I made a hole in the side of my house to install a dryer vent. I want
to seal around it with the spray expanding foam insulation. Looking
at the Great Stuff brand, I can either buy stuff that cures rigid or
flexible. Here are links for both (rigid first):

http://building.dow.com/na/en/produc...windowdoor.htm

Which one would be better? And it says on the can that it is designed
for one use, rather than using it a bit and saving it for a future
use, because the dispenser gets filled and cures. Is there any way to
save it for a future use?

thanks in advance,
John

Unless you need the softer stuff, like around windows to prevent
jamming, I prefer the rigid foam. It is much easier to trim after
hardening for a neat fit.

The original multi-page instructions that used to come with Great Stuff
(along with a pair of disposable gloves) had this tip:

Remove the tube and nozzle/trigger. Moisten a toothpick and place one in
each opening where the foam was: One in the can itself, one in each end
of the nozzle/trigger and one in each end of the tube. When the foam
hardens, it will stick to the wooden toothpicks and pull out easily. It
works quite well. I prefer flat toothpicks, with the big end stuffed
into the holes.

You can also squirt acetone in each place to clean the foam while it is
still wet.

I used the rigid stuff on my dryer vent too.It came out good Just make
sure you use a little, it will go a long way and expand.
As far as the dispenser, I usually just use drinking straws on the
can, then throw them away. They fit snug on top of the can.

Thanks, everyone, for your advice.

Hey, there is a company now that sells spare nozzle packs that work with
great stuff and other brands, they are in my local hardware store,
www.xtendafoam.com , No brainer, saves me from throwing away half used
cans and trying to clean out the nozzles. Enjoy!
