Howdy, I used both liquid nails and waterbased contact adhesive. Both worked well, although I do read about more people using liquid nails. Be sure to pin or weight the cork while the glue sets. Best, mike
I have been using both the WS and cork on my N scale layout. To be honest, I think the cork is a little easier to work with, and is easier to ballast. Most of the WS foam I have laid down requires me to go back with a hobby knife and trim a little ledge overhang from off the top. Otherwise it doesn't look right when ballasted. This same ledge can be found on cork, but is much easier to trim than the foam is.
I use a combination of white glue and track nails to attach the WS roadbed to my foam subroadbed. First the glue, then the roadbed, and then nails to hold the roadbed down. On curves, I keep the nails in the roadbed, but on straight sections I remove them. I may be doing overkill on the curves, but I figure the extra help with the nails can't hurt- and besides, the nails are flat-headed, and pushed down flush with the roadbed. On the track (Atlas code 55), I'm experimenting with drilling small holes in some of the times and putting small track nails in the holes, then after ballasting & gluing I remove the nails on the straights. On my HO layouts I used cork since Day One, and on one layout I even had Homosote (when I was lucky enough to find it) as a subroadbed.
