I want to put a floor threshold between a bathroom (ceramic tile) and hallway (wood laminate). I bought, cut, and stained a wood threshold (transition) to fit the door frame, so I would like to use that one if possible.
The grout between the laminate and tile (put in by previous owner probably within the past couple of years) is cracked along part of its length, missing a 1/4" by about 2" chunk in the middle, and separated from the laminate along the rest of its length. I.e., it's not attaching any part of the laminate to the tile.
Do I need to fix the grout before putting the threshold on top of it? If so, does it need to be a good bond, or is it enough to just fill in the gap without doing it over? (I am planning to use Liquid Nails adhesive or the like to bond and hopefully seal the threshold to the floor surface on both sides of the grout bead.)
