    Mastic Tape?

    I'm sure most of you are talking about Mastic Tape,...Very easy to work with and extreamly difficult to remove, an excellent product.

    Mastic tape, aka rollmastic, aka butyl tape.

    Basically it is foil tape with a thick butyl rubber adhesive. Fairly expensive.
    I use it for sealing equipment connections, like furnace to coil, and for sealing plenum and transition connections to the unit. Its fast, won't fall off ever, and when I wrap the plenum/transitions with duct wrap, there isn't an issue with taping the vapor barrier to the unit like there would be if we used brush on mastic.

    If more government is the answer, then it's a really stupid question.
