Stonemark™ granite countertops are unique because they feature the ultimate stain-resistance technology, PermaShield™. Unlike sealers, which need to be applied liberally across the entire countertop surface, the PermaShield™ process covers microscopic staining paths below the surface of granite. These paths are infused with molecular technology that causes them to adopt water and oil-repelling properties. Due to this revolutionary process, PermaShield™ does not affect or alter the surface of granite, leaving no added color or coating. No other granite countertop provides the same combination of beauty and performance that comes with the Stonemark™ name and the PermaShield™ process.
