Hi Gay,
I know we’ve also been in touch with this by email, but I wanted to answer you here too.
I can understand your concern about the length of curing time. It is normal for this resin to take 24 to 48 hours to start to harden. The thinner the pour, the longer curing will take. More details about this resin can be found as a part of the mixing instructions here: https://resinobsession.com/wp-content/uploads/2020/05/Resin-Obsession-deep-pour-casting-resin-mixing-instructions.pdf.
To make sure this resin cures, you need to keep the curing area warm the entire time, which is 48 to 72 hours.
