6x12 two level layout; now what to cover or paint over all that surface?

Thanks. Good tips. I've read and done a lot on the mechanical aspects of our great hobby, (wiring, repair, benchwork) but as I enter into the more "artistic" realm, I'll need more study.

If spread very thinly, two small bags might (might) do it, but I doubt it. I would bite it, buy two of the mid-size or large bags ($18?), and one bag of "bushes" to make it look like a large plain or prairie. Place the bushes individually with tweezers. Dip the one edge in carpenter's glue, and then place randomly around the layout. Don't forget that bushes grow out of the edges of the ballast. Also, that bushes regenerate, so they will appear in clumps, not one here, one over there, etc.

How much foam would be needed to cover the area?

I would disagree, and suggest a light tan with one or two small bags with different colours of Woodland Scenics ground foam sprinkled lightly over it. The effect will be pleasing and not look unfinished, even though you have used so little material at so litle cost.

Dark Brown flat latex paint will not attack your foam. Copy nature for bare earth...you can always "plant" grass, shrubs, trees, etc., later...heck, you might even want to "pour cement" (flat grey latex) in certain areas...

Definitely cover it in a base of a earth tone paint, then anything you put down will blend with it.. I used some Scenic express ground cover in the form of a fine green for kawns. They make some heavier material that may suit more for the Yard Look you are going for,

At this stage there are two levels of 0 gauge track on pink styrofoam. The railbed is simulated with a modest amount of ground stone.
I would like to see your replies about relatively easy (time-effective) methods to cover the remaining 72 sq. ft. There will never be buildings, water, or mountains. I thought about an industrial look, black paint, or a uniform layer of sand. I'm certain the forum will offer something better.
Thanks.
