I am about to use Laticrete's SpectraLock epoxy grout on a kitchen
blacksplash. 4.25" square glazed tile, 1/16th grout line. I have the
"narrow grout line" additive.

I've done several tile jobs in the past, including floors, counters,
tub, shower, walls, but I've always used conventional grout.

Does anyone have experience with this grout? Advice? Tips and/or
tricks?
