I would still wait until Monday and talk to the hardener vendor. My credibility took a major hit with what it turns out I did not know about mat, but I definitely have made some epoxy batches with too little hardener that set up okay. the reason I am sure of it is that I had some left over hardener. I had a gallon of resin and 2 quarts of 2:1 hardener from Raka and somehow I used up the resin and had some hardener left. I am glad I had it around though. I bought a resin + hardener kit that makes low viscosity for sealing and when I have wanted to use some of that resin for lamination repair or adhesive I use the little bit of Raka I had left. The low viscosity hardener smells like ammonia. Works fine, but you wouldn't want to laminate with it. I hope I have enough of it left to do surface cracks on my deck before I paint.
