I have only recently had the same problem in my kitchen. You need a highly polimer modified adhesive. Sourced some ideal stuff from BAL that bonds to this gear. Use either their Rapidset Flexible (cures well quick) or Single Part Flexible (take a few hours) tile adhesive which comes in 25kg bags.
You can buy it at Tile base or Topps tiles or any reputable tile merchant for that matter.
Worked a treat on mine, as I bonded some insulation with this gear to the bitumen adhesive left after I popped up all my plastic (brown - nice!) tiles.

Hope this helps!!
