Deck Flash Barrier Tape


Color/Finish: Select a color

Whether you’re using treated, untreated, or synthetic decking, our Deck Flashing Tapes will greatly extend the life of your deck. Our products keep out moisture by sealing the joists of your deck, preventing rot, mold, and water damage.

When applied to deck joists, DECK FLASH BARRIER creates a waterproof membrane that prevents wood rot and decay caused by the accumulation of moisture under the decking boards. DECK FLASH BARRIER self-seals around screws and nails blocking the primary pathway of water into lumber.

When installed around the base of a post, DECK FLASH BARRIER will prevent wood rot and decay, dramatically extending the life of your lumber.

When DECK FLASH BARRIER is placed between treated lumber and metal surfaces it creates a physical barrier that prevents the corrosion of metal caused by contact with the chemicals in treated lumber.

DECK FLASH BARRIER is recommended for both treated and untreated lumber.
