With the advent of most service companies going “green” one of the interesting components of real stone restoration is that most work is done merely with honing\polishing pads made of diamonds embedded in a resin and a little bit of water to keep the slurry or dust down. There are other methods that are utilized in the polishing of marble that are considered to be faster especially among commercial service companies called vitrification that utilize acids and flurosilicates.In the eyes of most true stone restorationists, this not only destroys the stone but is considered a quick fix.For those of us that care in the business,(for the stone, your health and the environment) a true stone restoration professional can fix most problems of a stone surface with nothing more than the tools and water!
