I'm not aware of it if they do. Epoxy will degrade under UV, but I'd be surprised if it could get that far into a joint. In some other client I might worry about water getting in and some freeze/thaw cycle breaking the joint open. Most slab also sell materials and equipment for people who are going to fabricate counters themselves. Give a call to the folks who sold you the counters.Hi CarpenterSFO,
Thanks for responding. I understand what you're saying. It's highly possible that's what happened with that guy's granite.
Do they make a special glue for exterior use?
