EternaBond RV RoofSeal 4" x 50' Self-Adhering Repair Tape White — UV-Stable, Flexible Leak Repair

EternaBond RV RoofSeal is a 4" x 50' self-adhering, UV-stable repair tape that creates a permanent, weatherproof seal on RV and mobile-home roofs.

This high-performance sealant tape combines MicroSealant Technology with a white, UV-stable backing to stop leaks, repair tears, and seal seams on a wide variety of roofing materials. The peel-off liner reveals a pressure-activated adhesive that bonds to most common substrates (excluding silicone) and forms an air-, moisture- and water-tight barrier. Made in the USA and engineered to remain flexible from extreme cold to hot conditions, this roll is sized for multiple repairs or longer runs along flashings and seams.

How does this tape stop roof leaks quickly?

The tape installs in one step: clean and dry the surface, remove the liner, press the tape into place and smooth to ensure full contact. The integrated primer-like microsealant wets the substrate and cures to a durable adhesive layer that resists lifting and water intrusion. Because it is ready-to-stick, most repairs take only minutes without special tools.

• Peel-and-stick application with pressure-activated microsealant
• Forms immediate water-tight barrier over holes, seams, and tears
• Works on patch repairs and continuous seam coverage

Which roofing materials and surfaces does it bond to?

RV RoofSeal adheres to a wide range of roofing and building substrates except silicone surfaces. It is formulated for EPDM, TPO, many PVC systems, CSPE/Hypalon, modified bitumen, all metals, shingles, tiles, and common building materials such as wood, concrete, and fiberglass. That versatility makes it useful on roofs, flashings, gutters, skylights and more.

• Compatible with EPDM, TPO, most PVC, Hypalon, and modified bitumen
• Adheres to metal roofs, aluminum, galvanized steel, and gutters
• Also bonds to wood, concrete, OSB, fiberglass, and masonry

Can this tape handle extreme weather and movement?

Yes — the product is engineered to flex, expand and contract with temperature changes so it holds through freeze-thaw cycles and hot summer heat. It remains workable and adhesive in temperatures as low as -20°F, and the white UV-stable backing reduces heat absorption on rooftops. The result is long-term performance without brittle failure or peeling when properly applied.

• Flexes with thermal movement to maintain the seal
• Operates in cold conditions down to -20°F
• White UV-stable face reduces sun degradation and heat gain

How do I prepare and apply the 4" x 50' roll for best results?

Start with a clean, dry surface and remove loose debris or old sealants; EternaClean or a compatible cleaner helps prepare the area. Measure and cut the length needed, peel back the liner gradually, press the tape firmly and roll or squeegee to eliminate trapped air. Overlap seams where necessary and use continuous, full-surface contact for a reliable, long-lasting repair.

• Clean and dry surface; use a compatible cleaner if needed
• Cut to length, remove liner as you apply, press firmly
• Roll or squeegee to ensure full adhesion and remove air pockets
