Y'allCanDIY Spray Foam Insulation Kit 6-Pack Review
Y'allCanDIY sells two can sizes, 36.6 oz and 32.8 oz, with the same 20 board feet per can claim on both, a hybrid closed-and-open-cell description, and no data sheet. Its 80 percent closed-cell statement is a number nobody else in the single-can set publishes; its R-8 at 2 in is consistent with it. It stays in the research set until a document appears.

Research summary, not a hands-on test. Product claims on this page are attributed to the sources and dates shown. Before use, read the exact product label, the current safety data sheet and the application instructions, and confirm ventilation, protective equipment, occupant isolation and re-entry or reoccupancy conditions. A surface-burning classification alone does not establish approval to leave foam exposed or to use it in a particular assembly. Included protective items may not meet every requirement for your job; select ventilation and protective equipment from the exact product instructions and the exposure conditions, not from what the box contains.

Research desk note · editorial opinion, not a test result
What to check first
Notice the number that is not on any other single-can listing: "up to 80% closed-cell content." It is the only cell-content figure printed by a can seller in our set, and it is below the 90 percent that the two-component data sheets treat as closed cell. Paired with the listing’s "hybrid" description and a stated R-8 at 2 in, which is R-4 per inch against the 5.66 most cans claim, the numbers are at least consistent with each other. There is no method behind any of them.
Two cans, two units. The Amazon title says 36.6 oz, a weight (1,040 g); the bullet says 33.8 fl oz, a volume (1,000 ml). The Walmart kit uses 32.8 oz (930 g, 750 ml) cans. The brand store sells both sizes side by side. Board feet per can is claimed at 20 for both, so the larger can does not claim more foam.
Y’allCanDIY is one of three brand names sold through one storefront; its letter of authorization names Astemrey LLC, which is the Walmart seller of record for the 18-pack. The shared-seller note explains what that establishes.

How the manufacturer describes it
Compiled from yallcandiy.com and the Amazon and Walmart listings as they read on September 8, 2026. It is the seller’s description, not ours.
- An expanding polyurethane foam described as a hybrid of closed-cell strength and open-cell expansion, with "up to 80% closed-cell content," for attics, walls, garages, basements, roofs and pipes.
- Up to R-8 at the recommended 2 in thickness; apply between 60 and 90 F.
- Two can sizes: 33.8 fl oz (1,000 ml, 36.6 oz by weight) and 32.8 oz (930 g, 750 ml), each with its own straw and red spreader nozzle.
- Kits ship with a Teflon-coated gun, a cleaner, a suit, glasses, a respiratory mask and nitrile gloves; the 12-can kit ships two of each.
- No fire statement, data sheet or safety data sheet on any channel we read.

Technical data sheet · read 2026-09-08
Open:- No data sheet on yallcandiy.com or either marketplace listing. The "up to 80% closed-cell content" and "up to R-8 at 2 in" statements, the second of which works out at R-4.0 an inch, have no method behind them.

Fire evidence · read 2026-09-08
Open:- No fire claim is made and no report is published.
The FastCoat, SprayCoat, ThermCoat and SuperCoat documents state the same yield basis of 20 board feet at 1 inch, the same nozzle A for walls and nozzle B for ceilings, the same 1-inch layer advice with water misting between coats, and the same 24-hour cure with a 40-minute cutting time. The SprayCoat and ThermCoat data sheets also carry the same packaging line, 28.7 oz at a gross 2.05 lb with 12 to a box. We record that pattern and draw no conclusion from it: none of the four states a relationship with the others, and we have not established who manufactures any of them.
Two can sizes, a closed-cell percentage nobody else prints, and an R-value about 30 percent below the figure most kits print

What the differences mean
Weight and volume used as the same number
The Amazon title gives 36.6 oz, the bullet gives 33.8 fl oz for the same can; the store prints both, 36.6 oz (1,040 g) and 33.8 fl oz (1,000 ml). The Walmart can is 32.8 oz (930 g, 750 ml).
Why it matters. Ounces by weight and fluid ounces by volume are different measures of a foam can, and a price per ounce needs one of them consistently.
Sources: yallcandiy.com 24-pack kit page · Amazon listing B0D9CKSJCN · Walmart listing 19889118209
Eighty percent closed cell
The store and listing state up to 80 percent closed-cell content. HandiFoam’s closed-cell sheet prints over 90 percent by ASTM D2856; DAP’s wide-spray sheet prints over 80 percent by ASTM D6226. No method is given here.
Why it matters. Closed-cell content decides vapor behavior and R-value per inch. Eighty percent is consistent with the R-4 per inch the listing implies and inconsistent with calling the can closed cell without qualification.
Sources: yallcandiy.com 24-pack kit page · Amazon listing B0D9CKSJCN
Twenty board feet per can at two can sizes
Both the 32.8 oz and the 36.6 oz cans are sold at 20 board feet per can, 120 for 6 and 360 for 18.
Why it matters. If the claim is right for one size it is conservative or wrong for the other. Yield is a laboratory figure either way; here it is not even tied to the can.
Sources: Amazon listing B0D9CKSJCN · Walmart listing 19889118209
In the box
- Foam cans with straw and red spreader nozzle each
- 1 Teflon-coated gun (2 in the 12-can kit)
- 1 cleaner (2 in the 12-can kit)
- Suit, glasses, respiratory mask, nitrile gloves
One of two kits whose contents list anything for the face: this one says respiratory mask, Adhesive Guru says two face masks, and the other five say protective gear or nothing. What kind of mask is not stated in either case, and a mask is not a respirator with an organic vapor cartridge.

Product overview

Sold in 32.8 oz and 36.6 oz cans, as kits with a gun, cleaner, suit, glasses, mask and gloves.
Manufacturer-stated features
- Up to 80 percent closed-cell content - manufacturer statement
- Up to R-4.0 per inch, stated as R-8 at 2 in - manufacturer claim, no method
- 20 board feet per can at 1 in - theoretical
- Two can sizes, 32.8 oz and 36.6 oz
- Kit includes gun, cleaner, suit, glasses, mask and gloves
Overview synthesized from the brand’s official page and the Amazon listing. Specifications are manufacturer claims, not independently verified.
The 6-pack claims 120 board feet at 1 in, which is one rim joist run or a small shed wall; the same 20 board feet per can is claimed for the smaller 32.8 oz can, so plan on the low side.
What stands out
- Full kit contents, including a respiratory mask
- Own store, Amazon and Walmart
Open questions
- No data sheet; the manual says "NOT fire-rated"
- Weight and volume used as the same number across channels
- Small feedback bases on every channel
- No kit could be bought on October 18, 2026: the 6-can Amazon listing would not open, the one Y’allCanDIY kit page on Amazon that did read "Currently unavailable," and the kits on its own store read as unavailable
Best for
Buyers who want a small pack size to try. The mask in the box is unspecified and is not a reason to choose this kit.
Not for
Anyone who needs a data sheet or a fire rating: there is no data sheet, and the manual says the foam is "NOT fire-rated".
