Surface Finish Options

• Polished – High gloss, enhances black depth and shine
• Honed – Matte, soft finish ideal for interiors
• Flamed – Rough texture for slip resistance (good for exteriors)
• Bush Hammered – Granular anti-slip texture
• Sandblasted – Slightly rough, uniform texture
• Leathered – Satin feel with slight undulations and character

Maintenance Tips

• Routine Cleaning: Mild soap and water; avoid harsh chemicals
• Sealing: Periodic sealing recommended for honed or flamed finishes; polished surfaces may require less frequent sealing
• Stain Resistance: Very good with proper sealing
• Scratch Resistance: High due to its hardness
