If you opt for a finish other than a polished finish, the surface porosity increases. The honed finish granite countertop is polished to a smooth surface but not enough to produce a reflective surface resulting in a more subtle, natural looking stone appearance. This finish will be more porous than polished.Resources. âGranite countertop Finishes from Wolf Granite.â Wolf Granite.olished Granite Is the Most Durable. Most granite countertops are polished then sealed making them nearly impermeable. Polishing the stone creates a flat, smooth surface that reduces the porosity making it more resistance to spills and stains. The addition of a top-coat sealer helps to strengthen its endurance.
