"Granite" is used as a generic term in the stone industry to describe igneous rocks composed of visible grains that appear like speckles in the rock. Some rock labled as granite in the industry are not “true” granites but basalts, gneisses, etc. Igneous rock begins as molten material or magma rising from the earth's core. As it comes into contact with other rock at or near the earth's surface and cools, granite will develop its unique appearance, character and nuances. Most granites withstand wear and exposure well due to the hardness of its many minerals. It is the most durable natural stone. If damaged or not cared for properly, granite is difficult to repair.
Even though granite many be naturally repel water and some caustic liquids, oils can still penetrate and cause discoloration or staining. Granite should be sealed with impregnating sealers. These sealers help repel liquids and oils, and maintain the stone’s health and beauty. With high grade sealers, Granite needs maintenance every 2 - 4 years.
