Kraken Bond vs BEEST: FastCoat and FullStop Compared

Kraken Bond FastCoat leads our published evidence ranking at #1 with 86.7/100; BEEST FullStop is #5 with 58.5/100. That is a documentation-and-buying-evidence result, not a hands-on field test or a brand-wide verdict. FullStop publishes no data sheet on any channel we could find, while FastCoat publishes a dated, revision-numbered sheet.

Research by Best Spray Foam research desk · Published · Updated

The short answer

Which one, and when neither

  1. FastCoat, on documents and traceable reviews

    Kraken Bond publishes a dated, revision-numbered data sheet, a safety data sheet and a manual, and its fire result sits on the sheet. The FullStop record shows no data sheet on the official page, the safety page or either marketplace listing. On the latest readings FastCoat was $29.96 less for the same 24-can kit, $0.55 an ounce for FastCoat against $0.61 for FullStop, and 275 of 283 of the Kraken Bond store’s reviews are tied to an order, 97%, against 25 of 225. #1 at 86.7 against #5 at 58.5.

  2. FullStop, if the marketplace feedback decides it

    The BEEST listing carries 4.2 from 611 ratings with 9% one star, against 4 from 429 with 13% for FastCoat, so more buyers have rated it and fewer of them rated it badly. Its safety data sheet and its quick start guide are published, and the guide is unusually specific about how to apply the foam.

  3. Neither, if you need a document behind the fire claim

    FullStop is sold as Class A and the maker publishes an ASTM E84 flame spread index of 0 for cured foam, but our desk asked customer support for the report behind it and what came back describes a foam of a different color and carries no brand name, so we could not match it to the product being sold. Class A is a band and not a score, flame spread 0 to 25 and smoke developed 0 to 450, and a class statement is not an approval for your assembly either way.

What would change this

The missing piece, named

  • A FullStop data sheet on any public channel would move this page more than any other document. The record shows none on the official page, the safety page or either marketplace listing, and none was sent when our desk asked.
  • A fire test report that names the product would let the fire row rest on something our desk could match to the kit on sale.
  • A larger share of the BEEST store’s reviews tied to an order would change the review row: 25 of 225 today, against 275 of 283 at the Kraken Bond store.

Asked about this pair

Questions people type, answered from the records

Is BEEST the brand behind this site?

No. Best Spray Foam is an independent research publication and has no relationship with the BEEST brand: not ownership, not sponsorship, not supply, not payment. The domain is beestsprayfoam.com because bestsprayfoam.com was taken, and the BEEST kit is read here under the same rules as every other product.

Which is cheaper, FastCoat or FullStop?

On the latest readings, FastCoat at $359.99 at the Kraken Bond store against FullStop at $389.95 on Amazon, both read on October 29, 2026. FastCoat was $29.96 less for the same 24-can kit, which is $0.55 an ounce for FastCoat against $0.61 for FullStop. The FullStop kit holds 643.2 net ounces against 650.4. Prices here are dated snapshots, so confirm the seller before you pay.

Does BEEST publish a data sheet for FullStop?

Not one our desk could find. The record states that no data sheet appears on the official page, the safety page or either marketplace listing as of September 12, 2026, and none was sent when customer support was asked. The safety data sheet and the quick start guide are published, and the quick start guide is where the maker prints its surface-burning indices.

What do the two brand stores’ reviews show?

Read as a pair rather than an average, on September 12, 2026: krakenbond.net served 283 reviews for FastCoat with 275 tied to an order in that shop, 97%, at a 4.66 average; beestusa.com served 225 for FullStop with 25 tied to an order, 11%, at 4.56. Verified there means the review platform could match the review to a purchase in that same shop. An unverified review is not a false one, and a buyer who ordered on Amazon and wrote on the brand site is genuine and unmatched.

Does BEEST make a pest block foam like Kraken Bond PestSafe?

Yes, since September 2026. BEEST FullStop Pest Block is sold on the BEEST store as a kit of 12 oz foam cans with steel wool to pack into the gap first, and it claims no pesticide; it publishes no data sheet, and when we read it on October 18, 2026 it had no marketplace listing and no store reviews. Kraken Bond PestSafe is a 12 oz straw can whose brand store says it is formulated with an EPA-registered pesticide, while its dated data sheet carries a bullet reading "Long-Lasting Pesticide Free"; neither names an ingredient. Our pest block page reads both under the same four marks.

What else do Kraken Bond and BEEST sell in spray foam?

Kraken Bond also sells a gap and crack filler, a window and door foam, a fire block foam, a black landscape foam and a wide spray can, each with its own record on this site, plus Xtreme Pro window and door and fire block gun cans and a fence post foam, sold out when we read it, that this site does not track yet. BEEST sells FullStop insulation foam, as the kit compared here and as cans sold singly or by six or twelve, and since September 2026 the FullStop Pest Block kit; its store carried nothing else in spray foam when we read it on October 18, 2026. Kraken Bond’s adhesive foams, silicones, caulks and glues and BEEST’s Garage Insul8 garage door panels and RV roof products are not tracked here.

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.
