Kraken Bond Fastcoat Fire Rated Spray Foam Insulation Kit - 20 sq ft

Our review of the Kraken Bond Fastcoat Fire Rated Spray Foam Insulation Kit finds it aimed at homeowners and pros who need a compact, high-performance closed-cell foam solution for small projects. The single biggest reason to buy is its Class-A fire rating combined with a high thermal performance, which makes this kit suitable where fire resistance and insulating value matter. The kit is ready to use out of the box with an applicator gun, cleaner, goggles and protective suit, which helps DIYers get a professional result without assembling separate tools.

Key Features

• Class-A Fire Rated: The foam meets ASTM E84 fire safety standards, adding a layer of fire resistance for safer installation in attics and walls.
• High Thermal Performance: Closed-cell foam delivers an R-value of about 5.66 per inch, providing reliable thermal resistance in small cavities and gaps.
• Complete Application Kit: The package includes cans, an ergonomic application gun, cleaner, goggles, worksuit and gloves so work can begin immediately.
• Versatile Adhesion: The product adheres to most building materials to form an airtight, watertight seal that helps block drafts and pests.
• Temperature Guidance: Performance guidance to condition the can to roughly 68F ensures more consistent expansion and curing in varied climates.

Who It's For

The kit suits DIY homeowners doing targeted insulation and air-sealing tasks around garage doors, small attic sections, wall cavities and rim joists, as well as professionals needing a portable closed-cell option for repair or spot work. Its included safety gear and applicator gun reduce set-up time, which is helpful if you want a single-package solution.

Those needing large-area insulation or continuous commercial application should look to bulk spray foam systems rather than a can kit. Also, people who are uncomfortable handling reactive chemicals or who lack ventilation should enlist a trained installer instead of attempting a DIY spray foam job.

Pros & Cons

Pros

• Class-A fire rating adds safety credentials beyond typical can foams.
• Good thermal and acoustic insulation from a dense closed-cell formula.
• Complete kit with gun, cleaner and personal protection for immediate use.
• Dual-nozzle and ergonomic gun improve control in tight or overhead spots.

Cons

• Some users report variable adhesion and coverage, so results can depend on surface prep and technique.
• Coverage is limited to about 20 sq ft per listed can size, so multiple kits are required for larger jobs.
