3M All Weather Flashing Tape 8067 (4 inch x 75 ft) – Self-Adhesive Waterproof Flashing for Windows and Doors

All Weather Flashing Tape 8067: strong, flexible exterior sealing

3M All Weather Flashing Tape 8067 combines self-adhesive practicality with a durable backing designed for exterior openings. The acrylic adhesive grips materials firmly across temperature ranges and even bonds to damp surfaces. In real-world installations around windows, doors, thresholds, and vents, this tape can help create a continuous barrier against moisture infiltration while remaining unobtrusive under siding.

Its thin backing conforms closely to irregular edges, reducing buildup under trim and nails. The split paper release liner enables fast, precise placement, letting installers align joints and corners with confidence. The formulation is engineered to resist punctures and tears, while avoiding liquefying, bleeding, or softening when exposed to common sealants or high heat.

Key benefits at a glance

• Sticks and stays stuck: strong acrylic adhesive that bonds to common building materials without primers.
• Bonds across temperatures: effective from 0F to 176F (-18C to 80C) and even adheres to damp surfaces.
• Conforms and seals: thin backing reduces bulk under siding and helps block moisture intrusion around fasteners.
• Passes nail sealability: engineered to maintain seal through thermal cycling per AAMA 711-05.
• Resistant to liquid and heat: won't liquefy, bleed, or melt when in contact with many sealants or extreme heat.
• Easy to install in professional projects: split liner provides fast, precise positioning.

Where you can use it

The tape is recommended for sealing joints around sills, jambs, and heads on rectangular wood frame windows, and for flashing around other wall interruptions like thresholds, dryer vents, and hose bibs. When installed correctly as concealed flashing in vertical walls, it helps minimize moisture intrusion and water leaks, which can otherwise lead to costly problems.

Why choose 8067

• No priming required in many cases, saving time on install.
• Thin, durable backing fits into tight corners and under siding.
• Designed to maintain performance in varied climates and during heat cycles.
