Silicone coated with -sand-?

I think I'll do a test this weekend, and see how it works. I figure I can test it on just about any surface, so long as the silicone is in place. I'll update with the results here ASAP.

Maybe you can see my waterbedding in the photo album , not sure if I did put it in.
Here some use silicon as well, even for an entire back wall.
I use epoxy raisin for that purpose .
It's far more durable and easier to work with, especially for you're water feature and waterfall.
