I have some Spectralock left over from my bathroom project, next project is a simple outdoor kitchen with a fridge on the bottom and a gas stove on top. No BBQ, I am a charcoal gal and will likely be buried with my Weber Performer

So, and keep in mind this is Arizona, would I run into any problems with using this in a hot environment? It does reach the frost point here every once in a while too, but the refrigerator would still be pumping out heat from underneath. I just don't want cracking tiles should the environment be too harsh. This would be under a covered patio so no direct water intrusion unless there's mighty winds with the monsoon storms.
Thanks in advance!
