3M All Weather Flashing Tape 8067 is a self-adhered waterproof flashing membrane designed for sealing around windows, doors, and other penetrations in exterior walls.
It uses an acrylic pressure-sensitive adhesive and a thin flexible backing intended to conform around corners, fasteners, and common building materials. The tape is designed to help reduce moisture intrusion when installed correctly as part of a building-envelope system.
The version covered here is a 3-inch x 75-foot roll of 3M All Weather Flashing Tape 8067.

Key Takeaways
- Designed for sealing around windows, doors, and other exterior-wall openings.
- Uses an acrylic pressure-sensitive adhesive.
- Designed to bond to many common building materials without primers or staples.
- Can be applied across a broad temperature range and is described as adhering to damp surfaces.
- Thin backing helps the tape conform around corners, nails, and staples.
- Buyer feedback commonly praises adhesion and sealing performance but sometimes mentions difficulty removing the release liner.
What 3M All Weather Flashing Tape 8067 Is Designed to Do
The tape is intended primarily for sealing around exterior-wall openings where water could otherwise enter the building envelope.
Typical uses include areas around window sills, jambs, and heads, as well as other non-roof penetrations such as thresholds, dryer vents, and hose bibs.
It is generally used as concealed flashing rather than as an exposed finished surface. Correct installation around overlapping materials and drainage paths remains important because flashing tape is only one part of a complete moisture-management system.

Important: the product information describes this tape as intended for industrial or occupational use rather than general consumer use. Check the current manufacturer and seller information before purchasing or installing it.
Installation and Placement
Surface preparation matters with any flashing tape. The installation surface should be suitable for adhesion and free from contaminants that could interfere with bonding.
3M states that the tape can bond to many common building materials without primers or staples and can adhere to damp surfaces within its specified application-temperature range.
The thin backing allows the tape to fit into corners and under siding with less buildup than thicker flashing products. It is also designed to conform around nails and staples.
A split paper release liner helps with positioning longer pieces, although buyer feedback commonly notes that the backing can sometimes tear or be difficult to remove cleanly.
Because the adhesive is aggressive, careful positioning is important. Once the tape makes firm contact with the surface, repositioning may be difficult.
Adhesion and Weather Resistance
The main advantage of the 3M 8067 flashing tape is its combination of strong adhesion and a flexible, relatively thin backing.
The product is designed to maintain adhesion across a broad range of environmental conditions and has a listed service-temperature range of -40°F to 240°F (-40°C to 116°C).
3M also states that the tape can resist UV exposure for up to 12 months. That can be useful during construction when flashing may remain exposed before siding or other exterior finishes are installed.
The product information also indicates compatibility with several common building sealant types, although compatibility should still be checked for the exact materials used in your project.
What Buyers Commonly Mention
Buyer feedback frequently highlights strong adhesion and good sealing performance. Some buyers report using the tape for air sealing, leak repairs, and other exterior-envelope applications.
Its flexibility is another commonly mentioned advantage, particularly when applying longer sections around corners and openings.
The biggest recurring complaint concerns the release liner. Some buyers report that it can tear or leave pieces behind during removal. Others mention that the strong adhesive makes incorrect placement difficult to correct.
Pros
- Strong acrylic pressure-sensitive adhesive.
- Designed for use around windows, doors, and exterior-wall penetrations.
- Thin and flexible enough to conform around corners and fasteners.
- Broad listed application and service-temperature ranges.
- Can bond to many common building materials without primers.
- Buyer feedback commonly praises adhesion and sealing performance.
Cons
- The strong adhesive can make repositioning difficult.
- The release liner can be awkward to remove and may tear.
- Correct flashing sequence and overlap still matter; the tape cannot compensate for poor installation.
- The product information describes it as intended for industrial or occupational use rather than general consumer use.
How It Compares With Other Butyl and Flashing Tapes
3M 8067 is aimed primarily at window, door, and exterior-wall flashing rather than deck-joist protection.
If you are working on an outdoor deck instead, products such as Viking Tape deck joist butyl tape or Heelos joist tape for decking are designed around protecting joists and beams from moisture rather than flashing windows and doors.
FAQ
What is 3M All Weather Flashing Tape 8067?
It is a self-adhered waterproof flashing membrane designed primarily for sealing around openings and penetrations in exterior walls.
Where is it commonly used?
Typical applications include windows, doors, thresholds, dryer vents, hose bibs, and other non-roof exterior-wall penetrations.
Does it require primer?
The product information states that it can bond to many common building materials without primer or staples. Surface condition and material compatibility still matter.
Can it be installed in cold weather?
The listed application surface-temperature range starts at 0°F (-18°C), making it suitable for colder installation conditions than many conventional flashing products.
Can it adhere to damp surfaces?
The product information states that the adhesive can bond to damp surfaces. Proper surface preparation and current manufacturer instructions should still be followed.
How large is the roll?
The version covered here is one roll measuring 3 inches wide by 75 feet long.
Final Thoughts
3M All Weather Flashing Tape 8067 is designed for demanding window, door, and exterior-wall flashing applications where strong adhesion and a thin flexible membrane are useful.
Its broad temperature range, ability to conform around fasteners, and compatibility with many building materials are its main strengths. The biggest practical drawback is its aggressive adhesive and sometimes troublesome release liner, both of which make careful positioning important.
