An Understanding of RV Delamination for Beginners

RV Delamination

When one starts noticing blisters, bubbles, and wave-like formations on the sides of an RV’s walls, it is a matter of concern. These are all signs of RV delamination, and it is not a good thing to happen to a vehicle. Though it is the most common issue, one must thoroughly check for RV delamination when buying a second-hand vehicle. Furthermore, it is vital to address the signs of RV delamination immediately to avoid problems aggravating in the future and resulting in expensive repairs.

What is RV Delamination?

When the gel coat layer, fiberglass, or lamination coating on the exterior of an RV starts to bubble and tear away with blisters and waves, it is known as RV delamination. It is this coating that safeguards a recreational vehicle from external elements. Over time, the protective layer undergoes wear and tear, which must be fixed as soon as it is noticed.

Identifying an RV Delamination

In most cases, an RV delamination can be noticed immediately. It appears cosmetically on the exterior part of a recreational vehicle. One can notice bubbles and blisters on the exterior paint job of the vehicle. Additionally, RV delamination is also visible, like a sagged-down canvas off the walls.

People often complain of RV delamination as a wavy exterior plastic covering that might be soft or squishy to the touch. This is a severe sign that indicates the trapping of moisture beneath the coating and demands immediate attention. The good thing is that RV delamination is easily visible and noticeable to individuals. Hence, addressing the issue is also faster.

How Does Delamination Impact an RV?

The worst part about delamination is that the exterior covering of the RV gets peeled away. This allows the trapping of moisture between an RV’s exterior and interior side walls. The walls are usually wood, plastic, or other metal frames. Letting the moisture get trapped can lead to disastrous circumstances.

 The formation of mold seems to be the biggest problem concerning RV delamination. Mold is the breeding ground for allergies and several other medical issues. Furthermore, the trapping of moisture can also affect the frame and exterior fiberglass of the RV. Hence, the overall structure of the RV gets impacted, making the vehicle unsteady.

Fixing Costs of an RV Delamination

The longer one waits to address the issues and fix them, the more expensive it is to repair RV delamination. Sometimes, moisture and mold formation don’t just affect the exterior walls of an RV but the interior components as well. Hence, one might have to replace every element, like wooden and metal frames, furniture, cloth, etc. The cost of fixing and replacing interior furnishings can go up to $1500 and sometimes even more. One can also find a DIY RV delamination repair kit, which costs around $300 to $400.


The instances of RV delamination can be prevented or eliminated when regular yearly maintenance checks are undertaken. Furthermore, it is suggested that any openings, cracks, or potential dents on the exterior of an RV shouldn’t be ignored. Addressing the issues can prevent delamination.
