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.
