Is there any factors besides the amount of hardener to epoxy that will effect the time it takes to set up? I was using the 15 min mid cure epoxy not the one I use all the time but sometimes and this time it set up very quickly I almost didn't make it. its never set up that quick before on the box it say "apply in temps above 65 deg, can be worked for 10 min with adheasion after 15 min" it gave me barely 5 min if that. I know the ratio was correct could temp be a factor to day is a very hot day and it was the first thing I did today so the air conditioner didn't have time to cool down the room, is there anything I could have over looked that pops into anyones mind?
