Plan for a layer of thinset 3/16-inch to 1/8-inch thick beneath your tile. A 3/16-inch layer of thinset will be enough for tiles with a smooth back to bond the tile to the floor or backer board. For natural tiles with an uneven surface on the back, you may need to spread a 1/8-inch layer of thinset during installation.
What happens if thinset is too thick?
A thick layer of thinset, like most adhesives, is apt to flex and crack leading to premature bonding failure. In addition to producing an uneven surface, applying too much thinset can create costly cleanup headaches and add unnecessary time to a project.

Using a U-notched trowel and embedding the tile into the thinset leaves you with a bed of thinset beneath the tile a little over 1/3 the size of the trowel teeth.
