EternaBond RoofSeal RV roof repair tape 4in x 25ft White — 35 mil, UV-stable, one-step waterproof seal

EternaBond RoofSeal White 4" x 25' is a one-step, UV-stable repair tape that creates a durable, waterproof and airtight MicroSealant for RV and building roofs.

Designed for quick repairs and lasting protection, this 35 mil total-thickness tape combines an aluminum backing with an advanced MicroSealant layer to bond to EPDM, TPO, Hypalon, metal, wood, fiberglass and more. It forms a flexible, weather-resistant barrier without primers, solvents or additional sealants, remaining pliable at very low temperatures and resisting UV degradation for exterior applications.

How does EternaBond RoofSeal stop leaks fast?

The tape adheres instantly to clean, dry surfaces and creates a continuous, moisture- and air-tight barrier thanks to its MicroSealant adhesive. One-pass application eliminates the need for messy compounds or multiple layers, delivering immediate protection against water infiltration.

• Peel-and-stick installation for rapid coverage
• Aluminum backing plus MicroSealant for long-term sealing
• Works on irregular shapes and seams without caulking
• Suitable for emergency patching or planned maintenance

Will this tape handle sun, heat and cold?

Yes — the product was engineered for exterior durability. Its UV-stable aluminum surface resists sun degradation while the MicroSealant remains flexible down to -57°C (-70°F), so it withstands wide temperature swings without cracking or losing adhesion.

• UV-stable backing resists breakdown from direct sunlight
• Maintains flexibility in extreme cold to prevent splits
• Resists thermal cycling and outdoor weathering
• Built for long-term exposure on roofs, boats and trailers

What surfaces and projects are compatible with this tape?

EternaBond RoofSeal bonds to a broad range of common roofing and exterior materials, making it a versatile choice for RVs, metal buildings, boats and more. It performs well on both flat and curved substrates and is often used for seam repairs, flashing coverage and drain pan sealing.

• Compatible with EPDM, TPO, Hypalon, aluminum and galvanized steel
• Adheres to wood, painted surfaces and fiberglass hulls or decks
• Useful for flashing, seam coverage, patching and drain pans
• Works on vertical and horizontal surfaces, small patches to long runs

How easy is it to apply and maintain?

Application is straightforward: measure, cut, peel the liner and press firmly into place. No primers, mixing or cleanup of solvents are required, and the tape creates a protective abrasion-resistant surface that reduces follow-up maintenance.

• One-step installation—no trays or paste required
• Hand-roll or squeegee to ensure full contact and remove air pockets
• No additional sealants needed for a waterproof finish
• Low-maintenance once installed; inspect periodically for debris
