Finishes for Port Black

Polished

Mirror-like gloss that brings out colour and veining at full depth. The classic choice for walls, tops and interior floors; slippery when wet.

Honed

Smooth and matt, with a soft satin look. Hides small scratches and etching better than a polish and is safer underfoot.

Brushed

Worked with abrasive brushes for a slightly undulating, silky surface that follows the grain of the stone. Warm to the touch and easy to live with.

Sandblasted

A fine, even roughness obtained with a jet of sand. Lightens the colour and gives grip: used for exteriors, steps and pool surrounds.

Bush-hammered

A rough, pitted surface made with a toothed hammer. Maximum slip resistance for exterior paving, ramps and steps.

Care and maintenance

  • Clean with water and a neutral detergent made for natural stone; rinse and dry.
  • Avoid acids and descalers (vinegar, lemon, anti-limescale sprays): they etch calcite and dull a polished surface.
  • Seal with an impregnating protector after laying and repeat when water no longer beads, typically every 1–3 years on tops.
  • Wipe wine, coffee, oil and citrus juice straight away, especially on kitchen and vanity tops.
  • A dulled or scratched surface can be re-honed or re-polished on site: the stone is the same through its whole thickness.
