Assessing the Damage

Before we dive into the repairs, it’s essential to assess the damage. Take a close look at the affected area and determine the extent of the damage. Check for:

Dents and dings
Water stains and warping
Cracks and crevices
Delamination of the exterior finish

Once you’ve identified the problem areas, you can start planning your repair strategy.

Gathering Materials and Tools

To repair exterior RV walls, you’ll need the following materials and tools:

Fiberglass repair kit (for fiberglass RVs)
Body filler (for metal RVs)
Sandpaper (various grits)
Paint and primer (matching the original color)
Sealant (for gaps and cracks)
Rivets and screws (for reattaching loose exterior components)
Safety gear (gloves, mask, etc.)

Prep Work: Cleaning and Disassembly

Before you start repairing the exterior walls, you need to clean the area thoroughly. Use a mild detergent and water to remove any dirt, grime, or wax. This will ensure a strong bond between the old and new materials.

Next, disassemble any exterior components that may be in the way, such as trim, molding, and vents. Set them aside carefully to prevent damage or loss.

Disassembling Exterior Components

If you’re dealing with a particularly stubborn component, don’t be afraid to use a bit of force. However, be careful not to damage the surrounding area or strip any screws.

Repairing Dents and Dings

For fiberglass RVs, use a fiberglass repair kit to fix dents and dings. Follow the manufacturer’s instructions to mix and apply the resin. Allow it to dry completely before sanding it down to a smooth finish.

For metal RVs, use body filler to fill in dents and dings. Apply a thin layer of filler and let it dry before sanding it down. You may need to apply multiple layers to achieve a smooth finish.

Sanding and Smoothing

Use a variety of sandpaper grits to smooth out the repair area. Start with coarse grit (80-100) and work your way up to finer grit (220-240). This will help you achieve a smooth, even finish.

Repairing Water Stains and Warping

Water stains and warping can be a real challenge to repair. To repair exterior RV walls with water damage, you’ll need to address the underlying issue first. Check for any gaps or cracks in the exterior finish and seal them with a suitable sealant.

Next, use a molding and trim repair kit to fix any warped or damaged exterior components. Follow the manufacturer’s instructions to mix and apply the adhesive.

Painting and Finishing

Once you’ve completed the repairs, it’s time to paint and finish the exterior walls.

Painting

Use a high-quality exterior paint to match the original color. Apply a thin layer of primer first, followed by two coats of paint. Allow the paint to dry completely between coats.

Clear Coat

Apply a clear coat to protect the paint and give it a glossy finish. This will help to shield the exterior walls from the elements and extend their lifespan.

Reassembly and Final Touches

Once the paint is dry, reassemble any exterior components you removed earlier. Make sure they’re securely attached and won’t come loose while driving.

Final Inspection

Take a step back and admire your handiwork. Check the exterior walls for any imperfections or areas that need touch-ups. Make any necessary repairs before sealing the deal.
