Choosing your Schist Style

The exciting thing about choosing schist is that there are so many style options. Here’s a step-by-step guide to help you to narrow down what’s best for you.


Wanaka Schist is well known for its amazing variation of greys and golden-brown tones. We work hard to blend the different colour bands to provide an interesting array of colours in every order, however we can also produce orders with a higher proportion of specified colours if you wish.

Walling stone

Stacking Stone

Our most popular colour selection, this mix has light to dark grey, blue-grey, charcoal and occasional natural browns.


Pure Grey

We select a range of grey tones that creates a deeper, less varied look.

Naturals Closeup

Natural Brown

We collect straight faced stone that is mostly brown with occasional grey and warm cream colours.

We can cut the stone to any width, but our most popular widths are 150mm or 180mm. The 150mm width is most suitable when transport is a significant factor, or where space is limited. The wider 180mm width allows for longer and taller pieces of stone which is particularly popular for the bagged style (see style guide).


The stacking style is determined by the amount of grout that remains visible. The stacking style has a dramatic effect on the finished appearance of the work, in some cases completely changing its character. Narrow joints can complement the look of the stone and provide a ‘solid’ appearance, while wider gaps can emphasise the individual stone elements.

Dry stacked


Stone is tightly stacked with no grout visible. This is a very popular style that harks back to ancient dry stone walls and showcases the stone. Genuine dry stacked walls contain no grout at all, however this is not possible when cladding a building, but the dry stacked style provides a very similar look.

10mm joint


Traditional finish for stacked stone walls with a regular 10mm gap grout gap between every stone both horizontally and vertically. Grout can be left flush with the stone or raked (recessed) to create a gap giving a more natural appearance.

Wide joint


A more rustic appearance where the joint (gap between stones) is widened to show more grout. This can allow the grout to become more of a feature with tints, different mixes of sand size and colour or white cement.



This is a popular contemporary look that originated from traditional stonework. A very wide gap is allowed between stones and filled with grout to achieve the desired finish. Grout can be altered with different coloured sand and cement. The stone can be partially covered or carefully left exposed resulting in distinctive finishes.

Decide if you like the mortar recessed or flush

The finishing touch given to the visible mortar is referred to as ‘pointing’.

Raked Schist


Recessed (or raked) stone has the mortar gently brushed out of the joints. This creates more shadow and texture in the wall.



Flush finishes have the mortar level with the stone or even partially covering the stone.

Decide on Mortar Colour

Where grout is visible, dyes and coloured sands can be used to create a wide range of mortar colours. Stonemasons will generally lay stone using standard mortar and then carefully mix batches of coloured mortar to point the wall.
Grout colours that complement the stone tend to create a more unified, ‘solid’ appearance, whereas contrasting grout colours can emphasises the individual stone elements and be used to ‘break-up’ the look of a solid surface.

Finally you should choose a Stonemason

We are proud to work closely with a range of superb stonemasons and are always happy to recommend quality stonemasons throughout New Zealand. The New Zealand Stonemason Association ( have a list of member stonemasons also. When choosing a stonemason ask to see examples of their previous work, preferably in the same style you have chosen.
