Protect your deck’s structural integrity from the ground up with the RW PP Deck Beam Tape, a premium-grade, self-adhesive flashing tape designed to shield deck beams and framing components from moisture, rot, and corrosion. With a generous 3.89-inch width and 50-foot roll length, this tape is ideal for covering wider surfaces like beams, rim joists, and ledger boards—ensuring long-lasting protection in even the harshest outdoor environments.

Built for Long-Term Durability

• Made with high-performance butyl adhesive, this tape forms a watertight seal that prevents water intrusion around fasteners and screw holes.
• The UV-resistant polyethylene top layer resists cracking, peeling, and degradation from sun exposure, ensuring performance over time.
• Acts as a barrier between treated lumber and metal hardware, helping to prevent galvanic corrosion and structural weakening.

Superior Moisture Protection

• Shields deck beams and framing from water infiltration, which can lead to wood rot, mold, and premature failure.
• Helps deck screws and fasteners hold stronger and longer by keeping the wood dry and intact.
• Ideal for use with pressure-treated, untreated, and composite wood.

Easy, Tool-Free Installation

• Peel-and-stick application—no special tools or fasteners required.
• Flexible and conformable to irregular surfaces, corners, and edges.
• Can be applied in both horizontal and vertical orientations.
