How to Install Stack Stone and Ledgestone

Posted on

Stack stone and also ledgestone, instantly improve the appearance of any internal or external living area or landscape. They are some of the most popular materials to enhance a commercial property or a home’s architectural facade. Stack stone as well as ledgestone is made up of individually stacked pieces of different types of stone like marble, quartz, slate, travertine, sandstone, granite and stone resin. They come in various sizes but mostly they’re constructed into 150x600mm pieces.


These products can be applied to render, brickwork, besser blocks, villa board, fibre cement sheeting (fibro) and most other building substrates. However, it’s not recommended to apply these products to blue board as any board that is treated weakens in strength.  If you want to apply stack stone or ledgestone on to fibro or villa board, we recommend that the thickness of the board be at least 9mm, not the standard building thickness of 6mm.

Fixing Stack Stone or Ledgestone

When fixing stack stone or ledgestone up to 2 metres high, we recommend a good stone glue like SMP EVO or Uni Nova, along with the manufacturer’s corresponding enhancers/additives to strengthen the glue.  This allows for the heaviness of  the material.

However, when tiling more than 2 metres in height, it is then recommended to brace the product onto the substrate. Bracing is the application of stainless steel angles which are anchored into the substrate at equal intervals to support the weight of the product.


As with all stone, we recommend stack stone and ledgestone be sealed.

Most stack stone is suitable for both indoor and outdoor applications.  However, when stone is polished, we recommend using it indoors rather than outdoors. Like all polished products, if it is installed outdoors and comes in contact with direct sunlight, then over time it will eventually etch away at the polished surface.


Here at TFO, we do not sell stack stone or ledgestone corner pieces as we have such a high turnover of stock that we would end up with the corners being a different batch to the current stock in store. For that reason, when needing corner pieces, we recommend mitring the edges at a 45 degree angle at the time of installation.
