Eternabond RoofSeal is a trusted solution for RV roof repairs—but like any product, it must be applied correctly to work effectively. Here’s a step-by-step guide to ensure strong adhesion and long-lasting results.
The most important step is cleaning. The roof surface must be clean and dry before applying the tape. Remove dust, oils, and contaminants using rags with rubbing alcohol or other recommended cleaners.
If the roof is dusty, wipe it with a damp cloth first and let it dry completely. Moisture or debris will prevent proper adhesion.
Measure the area that needs repair and cut a piece of tape slightly longer than needed. Rounding off the corners helps prevent peeling over time.
Use shorter sections for small patches—they’re easier to handle.
Peel back a few inches of the release liner from the adhesive side. Avoid touching the adhesive or letting it stick to unintended surfaces.
Hold the liner tab so you can easily continue removing it as you apply the tape.
Starting at one end, press the tape down firmly while slowly peeling away the liner.
Apply strong, even pressure using your hand or a seam roller. This helps eliminate air pockets and ensures a tight bond.
Go over the tape several times to activate and fully bond the adhesive.
After applying the tape, press down around all the edges and ends. This final step ensures the tape is sealed completely.
When working around corners or uneven surfaces, it's essential not to overstretch the tape. EternaBond should be laid in gently and pressed into place without pulling.
Stretched tape can pull away from the surface over time, causing gaps and potential leaks. Always press the tape fully into the corner and bring it all the way down to the edge to avoid uneven joints.
Use a roller for consistent pressure and to ensure complete contact along every edge and angle.
Improper application—such as using tape on a dirty surface, not pressing it tightly, or allowing wrinkles—can actually create voids that funnel water into your RV instead of sealing it out.
Inspection Quick Check:
For repairs involving roof T-molding and membrane seams, Eternabond-type tapes should run the full length of the roof edge to function as a proper secondary seal.
Eternabond RoofSeal stretches and flexes with your RV as it drives, so it won’t crack or lift over time. It adheres to:
It’s ideal for sealing around skylights, vents, antennas, and patching punctures or seam separations—even in remote locations.
Pro tip: Keep a roll in your camper for emergency use. When applied correctly, it can hold strong through heat, cold, road vibration, and UV exposure.
Whether you're on the road or at a campsite, a properly applied strip of RoofSeal can be the difference between a minor fix and a major leak.
