Professional Marble Polishing | GFS Italy

Restoring Natural Brilliance

Marble is one of the most prized flooring materials in luxury hospitality, yet it is also one of the most vulnerable to wear. Foot traffic, furniture movement, improper cleaning and acidic spills gradually dull the surface, creating a hazy, lifeless appearance that diminishes the elegance of the space. Professional marble polishing restores the deep, reflective shine that makes marble floors extraordinary.

Our polishing process follows a multi-step diamond abrasive sequence. We begin with an assessment of the marble type, current condition and desired finish level. For heavily worn floors, we start with coarse diamond pads (50–100 grit) to remove the damaged top layer and level any lippage between tiles. We then progress through medium grits (200, 400, 800) to refine the surface, and finish with ultra-fine pads (1500, 3000, up to 10,000 grit) to achieve the final polish.

After diamond polishing, we apply a crystallization treatment using oxalic acid-based compounds. This process creates a chemical reaction with the calcium carbonate in the marble, forming a hard, glossy calcium oxalate layer on the surface. The result is a deep, glass-like shine with improved hardness and resistance to wear. Gloss meter readings typically reach 80–95 GU (gloss units) after our treatment.

For travertine and limestone, which are softer and more porous than marble, we adjust our technique accordingly. We use gentler abrasive sequences, fill voids with colour-matched resin where needed, and apply appropriate sealers to protect against staining while maintaining the stone’s natural breathability.

We work on floors of all sizes, from intimate boutique hotel lobbies to grand ballrooms spanning thousands of square metres. Our equipment includes planetary grinding machines (counter-rotating heads for flat, even results), edge grinders for perimeter work, and hand tools for intricate areas around columns, stairs and decorative inlays.
