Technical
Finish is the largest single lever on wet performance and on laying tolerance. All six finishes are produced in house on four lines, so a scheme can mix them from one bench and one order.
01 / Table
Wet pendulum values are measured on the finish as supplied, not on a reference face.
| Finish | Process | Thickness | Wet PTV | Intended use | Stones |
|---|---|---|---|---|---|
| Natural riven | Split along the natural bed, edges sawn square | 18–24 mm nominal | 44–48 | External paving where texture and wet grip lead | Grey, Yellow, Maroon |
| Honed 220 grit | Calibrated then abraded through four heads to a matt close surface | 16 / 20 / 25 / 30 mm | 34–39 | Commercial paving, flooring, cladding | All four |
| Polished | Abraded through eight heads and buffed, no resin or wax | 16 / 20 mm | 22–26 | Interior floor and wall only | Maroon, Cream |
| Shot blasted | Steel shot at controlled pressure over a calibrated face | 20 / 25 / 30 mm | 46–52 | Wet external areas, ramps, thresholds | All four |
| Bush hammered | Mechanical point hammering, medium pitch | 25 / 30 / 125 mm | 54–60 | Kerbs, steps, heavy trafficked entrances | Grey |
| Sandblasted and brushed | Light blast followed by abrasive brush heads | 16 / 20 mm | 38–43 | Interior floors, softened arris detail | Yellow, Cream |
02 / Line
Four lines: two calibrating, one honing, one polishing. Calibration precedes every finish other than natural riven.
| Calibrating lines | 2, maximum 1200 × 800 mm |
|---|---|
| Honing line | 1, four abrasive heads, 220 grit finish |
| Polishing line | 1, eight heads, no resin or wax |
| Blasting cabinet | Steel shot, 1200 mm bed width |
| Thickness tolerance | ± 1.0 mm calibrated, ± 3.0 mm riven |
| Edge | Sawn, rectified or hand dressed to order |
| Water | Closed loop, 82 % recovery |
03 / Availability
Not every finish is offered on every bed. Polished is interior only.
| Natural riven | Split bed face, 18–24 mm nominal, sawn edges |
|---|---|
| Honed 220 grit | Calibrated, matt, most specified for commercial paving |
| Shot blasted | Uniform open texture, raises wet PTV |
| Bush hammered | Kerbs, steps and heavy trafficked thresholds |
| Natural riven | Split bed face, strongest wet-dry contrast |
|---|---|
| Honed 220 grit | Calibrated, even matt buff |
| Shot blasted | Recommended for wet external areas |
| Sandblasted and brushed | Softened arris, interior and threshold use |
| Natural riven | Split bed face, strongest colour depth |
|---|---|
| Honed 220 grit | Calibrated, even matt, most specified for cladding |
| Polished | Interior only, closes surface and lifts tone |
| Shot blasted | External paving and thresholds |
| Honed 220 grit | Standard interior floor finish |
|---|---|
| Polished | Lobby and wall applications, low traffic |
| Brushed | Softened matt, hides traffic marking |
| Shot blasted | Wet rooms and thresholds |
