3M Company 2245-A Heavy Duty All Weather Duct Tape

Product Description

The 3M COMPANY 2245-A is a heavy duty all-weather duct tape engineered for demanding indoor and outdoor applications. The tape measures 2 inches wide by 45 yards long and features a gray and silver backing that is both waterproof and UV-resistant. It tears easily by hand and conforms smoothly to curved surfaces without lifting or bubbling. The adhesive holds firmly under extreme temperature and moisture conditions, resisting the drying, cracking, and peeling that sunlight and outdoor exposure typically cause. Licensed trades and maintenance professionals rely on it for heavy duty patching, sealing, and emergency repairs where a standard tape would fail prematurely.

This tape is suited for residential and commercial maintenance work, HVAC duct sealing in accessible locations, plumbing wrap, electrical conduit bundling, and general-purpose repair tasks in environments that see direct sun, rain, or wide temperature swings. The all-weather formulation extends service life significantly compared to standard duct tape grades, making it practical for exterior repairs that need to last through multiple seasons without re-application.

Key Features

• 2 inches wide by 45 yards long per roll for extended coverage
• Waterproof backing resists moisture penetration in indoor and outdoor use
• UV-resistant formulation resists drying, cracking, and peeling from sunlight exposure
• Tears easily by hand without a cutting tool, speeding up field repairs
• Conforms to curved and irregular surfaces for consistent adhesion
• Rated for extreme conditions including high heat, cold, and direct weather exposure

Compatibility

Designed as a general-purpose heavy duty duct tape for indoor and outdoor repair, patching, and sealing applications across HVAC, plumbing, electrical, and building maintenance trades.

Installation Notes

Clean and dry the surface before application to ensure full adhesive contact. Apply with firm, even pressure across the entire tape width, especially on curved or irregular surfaces. For HVAC duct applications, verify local mechanical codes regarding approved taping methods and materials, as some jurisdictions require UL 181-listed tapes for air distribution systems. Remove the roll from direct heat sources during storage to preserve adhesive performance.
