Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the patch color to the membrane for a consistent finished appearance. Install and weld the patch per Johns Manville PVC details, ensuring the T-joint area is clean and dry before heat welding. Keep a few patches on hand for detail work and fastener repairs during the main membrane installation.
Heat welding PVC patches involves hot-air equipment and hot material; follow the manufacturer's installation details and wear appropriate protective gear.
