Aug 25, 2022 · The article then explains how, modifying the traditional 50% offset used in a brick pattern (see diagram above) to a maximum of 33% - which doesn't affect the look of the pattern - when installing tile 18" or larger, will manage lippage. "The above 1/3 offset is now the prevailing recommendation from the Tile Council of North America 2011 for ...

- 33% offset recommendations for LFT. ANSI also provides the standards which guide the installation of ceramic tile (which includes porcelain) when the specified tile is 15″ or longer on any one side (popularly known as large-format tile or LFT).
- Straight stack. A tile pattern of square or rectangular tile that has grout joints aligning in both the north/south and east/west directions is known as a straight stack or stack bond.
- The 33% offset reverse. Rather than having the two low points adjacent to the high point as in a 50% offset, the tile in row one is moved to the one third point (33%) of the tile in row two.
- The 33% offset stairstep. In this 33% offset stairstep pattern, rather than switching back and forth as in the 33% reverse, it continues in one direction forming a stairstep appearance.
Nov 6, 2020 · If an offset more than 33% is desired (such as a 50% offset), the specifier and owner must approve a mock-up and agree to the lippage that may result from this type of pattern being installed. The reason for this is that some tiles have what is called warpage as part of their manufacturing process. Warpage is when the tile is bowed in the middle.
Jan 14, 2020 · The woodgrain plank was a 6”x 36” calibrated (not rectified) tile with a 6” (16.6%) offset, which can help eliminate lippage. The grout joint about a 1/16” which is less than the required joint size of 3/16” for a calibrated tile under ANSI A108.02 – 4.3.8.1. The lippage was just over 1/16” which is double the allowable 1/32”.

Mar 22, 2024 · For Pressed Floor and Porcelain Tile, all tile sizes, with a 1/16” to less than ¼" grout joint, the allowable lippage is 1/32” plus the allowable lippage of the tile as permitted in ANSI A137.1. Given the tile industry standards and best practices that support the proper installation of tile, one would think and expect a stellar installation.

Jul 30, 2015 · For this reason, ANSI A108.02 says for running-bond patterns (i.e. staggered or offset) using tiles where any side is greater than 380 mm (15 in.), the grout joint size must be an average of at least 3.2 mm (1⁄8 in.) wide for rectified tiles, and a minimum of 4.8 mm (3⁄16 in.) for calibrated tiles.
