Check out the reflectivity and clarity on this floor. One may be hard pressed to believe that less than 8 hours ago, it was a traffic worn, etch covered cause of tears for a well-intended home owner. The simple and unavoidable grinding of dust, dirt and hair underfoot, or the spills of such common household items as soda, coffee, tea, salad dressing will leave a permanent history etched into the floor. Accidentally dissolving the calcium carbonate marble floor surface makes it impossible for normal cleaners to remove the damage.
So which was safer? Worn matte or gloss finish.
Believe it or not, both are just as safe. While the material surface and finish can contribute to slip, the floor is going to require water, oil or dust, that is not affixed to the floor to allow your feet to slip.
