130m2 travertine, floors with ufh (manifold type and cable) advice on Ditra

[cam_low]

Hello,

I have rather a large job and I know I will need ditra for the floor with manifold UFH, however upstairs in the wetrooms, where it is overboarded, cable, mapei 2 part slc, will I need it here ?

Where can I get Ditra at a decent price to make some on ? cheers

I would recommend it there too boosha. Try one of our forum sponsors PHG, they're based at Shildon so not too far from you really. Is the ground floor a gypsum screed?

I would always advise a decoupler under Trav on a floor with UFH.

Thanks for the reply, I forgot to add that not all of the area is floor ! maybe 60m2...

I dont know whether it is a gypsum screed...I will have to find out...

I've been in touch with PHG and they are going to accomodate my needs with some ci+


cheers

also can you please tell me whether it is essential to join the mats with their special (expensive) tape....cheers

the tape is for waterproofing, so not essential in a dry area, you stick it down with rapid set flexi adhesive

How long you worked for Nicobond then?

I thought the tapping was necesarry, or do you need to make sure a joint doesnt start where two sheets meet running paralel with the joint had a joint crack a while pack on Ditra over ply bang on where the sheets were not taped some gt1 sorted it and the tiles where fine. will not make that mistake again.

For 60m2 i paid £402 for Ditra which i thought was excellent
