Tile thinset and grout for scenery?

[OhioRailroader]

I can't remember where I saw it, but I'm pretty sure I did, but did anyone see an article or post somewhere that the author used tile thinset and/or grout for their scenery? I'm thinking it was in Model Railroader a few months ago and it was used for a southwestern layout.

The reason I ask is I may have a little bit left over from my tile work. I have grey thinset left from my bathrooms I did, a very light brown called "smoke" for grout and I might have some white thinset left over from the marble I'm laying this week.

I wonder what I could use it on. They all have a little bit of sand in them, so I'm thinking roads, but I need to make sure it all sticks to my modules really well. Maybe I should put a layer of plaster cloth where I have bare foam board to help with adhesion. The last thing I'd want is for it to crack or chip and be completely out of it, then have to buy a 25lb. bag just for a dime sized patch lol.

If anyone has ideas, let me know!

It is heavy and its hard. Putting trees in it is difficult. Carving and other small adjustments are frustrating. You don't save much money, but you gain a lot of frustration down the line.

Drywall seam cement is much better, even better than plaster in my experience. I still like foam, or plaster cloth with a covering of ground goop. (I use very little plaster cloth since I discovered foam).

Floor tile Thinset and Grout are very brittle and crack as they dry if applied too thick.  The only way I have ever used grout is mixed with other types of plaster (casting plaster and dry wall joint compound), dirt, paint, gerbil bedding, and other ingredients in a mixture akin to ground goop.

 Thanks!

And I had some mud left over today, so I thought I'd test it out in a few areas. So far, so good. It might not stick well to the foam, but a section I put down for a road is holding well.

I guess when I was asking about this whole thing, I should have said I was using it for things like roads, places where rock slides may have occured, gravel parking lots, etc.
