Good points Chris (as always). My biggest concern the more I think about it is that portland cement contains quite a bit of lime and I'm concerned that it may leach out over time and that can't be good for any animal. I know you can rinse hypertufa a few times and let it dry and that should get rid of free lime. Thats one of my main reasons for mentioning sealing it, plus the cleaning aspect.



I'll have to experiment with laying it over a plastic shell once it gets warmer. I've seen it laid over tubs and such to make planters and birdbaths (this is where this product excels and was first used) but its always seperated from the plastic. Living in Arctic Northern Illinois there's no way it would cure outside right now and I'm very limited on space indoors unless I pare down the number of animals I have, and we know thats not happening.



For those interested, here is a URL on Hypertufa (one of many on the web, I'm certain and there are differing recipes depending on preference of appearance and finished properties):
