I place into a pressure pot @40 psi for 24 hours and keep in my closet. I live in Southern California so I don't imagine the pot is subjected to extreme hot or cold temperatures (from the outside)
Will Alumilite Water Clear cure hard enough to not be markable by a fingernail or should I look for a different resin. Do I need to mix larger batches (more than 20g of A and 20g of B). Do I need to mix for longer? The first time I pulled a mold out of the pressure pot at 3.5 hours it was practically still wet despite a demold time of 2-4 hours. Really looking to solve this mystery. Will try to provide more information if requested.
I think I may know why it did that - the Clears takes a lot longer to fully cure and it's not fully cured yet. I've worked a little with them and have had them come out "tacky" after 24 hours and after they hit full cure they're hard as a rock and smooth like they should be. It's just a matter of time to let them hit full cure and they should be fine. A little heat will speed the cure up too but don't add too much or you'll chance burning or discoloring them. Give it a couple days and let us know if you still have any problems with it.
