Material is more than likely contaminated with moisture which is really the only thing that can make it harden. Please give us a call and one of our customer service reps will take your name and address and we will send you a new catalyst for your base. Out of curiosity, was the catalyst ever opened prior to noticing it had hardened? If not, was the foil cap still intact? Either way, doesn't matter, we will send you a new catalyst, just trying to figure out what might have happened. Also, how old do you think the kit is?
thx,
Mike
