- 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.

Jul 30, 2012 · Many tile manufacturers now recommend that their products be installed with the 33% offset which further supports tile mechanic’s need to install a tile pattern that will be satisfactory.
However, not all ANSI-compliant tiles can be used with a 50% offset. Even fewer can be used with a 50% offset and a narrow grout joint, and none should be used under these circumstances if installed with wall-wash lighting.

For starters, we need to clear up a common misunderstanding. 12×24 tiles are not twelve inches wide nor are they twenty-four inches long. In fact, the vast majority of “12×24” tiles are measured using the metric system, which almost the whole rest of the world uses. Therefore, the metric measurements are 30cm x 60cm. This converts to 11 13/16ths x ...
All large format tiles (large hexagon tileare an exception) can be installed in a straight-lay pattern where the edges all match up. However, with rectangular tiles, such as 12×24’s, it’s quite common to install them in an offset pattern. But a word of caution: tile industry standards, and many manufacturers, recommend against a 50% offset pattern....
There is a complicated formula for calculating the correct grout joint size for your tile. But to keep things simple, your grout joint should be in the range of 1/8-1/4 inch for many of the 12×24 tile installations. [2,3]
Your choice of thinset is important for 12×24 tiles. You want to make sure that you choose a modified mortar meeting ANSI A118.4. Additionally, look for words like medium bed, LFT, LHT, or simply “large tile” on the bag. Make sure to mix your mortar properly and follow my tips for small batch mixing, as well. Finally, selecting the correct trowel ...
Bigger tiles require flatter floors. Tile industry standards say that your floor should not deviate more than 1/8 inch in 10ft for large format tile. Since most floors aren’t that flat it means that you will have to do some extra work to get it flat enough before you install your tile underlayment. Self-leveling a floor for tile is one way to help...
I recommend using tile leveling systemsfor installing 12×24 tiles and larger. Leveling clips don’t get you out of flattening your floor. They aren’t a short cut for some other step. But they can help with the installation and they may even help bend the tiles slightly. Look into using them. I’ve been surprised by how much I’ve come to rely on tile ...
