Making some large Moulds ( 2.5m x 2.5m ) at the moment and this unusually hot weather is really slowing me down. Even at .75% I can only mix 5-600grms of resin at a time, giving me about 10 minutes before the stuff starts to gel in the pot. I have now started mixing 4 or 5 batches in tray like containers and putting them in the fridge before use. This is helping but has anyone else developed any cunning solutions?
