RV Interior Wall Repair
The first common issue is interior wall damage. In order to repair it, follow these steps.
Case 1 Changing the paneling
- Tape off everything to cover what needs it to ensure that those covered areas be protected from the Rust-Oleum, liquid nail and expansion foam.
- Apply Rust-Oleum RV Leak Seal Rust inhibitor. Use two coats of it or as much as you think is needed. Let it dry overnight.
- Apply liquid nail, a synthetic rubber multi-use adhesive, which is solvent-based and with a non-runny consistency. It can deliver us with a lasting and consistent bond of most substrates.
- Get all the insulation back in its proper place before proceeding with the next step. Make sure that it is properly positioned as it was before.
- Apply the expansive foam to cement everything. Fill gaps and do it carefully.
- Cut all the excess foam. Let it set overnight. Use a little saw to make sure everything is flushed.
- For the paneling, use a big construction paper and cut it out to figure out the edges and corners especially for weird shapes.
- Lay the cutout on a panel board just as you can see in the photo above. Mark the shape and cut out using a jigsaw.
- Get the panel onto the wall and use a liquid nail to attach it.

- Cut out the paneling based on the measurements you have set it for, and do it right the first time to ensure you don’t have to repeat the process.
- Remove the insulation block using a flat bar just as what you can see in the photo.
- Check for any rust, and remove all that you can see. Get rid of the big flakes and smooth everything out as possible.
- Tape all the areas you never want to get paint on.
- Get a liquid nail and apply it generously. Take your insulation block and get it back into place.
- Check the gaps and use the expansive foam to fill them up. In the next day, you should remove the excess foam.
- Fit the paneling properly into place.
- Replace the plywood back into its position and screw it down at an appropriate depth to prevent screws hitting fiberglass etc. Screw with as many as you think necessary.
- Fill the entire gap and wipe it down. Use color putty for this application and cover the area well.

RV Fiberglass Wall Repair
To make small repairs on the fiberglass wall, prepare the things, including drill, breathing mask, eye protection, gloves, sandpaper, fiberglass repair kit, auto body filler, and foam insulation.
- Wear eye protection, gloves & a breathing mask. Remember that fiberglass can be stuck in your skin. It is also unhealthy to inhale.
- Using a sharp knife, you can cut away the damaged portion.
- Repair the insulation located behind the sliding if deep holed. Use expanding foam insulation on it and let it dry. Sand the excess foam insulation to level it with the rest of the insulation.
- Mix auto body filler, apply to the hole & let dry before sand flushing.
- Repair the fiberglass by applying it over the filler. Allow to drying before sand flushing.
- Paint the repaired area. Choose the correct color of the touch-up paint.
RV Foam Wall Repair
Another walling material to repair in your RV is the foam wall. Here is what you need to do.
- Get rid of the hole debris. Take all the drywall or plaster pieces clinging to the hole’s edges.
- Use some old newspaper to stuff into the hole. Be sure to arrange that at the bottom because it needs to support the spray foam later. Make sure that the area behind the hole is clear.
- Spray foam into the hole but only up to ¾ of the way because the foam will later expand to fill the hole.
- Allow the foam to harden. Usually, it will take up to two hours. After, you can cut flush it to the wall surface with a utility knife before shaping it to concave.
- With a drywall joint compound, use a layer of it to the hardened foam. Scrape the joint compound flat using the utility knife and then letting it dry overnight. Again, apply a coating before scraping to finish the task.
- Start sanding the final coat you have just applied when dried. To finish the job, prime the patch using PVA wall primer before painting it.
RV Laminate Wall Repair
Delamination is one of the major issues that have been plaguing many RV owners through the years. When this happens, there is usually water regression in the Luan, also called the interior panel & the film sheeting outside.
Due to the moisture buildup, the adhesive quality will be compromised, resulting to warping or bubbling found on the surfaces.
In some cases, it may be worth repairing but not in all. For the small cracks or punctures, you can repair them or take them to the auto-body repair shop or RV dealer.
With the aluminum siding, you can also find specific gel-coat-type waxes and cleaning products in order to keep the RV looking new.
RV Shower Wall Repair
Check out the following for tips on how to repair the RV shower wall.
- Turn the water supply off.
- Take the shower access panel out. If you cannot find the panel’s location, you should consult the RV manual.
- Locate and reach through the panel space. Disconnect both the cold and hot feeds, the pipes starting from the faucet assembly going to the showerhead, and the vacuum breaker.
- Remove fitted accessories. Remove shower walls. If your RV shower is not sectional, you can take the uppermost piece out first and then work all the way down towards the pan. In some cases, there may be brackets holding the panel to the enclosure. You can find them through the panel hole.
- Lift the shower pan, but avoid damaging the plumbing that carries the used water to the grey holding tank.
- Measure the exact size of the shower enclosure to buy a matching replacement.
- Read and follow the entire installation instructions that come with the replacement shower.

For water damage, expect a further challenge in the DIY task. Check out the following steps.
- Prepare a tape, 80-grit sandpaper, 60-grit sandpaper, epoxy resin or wood hardener, putty knife & wood putty.
- Look for water leak sources to prevent more water damage.
- If the leaks are entering through the windows, apply RV caulking.
- You can also patch up exterior siding and roof with waterproof tape. Apply it carefully because it will not come off once its backing sticks to the trailer.
- But for major exterior siding or roof repairs, you might want to ask help from a pro because it is labor-intensive.
- From the inside of the camper, look for all areas with water damage. Check the ceiling, floor & walls for signs as well as mushiness.
- You can also repair damaged wood in the wall by pulling off the loose pieces and smoothing the wood grit remaining using 80-grit sandpaper. Paint or spray-on epoxy resin or wood hardener. It will not just repair and harden the wood but will prevent mold growth, too.
- Apply wood putty after 24 hours in order to harden the wood. Use putty to fill the wood indents that resulted from the water damage. Dry the wood putty and sand it using 60-grit sandpaper to smooth it.
- Install the new paneling or wallpaper.
