3M 7100028214 Sealing Tape Tan 12 Inch Width

Product Description

The 3M 7100028214 is a high-tack acrylic sealing tape with a proprietary film backing and split release liner, designed for use on difficult-to-stick and damp surfaces. The aggressive acrylic adhesive maintains bond strength across both low and high application temperatures and will not melt or stain when exposed to heat. The backing is thin, conformable, and puncture-resistant, making it suitable for corner applications and irregular surfaces. This tape is installed by weatherization contractors, insulation crews, and building envelope technicians on residential and light commercial projects.

This sealing tape is used wherever an air barrier or moisture barrier is required in building envelope assemblies. It performs on damp substrates where standard tapes fail to adhere. The waterproof membrane construction blocks moisture infiltration, and the UV-resistant formulation holds up to 12 months of UV exposure before permanent cladding or covering is applied. The split release liner allows fast, accurate placement during installation. It is sold by the roll and is commonly applied at seams, penetrations, and transitions in wall and roof assemblies.

Key Features

• High-tack acrylic adhesive bonds to difficult and damp surfaces where standard tapes fail
• Waterproof membrane provides a moisture barrier at seams and transitions
• Creates an air barrier to reduce infiltration in building envelope assemblies
• UV-resistant formulation rated for up to 12 months of exposure
• Adhesive does not melt or stain at elevated temperatures
• Thin, conformable backing fits into corners and around irregular geometry
• Split release liner enables fast application with accurate tape positioning

Compatibility

Designed for use on building envelope assemblies requiring air and moisture sealing, including damp, low-porosity, and difficult-to-adhere surfaces typical of residential and commercial construction.

Installation Notes

Installation is performed by weatherization technicians, insulation contractors, and building envelope crews. Surfaces should be as clean and dry as conditions allow before tape application, though this product is formulated to adhere on damp substrates. Ensure the split liner is removed cleanly before pressing the tape into place. Follow applicable building energy codes for air barrier continuity requirements.
