Using Duct Mastic for general air sealing
At a building conference last week, one of the sessions was on air sealing in attics. The presenter explained that duct mastic is a good option for sealing top plates and around drywall in knee walls. I had never thought of using duct mastic for this purpose, but it does seem to make sense.
Is anyone else using duct mastic for this application? What has been your experience?
