I just had exterior tile done last fall.

1 - The concrete gets preped wit Mapei (or equal) Planiseal ™ Easy Standard Fresh Concrete Treatment for moisture control.

2 - Mortor / Thinset - Kerabond/Keralastic System is a high-performance, two-part system: Keralastic ™, a second-generation “flexible” acrylic latex additive, is used to enhance the performance of Kerabond ™, which is a premium-grade dry-set mortar. This system has exceptional bond strength, flexural strength, elongation and freeze/thaw durability.

3 - Tile with Porcelain tile, stone ....exterior rated.

4 - Grout with Mapei Ultracolor Plus "with DropEffect™ technology is an ultra premium, fast-setting, polymer-modified, color-consistent, nonshrinking, efflorescence-free grout for joint widths from 1/16" to 1" (1,5 mm to 2,5 cm). DropEffect technology reduces surface absorption to help repel water, dirt and grime from penetrating grout joints."

After a very intense freeze/thaw cycle this winter, everything still looks fresh and new.

Locally we deal with Dal-Tile. I don't know if you have one near you but they are happy to help design a plan of attack for any tile project.

Go to where the pros go.

Good Luck
