Proseal is a sealer from Tenax for all types of natural stone. It protects granite, marble, stone, and slate surfaces from the risk of staining. It is ideal for granite kitchen tops marble bathrooms limestone floors slate floors and stone fireplaces. It can also be used on engineered stone and concrete. Proseal renders the stone surface repellent to water and oil based liquids and inhibits the penetration of these liquids into the surface of the material. The liquids remain on the surface and can be wiped off without staining.

It provides strong protection against all the usual things that stain untreated stone such as cooking oil butter grease sauce coffee cola wine and fruit juice. It does not form a film on the surface. It allows the stone to breathe naturally. It is also UV stable.


For all types of natural stone, engineered stone and concrete
Suitable for polished, honed, sandblast, and flamed surfaces
Water and oil repellent

Refer to Safety Data Sheet and Technical Data Sheet before use. A preliminary test in a small, hidden, area is recommended before the main application. Ensure the stone is fully clean and dry. Pour the liquid onto the area and allow it to penetrate the surface for around 15 – 20 minutes. Move the excess liquid around the material using a cloth, removing puddles and streaks, adding more sealer to dry spots. Remove all of the remaining sealer within 30 minutes using a dry cloth – do not allow the product to dry on the surface. Keep the surface dry for up to 24 hours, depending on the sealer used. Please refer to the Technical Data Sheet for specific guidance on the sealer you are using. Depending on the porosity of the surface and the application, a second treatment maybe required. Do not wait for the surface to dry in between these applications.


Please refer to the Safety Data Sheet before use. Keep away from heat and humidity. Keep away from direct sunlight. Use in a well ventilated area.
