Most natural stone is porous and some stone types, such as marble, are calcite based and are acid sensitive, which means they may become etched when coming in contact with acids. For porous stone you want to fill those tiny holes to protect it from staining agents being able to penetrate. For acid sensitive stone, you may require a protective barrier between not only staining agents, but acidic substances and your stone. Clay tiles and pavers require other types of sealers, and grout requires a different kind of sealer to inhibit stains.
The right kind of sealer is determined by several things, including the type of material, where it is located, and what you want the look to be. At Elite Stone And Tile Care be assured that we only use the very highest quality, professional sealing and protection products on the market today, and we are happy to consult with you on the type of protection you need for your natural stone or tile surfaces.
