Kraken Bond FastCoat 24-Pack Review
FastCoat holds the provisional top spot for a balanced technical case, an established owner-feedback base, direct-store support and clear surface-spray positioning. The 24-can kit is the variant to compare, and its Amazon product images show two ThermaFoam Wide Spray cans included as a complementary detail foam. It has not yet earned a final Best Research Pick, and the exact fire report and usable yield remain under review.

The 24-pack’s product images show 2 ThermaFoam Wide Spray cans included - complementary bundle value, not extra coverage.
Pack sizes
The 12-pack is the most-chosen size for most single-room and touch-up jobs; the larger packs cost less per board foot for whole-garage or shed work.
Amazon carries the largest verified-buyer history and the easiest returns - useful here, because the most common complaint is cans arriving solid or unusable. The Kraken store adds direct support but a smaller review trail.

Evidence status
How we rateNo single score yet - each product is still under review. This tracks where the evidence stands across our five rating groups.
- Technical & fire docs Partial
- Independent application Partial
- Owner feedback Strong
- Coverage consistency Partial
- Value & accountability Under review
The 24-pack’s claimed 480 board feet is about a small garage or shed at roughly 1 inch. Owner feedback runs below the per-can claim, so treat 480 as a ceiling and budget extra cans.
What owners actually say
Positive but polarized: strong results on real jobs, offset by a recurring group who received dud cans.
Stands out: Several owners cite replacing professional-install quotes many times the kit’s cost - one mentions an $8,000 quote avoided.
Owners praise
- Real cost savings versus hiring a pro installer
- Included PPE and gun rated usable out of the box
- Works well on basements, crawl spaces and cabin roofs when the cans are good
Owners complain
- Recurring reports of cans arriving solid or unusable
- The most frequent customer-service complaints in this group
- Application is messy with a learning curve
Owner tip: Owners say misting the surface with water first and keeping cans warm improves spray and yield.

Frequently asked
How much does the Kraken FastCoat 24-pack really cover?
The 24-pack claims 480 board feet at about 1 inch, but owner reviews consistently land below the per-can figure. Budget extra cans and treat 480 as a theoretical ceiling.
What is the difference in the 24-pack versus the 12-pack?
The 12-pack is the most-chosen size for smaller jobs. The 24-pack is the one we compare because its product images show two ThermaFoam Wide Spray detail cans included as complementary bundle value - not extra FastCoat yield.
Is the fire rating verified?
Kraken states a Class A rating to ASTM E84. We treat the exact fire report and formulation as still under review rather than confirmed.
