Hi, can anyone pls suggest a suitable bonding agent to stick large marble travertine tiles (20mm thick) vertically to a pool wall lined with vinyl liner? The travertine will be supported from beneath by a concrete step taking much of the weight, so the glue / bonding agent will not need to support the (shear) weight of the marble...just needs to keep it attached to the wall. Pool is filled with chlorinated water and approx. 1/2 of the travertine will be below the water line. Grateful if anyone has any thoughts? I've added a photo showing the travertine patio and the vertical step with white & grey pool liner over which I want to stick the travertine. Thanks alot.

I would paint flexacryl on the liner edge first, then when its set, use tile grout and bed the travertine down

Ok thanks, what does the flexacryl do / what's it for?

The pool guys said I could try Ketamine with Isolastic or Kerabond but i've no experience of either solutions tbh.

flexacryl is used for repairs to roofs and will bond to virtually anything, have not used the other products so cant comment on them
