Ultimate Guide on Which Cladding Stone is Right for You?

Published by Armstone, 13 February, 2020

With so many options available to you at the tip of your fingers, there are key factors to consider and take into account before locking in your selected material for your stone cladding to the walls.

It’s important to consider what type of cladding stone to use and where will be the appropriate place for that particular stone to be.

Not all-Natural stones claddings are suitable for all areas.

Here are the questions and answers of the 4 Important scenarios you need to be very cautious about:


1. Would the stone cladding be facing mostly towards the sun or is it under the shade, next to the damp area?

As you know any Natural stone is porous to some degree, some are hard-wearing like granite and others soft like Sandstone.

The issue you get with softer porous stones is the loss of its appearance: discolouration and mould attraction.

If the area is always under the shade and there is no direct sunlight on it for most of the day then maybe sandstone cladding is not the way to go. You should consider denser stones like granite cladding, quartz or even limestone cladding.

Unless you happen to live in an area where there are many old sandstone homes which tend to already look grey/aged, then go for it! The older the sandstone cladding gets the more it will complement the rest of your home.

2. Will there be direct or close water contact with your stone cladding?

Some natural stones are not suitable to use around swimming pool feature walls with close or direct contact with the pool water.

There are two reasons why:

Firstly, some natural stones like Slate or Mica-Schist Quartzite can leach iron out, which will contaminate the water (which is not good for the human body)

Secondly, we have come across certain projects where people have used sandstone cladding on a pool feature wall where the water runs of it.

Sandstone is extremely porous and vulnerable to salts and acids, a top reason we don’t recommend sandstone to be installed in any areas that may contain close contact to water, such as a pool or pool feature wall.

Chlorinated or saltwater will deteriorate the Sandstone cladding and on top of that headache, the crumbled sand will slowly get into the filter of the pool and this will create a failure of your pool filter.

3. Can you install cladding on a plaster wall?

There are some glues that are suitable to use for tiling (lightweight stone) on top of a plaster wall, however, you wouldn’t be able to stick stone cladding on the plaster wall. A plaster wall is a softer building material that wouldn’t take the weight of the heavy stones, such as stone cladding.

Natural Stone Claddings weight on average is between 90kg-180kg per m2, this is much too heavy to stick on a plaster wall.

4. How high is the wall? Would the cladding require mechanical fixing?

If the stone weight is not too heavy you may still be required to manually fix the cladding on the wall or use angles to rest the cladding on, after certain heights.

Usually, for walls up to 2 meters high, moisture-sensitive quick drying glue is sufficient enough. However after the 2m mark, every 800mm you would need to use the angles again. For example 2m then 2.8m then 3.6m etc

For heavy stones, such as sandstone cladding, large sizes, for example, 600×300 or more would require you to pin each piece one by one as the weight on each piece can be up to 40kg each.

If the cladding is for piers or columns, please consult with us directly to know which size and format will work best with your specific column size.


It is important to select the correct cladding for you and your home, the right stone cladding should complement your space, surrounds and budget but most importantly it should be the right type of material for the environment it will be used in.

It’s critical to take all factors into consideration before making your choice as dressing walls with stone can be a costly investment and ensuring its longevity is a sound decision.
