Can you lay tiles over pebblecrete pool coping?

[rochester]

Hi all. 

I’ve got a pool that has pebblecrete around the outside as coping. I was thinking about installing travertine coping tiles on top of the pebblecrete - it looks in good condition, no cracks or sign of damage - I had a tradesperson in recently to do work on pavers elsewhere on the property, he says they should be fine going straight on top of them. 

I’m hoping to get an idea of what adhesive to use to secure the new tiles on top of the pebblecrete. The current coping is a bit all over the place so it’s likely that I’ll have to level it off first - I've attached an image of the coping. 

Thanks!

Had a few friends over to help. One of them had experience in this sort of thing so that was very helpful!
