Tenax Proseal Nano Stone Sealer, Quart

Tenax Proseal Nano is a solvent-based impregnating sealer designed for dense quartzite, polished granite, marble and other natural stone surfaces with low absorption. Its solvent carrier helps the formula penetrate tight pore structures that may resist standard water-based sealers.

Once absorbed, Proseal Nano helps protect stone from dirt and staining while preserving the material's natural breathability, color and appearance. The non-enhancing formula is suitable for polished and honed surfaces in indoor or outdoor applications.

Why Use a Solvent-Based Sealer on Dense Stone?

Dense natural stone can have a tight pore structure that prevents some water-based sealers from absorbing properly. Instead, the sealer may bead up or remain on the surface.

Tenax Proseal Nano uses a solvent-based carrier to move the protective formula into the micropores of dense materials. This makes it suitable for quartzite and polished stone surfaces that can be difficult to seal with conventional water-based products.

Application Instructions

1. Make sure the stone surface is clean and completely dry.
2. Apply Proseal Nano evenly with a brush, sponge, cloth or low-pressure spray.
3. Apply only the amount of sealer the material naturally absorbs.
4. Wipe away excess product with a clean cloth after a few seconds.
5. Apply a second coat 10 to 15 minutes after the first application.
6. Allow approximately 24 hours for full anti-stain protection to develop.
7. For flooring applications, wait 24 hours before allowing foot traffic.

Important: Before treating the entire surface, test Proseal Nano on a small, inconspicuous area. Keep the container tightly closed after use.

Coverage

One liter of Tenax Proseal Nano covers approximately 215 to 323 square feet. Actual coverage varies depending on the stone's porosity, absorption rate, finish and condition.

Dense polished stone may absorb less product, while more porous material may require additional sealer to achieve complete coverage.

Frequently Asked Questions

What is the difference between Proseal Nano and regular Tenax Proseal?

Proseal Nano is solvent based and designed for dense, low-absorption stone such as quartzite and polished granite. Regular Tenax Proseal is water based and is intended for more porous stone. When a water-based sealer beads up instead of absorbing, Proseal Nano may be the more suitable option.

Does Proseal Nano change the color of stone?

No. It is designed to protect the stone without darkening it, adding shine or changing its natural color.

Can Proseal Nano be used on quartzite countertops?

Yes. Quartzite is one of the primary materials for which Proseal Nano is designed.

How many coats should be applied?

Apply an even first coat, followed by a second application after 10 to 15 minutes. Use only the amount the stone absorbs and promptly wipe away excess product.

How long does Proseal Nano take to provide full protection?

Full anti-stain protection develops after approximately 24 hours. Flooring should remain free of foot traffic during this period.

Can it be used outdoors?

Yes. Proseal Nano is suitable for indoor and outdoor natural stone installations.
