3M 7000124877 All Weather Flashing Tape 8067 9in X 75ft

Product Description

The 3M 7000124877 is a self-adhesive all-weather flashing tape designed to seal window and door rough openings against moisture intrusion in residential and commercial construction. Sold as a 9-inch-wide by 75-foot roll with a slit liner for controlled application, it uses an aggressive acrylic adhesive bonded to a thin proprietary backing. The acrylic formula delivers adhesion in temperatures as low as 0 degrees F and as high as 120 degrees F, well beyond the serviceable range of traditional asphaltic or butyl flashing tapes. The tan color is compatible with common housewrap and sheathing substrates. Installers include general contractors, waterproofing specialists, and building envelope trades.

This tape is applied during the rough opening stage of window and door installation as part of the water-resistive barrier assembly. It is used to integrate flashing layers with housewrap and sheathing at sill plates, jambs, and head conditions. The slit liner allows the tape to be folded into corners or wrapped around rough opening edges without the backing tearing prematurely. Suitable for residential new construction and light commercial applications where a durable, weather-resistant seal is required at penetrations.

Key Features

• Aggressive acrylic adhesive bonds in extreme temperatures from 0 degrees F to 120 degrees F
• Exceeds the temperature performance range of standard asphaltic and butyl flashing tapes
• Thin proprietary backing conforms to corners, sills, and irregular surfaces
• Slit liner design supports precise placement and fold-in corner applications
• Self-adhesive construction requires no primers on most common sheathing substrates
• 9-inch width provides coverage for standard rough opening flashing conditions

Compatibility

Designed for use as a window and door rough opening flashing tape in residential and light commercial construction assemblies where a self-adhesive acrylic moisture barrier is required.

Installation Notes

Installation is typically performed by carpenters or building envelope contractors during the weather barrier phase of construction. Apply to clean, dry, and dust-free substrates for maximum adhesion. In cold-weather applications near the lower temperature limit, warming the roll and substrate surface prior to application improves bond formation. Follow local building codes and manufacturer sequencing guidelines for integration with housewrap and water-resistive barrier layers.
