For RV owners, water intrusion is one of the most common and frustrating maintenance issues. A small leak around a window, roof seam, trim piece, or exterior attachment may not seem serious at first, but over time, moisture can travel behind walls and create conditions that lead to delamination and dry rot.
The challenge is that much of this damage happens out of sight. By the time you notice bubbling fiberglass, soft spots, or changes in the exterior surface, the damage may have already been developing for some time.
Understanding what causes these problems and how to detect them early can help protect your RV and prevent more costly repairs.
What Causes RV Delamination?
RV delamination occurs when the layers that make up an RV wall, roof, or floor begin to separate. Most RVs are built using laminated panels that combine materials such as fiberglass, adhesives, insulation, and wood substrates.
When water enters through failed seals, cracks, or damaged exterior components, it can become trapped between these layers. Over time, moisture can weaken the bond between materials and damage the wood structure underneath.
Common areas to inspect include:
- Windows and doors
- Roof edges and seams
- Exterior trim and attachments
- Slide-out walls
- Storage compartments
- Entry steps and floor areas
How to Detect Dry Rot in Your RV
Dry rot often develops in areas that are difficult to see. Catching it early can help prevent a small repair from becoming a major restoration project.
Look for warning signs such as:
- Soft spots in walls, floors, or ceilings
- Bubbling or uneven fiberglass surfaces
- Water stains or discoloration
- Cracked or failing sealants
- Musty odors
- Loose interior panels or wallpaper
A simple tap test can also help identify problem areas. Solid areas typically produce a consistent sound, while areas affected by delamination or deterioration may sound hollow or different compared to the surrounding surface.
If an area feels soft or weak, further inspection may be needed. Damaged wood often loses its strength and may feel spongy or brittle.
Repairing Dry Rot with Git-Rot® Rx
Not every case of dry rot requires replacing large sections of your RV. When the surrounding structure is still intact, repairing the damaged wood fibers may be possible.
Git-Rot® Rx or Dry Rot Kit is a penetrating epoxy designed to restore strength to dry, weakened wood fibers. Unlike surface fillers, Git-Rot® penetrates the damaged wood and bonds with the remaining fibers to help restore structural integrity.
For the best results:
- Identify and correct the damage-causing source.
- Allow the wood to dry completely before application.
- Apply Git-Rot® so it can penetrate the damaged area.
- Allow proper curing time before finishing the repair.
It is important to remember that Git-Rot® is designed for dry rot repair, not wet wood. Proper preparation is essential for a long-lasting repair.
Protect Your RV Before Damage Gets Worse
Regular inspections of your roof seals, windows, doors, and exterior connections can help prevent serious water damage. Delamination and dry rot usually develop slowly, but finding the problem early can make a major difference.
With the right inspection and repair approach, Git-Rot® Rx for Dry Rot Kit can help restore damaged wood fibers and extend the life of your RV, keeping you ready for the adventures ahead.
