Need A Hard Coat For Foam?
Many prop and scenic projects are built from carved foam such as XPS or EPS. These materials are lightweight and easy to shape, but they need the right coating before painting, finishing or repeated handling.
Rosco scenic coatings are used to:
- Harden rigid foam surfaces
- Create a paintable scenic shell
- Protect props and scenery from wear and handling
- Provide either a rigid or flexible coating path depending on the substrate
Recommended Rosco Scenic Coatings
Rosco Foamcoat
Best when you need a hard, sandable shell on XPS, EPS, polystyrene and carved rigid foam props, sculptures, rocks, facades and scenic elements.
- Creates a hard shell surface
- Sandable and paint-ready once cured
- Excellent for scenic paint finishes
- Ideal for rigid foam props and set pieces
Rosco Flexcoat
Best when the build needs to bend, compress, travel or absorb impact, including flexible foam props, EVA foam, soft scenic elements and touring pieces.
- Flexible protective coating
- Helps resist cracking on moving surfaces
- Paintable with scenic paints
- Better when a rigid shell is not suitable
Not Sure Which Coating You Need?
Choosing the right scenic coating depends on the foam type, the flexibility required, and the final finish you want to achieve.
