The Gypsum Association commented at the September AWCI Construction Technology Committee meetings that the association has released a video that shows the proper way to repair damaged gypsum panels in a fire-resistive assembly. The video goes through a step-by-step process and can be found online at https://gypsum.org/2020/01/video-faq-test.
This is part of a library of podcasts developed by the GA that cover several topics specific to gypsum panels.
