What should I do with this bubble on my RV side wall?

You may have seen our series “What’s in the Shop?” Now, we’re sharing “What’s in the RV Group?” This is where we share posts and direct messages from Y-O-U. In this episode, Dustin shares how delamination occurs and most importantly how you can prevent it.

RV wall construction

I’ve seen many RV owners throughout my years in the industry try and heat the delaminated area and glue it back down. There is a reason why these jobs never look decent. Take a look at the below RV wall cut out. Your RV wall is made of the following:

  • Filon: Thin as a credit card
  • Luan: 1/8″ – 1/4″ thin
  • Styrofoam: 1″ – 1.25″

Unfortunately, there isn’t a quick fix for delamination repair. You are either paying a paint and body shop a large sum of money or you’re sealing the unit up to prevent further damage and living with this battle wound.

Preventing RV delamination

RV delamination can be prevented by ensuring your unit is properly sealed. Sealant and silicone are not permanent. I dare you to Google any RV owner’s manual. The typical owner’s manual will advise owners to inspect their exterior components at least every three months and to reseal immediately as needed.

Join the fun online! We have multiple Facebook groups where others share their problems, repairs, and upgrades. There are general groups, and groups tailored to your specific RV manufacturer. There is something there for everyone.

See if there is a manufacture warranty depending on who and when you bought it?

While I don’t have the delam issue, it is VERY beneficial to have the side wall construction information! I have wanted to mount a surge protector power strip in my AV cabinet to the upper edge of wall to create more space. I have been using velcro, but the heat of summer makes the velcro sag. Being able to attach screws will be a more permanent solution.
