Surface Softening Treatment | GFS Italy

Smooth, Clean, Comfortable

Textured porcelain stoneware and structured natural stone are popular choices for hotel bathrooms, spa areas, pool decks and outdoor terraces because of their inherent slip resistance. However, their rough surface texture creates a significant maintenance challenge: dirt, grime, soap residue and mineral deposits become trapped in the micro-grooves and ridges of the surface, making thorough cleaning extremely difficult with standard mopping.

GFS surface softening treatment addresses this problem by selectively reducing the peak roughness of the texture while preserving its overall profile. We use calibrated diamond abrasive tools to gently round off the sharpest peaks on the surface, creating a smoother feel underfoot without eliminating the texture entirely. The result is a floor that retains its anti-slip properties (verified by pendulum testing) but is dramatically easier to clean and more comfortable to walk on barefoot.

The treatment is particularly valuable for textured porcelain tiles with a Ra (arithmetic mean roughness) value above 10 µm, where cleaning difficulty is most pronounced. After treatment, Ra values typically decrease by 30–50%, bringing the surface into a range that balances slip resistance with cleanability. We verify both metrics (COF and Ra) before and after treatment to ensure optimal results.

Surface softening is also beneficial for structured natural stone such as bush-hammered granite, flamed travertine and sandblasted limestone. These finishes, while architecturally attractive, can be abrasive on bare feet and difficult to maintain. Our treatment smooths the harshest peaks while preserving the characteristic texture of the stone.

The process is completed in a single session using floor-mounted grinding machines equipped with flexible diamond pads. No chemicals are used—the treatment is purely mechanical. The floor is ready for use immediately after treatment with no curing or drying time required.
