Question:

So, when putting tiles inside, you use thinset and cement board under the tiles. What to do when outside?

What do you use under the tiles, and do you still use grout as well?

Answer:

Normally you install tiles over a concrete slab using modified thinset for exterior use. Regards, Dale

Use sand and cement mix with water proof-er in it and use the same to grout.If you want to grout the tiles a different color mix a cement dye in the cement you are using as a grout.
