    Hardcast Mastic Tape

    Posted by Jeff Davidson on Feb 16th 2022

    So much easier than a bucket of mastic sealant. Worth the price. I replaced all of my old, leaky ducts with flex-duct and used the mastic tape to seal new takeoffs to the main trunk line. Easy peazy, and thanks to Michael for the useful how-to video. Don't drop this in the dirt! When working beneath the house I kept the roll in a bucket that wouldn't tip over.
