Anyone who knows tile, they want a flat surface, level may or may not be required, but is often nice. Any tile is MUCH harder to get to lay flat when the substrate is not flat. He performed a screed layer of thinset that would be VERY difficult for a DIY'er to perform. He chose to not follow the instructions of the manufacturer on the tile size installation. I did say, and the manufacturers of both Ditra and StrataMat say to level the floor BEFORE installation of the membrane.John chose not to do that. I never said the floor shouldn't be level. Using recommendation from one company to apply to a similar product is a personal decision, and does not mean there are characteristics of the two materials that allow the same techniques to work.

Pick a product designed for the intended purpose, and install it per the manufacturer's instructions. Without the specific instructions from the manufacturer you posted.someone just skimming the thread or the title could easily be lead to an improper conclusion and not generate a reliable project.
Both of the mats in question are marketed for DIY'er and pro.my vote, leave the exception to the pro. The manufacturer's goal is a reliable installation for the target user. And, they may then make assumptions, and create a bad situation. Plus, many DIY'ers do not read, and when they do, they do not always understand the instructions or the ramifications. Yes, there are ways to do this, but most people won't take the time to accomplish it properly. IHMO, to achieve a good install with tile smaller than 2x2" over a mat like this requires more skill than a typical DIY'er and some pros to be able to get first, a consistent, level screed the proper depth over the top of the mat, and if it isn't, get the small format tile set so that they are acceptably flat. I've thought about this, and I think this thread does not belong in a DIY'er forum. So, with the multiple diversions from the manufacturer's instructions, while this floor might last, all warranty would be in question.best to do it the way the manufacturer calls for. Per the installation instructions (page 21), all leveling must be performed BEFORE installation of the mat. Thinset mortar makes a great bond to tile when done right. Thinset mortar is not designed for floor leveling. On these mats, any required leveling must be done BEFORE the mat is installed. Throw in a good sized lady in spike high heels, and your results may differ.
#Laticrete strata mat crack
on top of the mat does not negate the fact that a small tile will end up over a void, and while a point load in a bathroom is unlikely to crack a tile, it is against all that the manufacturer calls for. Tile hates voids (a bigger tile will be supported by enough columns of thinset to keep it from potentially tipping with a point load), and IMHO, the combination of multiple layers of thinset, mesh, etc. Specifically designed for use with both modified and unmodified mortars, STRATA_MAT allows for the proper adhesive mortar to be used with porcelain or large format tiles and stone.FWIW, the reason there's a tile size minimum on this type of membrane is that the raised portion of the grid does not have mortar under it.IOW, it is a VOID. The unique patent pending design of STRATA_MAT provides for an enhanced mechanical bond of the adhesive mortar and provides for faster drying of the mortar, allowing for shorter time to grout.
Designed to replace traditional underlayment materials.
STRATA_MAT is a next generation high performance uncoupling mat for use under ceramic tile and stone installations, for both residential and commercial applications.
