Travertine fixing

[ds1980]

Hi all stIll doing the wet room and just about up to tiling. Have 100 mm trav for the floors. We us nicobond gear. Tile shop has given us adhesive but just wondering about distance between tiles. I remember someone saying it should be quite wide. It is unfilled and unhoned travertine. Also what sealer to use and when. I only have a topps tiles nearby will there stuff do and which one should I get. Thanks for help. Ps they are going on top of ufh.

not sure about Topps addy, I've never used it. But if it's a heat mat or loose cable UFH I'd be slc'ing it and use a de-coupling membrane too.

Loose cable. Concrete floor. We have the insulation board to go down first then laying ufh on that. What is a decoupling membrane?!?!? Ta

 

[faithhealer]

4mm joint gap for me, might be able to go down to 3 if using a decoupling mat but open to discussiion

 

[doug boardley]

this yellow membrane ds, it negates any lateral movement due to expansion/contraction. If you look carefully you can see the ufh beneath the slc on the part of the floor that hasn't yet had the de-coupler fitted

Ok thanks for that. Were going to do the slc with te tile adhesive. No insulation boards in wet area. Maybe do that bit with slc to create the slope needed to get to my drain. Using flexible thin set adhesive with about 4mm-5mm gaps was my thoughts. Would there be a problem with this? Ta

ps ufh will be on top of insulation boards

pps concrete floor is existing not a new one so no reason to think any movement???

but your ufh will heat the adhesive and cause movement to some degree. If you use slc, it completely encapsulates the ufh so that you get no "hot spots" or voids where heat pressure can build up. I use tile adhesive (rapid set) to fix the wire down, using a grout float, this then stops the ufh floating to the top.
It's your call tho'.

??? Sorry I'm new to this. If you use both where does the slc go. This is what I was thinking. Concrete floor. Tile adhesive to fix the insulation boards. Obviously boards on top. Ufh wire using glue gun. Tile adhesive. Travertine. Can't see where I would use the slc? In wet area. Tile adhesive and trav. Or possibly slc. Not decided yet? P is anyone watching the cycling? Womens sport is so bad!

Oh and when do I seal the trav. After I've set it? Is topps sealer any robin hood?

Great pic doug...











p.s moved to stone tiling forum.

OK update on floor. So far so good. Didnt need to get a "professional" did it all myself with a start from the FIL. Probably the easiest floor i've ever laid in fact. Ive only done 4! Tiles were soft but i had none snap or break. Took me quite a while so as far as i can see a professional stone layer would do the job quicker but certainly not any better?

Obviously time will tell but ive been jumping around on them to no ill effect! Looking forward to sealing and grouting but did a couple to start with under the toilet and under some boxing im doing and it was fine.

Thanks for all the help but if any of the pro's want a hand call the amateur!

Ha

oh yeh forgot to mention my trav 20x20 was £3.96 a square metre! Bargain!

Will post pics soon!
