It does not create more "suction". But folks are comfortable using it in an area where there is a lot of misinformation and misconceptions, it is not that it preforms better than well mixed mortar using straight comb and 90% coverage, but it works well enough that the tile never falls from the ceiling.
You're input definitely holds true more than others. I'm never opposed to sharing in a debate. But when you talk, I listen. Some others though....SMH

Craig is the CT tile God.

Just don't hire him if you already installed base...
 
So my job this week. Another contractor installed 450 sf of Ditra heat over OSB subfloor with Unmodified mortar. Ran the cable and everything. The owner read the Schluter manual that was left in the room along with the unmodified mortar bag in the trash and called the Schluter Rep. I was asked to Tear it out and do the re-install by the flooring dealer, the work was well done, just used the wrong product. We tore it out and ground the residue and installed new ditra heat mat, and reinstalled the cable. Oh and guess the tile --- 8x36 rectified porcelain plank with 1/8 grout joint.

Will post picks when finished.

I guess the take away here is remember to use modified mortar on wood sub-floors when using Schluter Ditra products.

The lesson is clean up your job site and leave nothing for them to snoop around.

How easy did the Ditra heat mat come up with the unmodified?
 
He's a idiot or you don't listen.
Shots across the bow :thumbup:

I said back to him "but I thought you need polymer modified to seal a porous substrate and achieve a proper cure?"

He replied "Schluter reps are changing their tune, say unmodified for everything"

Convo maybe 3 weeks ago. Before that I would use modified for Ditra to ply, unmodified on top
