How does the floor become so shiny?

Just as in the traditional polished stone applications applied to marble and granite, the surface of the concrete floor is ground using progressively finer grits to smooth and seal the surface. Instead of having a pitted surface that refracts light, the light reflects from off of the floor – THAT is what creates the shine of the surface. It is not a product, or sealer that makes the floor shine. It is the concrete itself reflecting light.
