..only partial because I don't know how it will hold up to greasy steam, but...
..when I started making guitars, I followed instructions to use double sided tape as that's sort of the norm. I bought some of the strong stuff like suggested here and it's too much for templates. The amount of stick that it has is over the top, and the adhesive doesn't just let go right away - it stretches as you're pulling the template away.
I've gone to putting screw holes in templates where they won't show up on a guitar as the tape was just way too much.
Other options would be some of the thinner construction adhesive, but it would have to be spread thin enough that it won't leave lumps under the tiles.
