EternaBond White RoofSeal is a 4" x 20' premium MicroSealant tape engineered to create a permanent, watertight repair on RVs, mobile homes, and rubber roofs.

Designed for fast, reliable leaks repairs and long-term protection, this white RoofSeal tape combines a high-performance adhesive backing with a reinforced polymer face. Cut from fresh master rolls to produce 20-foot lengths, the product is formulated to bond to a broad range of roofing materials — from EPDM and TPO to metal and PVC — creating an immediate seal without solvents or messy adhesives. It’s a professional-grade solution used by roof repair specialists and DIYers who want a durable, low-profile patch that resists weathering and UV exposure.

How does this tape stop roof leaks quickly?

The tape uses a MicroSealant adhesive that flows into surface irregularities, forming a continuous barrier over seams, rips, and penetrations. Applied directly over the damaged area, it adheres aggressively and cures without the need for primers in many applications.

• MicroSealant chemistry creates a gap-filling bond that resists water intrusion.
• Reinforced, weather-resistant face membrane prevents tearing and UV breakdown.
• Instant adhesion allows immediate protection; no long drying times.
• Works on seams, punctures, tears, flashing, and around fittings.

Which roofing materials will EternaBond RoofSeal bond to?

RoofSeal is formulated to adhere to a wide variety of surfaces commonly found on mobile homes, RVs, and buildings. While it bonds well to most substrates, surface preparation improves longevity and adhesion, especially on dirty or oxidized metals.

• EPDM and TPO rubber roofing — excellent adhesion and flexibility.
• Most PVC membranes and hypalon surfaces.
• Metal roofs, including coated metals like Kynar and copper when cleaned.
• Other materials: tile, wood, concrete, liners and even landfill or pond liners.

How do I apply the 4" x 20' tape for best results?

Application is straightforward: clean the surface, measure and cut the tape, peel the release liner, and press firmly to form a continuous seal. Smooth out air pockets and apply firm pressure to activate the adhesive for a reliable bond.

• Clean area of dirt, oils, and loose debris; use solvent if needed on metals.
• Cut tape to length, allow overlap at seams for extra protection.
• Remove liner and press down using a roller or hand pressure.
• Trim edges and inspect for bubbles; re-smooth any trapped air immediately.
