EternaBond RoofSeal Gray 2in x 50ft MicroSealant RV Tape | UV Stable, One-Step Waterproof Seal

Overview

EternaBond RoofSeal Gray is a 2 inch by 50 foot roll of MicroSealant tape designed for quick, reliable roof repairs. With a 35 mil total thickness and a robust aluminum backing, this one-step system aims to deliver a waterproof, moisture-resistant, and airtight barrier for RVs, trailers, boats, and more. The combination of MicroSealant and backing is engineered to stay flexible across a wide range of temperatures, providing a practical solution for on-the-go maintenance and seasonal upkeep.

Versatility is a core strength. This tape is described as multi-use, capable of bonding to a broad spectrum of surfaces typically found on roofs and related components. It is particularly compatible with common roof materials such as EPDM, TPO, Hypalon, aluminum, galvanized steel, wood, and fiberglass, making it suitable for metal buildings, trailer and RV roofs and sides, drain pans, drain pipes, boats, and canoes.

Key Benefits

• Multi-use across surfaces and applications, including trailer/RV roofs, metal buildings, and portable watercraft.
• No extra sealing steps required thanks to an aluminum backing paired with MicroSealant for a moisture- and air-tight barrier.
• Durable, protective coating designed to resist abrasion and corrosion where a repair is needed.
• Excellent UV resistance helps limit deterioration under sun exposure and temperature fluctuations.
• Simple, one-step repair process with no trays or messy solvents, reducing cleanup time after installation.
• Flexible down to -57°C (-70°F), maintaining seal integrity in cold or variable weather.

How and Where to Use

Apply this tape to surfaces that require a dependable seal against air and water intrusion. Common scenarios include roof seams, around vents, and other joints where moisture management is critical. Because the system is described as one-step and adhesive-backed, it encourages quick applications without the need for additional adhesives or tools.

Recommended surfaces include EPDM, TPO, Hypalon, aluminum, galvanized steel, wood, and fiberglass. This expands potential use from RV roof repairs to repairs on marine equipment, drain areas, and light-duty exterior seams. For best results, ensure the target surface is clean and dry before application, and press the tape firmly to establish a consistent seal. While the data highlights several benefits, individual outcomes depend on surface preparation and environmental conditions.
