Key Features & Benefits
  • Exceptional Thermal Performance: Achieve superior energy efficiency with a thermal conductivity of 0.025 W/m.K (DIN 52612) and an impressive R-value of 5.66 per inch. This closed-cell foam minimizes heat transfer, keeping your indoors comfortable year-round.
  • Class A Fire Rated (ASTM E84): Engineered for enhanced safety, FastCoat is tested to ASTM E84 and classified Class A, the top of the three surface burning classes.
  • Seamless, Monolithic Application: Provides a continuous, gap-free insulation layer that eliminates thermal bridges and dew points, ensuring optimal insulation performance. It can be applied easily to uneven and hard-to-reach surfaces where traditional materials are impractical.
  • High Yield & Cost-Effective: One can yields up to 20 board feet with a 1-inch thickness when applied correctly, offering excellent coverage and value.
  • Strong Adhesion: Bonds excellently to all common building materials without the need for mechanical fasteners.
  • Moisture & UV Resistance: The cured foam is moisture-resistant, helping to prevent mold growth. For outdoor applications, it is overpaintable and should be painted or coated to protect against UV discoloration.
  • Ozone-Friendly: Does not contain propellant gases harmful to the ozone layer.
  • Fast Curing: Features a skin time of 5±2 minutes and a cutting time of ≤40 minutes, with full cure achieved in 24 hours.
  • Acoustic Performance: Contributes to noise reduction with an acoustic insulation rating of 48.8 dB at 1600Hz (EN ISO 717-1). Helps foster a calmer, more comfortable environment for your home or business.
Application Areas
  • Buildings & Houses: Roofs, attics, facades, foundations, basements, floors, interior walls, inter-floor overlappings, interior partitions, ceilings, and cellars.
  • Structural Elements: Balconies, loggias, doors, window slopes, pipes, canals, and tank-like round surfaces.
  • Vehicles: Car bodies, car trailers, boats, yachts, vessels, and all types of sea vehicles.
Application Instructions for Optimal Performance

1. PREP LIKE A PRO: Make sure the surface is clean, dry, and free of dust, oil, or debris. For temperatures above 32°F, lightly mist the surface with water. This simple step is crucial for improving adhesion and speeding up the curing process, ensuring you get the best coverage from your foam.

2. SUIT UP SMART: Safety isn’t optional. Wear gloves, goggles, and mask to protect yourself while working with the foam.

3. CHOOSE YOUR WEAPON: Select the right nozzle for your project:

  • Tip A – For vertical surfaces like walls and gaps.
  • Tip B – For horizontal surfaces like ceilings.

Press firmly until the tip clicks securely into place.

4. LOCK & LOAD: Bring the can to room temperature (around 68°F) for at least 24 hours before use. This ensures stable pressure, smooth spraying, consistent foam expansion, and a denser, higher-quality application.

  • Shake vigorously for at least 30 seconds before spraying to ensure a consistent and dense foam.
  • If the can is too cold or too hot, immerse it in warm or cold water, or leave it at room temperature until it reaches room temperature.

Attach the can & ready to fire!

5. SPRAY IN LAYERS:

  • Hold the can upside down during application.
  • Maintain the right distance : 12–18 inches from walls and 6–8 inches from ceilings.
  • Apply in thin layers : For a total thickness of 2 inches, use at least 3 layers. Avoid overfilling in one pass.
  • Shake the can between applications for even, high-quality coverage.

6. CLEAN LIKE A PRO

  • Wipe the gun and nozzle immediately after use.
  • Use Kraken Bond Foam Cleaner for fresh foam.
  • Once cured, foam can only be removed mechanically.
  • Protect cured foam from UV rays by covering it with plaster, paint, or another coating.

7. HELPFUL TIPS:

  • Every can comes with two replacement tips for convenience.
  • For consistent results, test spray on a scrap surface first.
  • Roof Application Tip: For best adhesion on roofs, clean the roof deck thoroughly and lightly mist the surface with water when temperatures are above 32°F. If applied too close or too heavily, foam can bounce off the surface instead of bonding properly. Keep the recommended 6–8 inch distance from the roof deck and apply with the gun set appropriately for a controlled output. Dust, loose granules, oily spots, skipping the water mist step, or spraying too close may reduce adhesion or cause foam separation.
  • Contact support promptly for troubleshooting if coverage or expansion seems below standard.

Great product, fast and easy

Great product. Shipped fast with instructions you can understand. Went on without an issue covering about the 20board feet they advertise. Did my garage in a few hours and easy clean up with the cleaning fluid.
Does take some skill to get it the same thickness all over so starting I have spots 3 inches thick and some 1 inch, even had to trim a few places that expanded beyond the 2x4.

It says easy to use as tying your shoes

Incredibly easy to use great coverage not a single issue. It says easy to use as tying your shoes. I’m a first time user a little nervous going in, but as soon as you squeeze the trigger, you say I got this

If hardly any mess goes exactly where you point the gun

Fantastic Product!

Fantastic product and very easy to use. I used it to insulate my mobile deer hunting blind. I was a little worried that it wasn't going to stick to the Tyvek wrap, but it did with no problems. Coverage was great and the cans lasted longer than I thought they would. I will definitely be a customer for life and I would highly recommend to anyone!

Spray Foam a metal building

I was hesitant about using this, I'm spraying a 26x22 metal building and didn't want to pay the big money to have it done. So, I bought 12 cans just to try it out.
It took a couple of cans to get the hang of it, I'm very pleased so far.
I have ordered 12 more cans, I'm sure I'll need 100 + cans.
One benefit of doing it this way is as I have the money and or time, I can keep buying 12 or more cans until I get it done.

Was easier to apply than I thought

Was easier to apply than I thought. Cleaning was very easy with the added cleaner cans.

Worked amazing

Used this to insulate the space between the ceiling and the wall right above a two-car garage door. It worked exactly as described, and I was surprised how easy it was! It took more time to move the ladder around and get stuff out of the way in the garage than it did to actually spray. Tips: Shake the can longer than 2 minutes. The better you shake the better the product comes out. Clean the nozzle and gun with the cleaner frequently and don't let it sit between cans. An actual respirator is highly recommended! Wear all the protective gear it comes with, especially the glasses. Take frequent open air breaks as you go. Overall I am impressed for a product I bought from a Facebook ad.

Fast Coat Spray foam

Overall happy with the outcome. I have purchased 2 each 48 can kits. The gun in the first kit did not perform as well as the gun in the second kit. It sprayed very blotchy. I never could get the spray pattern quite right. However the second gun worked really well. Picture of both guns and outcome attached.
I recommend this product. My project is a 40 x 60 metal shop, split in half. I can tell the difference in temperature already even though the one half is not complete yet.

Great product! Easy application and great coverage.

I used the Kraken FastCoat Fire Rated spray foam insulation to seal rim joists in our basement.

The kit ordered came with everything I needed to get started. The spray foam, cleaner, and gun. Application was seamless. Following the directions provided, it foam went on evenly and adhered to not only the wood in the joists, but also the metal ducts present in some of the joist bays.

I was actually pretty impressed with it, which is saying a lot for me. The application I used it for, sealing joist bays to be air tight, worked extremely well. Ordering another case of it to use to air seal my attic.

Best canned spray foam I have ever used, hands down

Best canned spray foam I have ever used, hands down.

Used with the Kraken gun and wall/ceiling tips, this was super effective at helping me air seal and insulate an attic space in my home that had been the cause of massive energy loss since this house was built.... in 1970.

With multiple attics and a crawlspace to handle, I'm coming back for another 24 pack right now.

Can this spray foam product be used in enclosed wall cavities behind existing drywall.

Kraken Bond - Monster of Tough Jobs

If there is an accessible cavity or gap behind the drywall, you can apply the spray foam using a long spray gun extension (24" or 40") to reach the enclosed space.

However, if you plan to inject foam by drilling small holes into the wall, this product is not suitable, as it is designed for open-surface application.

Please let us know more about your specific project, and we’d be happy to guide you further.
