·I've decided to try a little concrete mix in the background, just to experiment. I picked up a pail of Quickcrete Quick setting concrete mix. So far so good. I mixed equal parts of coco fiber, peat moss, and concrete mix and blended well. Then I added two parts dry mix to one part Quickcrete concrete bonding adhesive and mixed to a lumpy consistency. This was applied to a large scrap piece of Great stuff that had cured completely. The concrete starts to set up in 10-15 minutes, but takes 48 hours to fully cure. Once the mix started to get firm, I pressed in some more coco fiber/peat moss to add a finished layer.
So far the mixture has bonded to the foam very well, as far as I can tell. I will leave it set for 48 hours to dry completely and see how well it sticks. I'm not concerned about anything leaching because the peat/coco fiber layer seems to create a "crust" that hopefully will be water resistant. I'll know in a couple days.
