Ballast adhesive - Yes or No?

[ezdays]

I use white glue/water indoors also. This question applies to outdoor layouts.

I don't do outdoors, or large scale, so I never gave this any thought as to what anyone does. But it would seem to me to be a problem, although not as much as when using finer ballast. I can see animals, a stiff wind or rain moving things around. Is there any chance that using diluted yellow glue would work? It's water soluble, but waterproof when dried and does dry clear. Unlike with white glue though, you're not going to be undoing things easily.
