Natural
Natural uncoated grey
Untreated mineral appearance. Each panel is unique. Batch variation is expected.
What it is
Uncoated, high-density grey fibre cement board. Lightly sanded surface with visible fibres, specks and tonal variation. Supplied without a factory-applied water-repellent treatment. Use and suitability are not stated on this page until Skanfas delivers and approves that material.
Expressions
Colour
Natural grey only
No standard colour options and no colour matching. Edges are untreated cut edges as standard.
The board
Natural
The finish strip stays in place. The turnable board loads only after you open it. It shows face, thickness and edge from that strip. It is not a CAD model.
Finish strip from the 2026 image set. Not a CAD model. The thickness is a geometric study, not a measured sample.
Formats

- 1220 × 2500 mm

These are the sizes the calculator is allowed to count. Not an installation layout.

Reserved frames are empty on purpose. The finish strips already delivered are not requested again. Send a new photograph in sRGB, as JPG or WebP, at the size named on the frame, with no watermark. Vivid, Rough and Heavy-Duty still need a face photograph. Skanfas confirms the rights before a picture is published.

The figures that remain describe the uncoated grey board in the 2026 extract. They are not a suitability statement. No separate approved Natural pack has been delivered for use or application claims, so none are added here. The base-board Declaration of Performance is supplied separately and takes precedence.
