Tile adhesive advice please!

[ZB100]

HI Have metallic steel tiles (ceramic) for bathroom, which are going on top of cable underfloor heating and cement board.
Have been advised by tile shop that... The tiles should be laid with a standard Cement based adhesive with a liquid polymer admix such as Ardex X7 with Ardion 90 additive or equivalent.
Given this stuff is really expensive - can anyone advise a suitable alternative to ardexX7 and ardion 90?
Many thanks

I presume you mean a ceramic tile with a metallic finish ? If so most if not all single part flexible adhesives will do, just make sure it states for underfloor heating.

Mapei Keraflex, Weber.set SPF , if you require fast setting then Weber do Weber.set rapid SPF. There are lots more and really it depends on what is available to you in your area.
