I use Alene's Tacky Glue for glueing cork to the Dow Blue foam and for the track to the cork. Alene's seems to be just a heavier bodied version of Elmer's. Anyway, never had a single issue with it, and have ballasted near 200 feet of Atlas HO Code 83 track, using alcohol as a wetting agent and diluted Elmer's. None of the track shifted or moved at all. Also, Alene's sticks the cork to the blue foam. On the areas where I have changed the track arrangement, I have to grab the cork with pliers and pull up. Sometimes the cork is stuck well enough that the cork tears in half and I have to get another bite with the pliers.
