DITRA Doesn't stick to Substrate

Hi Folks,

First of all, let me thank you for all the great advice I got from this forum. Thanks to you, I tiled my kitchen floor without much difficulties.

I have a problem with my living room, though. I tried to lay DITRA using modified thin-set (Versabond) on Plywood substrate but IT DIDN'T STICK!! What could I be doing wrong? The consistancy of the thin-set is pasty. Should I have made the thin-set more liquidy? I remember reading that it's better to have a runny mixture of thinset so that it can seep up through the membrane of ditra and bond.

One of my friend (over the phone) told me that the substrate might 'pine' or some other type of wood, rather than plywood. Would that make a difference?

My understanding is DITRA requires Modified thin-set for wood floors.

I'd appreciate any input.
