Shower basalt tile
I was hoping to get some advice for installing basalt tile in my shower.
I will be installing 3/8" honed Basalt mosaic on the shower floor, and "random strip Milano" Basalt tile (honed) on the shower walls.
My questions are:
what is the best sealant to use for Basalt in a shower?
should the tiles be sealed before being installed and after grouting?
what is the best grout to use for these tiles in the shower?
do the mosaic tiles need to be grouted as well?
I thank you in advance!
