Great Stuff, How much is in a can

[madmun]

Can someone tell me how many sq ft can
you get from a 16oz can of big gap filler
after it cures.

Thanks Rich

It's cubic inches, not square feet, and one can will give you just
about enough to seal around a door with a one-inch gap. I would say
that is about 1200 cubic inches, or 2/3 of a cubic foot.

Note that there are different versions. Some expand more than others,
on purpose. The minimally-expanding type is for applications where
things might move, like a window or door frame.

A few sq ft less than one usually needs for any specific job. Be sure to
have an extra can on hand.

Using basic math volume formulas and the detail that a 16 ounce can of
Great Stuff will make a 1/2" diameter bead, by 232' long, the volume of
foam in that bead is ~0.31 cubic feet or an equivalent block of ~12" x12"
x 4".

I think that math is wrong.
5 inch diameter x 3.14 x 232 feet x 12 inches per foot = 4,371 cubic inches
4,371 cubic inches / 1,728 cubic inches per cubic foot = about 2.5 cubic feet.

But you usually get a lot less where you want it, and a bunch all over and in
the can.

Also it uses moisture from the air to cure, so big blobs don't expand as much.

There is 231 cubic inches in 1 gallon. I would guess that a 16 oz can could
produce one gallon of expanded foam. Be careful with math convertions
regarding surfaces, volumes, cubic inches in cubic feet, get them mixed up and
you could end up with over 1700 cubic inches in one cubic foot. I'm no
mathematician but I did once order 27 cubic yards of concrete by the
teaspoon.lol

Just for fun I just emptied a full 16 oz can of great stuff and found it would
make approx. 2 gallons which is approximately 3456 cubic mass inches or 462
cubic liquid inches. Was this helpful?

[trader_4]

I'm sure the OP has been waiting since 2008 for someone to empty a can and
get back to him. Good job! Now, how are you going to get it back in
the can?

That's it? 2 gallons?

After searching for the answer to how much a can of expansion foam creates, I
found your post. Thank you, I was just telling my sweetheart that we should
empty a can into an empty box. You saved me that task...:-)

[marklh...@gmail.com]

Mathguy, Pi x d is circumference. volume of a cylinder is Pi x radius squared x length. You should change your name to big dummy. I hope you don't have a student loan for that education! :)

[EngineeringNOLA]

no he was right. (( (0.5/12)^2)/4)*3.1416*232 = 0.316 cuft

For any given job you need slightly more than one can.

That's one of those rules that ought to have a name.

Then you throw away the rest because there's no good way to clean out the straw and as far as I know you can't buy another.

[AccidentalAquarist]

Actually My company does have a name for that. The POO rule. Purchase Over Optimal. Just like everything else order 15-20% more than needed, and hope like hell you can use the excess on the next job or it becomes fodder for the dump

I know this is a old post, but 1200 cubic inches is 8 1/3 cubic feet. 1200/144= 8.3333
The company says it will fill 6 36"x60" windows .375 (3/8ths) x 1"

[BillofOhio.]

Directions say 6 windows 36"x60 0.375" x 1" Now the math.
12x36=432, 432x1x.375 = 162 cu in. 162/144 = 1.125
12x60=720 , 720x1x.375 = 270 cu in. 270/144 = 1.875
1.125+1.875 = 3
Approximately 3 cu. Ft. per can

I see you failed geometry. A cubic foot is 12 x 12 x 12. Use your
calculator to finish this and you will see your error.

Divide by another 12: 1 CUBIC ft --> 12^3 ==> 12x12x12 = 1728, not 144

[DG Hamblin]

You took 1200 and divided by 144 which is inches in a square foot not a cubic foot.
1 foot = 12 inches
Volume L x W x H
In feet 1 x 1 x 1 = 1 cubic foot
In inches 12 x 12 x 12 = 1728 cubic inches (144 x 12)
1 cubic foot = 1728 cubic inches
1200/1728= 0.6944 cubic feet

[jgrimm]

> /3 of a cubic foot.
No your both wrong. He answered 2.5 ft^2. Your answer
is correct. 0.3166ft^2,
so your wrong to say he was right.

Thanx very helpful

Use the first straw on the second can as well, that way you have the second straw for another time.

You can say that again!

[John3]

> cubic mass inches
144 square inches is one square foot, one inch thick. To get a cubic foot, you have to multiply that times 12. There are 1,728 cubic inches in a cubic foot. or,approximately 7.5 gallons.

A cubic foot is 1728 cubic inches! 12x12x12=1728 144= the surface area=ING 144 I have 9 grade education wtf are you people smoking this crap isn't rocket science! I sure hope this last guy is a contractor Jesus I feel like a genius in this group! Thanks guys I needed a good laugh. I've had diarrhea all week but thanks to this whole thread I think I've found a solution. Be right back I'm gonna go great stuff my whole ass crack shut. According to my math shouldn't take more than a third of a CAN!!! See what I did there ass=CAN damn I'm freakin hilarious

[byrdman]

12oz can produces 2 sq feet 1 inch thick. This is from spraying it into a 1 ft square form.

I had a can fall off a shelf in the garage. When I found it, it was a
basketball sized hard lump, with the ruptured can 1/2 sticking out of
the side of the lump.

[Ed P]

That sounds more like a piece of art. Did you try selling it?

[Bob F]

No :-(

[byrdman]

Day later it had expanded 50% so 3 board ft in a 12 oz can 3/12*16=4 board feet in a 16 oz.

[DB3]

@Mathfixer - sorry, your math is wrong! The OP was correct at about 0.3 cubic feet. Area = pi*radius squared, not diameter. pi * diameter = Circumference, not area. Volume = pi*r^2*lenght (or height). For a Math Fixer.... well, you know! Chemistry is not your strength either, BTW. Yes, it is a moisture cure, but, well, there's a lot more to it, and it cures throughout, and generates gas to expand the foam throughout.
