Cofair 12″ x 25′ Deck Flashing Barrier – Schillings

Deck Flash Barrier is the ideal self-adhesive flashing to help protect your deck ledger boards. In addition to preventing wood rot in the ledger board itself, it also protects the adjoining structure by preventing moisture from entering behind the mounted ledger board. When installing wood posts, wrap them at the ground level with Deck Flash Barrier to help prevent wood rot and failure. Deck Flash Barrier’s tough, slip-resistant polyethylene material and super grip adhesive create a waterproof membrane that seals around the screw and nail holes, blocking the main paths of water infiltration.
