FrogTape Pro Grade Deck & Joist Flashing Tape — 4 in x 50 ft, UV-Resistant

Overview

FrogTape Pro Grade Deck and Joist Flashing Tape delivers a ready-made waterproof layer for deck joists, stair stringers, and ledger boards. Its linerless design helps reduce waste and simplifies outdoor use, while the advanced adhesive and conformable film backing move with wood components through edges and corners. This tape is engineered for durability in real-world conditions and is formulated to work alongside caulks and sealants without unintended reactions.

Built to perform across varied climates, the tape resists moisture intrusion, maintains adhesion in outdoor environments, and stays effective across a wide temperature span. The combination of ShurGRIP acrylic adhesive and a flexible backing supports a long-lasting seal on common decking substrates, including pressure-treated wood, OSB, and concrete. The product is VOC-free and designed to complement existing flashing details without adding solvents to the job.
