Thinset cure time

I am installing some 12x12 Scabos stone (kinda like Travertine) into a basket-weave wood floor (the openings are 24-3/8" square, so that's four tiles per opening with 1/8" grout joints). The basket weave planking is 3/4" x 5" white oak, so I layed Ditra in each square to try to pick up some height since I want the tile even with the top of the basket weave. Unfortunately, that wasn't enough when I tried setting the tile with a 1/4 x 1/4 square notch trowel, so I had to go to a 1/4 x 3/8 square notch trowel, then back butter every tile with a 1/4 x 3/16 v notch trowel held at a very low angle. That got me bang-on with the surface of the wood. The kicker is that I used Versabond which is a modified thinset because I couldn't find any white unmodified locally. I did mix the thinset on the dry side to minimize the water, but I am still concerned now that I may have a long cure time given the thickness of the thinset bed. I am hoping that the fact that the stone is so pourous will help me out, but I sure could use some advice!


TIA.....

Wait an extra day or two before grouting, Greg. Prolly won't need it, but it'll make you feel better.

VersaBond will cure just fine sealed in double ZipLock baggies, so I'd expect it to cure under your tiles.

Your bigger concern is just the thick build-up of thinset under the tile installation over the Ditra. Not so much the curing, but the loss of the design function of the Ditra membrane. Herr Schluter wants the tile should be stuck directly onto the membrane for best results. The type of installation you have with those small sections makes the Ditra pretty much redundant, of course, and you should have no problems with the installation, I shouldn't think.

What sort of caulk do you plan for the perimeter of each of those tile sections?

My opinion; worth price charged.

Thanks for the info, CX - whew! As for Herr Schluter, I wasn't really needing the isolation properties, but rather the height since haridbacker or some other underlayment would have put me over the top of the wood. BTW, the way we laid it out was concrete slab/tar scratch coat/visqueen/roofing felt/5-8ths plywood/oak plank, so the Ditra was set on the 5-8ths ply.

As for the caulk, that's a good question. Given that the planks are only 5" wide and that they are glued and nailed to the floor, I'm not expecting a lot of movement, but then I didn't expect to have a daughter either, so you never can tell. Got any suggestions?
