Much of the beauty and versatility of installed tile lies in the ability to utilize patterns to create an interesting effect. Today, with the popularity of rectangular tiles, the pattern of choice has been the 50% offset or brick joint. While this pattern can be very attractive, it can also be frustrating when the inherent warpage on the long side of the tile causes lippage.
This lippage issue many times leaves the installer with a difficult if not impossible task, when a 50% offset with a credit card or 1/32” grout joint is specified. The problem occurs when the high point in the center of the long side of the tile is placed very tightly next to the two low point abutting tile ends.
