Care & Maintenance for Natural Stone

Stone's durability has been tested throughout the ages—in homes, commercial buildings, cathedrals, and even pyramids. Use the following care tips to ensure that your stone will not only last, but will stay beautiful.

Sealing Natural Stone
   
Sealing natural stone is a simple process that prevents staining and maintains stone's beauty. We recommend an impregnating sealer which penetrates the stone’s surface to protect it against moisture, dirt, and stains. Before sealing, a thorough cleaning is recommended to avoid sealing dirt and grease into the stone.

   
The life of the sealer will depend upon the type and finish of the stone, the area of application, and its exposure to wear. A piece of stone which is sealed with an impregnating sealer and put in a closet will stay sealed indefinitely. Impregnating sealers are preferred to topical sealers because they increase both the longevity and quality of the protection. Although sealer makes the stone less susceptible to staining, applying when it is unnecessary just wastes time, effort, and money. A simple test to determine if your stone needs to be resealed is to sprinkle it with water. If the water beads up tightly, then the stone has maintained its seal. If the water soaks in or darkens the stone, then allow the water to evaporate and reseal. Granite sealers can last up to 15 years, depending porousity and type of granite.  General recommendations for residential flooring is to seal once every 5-10 years.

Cleaning Natural Stone

A pH neutral cleaner will work for any type of natural stone. Be careful not to use bleach or abrasive products on any natural stone installation to prevent damage to the stone. Many name brand household cleaners are highly acidic and can cause damage to calcareous stones like marble, limestone, travertine and onyx, as well as the sealers protecting them.
