make a tunnel?

      Tunnels can be made in a variety of ways.

      Ready Landforms are an easy way to add a tunnel. They are preformed, landscaped and ready to place on a layout. Available in HO and N scales and straight or curved designs.

      Self-supporting Shaper Sheet is another easy way to add a tunnel. Form into tunnel shape and arrange over track. Cover in Shaper Sheet Plaster and add landscape materials. For added realism, paint underside of Shaper Sheet to resemble blasted rock.

      Use 1/4" Foam Sheets or 1/4" Modeling Sheets to make tunnel walls and roof. Use No-News Paper or newspaper to add paper wads around the tunnel foundation to model terrain, and add a double layer of Plaster Cloth to form a hard shell.

      Use the Tunnel Liner Form to mold tunnel sections from Lightweight Hydrocal, Shaper Sheet Plaster or Super Strength Plaster. Connect sections together with Plaster Cloth to form desired length of tunnel.

    • Will Lightweight Hydrocal clog a water drain?

      You should not wash any Woodland Scenics plaster product down the drain. This includes Shaper Sheet Plaster, Carving Plaster, Super Strength Plaster, Lightweight Hydrocal Plaster, Mold-A-Scene Plaster, and Smooth-It.

      Plaster residue that remains after applying Plaster Cloth should also be discarded in the trash.

    • Will hills made with the ReadyGrass Mat be strong enough to support lead miniature wargaming figures? Lots of them, and for long periods of time?

      For this application, we suggest using Shaper Sheet and Shaper Sheet Plaster. Shaper Sheet is a revolutionary material that can be shaped and reshaped to form terrain with any level of detail. When covered in Shaper Sheet Plaster, it becomes a very durable surface that will support heavy game play.

      Cover Shaper Sheet Plaster in landscape materials to model a realistic gaming terrain.

    • Can I use Shaper Sheet Plaster in your rock molds?

      Yes. Shaper Sheet Plaster provides excellent detail when used as a casting plaster.

    • Is Shaper Sheet plaster required for a hard shell or will Hydrocal or others work as well?

      Any of our plaster-based products can be used on Shaper Sheet to create a hard shell, but deliver varying degrees of hardness. Reference the plaster chart on our website for details.
      Lightweight Hydrocal Plaster
      Carving Plaster
      Super Strength Plaster
      Mold-A-Scene Plaster

      We recommend using Shaper Sheet Plaster (C1180) because it has an extended working time and the hardness factor. The extended time allows the modeler more time to apply plaster. Typical plaster products have about 5 minutes of working time, while Shaper Sheet Plaster has approximately 20 minutes.

    • Can I sand shaper sheet plaster?

      When dry, Shaper Sheet Plaster is sandable.
