Tile with adhesive or "glue"?

[AndersNo]

I have a question that I'd like some opinions on...
Traditionally, tiles are set with tile adhesive... But what do you think about the pros/cons of using something like Sikaflex-221?

Adhesive is hard to work with, becomes rigid, and doesn't like movement. - Disadvantages

Sikaflex-221 is elastic, dense, has very good adhesion, and is incredibly easy to work with. - Only advantages.

But otherwise?

harder to tear off glued tiles the day you want to do it - disadvantage.
Otherwise, I don't see any disadvantage, as long as you grout afterwards to make it more water-resistant.

Not really... You can solve that with a knife with a blade long enough to reach behind a tile. Also, you usually can't completely remove the adhesive after tearing down tiles. Or parts of the wall come off with it... Hehe.
We usually don't install tiles intending to tear them down in the foreseeable future, and if that's the case, you can just tear off the entire gypsum board and replace it. You usually end up doing that anyway since tearing down tiles often takes part of the wall with it.

The Sikaflex is not approved for use in wet rooms - disadvantage.
Sikaflex in a tube is likely to cost significantly more than grout - disadvantage.

Correct, but in this case, it's not a wet room.. If I'm not mistaken, there are other adhesives approved for wet areas? Mold-resistant and everything else. But I don't know if they can still be used.. Anyway, in our case right now, it's in a dry area.

Sikaflex in a tube is likely to cost significantly more than adhesive - disadvantage.

Correct again, just 221 costs around 235:- per 300ml tube, but I happened to have a bunch lying around for no other use..

Fix is not hard to work with! Then you probably mixed it wrong - more water! I think fix is nice to work with, it's easy to apply, easy to get the right thickness with a notched trowel, and the tiles adhere well. I wouldn't consider alternatives. I did use tile adhesive when I placed a narrow row of tiles in the kitchen directly on a chipboard, but that was because I was afraid that the water in the fix would damage the chipboard.
