Floating Travertine On Cement Board


Dear all we will be installing Floating Travertine on cement board using Mapei Granirapid. (check photo) We did prime the cement board and the back of the travertine since its covered in resin.
The size of feature wall is around 3.5m x 2m. the travertine is split in 6 pieces.

My concern is that certain pro are saying to use some sort of clips as the adhesive wont hold alone since its floating and very few others say their is no need adhesive will be fine.

What is your suggestion pls

tks

Re: Floating Travertine On Cement Board


Define “floating travertine”.

If you’re bonding it with the mortar how is it floating?

I would use clips for alignment, not retention. Once you pop the clips they’re not holding anything.

Hi Tom floating in terms that the travertine wont keep going till the floor, so the support must all come from the adhesive.

Are you using metal trim pieces around the travertine? If so, screw the bottom one to the wall.

if not;

I would screw a ledger to the wall, set the tile, come back the next day, remove ledger, grout, done.

Re: Floating Travertine On Cement Board


It helps to place masking tape on the top of the ledger, this works as a release barrier. I wouldn't oil the ledger for fear of the oil staining the travertine.

Re: Floating Travertine On Cement Board


from the manufacturer's website:

Do not use for moisture-sensitive stone (green marble; some limestone
and granite, or agglomerates made from these moisture-sensitive stones),
cultured marble or resin-backed tiles. Instead, use suitable epoxy or urethane
adhesives

are you sure the back of the tile is resin coated?

Will each piece of travertine be approx 1m x 1.5m? I had to use a calculator, but that's ~ 3 1/4' x 3 3/4'-that's pretty large tile and I'm betting you put a level across the wall to check for flatness so that the edges of the travertine line up.

A leveling system would be a nice fallback, something like the Riamondi system which has large wedges.

I would probably tackle this job like Tom detailed and being careful to get lots of contact between the tile and backer and not worry about it falling after removing the ledger after at least a few days.

Re: Floating Travertine On Cement Board


from the manufacturer's website, which brand are you referring?

yes we will be using a Raimondi levelling system.

re resin backing looks like epoxy/resin with a net enclosed the glue

Ledger it is then.

If you don’t want to screw into the wall;

Masking tape on wall where the ledger will be,

Hot glue ledger to masking tape in proper location,

Masking tape so you can glue on a couple of kickers to the floor,

Next day, remove kickers and ledger, peel off tape if it didn’t come off with the kickers and ledger.
