Kraken Bond Fastcoat Fire Rated Spray Foam Insulation Kit - 12 Pack

In this review of the Kraken Bond Fastcoat Fire Rated Spray Foam Insulation Kit, the bottom line is simple: it is best for homeowners and contractors who need a ready-to-use, fire-rated closed-cell foam solution for gap sealing and targeted insulation work. The kit ships as a complete package for immediate application and the single biggest reason to buy is the Class-A fire rating combined with a high R-value per inch, which gives added confidence for attic, wall and garage door perimeter work. This review focuses on real-world use, coverage expectations and ease of application.

Key Features

• Class-A fire rated: The spray foam meets ASTM E84 classification for improved fire resistance, making it suitable where enhanced safety is a priority.
• High thermal performance: Closed-cell polyurethane delivers approximately R-5.66 per inch to reduce heat transfer in attics, walls and crawl spaces.
• Complete kit for start-to-finish work: Includes twelve cans, an ergonomic application gun, foam cleaner, goggles, worksuit and gloves so a single order can begin a project right away.
• Versatile dual-nozzle design: The dual-nozzle system helps reach both vertical and overhead spots for more thorough coverage in hard-to-reach areas.
• Temperature guidance for reliability: The manufacturer recommends warming cans to about 68F for peak performance and states application works between 41F and 86F for flexibility.
• Air and moisture sealing: The dense, monolithic closed-cell foam creates an airtight and watertight barrier that helps block drafts and pests.

Who It's For

The kit is aimed at DIYers and professionals who need a portable, full-package insulation solution for spot insulation, rim joist sealing, garage door perimeters and attic gaps. Its Class-A rating and included PPE make it a sensible choice where fire performance and immediate use are important.

It is less suited for contractors planning to insulate whole rooms or full wall cavities by bulk volume - larger, bulk spray systems remain more efficient for large surface areas. Also, those needing a solvent cleaner or replacement gun parts should confirm compatibility as the kit's cleaner and gun are intended for typical small- to medium-scale jobs.

Pros & Cons

Pros

• Ready-to-use kit includes cans, gun and PPE for a one-purchase start to smaller projects.
• Class-A fire rating and good R-value make it a safe, thermally efficient option for targeted sealing.
• Dual-nozzle gun and ability to adhere to most building materials provide flexible application.
• Works across a wide temperature range when cans are properly acclimated.

Cons

• Coverage reports vary; some customers find actual spread differs from expectations, so budget extra cans for larger or uneven voids.
• Not intended to replace commercial bulk-spray equipment for whole-wall or large-volume insulation jobs.

Frequently Asked Questions

How much area will the kit cover?
The kit advertises roughly 240 sq ft total from twelve cans, but customer reports vary so allow extra material for uneven gaps and absorbent surfaces.

Is the foam suitable for exterior gaps around a garage door?
Yes; the closed-cell foam creates a watertight, airtight seal and adheres to most building materials, making it appropriate for garage door perimeters when applied per instructions.

What temperature is best for application?
For best results warm cans to about 68F; the product is usable between 41F and 86F but performance and sprayability are optimized near 68F.
