The two common major types of natural stone used for countertops are granite and marble. Each natural stone requires very different care and maintenance needs. This fact comes as a complete surprise to many people. Both materials, however, do use a sealer to help protect the stone’s beautiful surface. Silver State Floor Restoration will share how often marble and granite should be resealed, and its care.
Properties of Granite
Granite is a mixture of feldspar and quartz crystals that was formed from magma below the earth’s surface. There are a number of elements that give granite its different colors. However, the very nature of granite makes it very strong. Granite is much more durable and is resistant to erosion, scratches and impact damages more than other natural stones. As it is naturally very strong, it still can stain and eventually wear down after enough abuses. Granite should be resealed every five years or longer, depending on its care. However, each case will vary.
Marble is a very beautiful natural stone that comes in a variety of colors. Most commonly it is white with black veins. Marble is a metamorphic rock which means they are rocks that are altered by heat. Marble is primarily limestone. For those who don’t know what limestone is, it’s a very soft rock. As beautiful as marble is, it is one of the weakest natural stones used inside homes and for countertops. Marble stone requires a need to be cleaned after each interaction, and it needs to be kept clean. Additionally, they require resealing far more frequently than other natural stone. It is recommended that you reseal marble at least once a year, if not twice a year depending on the quality of the sealer.
