How does marble compare to granite in terms of slip resistance for wet outdoor seating?

When selecting natural stone for wet outdoor seating areas, slip resistance is a critical factor. Marble, while elegant, tends to be smoother and more polished, making it less slip-resistant when wet compared to granite. Granite, with its naturally textured surface and higher coefficient of friction, generally provides better traction in damp conditions. Additionally, granite's durability and resistance to weathering make it a safer and more practical choice for outdoor use. For optimal safety, consider honed or textured finishes on either stone to enhance slip resistance further. Always prioritize functionality alongside aesthetics for outdoor installations.
