I have a table with a white marble top that is left outside all year. Over a few years the surface has weathered and become rough. I would like to smooth it and possibly protect it (too heavy to move indoors).
My first thought was to use very fine wet and dry emery paper on a flat board with water lubricant. Is there some better way?
I have no idea what to use to protect it, nor even if it a good idea. I know I could use a varnish of some kind but this would create a different surface and change the colour. Has anyone used a protective coating that he or she can recommend?
