I still need to do a lot of detail on all of them, and after that I´ll apply more clear. Matte if I can find it, otherwise I´ll be happy with semi-gloss.
As far as brands go, for nearly all the spraypaints I went with Duplicolor. The reason for this choice is that I have a store nearby that sells their products cheap.
The base coat I used is Dupli Color Basic for styrofoam
-relatively cheap and can be applied on pink foam without sealing it with PVA glue first. A single coat covers the surface well enough to allow a 2nd coat with any regular spraypaint without having to worry about the foam being eaten away.

The granite effect spray I used is again from Dupli Color. It´s available in several different shades and colors. I picked a dark grey/black one and a sand colored one.

There are several products from other suppliers, and I think some might even work better then the Dupli Color I used, but again, I went with what´s available (cheap) in my local DIY

The wood enamel or glaze I used is a shop specific labelled affair (Hornbach). I picked pine a shade and mahogani shade glaze to use in my project. Different shades will work, depending on the base color of the effect spray you´re using.
This is what I used:

Bondex also makes the stuff and might be available to you. Even though I now have 3-4 coats of spraypaint on my styrofoam, I still went with an acrylic product because I water it down and it reaches recessed areas that did not get a full coat of protective paint. Still, this stuff can be obtained fairly cheap and a small can covers a lot of surface watered down. You do´t want to use it straight from the can because it´s just too thick to apply it nicely.
The clear I use is Dupli Color Zapon Crystal (semi-gloss)
-Costs a bit more then just any cheap clearcoat, but it can be applied on acrylic- and nitro based- paints, on clean metals and on natural materials like flowers or wood. This versatility took away my doubts to apply it on wood enamel.

I was able to take some pictures using daylight rather then flashlight.
This time I can definitely say the pictures do the board justice. Flash does drown out some of the detail and falsifies some of the colors a bit
I placed another 2 endzone tiles around the board. A 4 way rumble would be possible this way. with 8 tiles and a more random dungeon layout (not placing all tiles in a big square) a 4 way game would be more fun though.

one endzone tile is a bit brighter then the others. This one needs another coat of wood enamel.
