I need to tile the floor in the porch and entry hall (total area about 3 sq m). The problem is that once the tiles are laid, it should stay undisturbed for at least 12 hours (better 24). This is where the issue is. While there is another entry door into the house (via garage), the entry hall is the place where the stairs from the ground floor to the first floor start. There is no option of moving out for a couple of days, so the work will need to be done with the family present. Only using one floor for 2 days is also not an option with the family of 5.
The only thing I can think of is to tile in the evening after the children have gone to bed - and hope that the adhesive will set enough to walk on the tiles in the morning.
The tiles are ceramic and going on 18 mm plywood.
Is there anything I can do to improve my chances of it drying overnight? Maybe some special adhesive?
