Re-Polishing At The Seams -- Should I Or Should I Not?
Let's look at the reasons why a fabricator might need to contemplate surface polishing, re-grinding or otherwise changing the existing factory polish on a piece of stone. The first and probably most common reason is that a seam is just not looking good (for a variety of reasons) to the customer. Maybe the two pieces of stone that make the seam are bowed, and the seam really shows it. Maybe there's way too much lippage showing at the seam, because the two pieces of stone are not correctly aligned with one another. Or perhaps the installer was just having a bad day.
The procedure known as “surface re-polishing,†“re-grinding†or changing the factory polish on the face of any piece of stone, is an operation that should not be attempted by the beginner or even a novice fabricator. Once you start this process, there is no turning back.
