I flipped it about every 10 minutes with an ace of spades

mine was really soggy still from being expanded the same day.
all together I would say it took 30 min per large sheet. first 2 sheets were done, my partner in crime got started applying it in the tank. by the time he needed more it was coming out of the oven. we were pretty much in sync with the application and the drying through out the finish of a 90 gallon.
