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. Indoor & Outdoor Use Suitable for both interior and exterior applications, including countertops, vanities, flooring, patios, outdoor kitchens, and decorative stone installations. Maintains Natural Appearance The impregnating formula protects without creating a surface coating, preserving the stone's natural color, texture, and breathability. Simplifies Maintenance Sealed surfaces are easier to clean and maintain while helping reduce absorption of common staining agents. Compatible Surfaces Tenax Proseal Nano is suitable for: Quartzite Granite Marble Limestone Travertine Sandstone Slate Onyx Concrete Terracotta Agglomerates and engineered stone surfaces Applications Quartzite Countertops One of the most common uses for Proseal Nano is protecting quartzite kitchen and bathroom countertops from oils, water, food spills, and everyday contaminants. Natural Stone Flooring Provides protection for polished and honed stone floors in residential and commercial environments. Outdoor Stone Installations Suitable for patios, outdoor kitchens, landscape stone, and other exterior applications where moisture resistance is important. Instructions Surface Preparation Surface must be clean and completely dry. Remove dirt, waxes, residues, and contaminants. Test in an inconspicuous area before full application. Application Apply evenly using a brush, sponge, cloth, or low-pressure sprayer. Allow the sealer to penetrate the surface. Remove excess material after approximately 4–5 minutes. Apply a second coat after 10–15 minutes if necessary. Allow 24 hours for full stain protection to develop. Coverage Approximate coverage: 215–323 square feet per liter Actual coverage will vary based on stone porosity, finish, and application method.
