Shale Stone Panel

Shale standing on edge: thin plates, 2 to 6 mm thick, packed vertically and breaking at different heights. The sharpest texture in the range, and the whitest.

The pattern is a wall of thin shale plates seen edge-on, so what you read is the plate edges, not the faces. They vary in height by up to 20 mm, which gives the wall a ragged top line every few centimetres and a shadow that changes with the light.

Fifteen millimetres and 12 kg, which makes it the heaviest sheet per square metre in the range. It needs the depth because the plates stand proud, and it needs a flat substrate because there is no give in the pattern: a hollow in the wall shows as a dark patch. It is specified as shale stone for feature walls in white interiors, where the split edge gives the room its only shadow.

Edges, not faces

Almost every other texture here shows you the face of the stone. This one shows you the edge, which is why it looks sharp and a little uncomfortable, and why it works so well in a white gallery where everything else is flat.

Gallery, then bathroom

The gallery is a single wall in the white, 3 m high, with a bench in front of it and nothing else in the room. The bathroom is the same sheet behind a freestanding bath, where the plates throw a shadow across the water.

Shale Stone installed in a gallery

Installed, shale stone

Good for

  • Gallery and museum walls
  • Bathroom walls behind a bath or a basin
  • Feature walls in rooms with a lot of daylight
  • Exterior walls in a dry climate, on a drained frame

Not for

  • Corridors and anywhere a sleeve will brush the wall: the plate edges are sharp
  • Kitchens and family bathrooms
  • Walls with a poor substrate

White, chalk, grey

Three, all pale: the white in the shot, a chalk and a light grey. Anything darker and the plate edges stop reading, which defeats the point of the pattern.

Fitting it

Four steps, and the third one is the one that goes wrong.

01 SurfaceFlat to 3 mm over 2 m, dry, dust free. Prime porous substrates.
02 AdhesivePolymer adhesive, notched trowel, full bed. Not dots.
03 Set outWork from a datum line, not the floor. Dry-lay one row first.
04 JointButt tight, or a 2 mm shadow gap. Roll the face after fitting.

Questions we get asked

Are the edges sharp?

They are as sharp as the mould allows, which is close to a real shale edge. Keep it out of reach in a family house.

Why is it the heaviest?

12 kg/m², because the plates stand proud and the sheet has to be 15 mm to hold them.

Does it collect dust?

Yes, in the gaps between plates. A soft brush, dry, once a month.

Can it be used in a shower?

Not recommended. The plate edges hold water and the pattern is difficult to seal evenly.
