High-density smooth foam board with self-adhesive backing — 30 x 10 x 5 cm, approx. 100 g. Designed for modeling, building, crafts, diorama bases and creating miniature mountains or rockwork. Provides a stable, easy-to-shape core with basic sound-dampening and insulating properties. Key features and benefits Material and finish: High-density foam with a smooth surface that takes paint, glue and texture materials well for realistic finishes. Self-adhesive backing: Built-in adhesive layer speeds assembly and mounting, reducing the need for extra glue and saving time on projects. Accurate sizing: Precise dimensions (30 x 10 x 5 cm) and light weight (approx. 100 g) make planning, scaling and transporting models straightforward. Versatile performance: Firm enough to hold carved detail for rock faces and terrain, yet easy to cut, sand and shape with common hobby tools. Insulation and sound control: Provides basic thermal insulation and sound-dampening where a lightweight core is needed. Practical applications (examples) Dioramas and model railways: Carve and layer to build mountains, cliffs and terrain bases; paint and flock directly on the smooth surface. Architectural and scale models: Use as a precise, lightweight core for massing, mock-ups and finished display models. School projects and displays: Quick to assemble with its self-adhesive backing—ideal for classroom assignments, presentations and craft fairs. How to use Cut and shape with a hobby knife, hot wire cutter or fine saw for clean edges. Paint, glue and apply texture materials directly to the surface; adhesive backing allows fast bonding to many substrates. Combine multiple blocks for larger landscapes or layered height effects.
