I had another idea last night Randy. While the fix-all will most likely work just fine and last for years, if you ever move the table, it may chip or crack. Fix-all sets up rigidly and will not flex. That being said, I think that a NON-sanded, latex fortified ceramic tile mortar may just be a better option. Or I should say, that is what I would use unless a professional installer had something better to use. The latex fortified mortars set up hard, adhere to anything, but at the same time, flex - in the event that you decide (or your better half decides) to move the table. A NON-sanded mortar will also be sand able and will spread very smoothly.

Good luck. I’m envious that you have the space for a table. I’d love to have an 8 footer in my home but have nowhere to put one where a miss-cue wouldn’t take out a window.
