I'm unsure if this resin was left in extreme temps or what but it didn't cure. At all. Ive been using epoxy resin for years and this is the first time I had an entire bottle not cure. It's ruined several projects before I just started testing by mixing various amounts and just setting aside to see if it would cure. The resin I had before and after is curing fine. I'm so disappointed. Worked on this project so long, went to finish last pours to find uncured pickets throughout. Hoping I can fix it.
