If you enjoy setting the baseline for interior and exterior designs, then set yourself up for this line of work. As a Terrazzo, Tile and Marble Setter, you will cover interior and exterior walls and floors with terrazzo, tile, and marble. You will use hand tools, lay mosaic tiles, remove and replace cracked or damaged tiles, and mechanically install natural stone on walls. People who love granite counter tops will also love what you can do to their kitchens.
