Self-Adhesive Deck Flash Barrier

Self-Adhesive Deck Flash Barrier

When applied to the top of deck joists, Deck Flash Barrier creates a waterproof membrane that prevents wood rot and decay caused by the accumulation of water under the decking boards. Deck Flash Barrier Super Grip Adhesive can now be installed at temperatures down to 25 deg. F. It self-seals around screws and nails, blocking a primary pathway for water infiltration in deck joists thus preventing wood rot. It also creates a physical barrier that prevents corrosion of the metal surface caused by contact with ACQ (Alkaline Copper Quat), CA-B (copper azole), ACZA (ammoniacal copper zinc arsenate) treated lumber. Deck Flash Barrier can be used to protect metal flashing and hangars, as well as deck plates, sill plates, and anywhere treated lumber is used. 3″ x 75′ roll.
