Tenax Proseal Nano

Proseal Nano Quartzite Stone Sealer

Tenax Proseal Nano is a professional-grade solvent-based impregnating sealer specifically engineered for quartzite and other natural stone surfaces. Designed to penetrate deep into the micropores of stone, it provides long-lasting stain protection while preserving the stone's natural appearance and breathability. It is particularly effective on dense and polished quartzites that can be difficult to seal with conventional products.

Unlike topical coatings, Proseal Nano becomes part of the stone's pore structure without creating a visible film, making it an excellent choice for countertops, flooring, wall cladding, and exterior stone installations.

Key Features & Benefits

Deep Penetrating Protection

Proseal Nano penetrates deeply into stone microporosities to help resist staining from oils, dirt, moisture, and everyday contaminants while maintaining the natural beauty of the material.

Designed for Quartzite

Unlike many general-purpose sealers, Proseal Nano was developed specifically for quartzite surfaces, making it a popular choice among fabricators and stone professionals.
