Installation Notes

Surface preparation is critical for tape adhesion - clean and dry the substrate before application to remove dust, oil, and moisture. No special tools are required beyond a cutting implement and a roller or applicator to ensure full contact with the surface. Follow local building codes and HVAC industry standards when sealing ductwork, as some jurisdictions require UL-listed tapes for specific duct applications. Verify that this product meets the requirements of the specific code or specification for your job before installation.
