You need to be more specific. What's it for?
I jes bought some expandable foam to fill in the indentations in my
siding (forget the name of the siding) to keep wasps out. Haven't
used it yet, but only a single can (Great Stuff Big Gap FIller).

Amazing how people can ask questions with no info to go on.
I would guess that he's probably talking about something more involved
than a can of spray foam, since he said "kit". Like maybe it's
intended to be the DIY version of the pro stuff that they use to
fill wall cavities, etc. But who knows.. And I'd say it's probably
80% that we'll never find out.
Sorry about that. I hold conversations in my head and forget to
write things down outside my head. :)
This is a 600 board feet kit (about $600 at Amazon). My intention
is first to spray insulation between two roofs in an external,
detached building I'm performing maintenance and converting to an
"efficiency apartment". The second task, later, would be to spray
the foam insulation inside the structure between the non-structural
framing members. Once the inside is complete and cured I plan to
use Great Stuff to fill cracks from the outside. Once the Great
Stuff is cured I plan to apply a plaster/stucco mix to the outside
to seal the exterior. After the plaster/stucco I will paint the
The original application between the roofs will be closed foam and
should be about 1" thick. My idea is to seal the original roof and
insulate. I am considering getting a second kit to apply a second
inch, for a total of two inches, and to make sure everything is
sealed before the second roof (gable) is replaced and sealed.
DIY spray foam kits are costly but invaluable for irregular surfaces. I fo
llowed this guy's recommendation for my retrofit and I'm happy with results
and it was much cheaper than spray foam, but is only good for consistent,
open areas that you can fit cut boards into (i.e. not crazy irregular surfa
ces and spaces).
P.S. for roofs, don't forget to consider leaving an air gap if you have fun
ctional soffit and ridge vents!
IF you have irregular surfaces or spaces, spray foam is a costly necessity.
But if you have consistent, even spaces, consider using board insulation cut to size, and spray foam can around perimeter, like this example:
Saves money over spray foam.
Also, if you're doing a ceiling against the roof, remember to consider leaving an airspace if you have functional soffit and ridge vents.
I understand you have to be very careful to follow the
instructions exactly. If you don't it can wind up
making your home unhealthy. You might want to do a
web search to check and see how other people have
I checked on the web a couple of years ago when I saw
somebody pushing their service at a home show.

Like Arthur Conan Doyle, we used TigerFoam. Two canisters
that looked a bit like propane grill tanks, hoses, mixing
nozzles, everything we needed.
We insulated our crawlspace and a few other areas on the
first occasion, and then we used another batch to insulate
the hot tub we built from a kit. Clearly, since we used
it twice, we liked how it worked the first time.
Follow the instructions meticulously, and don't be afraid to
switch to a new nozzle any time. Buy a few extra nozzles,
just in case. If the mixing doesn't happen correctly, the
foam won't cure properly.
Artie!! How goes it man? Long time no see!
Glad I ran into you because I just finished reading one of your Sherlock
stories and have a guestion I've been wanting to ask you. It's about the
rather singular relationship between Holmes and Watson. I know that
somewhere along the story line Watson get married, but his wife dies after
a few years of happy marriage. Then it's back to that singular
relationship with Holmes again.
It's clear their relationship is "special", but how special? To me it
seems very, very special indeed.
Also, when mixing his 7% solution what does Holmes use for dilution? I'm
assuming water but you never say.
Take care Artie. Keep up the good work.
