Spectrum™ Spray On Deadener

Acoustic Loss Factor @ 200Hz

• Clean up with water within 30 minutes of application. Do not wait longer or Spectrum™ will dry. Always clean the spray gun between coats by running water through it.
• If applying multiple layers of Spectrum™, wait 30-60 minutes for the product to cure and change color from blue to black.
• The temperature must be above 50°F for the entire 24 hours cure period after applying Spectrum™. Dry times increase with low temperatures and high humidity.
• Spectrum™ 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 Spectrum! 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 Spectrum™ cures, its deadening properties will continue to increase. Vibration damping doubles from 4 hours → 48 hours, and continues improving for 7 days.
• Spectrum™ contains rust inhibitors and dries with a seamless finish. It is water resistant and safe to use for boat soundproofing.
• Spectrum™ is not a bed liner. Even after it has cured, it can be damaged by heavy impact.
• Shelf life of 1 year when stored at room temperature.
• Wheel well sound deadening applications require about 2 gallons for all 4 wheel wells. (all vehicles) and helps a good bit with soundproofing car road noise.
• Use Spectrum™ anywhere you have vibrating metal to soundproof the structure, like a car or soundproof shed roof.

1. After upholstery or carpet is out, remove loose debris, rust, dirt, and waxy oils to insure a solid contact surface. Clean with denatured alcohol.
2. If spraying, mask off all interior and exterior areas of the car for overspray. Cover mechanical parts, wires, and wire harnesses.
3. Spectrum™ can be applied with a brush or with the Second Skin spray gun.
4. The recommended total thickness is 2 to 3 mm for a vehicle. Some commercial applications can do 1mm total thickness.
5. Apply in 1mm layers. If Spectrum runs, you are applying it too thick. Always clean the spray gun between layers by running water through it until there's no dark pigment.
6. After 60 to 90 minutes (depending on temperature and humidity), Spectrum™ will skin over and change colors from blue to black. Once Spectrum™ is black, it's safe to add another layer.
7. Most regular paint guns will not be able to spray Spectrum™ due to the extremely viscous consistency. We suggest using a HVLP undercoating gun or the Second Skin spray gun. The nozzle and stem must be 2mm.
8. Spectrum™ is easy to clean up with water if done within 30 minutes of applying the product.
9. Allow 24-36 hours before another product or upholstery is installed. Spectrum™ may be painted or covered with a bed liner after 10 days.
