RV delamination is a common and serious issue. When it occurs, it will affect the structural integrity of your rv. Delamination is a process where the fiberglass outer layer of an RV separates from the inner wall, causing the walls to become weak and less rigid.

This guide will help you understand what RV delamination is. Follow along to also find out how to identify it, and what you can do to prevent and repair it.

What is RV Delamination?

  • Definition: RV delamination is a process where the fiberglass outer layer of an RV separates from the inner wall, causing the walls to become weak and less rigid.
  • Causes: There are several factors that can contribute to RV delamination, including poor construction, water damage, extreme temperatures, and age. Poor construction can cause the layers of the RV to separate, while water damage can weaken the bond between the layers. Extreme temperatures can cause the materials to expand and contract, which can also weaken the bond.
  • Types: There are two types of RV delamination: sidewall delamination and roof delamination. Sidewall delamination occurs when the outer layer separates from the inner wall of the RV, while roof delamination occurs when the outer layer separates from the roof of the RV.

Signs of RV Delamination

  • Visual Indicators: The most obvious sign of RV delamination is the appearance of bubbles or ripples on the exterior of the RV. These bubbles or ripples are caused by the separation of the outer layer from the inner wall of the RV. You may also notice a soft or spongy feeling when you press on the affected area.
  • How to Check for Delamination: To check for delamination, you can use a soft mallet or your hand to tap on the walls and roof of your RV. If you hear a hollow sound, it could be a sign of delamination.

Prevention of RV Delamination

  • Maintenance Tips: Regular maintenance is the best way to prevent RV delamination. Make sure to inspect your RV regularly for signs of water damage and address any issues as soon as possible. You should also keep your RV clean and dry, and avoid exposing it to extreme temperatures.
  • Storage Tips: When storing your RV, make sure to park it on a level surface and use wheel chocks to prevent it from moving. You should also cover your RV to protect it from the elements.
  • Weather Considerations: Extreme temperatures and moisture can cause RV delamination. To prevent this, make sure to store your RV in a dry, climate-controlled environment. If you must park your RV outside, use a cover to protect it from the elements.

Repairing RV Delamination

  • DIY vs. Professional Repair: While DIY repairs are possible, it is best to have a professional handle the job. Delamination repair is a complex process that requires specialized equipment and knowledge. A professional can ensure that the repair is done correctly and that the structural integrity of your RV is not compromised.
  • Costs: The cost of delamination repair can vary depending on the how bad the damage is and the size of the area that is affected. On average, reapirs can anywhere from $500 to $5,000.
  • Steps Involved in Repair: Delamination repair typically involves removing the affected area and replacing it with new materials.
