Having finally gotten the structure operational, I am free to move on to the fun cosmetic aspects of my folding game table project.
Having previously tested this medium on my tree stands, I used sawdust instead of sand to texture the gaming surface. Though the finish is a little more rough, it weighs considerably less, and, more importantly, is porous. This allows glue to permeate the material itself and bond better than sand.

Sawdust is also free if you ask at a hardware store that cuts lumber on site, provided you bring a container.
Taking a cue from Flames of War basing, I roughed up the glossy surface of the pressboard using large grit sandpaper so the adhesive would have a better surface to hold onto, then I painted white glue onto the surface and shook out the can onto the board.
While I had agonized over the potential purchase of one of those large jugs of glue available at most hardware stores, the high price of the large bottle led me to a more incremental approach. I tried one small bottle at a time, since I already had a few on hand. It turned out the be the right decision, taking about 3 1/2 bottle to cover the whole surface (costing the same number in dollars).
With the loose sawdust in place, I pressed it into the glued surface using large cardboard tube as an ad-hoc humongous rolling pin, and swept the loose debris off with a small broom after the glue had dried.
