Kraken Bond vs Great Stuff: Gaps & Cracks, Can for Can
Two straw cans for the same job, and two very different piles of paper behind them. Kraken Bond publishes a dated data sheet with a yield, a density and a working range. Great Stuff publishes a gap limit on a product page and no data sheet for this can at all.
The short answer
Which one, and when neither
-
Kraken Bond, when you want the numbers in writing
Its data sheet is dated and revision-numbered and prints what most cans in this category leave out: a volumetric yield of 8 to 12 gal with the test method beside it, a density of 1.37 lb/ft3, and an application range that starts at 28 F, well below the 60 F product temperature DuPont asks for. That paperwork is why it sits #2 on our gap filler page while Great Stuff sits #9.
-
Great Stuff, when the gap width is the number you need
DuPont states the limit plainly, up to 1 in, and that is the one figure Kraken Bond does not publish for this can. DuPont is also the seller of record on the listing we link, which shows 4.5 from 1,922 ratings, and the page gives a tack-free time of 5 to 15 min at 70 F and tells you to paint or cover the foam outdoors.
-
Neither, for a window frame or a fireblocking job
Both are high-expansion gap fillers, and a frame wants a low-expansion foam made for it. Read the Kraken Bond listing title with that in mind: it says "for Window & Door", which the maker’s own sheet contradicts, and Kraken Bond sells a separate low-expansion can for frames. For a fireblocking location neither can carries a fireblocking evaluation, and the fire block page shows which cans do.

Row by row, from the records
Every cell is read from the product record at build time, with the document it came from. A row marks one side only when both were measured the same way, or when only one maker put the figure in writing; everything else is printed without a mark.

What would change this
The missing piece, named
- A gap width on the Kraken Bond sheet would make the two cans comparable on the one number a buyer measures before choosing a can.
- A dated data sheet from DuPont for this consumer can, with a yield and the conditions behind the 1 in claim, would move Great Stuff up our gap filler page on the spot.
Asked about this pair
Questions people type, answered from the records
Is Kraken Bond the same foam as Great Stuff?
No. They are different products from different makers, and even the seller differs: DuPont is the seller of record on the Great Stuff listing we link, while Kraken Bond reaches Amazon through Lotus Global Trade LLC, the storefront that carries the Kraken Bond and Sprayman lines. What each maker documents differs too. Kraken Bond publishes a dated, revision-numbered data sheet with a volumetric yield of 8 to 12 gal and a density of 1.37 lb/ft3; DuPont publishes a 1 in gap limit on its product page and no data sheet for this can.
Which one fills a wider gap, Kraken Bond or Great Stuff?
Great Stuff is the only one of the two that states a limit: up to 1 in, on DuPont’s product page. Kraken Bond’s data sheet calls the foam high expansion and prints a volumetric yield of 8 to 12 gal to ASTM C1536, but no gap width, so there is no maker figure to set against the 1 in. For anything wider than an inch, both makers sell a separate large-gap product.
Which is cheaper per ounce?
On the September 7, 2026 price snapshot, the cheapest bare pack we hold for Kraken Bond works out at $0.35 an ounce, which is 48 cans of 24 oz at $399.89, and the cheapest for Great Stuff at $0.37 an ounce, which is 12 cans of 12 oz at $53.27. Those are different pack sizes and a bigger pack is cheaper per ounce whatever is inside it, so read them as two prices rather than a winner. The two brands share no pack size we could price on the same day.
Can I use either can outdoors?
DuPont says Great Stuff Gaps & Cracks is for interior and exterior use and tells you to paint or cover the foam outdoors. Kraken Bond’s sheet gives an application range of 28 to 86 F and a tack-free time of 7 plus or minus 3 min, and its sheet says "After curing, protect the foam from UV exposure by painting or coating." Cured polyurethane foam of this kind is not made to sit in sunlight, so coating it outdoors is the safer rule for either can.
Does either can insulate?
Kraken Bond prints about R-4.1 per inch on its sheet, stated alongside 0.036 W/m.K to DIN 52612. That is a German test method, and it is not one of the four the FTC names in 16 CFR 460.5 for an R-value claim in the United States, and no aging basis is given. Great Stuff publishes no thermal figure for this can. Neither one is sold as insulation; they are gap fillers, and the insulation kits are a different product.
How this page is built
Nothing here was sprayed by us
This comparison reads what each maker publishes and what the listings show; it is not a hands-on test. Every figure in the tables comes from the product records behind the full record pages, with the document it came from and the date we read it, and it changes on this page the day a record is re-read. A side is marked ahead only when both were measured the same way, or when only one maker put the figure in writing. The rules behind the order on the category pages are in the methodology.
