My build was finished last summer and we had Oceanside glass tile installed around the outside of our spillover spa. We knew there would be some maintenance issues with this tile in terms of removing calcium build-up so we were expecting that. What we weren't expecting is tiles to be cracking and chipping along a line of what appears to be calcium that is leaching or running down the outside of the spa from the bottom of the coping, which is concrete. The calcium cleans off easy enough but off course continues to come back. This is also a safety issue because of course I'm getting glass fragments that are falling in the pool.
We've also had 2 tiles fall off at the top near the spillover.
Is this an install problem, tile problem, or was a concrete coping on top of glass tile a bad idea?
Here is a picture of the spa right after pool was completed. I'll add another picture of the cracked tile when I get a chance.
