Yes, Foam Putty can be painted. The dried surface of Foam Putty is gritty. For a smooth surface, sand dried Putty with a very fine grade sandpaper (220-400 grit) before painting. Apply two coats of paint, sanding lightly between coats.
The "n" stands for narrow. On30 describes the modeling of narrow gauge railways, using O scale trains with narrow tracks that run on HO gauge track. For your On30, you can use SubTerrain Risers and Track-Bed.
We do not have a layout kit in O scale.
For O scale, we recommend the Mod-U-Rail System. Mod-U-Rail uses our SubTerrain Lightweight Layout System and allows you to design, build and landscape a layout that is customized to your specific space and scale requirements.
You can also design and build a layout using the SubTerrain Lightweight System.
Shaper Sheet is a terrain modeling material. It is not intended to be used as a level surface for running trains. To elevate track and create smooth elevation transitions, we recommend using Risers and Inclines/Declines as a track foundation. Cover Risers and Inclines/Declines with Plaster Cloth, and then form terrain contours with Shaper Sheet and attach it up against the edge of the Risers and Inclines/Declines.
Yes. SubTerrain foam products are made from unique, high-density foam and will not crumble or fall apart.
We wanted a foam product that was lightweight and easy to use. You can cut SubTerrain quickly and neatly, it will not crumble or fall apart, and working with SubTerrain high-density foam rquires no previous modeling experience. When cut with a Hot Wire Foam Cutter, it does not emit toxic fumes.
