Granite is one of the hardest materials on earth composed primarily of quartz, feldspar and mica. The other minerals present in the stone give granite its unique colour, texture and pattern. It is resistant to scratches, acids, stains and heat. It is long-lasting, durable and available in a wide variety of colours, textures and unique crystal patterns that create a warm and inviting environment for your kitchen or bathroom.
Quartz surfaces consist of up to 93 per cent quartz which is stronger than natural stone and one of nature’s hardest minerals. Quartz surfaces are resistant to stains, scratches, cracks, heat and common household chemicals. Quartz surfaces retain the cool, tactile qualities of natural stone, while offering almost unlimited design possibilities.
The grades given to granite and quartz are for pricing purposes only and do not reflect the quality of the stone. Often we are asked to price a granite benchtop where the customer has not yet specified the stone.
In this instance we provide a quotation on a range of granites from categories A-F (category A being the lowest price and category F being the highest). Then when the customer selects their stone all they need to do is match the category given to the stone with the quotation provided earlier.
Granite and Quartz are the most versatile stones to work with. Granite and Quartz can be used anywhere indoors or outdoors. The choice or either product generally comes down to colour.
The density and weight of granite is variable. On average, 1 square metre of granite that is 3cm thick weighs approximately 100 kilograms.
As long as your kitchen cabinets are level and are secured to the wall and floor, they will adequately support granite benchtops.
Your natural stone benchtops have been treated with a sealer matched to the type of stone and type of surface you have. In most cases this will not need to be done again. However, this is not an impervious coating and care is required to keep your top from damage. For a deep clean use hot water with a mild ph neutral soap, then dry with towels. We recommend using Lithofin Easy Clean for use on benchtops in all materials. This is available from any branch of Tile Warehouse, Tile Depot or CDK Stone in Rosedale.

However, you may consider the use of a chopping board to protect your kitchen knives. Cutting directly on the surface of a granite benchtop will blunt your knives.
Your granite benchtop may require sealing. Otherwise, cleaning the benchtop with soap and water should suffice. Don't use acidic or abrasive cleaners that will dull the finish over time.
Reasonable damage such as small cracks or chips can be repaired. However, be aware to always try and save the chipped piece of stone.
A study was made to measure the bacteria-resistance of six common benchtop materials.
The study involved contaminating each surface with E. coli. The surfaces were washed and rinsed with soap and water and then sanitised with a vinegar and water solution. The results revealed that Stainless Steel, Granite and Quartz are clearly a hygienic form of benchtop.
In most cases overhang should not exceed 350mm beyond the supported area.
There are few things that will scratch granite and quartz:
diamonds
another piece of granite
hardened steel
If you want to scratch the granite you could, such as by driving a knife into the granite with force and dragging it along the surface. However, under normal conditions you should not scratch it.
By contrast, marbles and limestones are very easy to scratch.
