Re: Epoxy Kick ?
Most epoxies will not kick "faster" if you add more hardner, unlike polyester glass. It is a different deal, and you actually degrade some of the properties of epoxy by mis-mixing it. From what I have read, there really are only 2 types of hardeners, fast and slow. Medium is a mixture of the 2. I use slow hardner where I am laminating into wood or coring material to get the max. penetration, and I usually pick cool days/nights, and let it sit for 2 days. For must other stuff, especially horizontals, I use med for larger areas, and fast for smaller ones.
Unlike polyester, epoxy has almost an unlimited shelf life, so I doubt it went bad. The thinner it is spread out, the longer it takes to kick, the thicker, the faster it kicks.
I mix mine with a paint string stick in a small cup, with enough action to mix, but not cause bubbles. If the stuff your using blushes, make sure you wipe it clean before recoating or doing anything else with it. I am not familiar with the 3:1 stuff, I use MarineEpoxy from Beateau or MOS brand 2:1.
