There is a lot of misinformation regarding if and how often granite countertops need to be sealed. A basic internet search will result in a variety of answers, stating granite should be re-sealed from twice a year to once every couple of years.
According to the Marble Institute of America, most granite countertops do not need to be sealed; however, sealing will help the stone resist dirt and spills that can lead to etching and staining. Granite is a naturally moisture-resistant material; however, since it is also porous, sealants will help block liquids from seeping into the stone. You can tell that a granite countertop has been properly sealed when water and oil-based liquids will bead up on the surface.
