Marble floors can last for generations when properly cared for, but stone does tend to need more care than other tile materials. Because marble is porous, Tile Club recommends regularly sealing marble tiles to prevent stains from water, liquids, or ‘rust’ (caused by iron deposits that can surface over time). A little care and cleaning will ensure marbles like Calacatta Gold, Carrara, and white Thassos are beautiful for years.
