Water-repellent and oil-repellent nanotechnology product, suitable for the protection of marbles, granites, and other materials with extremely low absorbency on vertical or horizontal surfaces, in both outdoor and indoor spaces. The nanoparticles contained in its composition easily and deeply penetrate the surfaces, making them waterproof, thus protecting them from any damage that could be caused by moisture, water, and ice. At the same time, they make the surfaces resistant to common household stains, soot, nicotine, and atmospheric pollutants, making cleaning remarkably easy without the use of strong cleaners. NANO PROOF MARMO DS-275 does not create a surface film, does not shine, does not peel, and does not yellow, preserving the natural beauty and texture of the surfaces. Resistant to ultraviolet solar radiation, constant moisture, and frost. It shields the surfaces and prevents their discoloration. Odorless, water-based, user-friendly, and environmentally friendly.
