Hi Andy,already sent you a pm about what may happened,and here is the answer from west system site:https://www.westsystem.com/instructi...oxy-chemistry/
Controlling Epoxy’s Cure Time

In warm conditions use a slower epoxy hardener, if possible. Mix smaller batches that can be used up quickly, or pour the epoxy mixture into a container with greater surface area (a roller pan, for example), thereby allowing exothermic heat to dissipate and extending open time. The sooner the mixture is transferred or applied (after thorough mixing), the more of the mixture’s useful open time will be available for coating, lay-up or assembly.
