Two additional uses for Eternabond tape on your RV

Last month I shared reasons why I don’t recommend utilizing EternaBond tape on your RV roof (outside of using it as a patch). But today, I want to share two additional ways I do recommend using EternaBond tape on your RV.

Slide out roof

While I don’t recommend utilizing EternaBond® tape on the roof of the RV, I do recommend using it on the roof of your slide out. Specifically at the T-flange seam. In fact, RV manufacturers install EternaBond tape there as well—this wasn’t the case years ago.

EternaBond tape is a great option for this application because this water barrier provides a lower profile option compared to a sealant. It also allows the slide out seals to efficiently glide over the tape. Lastly, should you have your slide outs open and debris falls on the slide out roof, you won’t risk getting the debris stuck in the sealant.

Manufacturers typically install 4″ EternaBond tape strips in this location. Servicing your slide out and keeping the slide out roof clean and wiper seals conditioned is key to the longevity of your slide out function. Should the EternaBond tape on your slide out roof be past its prime, I recommend doing the following:

  • Thoroughly scrub your slide out roof and clean your existing EternaBond tape strip with a solvent cleaner. Let slide out roof dry.
  • Ensure T-flange is fully secured.
  • Remove any parts of the original EternaBond tape that is no longer sticking to the roof of the slide out or T-flange.
  • Install 6″-width tape over the existing EternaBond tape, ensuring the new tape goes up the T-flange by 1/4″ – 1/2″ and the remainder of the tape grabs the new slide out roof material.
  • Thoroughly press tape down and smooth out throughout the length of the slide out.

Please note: You will want to use 6″-wide EternaBond tape for this repair. It is offered in the following colors:

Moldings

All moldings (rain gutter molding, awning/slide out topper molding or a combination) are made in either 8-foot or 16-foot lengths. Depending on the length of your unit and how your manufacturer installed them, you will have at least one joint where two moldings are butted against each other. While the gap between the moldings appears insignificant, in my experience it’s just enough to let rain, morning condensation or condensation from an air conditioner to drip down the side of your RV. This drip is not only annoying but it can cause streaks.

Here is an easy way to prevent the drips:

  • Remove screws near the area where the moldings are butted against each other.
  • Clean the molding surface and let dry.
  • Peel and center a 3″ – 4″ length of tape over the joint of the two moldings.
  • Press the tape into the molding and smooth out.
  • Reinstall screws.

Please note: You will want to use 2″-wide EternaBond tape to do this repair. It is offered in the following colors:

Is this similar to flex tape?

Another use: I used the brown eternabond to cover those gaping holes around the water and drain lines that lead directly to the underbelly. I first stuffed the HUGE gaps with stainless scrubber pads then cut the tape to shape around the water lines and drains, removed the backing and applied to the cabinet bases. Hopefully this will keep those little field mice from getting into the interior living spaces.
