After I mixed up my resin it gelled sooner than expected,why?
There can be several factors why this happens, the most common will be when we are outdoors, it may have been overcast when we were using a mix, then when we go and mix up another batch (using the same amount of catalyst) the sun has came out (passing clouds) and caused the air temperature to rise around our work and also in our resin mix container making the resin gel faster than the previous mix. Make sure as well that when mixing catalyst into resin that you don’t take too long doing it but mix it well. When fiberglassing outdoors it pays to keep an eye on weather formations so the resin can be adjusted slightly with the next batch if need be or shift your work to an area where the temperature is more stable. You may have accidentally over catalyze the resin making the resin gel faster than it should.
