The trick to marble is to match the marbling – and that’s usually done by the stone-cutter or quarry.
Waterfall edge countertops are tricky. You need a beveled cut, to begin with. The mitered surfaces get cuts in them, and an epoxy is mixed as a bonding agent.
After the epoxy hardens (a few minutes) a series of increasingly-fine wet-sanding heads are used to sand down the edge.
