Slide-out roof EternaBond tape failure… and fix

By Dustin Simpson
Follow me at my shop, California RV Specialists, during an inspection of a 2019 Winnebago Minnie Plus. I’ll find the cause of water leaking into the interior of the unit with the slide-out in the out position during rain.

While inspecting the unit, I discovered that the 2-inch EternaBond tape was coming loose around the screws and making small channels that were allowing water to get past the slide-out flange and leak through the fascia.

I also discovered multiple areas on the slide-out flanges and fixtures where sealants had separated, putty was bleeding out, there were voids and gaps, and aged sealant had come loose.

Dustin’s recommended steps:

• Clean up old EternaBond surfaces with a low-grade body solvent.
• Remove any loose tape or areas of concern.
• Apply 4-inch EternaBond tape over the original, splitting the difference between the flange surface and going beyond the old EternaBond tape surface.

Watch the whole process in these two videos below:

Here is a link for Quick Roof Extreme White 4″ x 25′ for slide-out roof seams. The tapes are available in white or black, and they come in 4” – 6” widths and 12.5 ft., 25 ft., and 50 ft. lengths.

Also there is 2″-wide EternaBond tape to do this repair. It is offered in the following colors:

• White
• Black

And here is a link for slide-out rubber seal conditioner treatment. I like this one because it comes as a hand spray bottle so it can be used inside on the slide-out seals and you can control it better.
