Travertine wet room floor + Warmup system - is this right?

[howsey]

Our wet room is nearly done, just got to tile the floor.

Concrete subfloor left to go off for three months, then thermal board ontop, then tanked using Dunlop system.

Warmup DWS400 wire laid out and taped down, floor tiles all cut to size in a pile waiting to go down.

Question: in the Warmup instructions it specifically says to use an adhesive and grout "with flexible additive".

I've got a bag of Unibond Tile on Floor Rapidset+ powdered adhesive, which says suitable for wet rooms and underfloor heating but I can't find the word "flexible" on it anywhere.

What do you reckon - ok to use or not?

Personally, the only Unibond product that I would entertain is their PVA.
Sounds like you've spent the time and money to do the job well - don't blow it using sh*te adhesive.

Thanks - was going to do it tonight, but thought I'd hang fire and check it out first. I don't even remember buying it.

With Mapei Keraquick must you use their latex to make it flexible?

Read the "recommendations" in this data sheet for advice in when to use the admix.

So: not necessary in my case and use it quick!

Cheers.

Just an update on this: got some suitable Mapei today, found it good to work with. It flows nicely, I got them all down in time but noticed that it does go off quicker than you might like. I had all the tiles laid out in order and to hand to help cut down on "dicking around" time and this certainly helped as you seem to have half an hour to get them down.

..."dicking around" time....
