Tenax Hydrex Natural Effect Sealer – 1 Quart, Penetrating Water and Oil Repellent
Tenax Hydrex Natural Effect Sealer – 1 Quart, Penetrating Water and Oil Repellent
The Tenax Hydrex Natural Effect Sealer is a penetrating, solvent-based impregnating sealer supplied in a 1 Quart container that blocks water and oil in the micro-porosity of the stone without changing its natural appearance.
Key Features
- Penetrating impregnator: it works inside the micro-porosity rather than forming a film on the surface, so the stone stays breathable.
- Water-repellent and oil-repellent, which is the pair of properties Tenax publishes for this product.
- Natural effect finish. Tenax's own qualifier for Hydrex is 'Natural Effect' - it is not a color enhancer and is not intended to darken the stone.
- Single 1 Quart container. Tenax publishes Hydrex in 250 ml, 1 Quart, 5 Liter, 55 Liter keg and 200 Liter.
- Tenax states Hydrex gives no anti-etch protection on marble; acid etching is a separate failure mode from staining and no impregnator prevents it.
Who Is This For?
Countertop fabricators and stone installers sealing granite, marble and other natural stone at the bench or on site, where the customer wants stain resistance without a change in color or sheen. The 1 Quart container is a per-job or per-week size for a shop that seals occasionally rather than continuously; a shop sealing every day buys the 5 Liter.
What This Is Not For
This is a natural-effect sealer, so it is the wrong product if the goal is to deepen color and grain - use the Tenax Ager Color-Enhancing Impregnating Sealer for that. It is also not the sealer Tenax formulates for quartzite; the Tenax Proseal Nano is the quartzite-specific impregnator in the same range. And it will not stop acid etching on marble, which no impregnating sealer does.
Frequently Asked Questions
Does Hydrex change the color of the stone?
Tenax Hydrex is published as a natural-effect sealer, meaning it is formulated to leave the stone's appearance unchanged rather than to enhance color. The Tenax product for deepening color and grain is Ager.
Does it protect marble from etching?
Tenax states that Hydrex gives no anti-etch protection on marble. An impregnating sealer resists staining by blocking absorption; etch marks are acid damage to the stone surface itself and are not prevented by sealing.
What sizes does Tenax make this in?
Tenax publishes Hydrex in 250 ml, 1 Quart, 5 Liter, a 55 Liter keg and a 200 Liter drum. This item is the 1 Quart container.
Is it water-based?
Tenax Hydrex is a solvent-based penetrating impregnating sealer. The 'petroleum based' wording carried by the old catalogue listing does not appear on any Tenax page and is not used here.
