When Tiling a project, I always end up with a very slight fluctuation in finish height from one Tiling Section to the next. It may only be a difference of .002 to .005 in. But it is enough to detect and I do not want it. I have used a Dremel to attempt to blend in this slight difference, however I am still not fully satisfied with that result. What does everybody else use to blend in those differences? If you are using a Dremel or similar tool, what type of attachment are you using? Or is it just a simple attempt of Elbow and Sandpaper? Thanks for any input you may have.
