Installation Instructions

  • One-sided vs Two-sided: For porous materials or ceiling applications, we recommend spraying both the substrate and the material. When adhering non-porous to non-porous, a one sided application is acceptable.
  • Apply spray adhesive to both the material substrate with 80% to 100% coverage. For acoustic panels, leave a 2 to 3 inch gap around the perimeter.
  • Allow 2-4 minutes for it to "tack up".
  • Then press together firmly with as much pressure as practical to create the permanent bond.
  • The initial bond is strong enough to allow cutting and trimming, with maximum bond strength achieved in 1-3 days.
  • Each can will cover approximately 50 sq ft for a 1-sided application or 25 sq ft for a 2-sided application.
