Meet Eternabond Roof Seal Tape White 4" x 50' (15.2 m) — a single, self-bonding repair solution designed to seal roof joints, seams, tears, flashings, copings, skylights, gutters, and more. Built for real-world roof maintenance, it’s especially effective for restoring and patching roofs on mobile homes and RVs, but its versatility fits a wide range of surfaces and projects.

• Multi-use versatility: Perfect for metal buildings, trailer and RV roofs and sides, drain pans, drain pipes, boats, and canoes. It’s designed to work beyond traditional roofs, giving you a single tape that covers many repair needs.
• Bonds to itself — no extra sealant required: The aluminum backing, combined with a layer of advanced MicroSealant, forms a waterproof, moisture- and air-tight barrier. Since it bonds to itself, you can cut, fold, and contour the tape around irregular edges for a seamless seal.
• Wide surface compatibility: Bonds to EPDM, TPO, Hypalon, aluminum, galvanized steel, wood, and fiberglass, enabling reliable repairs on a broad spectrum of roof materials.
• Durable, UV-resistant and flexible: The tape provides a tough, abrasion- and corrosion-resistant surface with excellent UV stability. It remains flexible down to -57°C (-70°F), maintaining a seal in fluctuating temperatures and sun exposure.
• One-step, mess-free application: No trays, messy solvents, or additional adhesives. Simply apply the tape to a prepared surface for a fast, lasting seal.

Surface preparation

• The surface must be clean and dry. Remove moisture, dust, dirt, and other foreign matter.
• If oil or grease is present, remove with Eternaprime (RVO699) or a non-residue cleaner such as acetone or lacquer thinner.
• Rinse away salt and other contaminants to ensure optimal adhesion.

How to apply for best results

• Unroll the tape and cut to the length you need. Position it over the seam, tear, or target area.
• Press firmly to activate the bond. Because it sticks to itself, you can wrap edges and contours for a tight, continuous seal.
• Overlap any joints as needed to maintain a waterproof, air-tight barrier without gaps.

Whether you’re patching a leaky seam on an RV roof, restoring a corner flashing, sealing around a skylight, or protecting a drain area on a metal building, Eternabond Roof Seal Tape White 4" x 50' offers a dependable, long-lasting solution. Its self-bonding formula and robust backing take the guesswork out of roof repairs, delivering a professional-grade seal with minimal effort.
