Allow thinset to dry for 24 to 48 hours. Thinset mortar adheres tiles to floors, countertops, backspashes and walls. It shouldn't be walked on or disturbed during the drying process, as doing so could cause a serious misalignment of the tiles you just laid, a problem that would be difficult to fix.
You should give it 24 hours to dry before applying tile grout, same on both walls and floor tiles, dont leave it longer than a week to grout and dont grout within 12 hours because the tile adhesive has to dry, so i would say tile and then grout the day after, giving atleast 12 hours minimum drying time, but technically do it after 24 hours.
