Nov 6, 2020 · 50% offset for 12”x24” tile. ANSI A108.02 section 4.3.8.2 is where the answer is. I will paraphrase what it says – When tiles with sides longer than 15” are being set with their long sides next to each other they shall be set in a pattern with an offset of 33% or less. If an offset more than 33% is desired (such as a 50% offset), the ...
Aug 6, 2023 · 25%|75% tile pattern. With a quarters layout, you would mark 1.5 inches (25%) on the tile and put that on the center line. Then, the rows immediately above and below would still overlap by 3 inches. In fact, those rows will hit the center line at the 4.5-inch mark, or 75% of a tile. So, instead of centering on the whole/half marks of the tile ...

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....

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 ...
