Tenax Hydrex Impregnator Sealer for Marble, Granite & Stone – 1/4 Liter

Protect Stone Surfaces with Tenax Hydrex Impregnator & Sealer

Tenax Hydrex is a mineral-based impregnating sealer designed for marble, granite, and a wide range of natural stone. It blocks the entry of liquids while letting the stone breathe, helping maintain a natural feel and appearance over time. The formula dries invisible, so the look of a polished or honed surface stays true to life before and after sealing.

Because the finish remains invisible and does not alter color or gloss, you can seal stone surfaces in kitchens, baths, foyers, countertops, and outdoor projects without changing how they look under light or shade.

Key benefits

• Breathable protection that resists staining while preserving stone porosity
• Oil- and water-repellent barrier that activates within 24 hours
• Invisible finish on polished, honed, or smooth textures
• Suitable for indoor and outdoor applications on marble, granite, and other stones
• Fast drying and simple recoat with a second coat after a 5-minute wait

How to apply and what to expect

• Prepare a clean, dry surface free of dust and cleaners
• Apply a thin coat evenly across the area
• Wait 5 minutes, then apply a second coat for extra protection
• Allow to dry completely before use; the surface will stay optically true
• Coverage is approximately 160–180 sq ft per quart (about 15–17 m2)

Real-life scenarios include sealing kitchen countertops, outdoor steps, shower surrounds, and fireplace mantels where a breathable barrier helps liquids bead up and wipe away without altering the stone’s natural color. The product is suitable for surfaces with different textures, from polished to honed, and works well on indoor and outdoor installations.

Care and safety

Handle as a HazMat product and follow local safety guidelines. Use in well-ventilated areas and store away from heat sources. The surface may be ready for use after the indicated drying and recoating steps.
