Vallejo Diorama FX – Coarse Pumice Stone (26213): rocky texture for realistic dioramas

In the Diorama FX range by Vallejo, the Coarse Pumice Stone product (26213) stands out by offering a powerful rocky texture thanks to a thick paste made with resin and natural pumice particles. This variety lets you recreate rugged terrain, irregular reliefs, and coarse surfaces with strong realism, seamlessly integrating your model into an eroded-like environment. All Diorama FX products are acrylic-based (non-flammable, solvent-free) and easily applied with brush, spatula, or palette knife.

Perfect for rock formations, mountains, cliffs, and eroded zones, this effect is applied in layers to build volume. You can mix it with water or gel base to soften the roughness, or combine it with gravel or sand textures to enrich the scene.
