Installation Instructions
Installation Instructions
- Clean up with water within 30 minutes of application. Do not wait longer or Spectrumâ„¢ will dry. Always clean the spray gun between coats by running water through it.
- If applying multiple layers of Spectrumâ„¢, wait 30-60 minutes for the product to cure and change color from blue to black.
- It must be above 50°F for the entire 24 hours cure period after applying Spectrum™. Dry times increase with low temperatures and high humidity. If you expect longer than usual dry times, we recommend thinner layers (0.5mm instead of 1mm) to the same total thickness.
- Spectrumâ„¢ 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 bedliner.
- As Spectrum cures, its deadening properties will continue to increase. Vibration damping doubles from 4 hours --> 48 hours, and continues improving for 7 days.
- Spectrumâ„¢ 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
