First build - help!

Making a new viv background using the great stuff method, but I'm unsure about letting it cure and stuff.. What's the best way to do it? Should I do the foam and then apply the silicone and Eco-earth straightaway or let it cure a bit first and then do it.. Help please

let the foam cure. As the foam cures, it will expand, then shrink some. Once the foam has cured, use some low grit sandpaper to rough it up so the silicone will stick better, then press the coco fiber into the silicone.

Before applying coco fiber you can carve a bit the great stuff with a cutter (when fully dry) for giving it a more natural shape otherwise great stuff is to "round"
