I was at my local DalTile today, and the guy at the contractor counter showed me a product called Dal-Seal TS … he said it’s the house private-branded Noble Seal. Anyone have any experience with either the Dal-Seal or the Noble Seal?
Their stuff is kind of a thick (60 mil?) rubbery orange film with random fibers on both faces. The instructions say it can be laid with either a DalTile liquid product or a modified thinset.

I have no information so ...
Bump.
Perhaps one of the other fine fellows will know more.
nothing here ...
but it wouldn't surprise me if they came up with something similar.
How was the sales pitch?
He do a good job ... make sense?

There really wasn't a sales pitch. I asked about a crack control membrane, he said this is what we stock, this is what it's designed to do, it's house-branded Noble, and it costs $1.39/sf for 5 ft wide. So I bought 90 sf.
They gave me a xerox copy of an abbreviated spec sheet, with very basic instructions. They said the full roll (500 sf) comes with instructions packed inside. At the bottom of the page it says Caution - read complete installation instructions prior to installing. There is a section on the abbreviated sheet that describes it as 30 mil CPE with non-woven polyested laminated to both sides.

Whatever you do, make sure you follow the membrane manufacturer's recommendations about using modified versus unmodified thinset under and over the membrane. On some membranes such as Ditra you need to use unmodified thinset to set procelain tiles over the Ditra. The reason is that modified thinset needs air to set, and it cannot get much air when sandwiched between the membrane underneath and the porcelain above. Unmodified thinset is like cement -- it can set without air.
But follow the recommendations.

I had read here before about the plain vs modified, but didn't know it was the air cure that made the diffeence. The spec sheet fopr the Dal-Seal says to use latex modified thinset between the membrane and the subfloor.
