My method of madness is to find a CLEAR (preferably matte) Hard coat to top coat( aka seal ) my mixture of madness that is just great stuff expanding foam ( pond and stone version) with play sand embedded and adhered to it.
Please bump or comment if curious.
To be clear, as i made structures with the great stuff foam I sprinkled sand all over it and pressed it in before the foam cured. It is safe, it has the look I want, the textrue it needs, and now all I need is something clear to paint or spray DIRECTLY ONTO the expanding foam to give it a more rock like strength.
I have tested one option that seemed promising
This is my test piece of spray foam with sand embedded into it.
Then I added the wood glue in the background diluted with water to coat it. It ended up hardening the surface a good amount but still gave into a firm press between my fingers( have to mention it did not crack or flake just bent and lazily regained its original form) was a bit glossier than I'd have liked it as you can maybe see here.
But it still falls so slightly short of my expectations. I'm Just wondering if their isn't a better hardening coat option?
