I've never worked with resin before, but I'm trying to coat some plywood right now. I mixed what I thought was the correct amount of resin (1 quart) and hardener (3.5 tsp). I managed to coat two panels, but all of the sudden the mixture starting setting up, I guess. It had the consistency of jello. This happened after about 10 minutes. Does this mean there was too much hardener in it? I need any tips for mixing and applying the resin to the plywood. Thanks!
