July 1, 2024

Owning an RV is a wonderful way to explore the great outdoors with the comforts of home. However, RVs are subject to various forms of wear and tear, and one of the most common issues is delamination. Understanding how to repair RV roof leaks and deal with delamination is essential to maintaining your RV’s structural integrity and aesthetic appeal. In this comprehensive guide, we’ll walk you through the step-by-step process of repairing RV delamination.

Step-by-Step Guide to Repairing RV Delamination

What is RV Delamination? RV delamination occurs when the outer fiberglass layer separates from the underlying plywood or luan board, often due to water infiltration. This can cause bubbling or warping on the RV's exterior and, if left untreated, can lead to significant structural damage. Here are the steps of repairing RV delamination.

1. Identify the Extent of Delamination


Carefully inspect the exterior of your RV for signs of wear such as bubbles, scratches, or soft spots.

Tap Test

Tap the RV walls and roof with a coin or your knuckles. A hollow sound indicates separation.

2. Prepare the Area

Safety first

Be sure to wear protective gear, including gloves and eye protection.

Clean the area

Wash the affected area with mild detergent and water to remove dirt and debris.

Dry the Area

Allow the area to dry completely to prevent further moisture issues.

3. Remove Damaged Material

Cut Away Delaminated Section

Use a utility knife or rotary tool to cut away the delaminated section of fiberglass.

Remove Wet Insulation

If there is any wet insulation or wood, remove it and allow the area to dry thoroughly.

4. Repair the Substrate

Replace plywood or luan

Replace any damaged plywood or luan board with new material.

Apply adhesive

Use a high-quality adhesive designed for RV repair to attach the new plywood to the existing structure.

5. Reattach the Fiberglass

Apply Epoxy

Mix and apply epoxy resin to the backside of the fiberglass panel.

Press and Clamp

Press the fiberglass back into place and use clamps to hold it securely while the epoxy cures.

6. Seal and Finish

Seal the edges

Apply a waterproof sealant around the edges of the repair to prevent future water leakage.

Sand and paint

Sand the repair area roughly and apply matching paint to blend the repair with the rest of the RV.
