Tenax Proseal is an ultra-premium impregnating stone sealer designed to provide long-lasting protection against oil, water, dirt, and common household stains while maintaining the natural appearance of stone surfaces. Its advanced penetrating formula deeply absorbs into the stone without creating a surface film, allowing the material to breathe while providing superior stain resistance. It is suitable for both residential and commercial applications indoors and outdoors.
Proseal is compatible with a wide variety of natural and engineered stone materials, making it one of the most versatile stone sealers available for fabricators, installers, contractors, and homeowners.

Thoroughly clean the stone surface.

Continue application until the surface stops absorbing the sealer.
After 4–5 minutes, buff away excess product with a clean cloth.
Apply a second coat after 10–15 minutes if necessary.
Allow 24 hours for full cure and stain protection.

Do not leave excess material on the surface as it may create streaking or haze.
