Tenax Proseal Impregnating Stone Sealer – 1 qt, Solvent-Based
Tenax Proseal Impregnating Stone Sealer – 1 qt, Solvent-Based
The Tenax Proseal Impregnating Stone Sealer is a 1 qt solvent-based penetrating sealer that protects granite, marble, quartzite, limestone, travertine, slate and other natural stone from oil and water-based stains without changing the color or leaving a film on the surface.
It is a stain sealer, not an etch guard: Tenax states that Proseal gives no anti-etch protection on marble, so wine, citrus, tomato and coffee will still mark a marble top. For dense quartzite that resists a standard impregnator, the Tenax Proseal Nano – 1 Quart, Solvent-based Nano Impregnating Sealer is the smaller-molecule version of the same line.

Frequently Asked Questions
How much does a quart cover?
Tenax publishes about 215 to 323 sq. ft. per liter depending on the porosity of the stone; a quart is a little under a liter, so plan on roughly 200 to 300 sq. ft.
How long before the counter can be used?
The sealer dries in 4 to 5 minutes for buffing and reaches full protection after 24 hours.
Will it stop etching on marble?
No. Tenax states that Proseal does not provide anti-etch protection; acids such as wine, citrus and coffee will still etch marble. It protects against staining, not etching.
Does it change the look of the stone?
No. It is an impregnator that penetrates below the surface and leaves no film, so the color and finish stay as they were.
How is it different from Proseal Nano?
Proseal Nano uses a smaller nano-particle carrier for very dense stone such as quartzite. Standard Proseal is the general natural-stone sealer in the line.
Is it food safe once cured?
Distributor listings describe the cured sealer as food safe; Tenax's own page does not state it, so treat a cured, buffed surface per Tenax's label instructions.
