I picked up a bottle of this stuff quite some time ago, but I haven't ever gotten around to trying it. I noticed that the bottle warned that it expands, and that's kept me from experimenting. Can't think of a lot of applications in modeling where expanding cement would be useful. But I thought I'd ask and see if anyone has experience with it, and what, if anything, they've found it useful for. Does it really expand, and how much? What does it bond well with, and is it better for shear or compressive strength?
Thanks!
