About EternaBond®

EternaBond® is a brand built on a singular promise: when you make a repair, it stays repaired. A product line under the H.B. Fuller family of adhesive brands, EternaBond has earned a reputation as one of the most trusted names in high-performance sealing tape and sealant technology. EternaBond® is recognized as a highly reliable sealant method for roof repair and leak protection, creating an air-tight, waterproof barrier with a permanent bond. Whether you’re a professional technician or a dedicated DIYer, EternaBond products are engineered to deliver confidence in demanding environments.

MicroSealant® Technology: The EternaBond Difference

At the heart of every EternaBond product is the brand’s proprietary MicroSealant® Technology. EternaBond tapes are designed with proprietary MicroSealant, which bonds instantly to most materials, creating a watertight barrier that resists extreme temperatures, UV rays, and moisture. This isn’t simply an adhesive tape — it’s a complete sealing system in a roll.

RoofSeal™ utilizes EternaBond®’s advanced MicroSealant® Technology, a 100% solids formulation of synthetic resins, thermoplastics, and non-curing rubber with a built-in primer. This means no need for additional primers or prep chemicals in most applications — just clean the surface and apply.

EternaBond products bond to almost any surface, including metal, wood, fiberglass, and more, creating a reliable, long-term seal. Proudly manufactured in the USA, EternaBond tapes are trusted for their durability and simplicity, allowing professionals and DIYers alike to tackle repairs and maintenance with confidence.

Built for the Toughest Conditions

EternaBond is a go-to solution for RV owners, fleet operators, roofers, and outdoor enthusiasts who need repairs that hold up season after season. If installed properly, EternaBond® can last 20+ years. It’s engineered for permanent repairs and resists UV, moisture, and temperature changes, and creates a 100% waterproof and airtight seal using MicroSealant® technology.

EternaBond remains flexible and effective in temperatures as low as -57°C (-70°F), ensuring reliable performance in harsh weather. From scorching summer heat to subzero winter conditions, the bond does not fail.

The brand’s Self-Fusing Repair Tape lineup is the cornerstone of the EternaBond catalog, covering everything from narrow emergency patch rolls to wide-format roof repair tapes in multiple colors and substrates. For applications requiring a more fluid-applied solution, EternaBond also offers Caulks & Sealants designed to complement their tape products and seal joints, seams, and gaps where tape alone may not reach.

Versatile Applications Across Industries

EternaBond is perfect for roofs, RVs, gutters, flashing, and windows, as well as a variety of surfaces such as metal, rubber, wood, and vinyl. EternaBond® RVSeal is commonly used for one-step sealing of roof joints in RVs, trucks, trailers, and buses. The ease of installation — a simple peel-and-stick process — makes it approachable for virtually any skill level while delivering results that meet professional standards.
