FireWall is a water based acrylic polymer, loaded with heat reducing ceramic spheres and thermal insulating glass beads. When applied to the sheet metal panels of a passenger vehicles, Firewall will reduce heat transfer and help keep the  passenger compartment cool and comfortable. FireWall Ceramic Coating is loaded with vacuum sealed fillers, making it flame retardant in addition to being non-toxic and waterproof. Easy to apply with brush, roller or spray gun!

 

  • High heat, water based viscoelastic polymer designed for thermal insulation
  • Durable ceramic coating that's easy to clean up with water
  • Apply in 1mm layers to the recommended 2 to 3mm of total thickness
  • Excellent for any metal surface you want to protect from high temperatures (firewall, hood, undercarriage)
  • Temperature rated up to 400°F sustained, 500°F intermittent
  • Apply with a brush, roller, or spray gun 
  • Made in the USA

 

  

Product Usage Tips

  • Always keep a 2" air gap between FireWall and the heat source
  • Clean up with water within 30 minutes of application. Do not wait longer or FireWall will dry.
  • If applying multiple layers of FireWall, wait 30-60 minutes for the product to cure and change color from blue to black.
  • FireWall is designed to adhere to metal. Do not apply to plastic or fiberglass without the proper primer. If applying to a high gloss wax coat, you must sand down and apply a primer.
  • Do not freeze FireWall! If it does freeze, do not mix, shake, or move until it has completely thawed.
  • Wait 24-36 hours (depending on humidity) before putting upholstery back in the vehicle. Wait 7 to 10 days before painting or applying a bed liner.
  • As FireWall cures, its deadening properties will continue to increase. Vibration damping doubles from 4 hours --> 48 hours, and continues improving for 7 days.
  • FireWall contains rust inhibitors and dries with a seamless finish. It is water resistant and and solvent resistant.
  • Shelf life of 1 year when stored at room temperature

Application Instructions

  1. After upholstery or carpet is out, remove loose debris, rust, dirt, and waxy oils to insure a solid contact surface. Most new cars will not need much prep work, while some older vehicles should be treated with denatured alcohol.
  2. Mask off all interior and exterior areas of the car for overspray. Cover any mechanical or moving parts as well as wires and wire harnesses. If you don’t want to cover it in FireWall, mask it off.
  3. FireWall can be applied with a brush or with the Second Skin spray gun. The product will perform either way. Regardless of application method, the goal is to get to a total thickness of 2 to 3 mm. At a minimum, Firewall must measure 1mm thick to stop heat transfer (slightly thicker than a credit card). We recommend 2mm-3mm thick. At 2mm thick, 1 gallon will cover 20 square feet.
  4. Apply in layers of no more than 1mm at a time. If FireWall runs, you are applying it too thick. After 30 to 60 minutes (depending on temperature and humidity), FireWall should be dry to the touch and safe to add another layer.
  5. Most regular paint guns will not be able to spray Firewall due to the extremely viscous consistency. We suggest using a HVLP undercoating gun or the Second Skin spray gun. Whichever you use, the nozzle and stem must be 2mm.
  6. FireWall is easy to clean up with water if done within 30 minutes of applying the product.
  7. Allow 24-36 hours before another product or upholstery is installed. FireWall may be painted or covered with a bed liner after 10 days.

 

Spraying is the most efficient application method to choose for coating irregular surfaces. Prior to spraying FireWall, everything close to the panel should be covered and masked off for overspray protection. For an airless sprayer, you want at least 3000 psi, a 0.019” nozzle, and a hose less than 1 yard long. If you use our Second Skin spray gun, we recommend an air compressor with 5-6.5 cfm and 50-80 psi. A 6-gallon tank is ideal. If your compressor is not strong enough, try elevating the bucket higher than the gun and let gravity help out.

Brushing is the more popular choice for applying FireWall. Simply dip a paint brush into the bucket and paint FireWall on any metal panel that vibrates.

 

 

FAQ

What is the difference between Spectrum & Firewall?
Spectrum is a dense product designed to damp lower-frequency structure borne noises. While it provides some thermal insulation, its primary purpose is to stop metal from vibrating. Firewall is much lighter. The key ingredients are loads of extremely small glass spheres that are very poor conductors of heat. While Firewall Ceramic Coating will provide some vibration damping, its primary purpose is heat insulation. 

You can use both products together (apply Spectrum as the base layer), or choose between the two depending on whether your focus is sound or heat.
