3M All Weather Flashing Tape 8067 – Waterproof Window & Door Flashing, 3 in x 75 ft

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 sticks quickly and stays put across a wide temperature range, eliminating the need for primers or staples in many projects. It bonds to most common building materials from 0F to 176F (-18C to 80C) and even adheres to damp surfaces, giving you flexible installation options in changing conditions. The thin backing conforms smoothly around nails and staples, reducing bulk under siding while forming a continuous moisture barrier that stays tight over time. The tape’s composition resists common sealants from dissolving or bleeding, even under heat, helping maintain a clean edge that’s easier to trim and finish.

Key benefits

• STICKS AND STAYS STUCK: The unique acrylic adhesive grips quickly and remains secure without primers or staples, simplifying installation.
• BONDS TO MOST COMMON MATERIALS: Works from 0F to 176F and even adheres to damp substrates, offering flexibility across projects.
• CONFORMS AND SEALS: Thin backing follows irregular edges to create a tight seal around nails and staples with less bulk under siding.
• PASSES NAIL SEALABILITY: Designed to maintain seal integrity during thermal cycling, meeting criteria in AAMA 711-05.
• RESISTS LIQUEFY, BLEED, OR MELT: Won’t liquefy or bleed when in contact with many sealants or high temperatures, reducing failure risks.
• EASY TO APPLY: Split paper release liner enables fast, accurate positioning for efficient installs.

Real-world performance and guidance

In outdoor projects, the tape acts as a reliable moisture barrier around openings while remaining adaptable to seasonal shifts. Its ability to adhere to damp surfaces helps when materials aren’t perfectly dry, and the thin backing makes it easier to work around corners and under siding. The product is intended for industrial and occupational use, offering a robust option for exterior flashing in wood frame construction. For best results, apply to clean, dry surfaces within the recommended temperature range and press firmly to ensure solid contact along the full width of the tape.

Recommended uses

• Sealing joints around sills, jambs and heads of rectangular windows in wood frame construction
• Sealing around other wall interruptions in non-roof areas such as thresholds, dryer vents and hose bibs
• When installed properly as concealed flashing in vertical walls, it helps prevent moisture intrusion behind siding
