If your countertop is uneven or not level, you will have to scribe and cut the first row of tiles to achieve a level and straight installation.
The objective of this installation process is to cut a small amount of Aspect Stone material off of the bottom of each tile in the bottom row so that it follows the uneven countertop. At the same time, the tops of each tile must be straight and level. With a straight and level countertop, the first row guide line is typically snapped at the highest point of the countertop. In this case, however, we will snap our guide line at the lowest point of the countertop.
