: hrs.....still soft. Raised temp to 72 deg.for 12 hrs and it is
: still tacky and soft......wtf
: Yes, it is mixed properly.....
: Any ideas?
: Can epoxy take this long to cure and still be good?

Much epoxy used by the trades is heat cured, cures at elevated temperatures in an oven. Won't even set up at room temperature. The reason they use it is it sets up fast at elevated temperatures, some within an hour.
