FS Nano Power Protector is a ready-to-use, solvent-based impregnator formulated to deliver high-performance protection for stone, tile, and grout surfaces. Designed specifically for low-porosity materials such as unglazed tile, grout, terracotta, and dense natural stones, it penetrates deep into the substrate to create an invisible subsurface shield that blocks the absorption of oils and liquids. The treatment rapidly absorbs into compact surfaces, offering long-lasting resistance against stains while preserving the original colour and appearance of the material. Its oil- and water-repellent finish provides outstanding stain defense without leaving any surface film, making it an effective solution for maintaining the natural aesthetics of treated surfaces.
