Like I said earlier, less is more. The more putty & glue you use, the longer it will take it set.
This is how I would do it:
First: Cut about 1" of epoxy putty and knead it until well mixed
Second: Shape the putty into a circular shape
Third: Add a little bit of Super Glue (Try to find the thicker stuff, it works better. I'm using the EcoTech CG bottle) onto the middle of the putty "disc" set it aside
Fourth: Grab your colony and take out of the water, pat dry the underside (The water prolongs the curing process), and stick the putty disc onto the underside of your coral, leaving it a bit thicker.
Fifth: Add a few drops of Super Glue to the bottom of the putty disc in various spots, keep in mind that the putty will be smushed and will stretch out.
Sixth: Move the coral where you want to place it, twist it back and forth, and hold it there for a minute or so, make sure the coral is in a balanced position as it may be top-heavy
Seventh: Dry your arms and enjoy.
This is what I use:
