Tenax diamond brushes can be used on existing tools that are used everyday in fabrications shops. Airflex brushes remove the “softer” material in the stone to create a beautiful texture while enhancing the natural color in the stone. The Tenax Filiflex comes in 36, 46, and 60 grit. Made with many narrow bristles, the Tenax Filiflex removes material more aggressively and cuts deeper to create a nice antique look. The Tenax Airflex, which starts at 120 grit adds color and forms a beautiful soft antique look. Grits used to create a typical antique finish: Start with Filiflex 36, 46, and 60 grit. Then finish with Airflex 120, 220, and 300 grit. Higher grits are available to create a “caress,” or polished finish.
