QUESTIONI recently added a granite splash back to my free standing sink, that I should have done in the first place. They measured and applied a 4" splash on the existing granite. When the installer came with the granite he noticed they had not finished both sides. He came back several hours later and installed it. The front side looks great smooth and shinny, but the other side looks paler and has more rough spots. Shouldn't both sides look the same? Is there anything I can do?
ANSWERAnswer - I will assume that when you say both sides of the 4" tall granite backsplash you are talking about the front side which you will see, and the back side that is bonded to the wall that you will not see.
The only sides of the granite backsplash that should be smooth and polished are the sides that are exposed after it is installed. That would be the front side, the top edge and one or both end edges.
The back side should not be smooth and polished. It should be slightly rough so that it will bond better to the wall substrate.
