Where does Sandstone Tiles come from?

Sandstone Tiles are a sedimentary rock group which is mostly made up of tiny grains of quartz. Most sandstone is formed in oceans, lakes and rivers where tiny bits of rock and dirt settle to the bottom.

Year after year, these layers of sand get buried under tons of more sand and dirt until it is turned into solid rock. Sandstone can be found in many colors.

Sandstone does not split easily into sheets of equal size and must be mined with care. The rock may shatter if explosives are used.

We recommend you seal your Sandstone with our range of Lithofin sealers Stone Care Products, it will stop dampness coming into and prevent staining.

Where can you use Sandstone Tiles?

Sandstone Tiles was traditionally used in sculpture and architecture, suitable as a building stone or ornamental stone.

The durability and attraction of Sandstone as a natural stone is just unmatchable. Sandstone is a beautiful building material for both flooring and walls in wet and dry areas of your home.

Sandstone Tiles ensure a unique and exciting look for your entire home along with being enduring for several generations.

For use on bathroom walls the ideal thickness is 12mm. If used outdoors as a paver 30mm thickness is recommended unless laid on a concrete base where a thinner Sandstone tile may be used.

Common Sizes for Sandstone Tiles

Sandstone tiles come in a variety of sizes and thickness. Most common sizes for indoor flooring, walls and paving are 300mm x 300mm, 400mm x 400mm, 500mm x 500mm, 600mm x 600mm, 600mm x 300mm, 600mm x 400mm.

Larger and smaller tiles are available usually as a special order. Thickness will increase generally from 12mm for wall tiles, upto 20mm for floor tiles and 30mm for pavers.

Common Surface Finishes for Sandstone Tiles

Honed: The surface of the tile is sanded to create a matte finish

Brushed: Wire brushing give the surface a worn, textured surface

Sand Blasted: Is a textured surface with a slightly glossy finish

Sawn or Natural: Natural surface is created by using a gang saw.

Choosing the right Sandstone Tile for your Project

Sandstone Tiles are available in a variety of colours and banding. Common shades available are white, gray, mint white, yellow, brown and banded

After colour variation another point to consider is the availability of distinct finishes. Sandstone is available in brushed, honed finishing, bush hammered, natural and sandblasted finishes. Each finish is very distinct.

The application areas of Sandstone tiles & Sandstone Pavers at home are wide. The very popular use of this tile is in outdoor areas, paths and pool surrounds and coping. Sandstone tiles will last for many decades.

Installation of Natural Sandstone Tiles

Every Sandstone Tiles are unique as they are a product of nature. As such, Rosa Stone recommends the blending of Sandstone tiles.

The tiles should be set aside to dry prior to tiling to check for unsightly tiles and colour variation. If you have selected a large number of tiles you may want to mix them up to separate any batch variations.

Once you have installed the tiles we can not accept any responsibility for damaged tiles or wrong tiles being fitted.

Quite often the Sandstone tiles appear darker than the samples you observed. This is generally because the tiles are wet, and only appear darker. All natural stone tiles are produced in a wet environment using a lot of water.

You will need to dry your tiles out before tiling to make sure they are the same shading to obtain the best blending.

Some natural stone tiles have little chips due to the packaging and movement during transit. This is normal and is accepted as normal in the tile industry. Always inspect and shuffle your tiles prior to tiling to get the best results.

Sandstone tiles & pavers should be laid by a Floor & Wall Tiling Services Specialist.

Physical Properties of Sandstone Tiles

Physically, they are very Hard, Compact, Fine grained, equi-granular homogeneous rocks of sedimentary nature (Sandstone)

Color Minor colour tonal variations exist but within the tolerance limit.
Hardness 6.5 to 7 on Moh's Scale
Density 2.3 to 2.4 Kg/cm3
Compressive Strength 90-140 N/mm2
Modulus of Rupture 16-40 N/mm2
Water Absorption 1.0 - 1.2 %
Porosity Low to very low.
Weather Impact Resistant

Chemical Properties of Sandstone Tiles

Chemically they are very resistant Mono-Mineralic rocks, principally composed of silica. The other minor constituents vary from origin to origin.
SiO2 95-97%
Iron (Fe2O3) 0.5%-1.5%
Alumina (Al2O3) 1 to 1.5%
Soda (Na2O) & Potash (Kro) Less then 1%
Lime (CaO) Less then 0.5%
Magnesia (MgO) Less then 0.5%
Loss On Ignition (LOI) Less then 0.5%

They are highly resistant to acids, alkalies and thermal impact. Insolubility in acids and alkalies is about 97%.

Teakwood and Rainbow sandstones differ from above physical properties

Hardness 6 to 6.5 on Moh's Scale
Density 2.07 to 2.11 Kg/cm3
Compressive Strength 41 to 63 N/mm2
Modulus of Rupture 7-11 N/mm2
Water Absorption 8.0 - 11 %
Porosity Comparatively Porous
Weather Impact Resistant
