This stuff is not too stinky so you don't have to use it outside. It bonds very well to anything I have tried it with and sets up quickly, but not too quickly. One thing I used it for was cementing the dryer exhaust vent to the house. Just be sure to mix it up with something disposable -- I use a paper plate and a popsicle stick. It will dry to a gray color, so don't use it on something that needs to be clear.
