Granite Facts, Myths, & Care

  • Granite is difficult to maintain: Granite, because of its hardness and 'inertness' (means doesn't react with other materials such as acids), is an easily maintainable surface. For years granite has been used as an external cladding surface in commercial buildings because of its ability to withstand nature's elements and retain its original beauty.


  • Granite will stain and needs re-sealing often: Granite is exceptionally stain resistant, more so than many synthetic materials, including laminates and solid surface plastics such as Corian. There are certain granites that are more susceptible to staining and may require re-sealing once every one to two years. However, most granites will not require re-sealing for years, depending upon the care given when cleaning. If you use a mild soap and water instead of a harsh chemical product to clean the surface of the granite it can last for years without needing to be resealed. You can check the integrity of the sealer by puddling a small amount of water on the surface of the granite and letting it sit for 30-40 minutes. If a dark halo forms around the outside of the puddle this indicates the sealer is breaking down and needs to be renewed. You can re-seal the granite surface yourself and the process is easy, quick and inexpensive. If your granite is not sealed and you get an stain these can be removed.


  • Granite Harbors Bacteria: The Center for Disease Control confirms that there is absolutely no evidence of granite harboring bacteria or of anyone getting sick from bacteria in granite. Additionally, the National Institute for Occupational Safety & Health gives granite a clean bill of health. Granite is not more or less sanitary than any other surface. You may clean the surface of the granite like you would any other surface, however, the less harsh the chemical, the longer the sealer will last. Using an anti-bacterial soap will clean the surface and allow the sealer to last much longer.


  • Granite will lose its shine: Granite is an extremely dense substance in which normal household activities will not introduce a sufficient enough abrasion to the surface of granite to dull it. If it should lose some of its luster you may renew it by using a car wax applied in a thin coat, letting dry, removing with #0000 steel wool, and drying with a soft cloth. Dark stones require a black wax.


  • Heat will Crack Granite: Granite is able to withstand exceptionally high levels of heat up to 1000 degrees farenheit. This will allow you to move dishes straight from your oven or pots and pans directly from the stove onto the countertop without a problem.


  • Granite cannot be repaired: Granite does not break easily, however, should it crack or chip it can be repaired. If it chips you can repair it by using 'super glue' and a razor blade to level it off. Larger repairs or cracks require a stone specialist who will use colored epoxy.


  • Granite is too heavy for my cabinets: Most cabinet boxes, unless damaged by water or broken, can support loads of two to three times the weight of the granite


  • Granite is dangerous because of radon emission: Radon is a naturally occurring event, due to the breakdown of radioactive materials in the earth's crust. Granite has been proven to have less radon emission than most soils under houses. Radon also has a "half-life" of three days, which means that every three days the amount of radon would be one-half the level it was three days earlier.
