Hi all. I've cleaned and reset our coping stones around the pool. I'm curious how best to go about grouting the 1" gap to the pool and the 1/2" gap between the coping stones. Attached photo. I have sanded grout for both the pool edge and another color for between the stones. Which one would you grout first, and how is it best done to avoid making a mess in the pool from the coping overhang? Thanks in advance!
