Grout bandita !
We decided to use a colored sanded grout. We really liked the way it came out (the color is much lighter when its fully dry). Doing the grout work wasnt really all that bad or as messy as we had thought. One advantage was the work area was a flat surface above the ground, so no bending over or grouting on our knees. I would imagine doing a floor and lots of vertical tile would be alot harder.
We have sponged off the surface 2-3 times but there is still a little bit of haze. I’m hoping to get out there right after work today and do the final cleaning so that we have some nice clean shiny tiles on the bar.
