I am no expert, but if you are using silicone as your mastic, and if you water-proof your grout (bathroom grout sealer) really well, it should be ok. Not sure anything would withstand a Canadian freezing winter, but I think you are spared that!

Yeah, I can relate to your silicone problems! Can't stand the stuff! Sorry I don't have any really good ideas for how to weatherproof your tg pieces if you can't use resin. Have you come up with a solution since you posted this question? Best of luck!

Hmm just deleted my first answer. You can't use silicone with TG, well maybe you can but it would be too messy and uneven. Resin is the best even outside. What kind are you using? It might amber some but I use the kind that Ellen Blakely uses and her applications are outdoors in California. Flckr mail me and I will tell you exactly the kind of epoxy to use, if you are interested.
