Modeling clay Staedtler FIMOair Granite Effect 350 g Grey — air-dry modeling clay

Staedtler FIMOair Granite Effect is a 350 g air-dry modeling clay in grey that recreates a natural granite-like texture without the need for baking. Formulated for adult crafters, this ready-to-use modeling material hardens at room temperature and yields a stone-like surface suitable for small sculptures, reliefs and decorative objects. The clay arrives in a resealable polybag and offers a smooth, non-sticky feel that is easy to shape and blend.

Advantages

FIMOair Granite Effect provides a realistic stone appearance while remaining lightweight compared with real rock. Its formulation contains at least 80% natural raw materials and has been tested by independent toxicologists to meet safety expectations for creative use. Once fully dried, the surface can be sanded, filed, drilled, painted or varnished to achieve the desired finish. The material is convenient for projects where oven curing is impractical or unavailable, and the texture helps conceal fingerprints and minor tool marks.

Suitable for

• Small sculptures and figurines
• Reliefs and bas-relief decorations
• Home decor elements and ornaments
• Craft and hobby projects with a stone-like finish
• School and educational art activities

How to use

Knead the clay briefly to achieve an even consistency before modelling. Shape or sculpt the material using hands and common modelling tools; the granite texture helps to mask minor tool marks. Leave models to dry horizontally at room temperature until fully hardened — drying time depends on thickness and ambient conditions. After complete drying, refine surfaces by sanding or filing, and apply paints or varnishes if a different colour or protective finish is required.

Usage recommendations

For best results, keep individual model thicknesses moderate to ensure complete drying; allow extra drying time for thicker pieces. Store unused clay in its polybag or an airtight container to prevent premature drying. When painting, test compatible paints and primers on a small dried sample to confirm adhesion and desired appearance.
