What You Need to Know About RV Delamination

Whether you’re just starting your RV journey or have logged thousands of miles on the road, chances are you’ve come across the term delamination. It’s a word that can raise concern, and for good reason. Simply put, delamination refers to the separation of layers within the RV’s walls, roof, or flooring. And while it might start small, it can turn into a big deal if not addressed.

Why Does Delamination Happen?

In most cases, water is the main culprit behind delamination. Moisture intrusion—often through cracked sealant, worn window caulking, roof leaks, or damaged trim—sneaks into the RV’s structure. Once water finds its way in, it can break down the adhesive that holds key layers together, such as plywood, fiberglass, and foam insulation. Over time, these layers begin to pull apart.

The result? Those familiar bubbles or ripples on your RV’s exterior that not only look unsightly but signal a bigger problem brewing underneath.

Older RVs are especially prone to delamination, but newer models aren’t entirely safe either. Poor maintenance, exposure to harsh climates, and using the wrong sealants can all increase the risk. And while early signs might seem purely cosmetic, left unchecked, delamination can compromise the RV’s structural integrity.

Can You Repair Delamination Yourself?

This is a question many RVers ask and the answer is: it depends. For minor separation, you might be able to tackle the job yourself with a delamination repair kit. These typically include syringes and tubing that let you re-bond the separated layers without tearing everything apart.

But if the damage is extensive, a simple DIY solution may not cut it. In more serious cases, the affected area may need to be stripped down and rebuilt with fresh materials. That’s a bigger job that requires time, tools, and a good understanding of your RV’s construction.

If you’re not confident taking on a project of that scale, calling in a professional is often the smart move.
