Well, there are a couple of ideas I can think of if your goal is not
to seal it, but to also smooth out the surface a bit.  Durham's Water
Putty (available at craft and DIY hardware stores) can be thinned down
a thin paste and spread on the surface of styrfoam.  It becomes very
once dry and seals it enough to use spray paint on it afterwards.  It
also be sanded down, so you can build up several layers and then sand
any bumps or ridges.  I use this product for hiding the joint between
pieces of styrofoam when making hills and such.  Messy, but works great.

Another product is Modge-Podge (available and craft stores).  It's more
a sealant than a filler, but it's thick and works well if you're working
towards a smooth surface.  Again, several layers will probably be needed
to get a very smooth surface.  I haven't used this product for gaming,
I did use it to seal a small, underground cave system designed for my
lizard's tank!
