Just one more peace of foam board to place on my benchwork and I can begin to lay track…but one problem.
I had to cut a peace of foam 11.5" wide and 30" long (It goes in between two other peaces of foam) It left a seam on both sides. I say the seams are about 1/8" or maybe a little wider. How do I go about filling in these seams so as not to have a gap between the two peaces?
I find it hard to get a perfect fit with out any gaps. Am I doing something wrong or is common when placing two peaces of foam next to each other there is some kind of gap there?
Thank you all in advance for your help with this.
Couple of suggestions. One is to glue down a small piece of styrene over the gap and th other is to use plastercloth. Once you ballast the track, you form a hard base and you should have no problem. If the gap is real large, cut slivers of foam and fill the gap.

Caulk works well, as does Great Stuff. Either way, only really worry about where the tracks run over the seam. In those places, make sure the roadbed is smooth and even/. Everywhere else you can hide with scenery. Heck, I even turned one of my seams into a drainage stream!
Yes, to the last two posts. Lay a bead of it right in the gap, and add another, until it rises above the surrounding surfaces. Then use a spatula to flatten it smooth . Let it harden, and when you do your painting and adding of ground foam, it will disappear.
