How to care for your Indonesian sandstone

How much do you know about Indonesian sandstone?

Importing natural stone for use in a home isn't just a way to bring resort-level luxury to a private residence – it's a way to enhance an investment. Using Indonesian sandstone, whether outdoors or indoors, instils a level of decadence that can add a lot of value to a home – that's why architects, designers and homeowners alike have been bringing it into Australia for years.

To get the most out of imported stone, proper care and maintenance is an absolute must. Here's how Australians can ensure their Indonesian sandstone has as much longevity as possible.

1) Understand its composition

If you don't know the makeup of your stone, how can you properly maintain it?

If you don't know the makeup of your stone, how can you properly maintain it? Without this knowledge, your stone can erode, or you may end up cleaning it with products that actually cause it more harm. 

Sandstone is sedimentary, and is always siliceous – composed of silicates. For most sandstones, this means they have a high component of quartz and feldspar – any more than 25 per cent is called arkose, while sandstone with more than 90 per cent feldspar is called quartzose.

This means sandstone can be very soft – often too soft for residential or commercial use. Harder versions are ideal for bringing an earthy, worn feel to your outdoor or indoor decorating. As the Australian Stone Advisory Association points out, siliceous stones are generally resistant to acid, which bodes well for ongoing maintenance.

However, they still recommend avoiding acidic cleaners as sandstone can still contain minerals that will react poorly to these. 

2) Understand its application

Indonesian sandstone from Baumart is incredibly versatile. It can be used as tiling for outdoor areas, fencing and walls, cladding or general paving – even for feature walls when space permits. You can see famous applications of sandstone right across the country: in the Adelaide Railway Station; parts of Melbourne's Federation Square; and the walls of the Sydney Town Hall.

While hard enough for this use, its sedimentary nature means Indonesian sandstone can be finished in a number of ways: sawn cut, natural split face, honed or line chiselled. This variety has seen Indonesian sandstone remain popular among designers and builders for centuries. 

3) Understand its preservation

As with most natural stone products, you should clean your Indonesian sandstone with chemicals specifically designed for natural stone, otherwise you can end up eroding it faster than normal. In the absence of these, you may wish to focus solely on pH neutral cleaning products. Where appropriate, penetrating or impregnating sealers can help to preserve sandstone, which can be quite porous over time.

Also use caution with scouring cleaning products, as these can permanently mark your sandstone's surface. Make sure to speak to the team at Baumart for more specific advice on the best way to preserve your Indonesian sandstone.
