any thoughts gratefully recieved!


Silicon is a bad choice, because it is a hard, brittle element.

Silicone is a great choice, and won't come away from the tiles once
cured. Grab adhesives are also fine for this, but some of them don't
squish enough, so the steel will sit 1-2mm out from the tiles. Silicone
squishes better, you can easily get the gap down to 0.25mm or so.
