Finishes for Gritstone
Honed
Smooth and matt, with a soft satin look. Hides small scratches and etching better than a polish and is safer underfoot.
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.
Natural cleft
The stone is split along its natural layers and left as it is: a lively, riven surface with excellent grip.
Care and maintenance
- Clean with water and a neutral detergent; hard stones tolerate everyday use very well.
- Sealing is quick and recommended on light colours and on honed, leathered or flamed finishes.
- Avoid waxes and film-forming products that leave a layer on the surface.
- Outdoors, an occasional wash with a pressure cleaner at moderate pressure restores the colour.
- Hot pans, knives and frost are not a problem for most stones of this family; use trivets anyway to protect sealers.
