Great Stuff will stick to everything. Just turn the water off long enough
for everything to dry and then start filling gaps. Even if it doesn't stick
to the liner well, it will form a pseudo liner with the rocks on top of the
liner.

Will great stuff seal a epdm liner to rocks? I have a small stream that I
tested and water flows under all the rocks. I was going to silicone them
to the
liner but great stuff seems better gap filling.
