Best thinset and spacers for installing a marble paver pool deck

[poolguy968]

Hi folks, I've just finished pouring a concrete pad around my pool and I'm now planning to install these 16 x 24" Verona marble pavers that are 1.25" thick on top of my concrete using thinset to complete my pool deck.

I'm wondering if anybody has any recommendations with respect to what would be the best kind of thinset to use for installing marble pavers on concrete?

Just based on google search I found two potential candidates:

Custom Building Products Natural Stone and Large Tile 50 lb. White Premium Thinset Mortar MGMM50 - The Home Depot

Custom Building Products Natural Stone and Large Tile Premium Mortar is a premium quality, polymer-modified mortar for any size natural stone or large format ceramic or porcelain tile 15 in. (38 cm) or

I'm not sure if folks here have used either of these thinsets for a natural stone pool deck and have any good or bad experiences to share? I think the Mapei one actually mentions it is suitable for pools but it is also a bit more expensive. Or if you can recommend a better alternative brand that you've used in the past that would be great as well!

The other thing is I'm thinking of grouting the space between the marble pavers and I'm wondering what would be the recommended spacer size? Would you recommend something like 1/8 inch? Or maybe a bit bigger/smaller?

Thanks!
