I sent you a reply to that buildI used an acrylic sealer from Michaels, it lasted great. I soaked for about a week in a water/vinegar solution. Let it dry for a day. then sealed it an and let that cure for 2 days and then layed my substrate and planted. been running great fora bout 6-7 months now.. I think it's been that long. I've got a thread on it somewhere around here.
EDIT:
Here's my build thread

bah, you can thank JaredJ he pointed it out to me. I'm just reporting back on how effective it's been and passing it along. It's good stuff, relatively cheap and pretty easy to get a hold of.I sent you a reply to that build
thanks for the heads up on the sealant tho I have been using Mod Podge but it can only be used for dry things I used it when I made my bearded dragon's basking platform
