3M 7100079743 All Weather Flashing Tape 8067 12in X 75ft

Product Description

The 3M 7100079743 is a self-adhesive all-weather flashing tape designed to create a moisture-resistant barrier at window and door rough openings in residential and commercial construction. The tape uses an aggressive acrylic adhesive bonded to a thin proprietary backing, giving it flexibility and reliable adhesion across a wide temperature range — from 0 degrees F up to 120 degrees F. This extended range makes it suitable where traditional asphaltic or butyl flashing tapes fail to bond properly. The 12-inch width and 75-foot roll length suit standard rough opening flashing applications. It is installed by waterproofing contractors, framers, and building envelope specialists.

This flashing tape is used in new construction and renovation projects to seal the perimeter of window and door openings against bulk water and air infiltration. The slit liner design allows for controlled, overlap-style application during installation. The tan color blends with common housewrap and sheathing materials. It is appropriate for wood, OSB, and common sheathing substrates typical in residential and light commercial framing. The tape is sold in roll form, with a minimum order quantity of 4 rolls per the supplier specification.

Installation Notes

Installation is typically performed by waterproofing technicians, framers, or building envelope contractors. Substrate surfaces should be clean, dry, and free of dust, oil, or loose material before tape application. Apply firm pressure across the full tape width to ensure full adhesive contact, paying particular attention to corners and transitions. Follow applicable building code requirements, including those referenced in the International Residential Code, for window and door flashing details.
