(1 customer review)

$ 16.50$ 95.00

Water-resistant tape used for sealing flashing, joists, ledgers, and underdecking, with peel-off backing.

While working with G-Tape, it will easily pull apart if sticky sides touch.

Unlike butyl-based tapes, G-tape will stick to surfaces even in extreme cold, and will not melt or slip in summer heat.

    Best part is that you can peel it back apart if you accidently stick it to itself. Butyl tape is ruined once it sticks to itself. We use the Gtape for other stuff besides just joist tape and flashing tape because its so sticky. 12″ tape also works great on mullions where you have to do horizontal blocking
