How to install wall cap through stucco?

Hi,

I'm in the process of replacing my upstairs bathroom ceiling fan.
Like many others I've read about, I disovered my current fan vents into the attic. Someone years ago tried to vent it to the clay ventillation pipe (3" - old Spanish-style house). So it seems the best way to remedy this is to install a 4" wall cap and properly ventillate the fan.

But I can't find a good description of haw to install the cap through a stucco wall. One site said to drill concentric holes through the stucco with a masonry bit and then chisel it away. Is this the best way? Then jigsaw the rest out? Also, what about attaching it to the wall? Can I use some kind of adhesive then caulk?

Any info would be appreciated. Great site by the way!

Stucco

The best way I've found is to drill numerous holes around the circumfrence of where you want to remove & chip it out with a hammer & small chisel. What is behind the stucco?

What Grady said.

You can use polyurethane caulk as an adhesive. Hold the cap in place with duct tape until the caulk sets.
