One common issue RV owners face is delamination. This is also becoming more common as the yaers go by especially for new rv owners. In this blog post, we'll provide a comprehensive guide to fixing delamination on your RV.

What is Delamination?

Delamination is a process that occurs when the layers of an RV's fiberglass wall separate from each other. Some reasons for this may include: water damage, poor manufacturing, or just simply age. Delamination can cause bubbles, cracks, or soft spots on the exterior of your RV, and if left untreated, can lead to more serious structural issues. Therefore, it's essential to fix delamination as soon as you notice it.

Identifying Delamination

Before you can fix delamination on your RV, you need to be able to identify it.

Look out for these:

  • Visual cues: Look for bubbles, cracks, or soft spots on the exterior of your RV.
  • Tap test: Gently tap the exterior of your RV with a hard object. If you hear a hollow sound, it could indicate delamination.
  • Moisture meter: Use a moisture meter to check for any moisture inside the walls of your RV. High levels of moisture can cause delamination.

Tools and Materials Needed

To fix delamination on your RV, you'll need a few tools and materials:

  • Protective gear, such as gloves and goggles
  • Rotary tool
  • Fiberglass mat
  • Resin
  • Filler
  • Sanding equipment


Before you start repairing the delamination, you need to prepare the area. Follow these steps:

  • Clean the area thoroughly to remove any dirt or debris.
  • Remove any loose material or fiberglass using a rotary tool.
  • Sand the edges of the delaminated area to create a smooth surface.

Repairing the Delamination

Now it's time to repair the delamination. Follow these steps:

  • Apply resin to the delaminated area.
  • Cut a piece of fiberglass mat to size and place it over the resin.
  • Apply more resin over the fiberglass until it is fully saturated.
  • Use filler to smooth the area and let it dry.
  • Sand the repair until it is flush with the surrounding area.

Painting and Finishing

After you've repaired the delamination, it's time to paint and finish the area. Here's what you need to do:

  • Prime the area with a primer designed for fiberglass.
  • Paint the area to match the existing color.
  • Apply a clear coat to protect the area and give it a glossy finish.
