Tenax Hydrex Sealer

Tenax Hydrex Stone Sealer – Invisible Protection for Granite + Polished Stone

Tenax Hydrex is our best-selling granite sealer, trusted by professionals for its deep penetration and reliable protection. Formulated to block both water and oil from entering the micro-pores of stone surfaces, Hydrex helps prevent stains while maintaining the stone’s natural look and finish.

Perfect for use on polished granite, marble, and similar natural stones, this solvent-based penetrating sealer forms an invisible barrier that repels liquids without altering the color or texture of the material. Hydrex is ideal for premium stones like Carrara, Thassos, Trani, Botticino, and Crema Marfil, especially those with a polished finish that still require breathable protection.

Whether used indoors or outdoors, Tenax Hydrex protects stone while allowing it to breathe, preserving its original characteristics and long-term appearance. The product operates just below the surface of the stone, offering discreet yet effective defense against everyday spills and moisture.

Application is simple — apply to a clean, dry surface using a sponge or cloth until the material is fully saturated. Any excess must be buffed off immediately to avoid sticky residue. Reapplication after 10–15 minutes enhances performance, and treated floors should cure for 24 hours before foot traffic.

Each 1-liter bottle of Tenax Hydrex covers approximately 215–323 square feet, depending on the stone’s porosity. Shelf life is up to two years when stored between 65°F and 77°F away from heat and sunlight.

⚠️ Important Note on Marble: Tenax Hydrex does not protect against etching caused by acidic substances like wine, coffee, tomatoes, or citrus. For etch protection and restoration, use Tenax TeEtch or an approved etch remover.

When you need a clear, breathable stone sealer that provides long-lasting protection without changing the look of your surface, Tenax Hydrex is the professional’s top choice.
