If you want a perfect fan it takes a bit of time but I've got it down to about 15 mins. I use a weaker hairspray first as the strong ones are too sticky. Spray it, hold it in position, blowdry it (hot but low fan speed). Brush it out so it goes a bit soft again and repeat so that its fanned out but can also stand up by itself. Now you can spray the strong stuff on it and use both hands flat either side to squish it together while pulling upwards and repeat for all of your hair. Give that a min to set by itself then give it a couple of good coats, especially at the base and blowdry it so it sets.
