3M All Weather Flashing Tape 8067 – Waterproof 6 in x 75 ft Tape for Doors & Windows

Overview

3M All Weather Flashing Tape 8067 is a self‑adhered, waterproof flashing membrane designed to seal around openings and penetrations in exterior walls. Its acrylic pressure sensitive adhesive bonds aggressively across a broad temperature range and even on damp surfaces, helping you create durable seals without primers or staples. The thin backing conforms neatly around nails and fasteners, reducing buildup under siding while delivering a reliable moisture barrier.

Key benefits

• Sticks and stays stuck: A unique acrylic adhesive sticks securely to windows, doors, and other openings, simplifying installation.
• Bonds across temperatures: Effective from 0 F (-18 C) up to 176 F (80 C) and even on damp substrates, expanding installation options.
• Conforms and seals: The thin backing flexes around nails and staples to minimize gaps under siding.
• Nail sealability certified: Meets nail sealability expectations per AAMA 711‑05, helping manage long‑term performance through thermal cycles.
• Resistant to bleed and melt: Designed not to liquefy or bleed when in contact with many common sealants or under high heat.
• Split liner for speed: The split paper release liner enables fast, precise positioning and placement.

Recommended uses and real‑world scenarios

• Sealing joints around sills, jambs, and heads of rectangular windows in wood frame construction.
• Providing concealed flashing around other wall interruptions such as thresholds, dryer vents, and hose bibs in non‑roof areas.
• Using as a flashing layer in vertical walls for moisture management and to help prevent water intrusion behind siding.

Performance and compatibility

The 0.25 mm film backing combines with a robust acrylic adhesive to resist punctures and tears while remaining thin enough to fit into corners and under siding. The backing effectively seals around nails and staples, helping to minimize moisture intrusion even after thermal cycling. It is compatible with many building sealants and shows no adverse reaction with common sealants such as synthetic rubber, butyl, polyurethane, silicone, and silane terminated hybrids.
