Stone Care
Natural stone is a very popular material choice amongst the construction/design industry. Although Natural Stone can cost more than other materials, it is the most cost-effective investment choice due to its durability and longevity. “Even the most beautiful and well-installed natural stone will be subject to general wear and tear from people, pets, and objects. Maintaining the stone should be a top priority. “usenaturalstone.org””
In order to provide your stone with the proper care and maintenance, you must Know Your Stone. Each stone has its own unique features and characteristics and therefore will respond differently to cleaning products. The basic geological classification of Natural Stones is Metamorphic, Sedimentary, and Igneous. These three classifications are categorized under Calcareous and Siliceous. Calcareous Stones like limestone, travertine and marble have a high level of calcium carbonate and are sensitive to acids. Siliceous Stones like granite, quartzite, sandstone, and soapstone have a high percentage of silica and are tougher and more durable. It is important to use the right product and process for the type of stone and specific issue you are addressing.
To seal or not to seal? Considering Natural Stone porous characteristics, it is highly recommended to use a sealant for all Natural Stone surfaces. A sealer will help protect your Natural Stone against unwanted stains as well as prevent damage to the stone from elements that can cause erosion. How often? This is determined by the amount of traffic your stone will endure. High traffic areas take on more wear and tear and therefore is recommended to be re-sealed annually. Whereas low traffic areas are suggested to be re-sealed every 18 months to 3-5 years, depending on your own personal use.
There are two types of Natural Stone sealants, Topical and Penetrating. When choosing which sealant is best for your Natural Stone you need to know the stone characteristics, the finishes on the stone, the location, and usage. Topical sealers provide a thin layer of protection over the surface of the stone. This is meant to polish and protect the surface of porous stones against water and oil. Topical sealers are known to alter the look of the stone, often darkening the color of the stone. Penetrating sealers work below the stone surface by absorbing into the Natural Stone, depositing solid particles in the pores of the stone. This helps restrict water, oil, and dirt from entering the stone. Penetrating sealers do not offer any protection to the surface of the stone.
