I don't even let the glue dry. I give it a minute or two to let the glue get a skin, then I slap the patch on it and press with my thumb and massage it until glue oozes out all the way around. If I don't have enough glue all the way around the edge, I add more from the tube. I then smear the glue around the edge of the patch and cover the orange in glue, wait 5 minutes and inflate with a couple of psi to hold form to re-install.

Yes, it's a messy way to do it, but it works every time for me and it's fast.
