3M Company 2110NA Weatherproofing Tape 1.5in X 30ft

Product Description

The 3M COMPANY 2110NA is a transparent, adhesive weatherproofing tape designed for interior sealing applications. Measuring 1.5 inches wide and 30 feet in length, this tape provides moisture-resistant performance for sealing gaps and cracks around doors and windows. It also serves as a temporary repair solution for cracked window glass. HVAC, weatherization, and building maintenance technicians use it for quick, low-prep sealing tasks that require a clear, unobtrusive finish. The adhesive backing bonds to common interior surfaces without the need for primers or special tools.

This tape is suited for interior residential and light commercial applications. Primary use cases include sealing air gaps around door and window frames to reduce drafts and moisture infiltration, and providing short-term structural bridging over cracked glass panes until a permanent repair is made. It is a staple in weatherization kits used by HVAC service technicians and general maintenance crews working on building envelope improvements.

Installation Notes

Installation does not require licensed trade credentials, but weatherization technicians and HVAC service pros should ensure the application surface is clean, dry, and free of dust or oil before applying tape for maximum adhesion. No power shutoff is required for this product. Follow local building codes when using tape as part of an air-sealing scope on new or retrofit construction. This tape is rated for interior use only and should not be substituted for exterior-grade flashing or vapor-barrier materials.
