Questions and Answers
Q & A 1
Question: How thick is my Granite, Marble or engineered kitchen benchtop and how much does it weigh?
Answer: Most of the kitchen and bathroom benchtops in Perth are usually made from 20mm thick material and to make the 40mm thick edge they simply double up the material on the edge or overhang.
As a general rule 20mm thick granite will weigh approx 60kg per square metre.
Engineered stone will weigh approx 55kg per square metre.
Marble will weigh approx 50kg per square metre.
Q & A 2
Question: How much overhang can I have on my island top or breakfast bar bench?
Answer: As a general rule 300mm is the maximum overhang that you can have; anything over this will require a steel / timber frame or corbels to help support the top.
Q & A 3
Question: Is a high range material better quality than a low range material and what affects the cost?
Answer: No the main difference is what it has cost me to get it to you. Some material has easy access and very close to shipping ports, some are in the middle of no-where and our trucking costs are higher. Also the extraction costs for some mines are more than others and when materials are being processed the recovery or yield from the block can vary adding to, and lifting, the price. Also if there is more than one mine or owner of a colour, competition takes over and we can barter for the best price.(Supply and demand.)
Q & A 4
Question: Do I have to seal my granite top?
Answer: Not all materials need to be sealed as they all have different absorbency rates and porosity.The lighter the colour the more chance you need to seal.
The best way to find out if your top needs to be sealed is to put a little water on it, wait for 5 minutes and, if the colour changes, it may need to be sealed or re-sealed.
Colours like Jet Black or Galaxy Black are a waste of time to seal but colours like Kashmir White could definitely benefit from some sealer.
If you are not sure ask your stonemason or us.
Q & A 5
Question: Can I seal my benchtop or tiles myself or do I need to get in a professional?
Answer: Yes, you can seal your investment yourself. A good quality sealer like MB Stone Care (MB4) will do the job, as it is a great all-rounder.
Please follow the instructions on the bottle but the rule is, basically, clean your tops or surface as you don't want to seal in any stains; wipe on the sealer and allow to soak in and then wipe off any residue. Depending on the porosity of the material, 1 or 2 coats may be needed. For newly laid tiles please allow 1 to 2 weeks to be totally dry before sealing
Q & A 6
Question: Can I put hot pots and pans onto my new top?
Answer: No! No-one has control over thermal expansion or shock. Natural granite will handle the heat changes better than engineered stone. Don't try it on engineered stone, it will crack, as the resin in the material moves a lot quicker. As a general rule, if you attempted to pick it up then please put it down on a trivet or the granite before you burn yourself. For engineered stone, try getting it to the sink. However, I always recommend using a hot mat. Why tempt fate as, if it does crack, its not easy to fix.
