No. I rough up the area around the hole, then run a circular patch shape amount of glue over around and over the hole.
Enough glue so that after 5-10min it hasn't evaporated to nothing in spots. It should be tacky to touch.
Once you've waited the 5-10, wack the patch on and squeeze the shit out of it. Reinstall, inflate, ride.
I never wait more than about a minute before patch on, but I do blow on the glue a bit to dry it out. Never have any problems with it.
Also don't just squeeze the patch but also give it a little bit of a stretch and make sure that the feathered edges are down properly. Make sure that the tube isn't twisted in the tyre as you put it in and if you have time, inflate slowly.
