I am getting ready to glue my foamboard down, it is a standard 4’ x 8’ going on top of plywood. I have 1 small lake bed,12" x 10" to also go around. HD sells the 10oz PL300 Foamboard adhesive, will one tube be enough?
Depending on how deep you stack more foam to create terrain/hills, line tunnels, etc, it may not be. But I had a much larger first layout with quite a few sheets of foam to stack and I only used two tubes of the kind you use in the trigger-type caulking gun.

One word of caution about PL300. Get your foam in the right place the first time. I used PL300 on the benchwork seen below. The instructions tell you to push the foam into place then lift off to vent. I’ll tell ya one thing, once that foam was pushed into place the first time there was no way that foam was coming off to vent. It would not move a micron after I put it in place. Fortunately I put it in the right place the first time. So proceed with caution.
I think the next time I will use latex caulk to stick my foam down. The foam will then be removable and thus reusable.
One tube should be plenty. You don’t need much. Good luck.

Batman, thanks for the info, with that in mind I did a dry test to make sure I could get in the right spot the first time. You are correct, once it was down it was not going anywhere. It is now glued down and has about 200 lbs of weights sitting on top of it. I did not see where it said to remove to vent on the instructions ( maybe they changed)?
I also went to HD before starting to grab a second tube just incase, but one was plenty.
I didn’t use any foam adhesive. I simply used 2 1/2 inch drywall screws through 1 1/4 inch fender washers. The foam is held down securely and the wood underneath is preserved for future use if you want to change anything.
