You’re welcome!! I think there are several styles of walls available, but also I might add, Years ago I bought an 80 lb. bag of hydrocal at Train America. Only have a few lbs. left now, but buying it that way can last for many years & save money over those little milk cartons of it. I think if you do need a lot , you can just dial up hydrocal & search for a place near you. Hope this helps too ! Oh, have fun building that prison!! Thanks, John
Wow, you Buckeyes must not have any humidity. Buy it here and the extra will set up in about a year or so. Even if kept in the house. Can build some thin and light weight stuff with hydrocal.
Same problem here with Hydrocal, use it or lose it. We love that stuff and have probably used 100 pounds over the past two years but I buy it in 25 pound sacks. I’m always shocked when I see the price in those milk cartons, that’s criminal.
