Kraken Bond Fastcoat Spray Foam Insulation - Closed Cell 12 Pack

In this review of the Kraken Bond Fastcoat Spray Foam Insulation, the reviewer finds it best suited to professionals and serious DIYers who need a high-performance closed cell polyurethane foam for thermal and acoustic jobs. The single biggest reason to consider it is the combination of a fast curing, paintable formula with a high R-value per inch that bonds well to a very wide range of construction materials. The 12-pack format and two included nozzles make it practical for larger projects where consistent expansion and coverage up to the advertised board feet are required.

Key Features

• Easy bonding: The foam adheres well to many common building substrates so gaps and joints can be sealed without special primers.
• Quick curing time: Strong chemical bonds reduce wait time and allow handling within hours, with a full cure in about 24 hours.
• High thermal resistance: Closed cell formula delivers an R-value of about 5.66 per inch for effective heat insulation in walls, roofs, and attics.
• Two nozzles included: Nozzle A and Nozzle B provide different spray patterns for vertical and ceiling applications for more controlled placement.
• Wide material compatibility: Suitable for drywall, concrete, wood, metal, PVC, fiberglass and many more surfaces found in buildings and vehicles.
• Pack size for larger jobs: The 12-can set is intended to cover up to the stated board feet for multi-room or professional work sessions.

Who It's For

This product is aimed at professional contractors and experienced DIYers who need a versatile closed cell spray foam for thermal and acoustic insulation across a variety of substrates. It is especially useful when a project benefits from a paintable finish and strong adhesion, such as insulating attics, basements, rim joists, or vehicle enclosures.

Those with only occasional small patch jobs or who need a single replacement can look elsewhere at single-can options or kits that include gun and cleaner; this 12-pack is most cost-effective for larger work or repeated use. Also, users who require very low-temperature storage should follow storage guidance closely to avoid premature aging.

Pros & Cons

Pros

• High R-value per inch offers efficient thermal insulation for fewer passes.
• Paintable, closed cell formula that bonds to many construction materials.
• Includes two nozzle styles for vertical and ceiling applications for better control.
• Sold as a 12-pack, appropriate for larger projects or professional use.

Cons

• Does not include the recommended foam gun or cleaner in the standard 12-can set, which are sold separately.
• Storage sensitivity to heat and humidity means cans must be kept in a cool, dry place to avoid premature aging.

Our Verdict

The Kraken Bond Fastcoat 12-pack is a solid value for contractors and homeowners tackling medium to large insulation and sealing projects who want a paintable, fast-curing closed cell foam with strong adhesion and high R-value. It makes sense for projects where consistent application and coverage matter, though buyers should plan to obtain the recommended foam gun and cleaner separately and store cans properly to preserve performance.

Frequently Asked Questions

Does the set include an applicator gun and cleaner?
The 12-can set does not include the foam gun or cleaner; those items are recommended and available separately for best results.

How long until the foam is fully cured?
Initial handling is possible within hours but allow about 24 hours for a full cure under normal conditions; uneven surfaces or large gaps can slow bonding.

What surfaces can it be applied to?
The foam bonds to a wide range of materials including drywall, wood, concrete, brick, metal, PVC and many composite surfaces for both building and vehicle uses.
