What it is
The grey of the UK garden
Kandla Grey is a fine-grained, quartz-based natural sandstone quarried in Rajasthan, India. It has a soft grey to blue grey tone with subtle veining and only occasional buff or beige shading, which makes it one of the most even colours in Indian sandstone.
That consistency is why it is so popular. It suits a clean modern patio and a traditional garden alike, and sits as well beside Victorian brickwork as beside a glass-fronted extension. Dense and hard-wearing, it handles foot traffic, garden furniture and freeze-thaw winters.
Silver when dry, blue when wet. Rain deepens the colour to a charcoal or blue grey, and it returns to its original shade once dry.

What goes with Kandla Grey
It works best in cool, clean palettes. Real gardens laid with Kandla Grey:
White walls
Bright, clean and minimal.
Timber
Adds warmth to a cool patio.

Finishes
Six finishes, one stone
Riven is the finish we stock in the UK and the most popular for gardens. Ask the team about the other finishes for larger projects. Smooth sawn faces can feel slippery when wet, so take care near pools and steps.

Laying

- Pull slabs from several pallets at once and mix them as you lay, for an even blend.
- Keep joints even and fill with a suitable jointing compound.
Care
- Seal after installation to protect against leaf tannins and stains.
- Sweep regularly and wash with mild soapy water and a soft brush.
- Avoid acid-based cleaners and strong bleach.
