So this is a bit of a late post for me as I am already using this product, but does anyone know for sure if you have to seal Sculptcrete and in addition, do you know of a safe sealer to use?  I'm rebuilding a waterfall for my ant vivarium (the first was made from Sculpey Airdry and apparently the sealant I used un,,,  didn't work and the whole thing melted.   NOt my favorite result.   
Sculptcrete is supposed to cure like concrete with no need to kiln or anything and it sure FEELS like concrete but was looking for advice

What are the ingredients of the sculptcrete please? Are you looking for it to be completely waterproof?

Sorry I'll get the ingredients later, or you can google it.   So far it's pretty much waterproof but I basically WANT it to absorb water, almost like when we use plaster?   But I'm using it for a waterfall so it doesn't have to be waterproof, completely, it just has to not melt in contact with water like the Sculpey did (I didn't seal it well enough apparenlty)   I still have the Polyurethane sealant to use on this sculptcrete.  So far it's not dissolving after being submerged since two days ago.

If it's concrete then it won't be fully waterproof but won't weaken when wet. No need to seal it. Curing concrete in water for a week makes it stronger as well. Sounds like you've got concrete. Your project sounds really interesting.

I have seen this stuff online. I need to get some so I can try it too. I hope it absorbs some water but you said it doesn't? Let us know how it goes!

It definitely absorbs water.  I think it would work in a traditional setup that would use plaster.   So far the dummy version of the waterfall works really great.   I'll definitely post video and pics when it's done.   The product is just "concrete Clay" as the only incredient I can find listed, and it's just called SculptCrete.    So far I'm loving working with it.   

My only mistake was not making a "base" for my sculptures with foil or some other underlying structure.  It's still really strong, but the structure would have allowed the clay to go farther.  As it stands, I probably used about 50% more clay than I actually needed to use.
