Rongji Stone Panel
Stone worked with a scraper rather than a chisel: long diagonal sweeps, torn where the tool jumped, and a surface that looks more like set plaster than like rock.
Technical data sheet, MBRJY (PDF, 0.9 MB)·Colour card, 106 surfaces in four series (PDF, 10.4 MB)
The pattern came off a sample of grey stone that had been finished with a wide scraper, which is a finish you see on Venetian plaster and almost never on stone. The sweeps run across the sheet at about 30 degrees, 40 to 100 mm wide, and each one tears a little at the end.
Fifteen millimetres and 10 kg on a 1160 × 2950 sheet. This is the deepest press in the range, and the reason is the sweep: a 40 mm wide tool mark needs 15 mm of material to stand in, or it reads as a scratch. Two people to hang, and a flat wall behind it. Bought as a decorative stone panel for gallery walls and stairwells, and at 15 mm the thickest press we run.
A tool mark, not a texture
The thing that makes this one convincing is that the sweeps are not parallel and not the same width. A machine pattern would give you a consistent 60 mm band at a consistent angle; here the tool wandered, the angle changes by ten degrees across the sheet, and some sweeps stop halfway.
Good for
- Gallery and museum walls
- Stairwells and landings
- Hotel lobbies with a skylight
- Walls where a plaster finish is wanted but durability is not negotiable
Not for
- Small rooms; the sweeps need four metres
- Anywhere the wall will be seen close up and touched, because the torn edges are sharp
- Floors
Grey, and two earths
Three: the mid grey in the shot, a warm earth and a chalk. On a scraper finish the grey is the most convincing, because it is the colour that a real scraped limestone would be.

Questions we get asked
Is the scrape a real tool mark?
It is a mould taken off a real scraped sample, so the tears and the changes of angle are the original ones rather than a drawn repeat.
Why 15 mm?
The tool mark needs depth to sit in. At 8 mm the same pattern reads as a surface scratch rather than a sweep.
How heavy is a sheet?
A 1160 × 2950 at 10 kg/m² is about 34 kg. Two people, and a frame if the wall is not flat.
Can it be used outside?
Not recommended. The sweeps hold water on a vertical wall, and the colour is interior grade.
