Tenax Proseal Sealer 250 mL – Stone Sealer for Granite and More

Tenax Proseal Sealer 250 mL is a solvent-based protection solution for natural stone, developed by Tenax in Italy. In independent tests, the formula demonstrated strong value and reliable performance across a broad range of stones, including granite (even exotic varieties), as well as limestone, sandstone, terrazzo, concrete, and engineered stone. The sealer is intended to be applied to dry, clean surfaces, with care taken to avoid moisture, dust, or dirt that could influence the finish. Whether you’re refreshing a showroom display or safeguarding a maintenance project, Proseal provides a practical option for stone care.

When applied properly, you can expect a uniform, satin-like finish that helps resist staining. The product supports flexible application methods—brush, sponge, cloth, or spray gun—so you can tailor coverage to the size and shape of the surface. Start with a light coat, spread evenly, then buff the surface with a clean cloth to remove any residue. Avoid leaving a sticky film by removing excess immediately. For increased uniformity, repeat the treatment after about 10–15 minutes. The anti-stain effect is designed to develop within 24 hours after the treatment is completed.

How to apply

• Ensure the surface is dry and clean before application.
• Apply a conservative quantity that the material can absorb; spread evenly.
• After a short dwell, buff the surface with a clean cloth to remove excess.
• Avoid leaving any film; wipe off any excess immediately.
• For best results, repeat the treatment after 10–15 minutes.
• Do not walk on floor surfaces until the 24-hour anti-stain period has passed.

For commercial and industrial environments, Proseal is positioned as a practical option that supports protective maintenance without guaranteeing specific outcomes. It is designed to work across a variety of stone types, and the 24-hour maturation window provides a clear reference for scheduling cleaning or installation activities. Note that shipments are limited to the continental United States.
