Thank you all for the replies, and it looks like I should just go with foam-safe caulk.
Probably is too late for him not to use foam. A lot of people like foam, I didn't even know it was a controversy.
The question is a "reinvent the wheel question."
Elmers says: "The durable, clear-drying wet tack glue that offers a long-lasting bond, and post-drying flexibility. Safe and non-toxic, this glue won't run and is ideal for multi-purpose craft projects involving porous and semi-porous materials.
It's virture of post drying flexibility isn't needed and neither the track nor the foam are porous.
The questions are: is it foam safe? Some glues eat into the foam. Does it make a good bond between non porous surfaces? Can track be easily removed, as with caulk, if there is a need to change or tear down the layout?
If you have a supply of tacky glue, it's probably worth while to try it on a piece of scrap foam. Otherwise it's a more expensive product with uncertain results.

IMO. tacky glue is well, tacky. May be hard to spread. And willcost more.
Plain ole latex chaulk works well
mbinsewi I don't see why not. I used caulk, but that was my preference, just regular latex white. If your unsure, do a little test section. Not sure about the spray variety that Elmer's has. You just want an adhesive that won't attack the foam, and anything solvent base will melt it. Mike.

I didn't think of doing a test section, but I may just end up going with foam safe caulk
2 layouts with foam, no issues. No excess noise, either. I just used cheap caulk, but other stuff shoulkd work. I suspect caulk for the cork to foam and also for the track tot he cork plays a part in not making it noisy, but it didn;t get any louder when I ballasted, either.

Bayfield Transfer Railway Is it too late to tell you not to use foam? Tried it, hated it, will never touch it again.

i know that elmers spray adhesive wont attack foam itself , but DAP foam safe caulking [in a large tube] is a fair bit cheaper .. i used clear and white DAP cauking on foam to foam, and foam to plywood ..with a squeeze gun

This may seem like a stupid question, but I am about to glue down my cork roadbed to my foam base. I have seen people say that foam safe caulk is the best way to go. My question is, can I use tacky glue, like Elmer's Craftbond Tacky Glue instead of caulk and still get a comparable result?
