Next, you will need a carpentry toolkit, as it contains many useful tools that will make your task much easier, plus you can keep it in the RV during your travels, in case of unexpected incidents. Another item you should buy is replacement panels, as you won’t be fixing much if you don’t have them.

You will also be needing some epoxy wood hardener. Last but not least, you should consider buying or lending a sanding machine. If you can not afford one or do not believe it is needed, you can opt for sandpaper, though it will take quite a while longer to get the work done.

Step 4 – Start by Using The Epoxy Sealer Wood Hardener

Once you’ve cleared out the pipes and electric wires from the walls you are going to fix, you can then move on to using the epoxy sealer wood hardener. This part is meant for camper’s that have rotten or rotting wooden walls or wooden panels. The product usually contains a usage instructions guide book to help guide you throughout the process.

Step 5 – Removing unrepairable Walls

If the wooden walls or panels are beyond saving, then you might want to consider removing them and replacing them with a better alternative material, like thin styrofoam and luan. Luan is a soft plywood that can be stained or painted to fit your style. As it is a very thin material, it can be easily curved into the curved shapes of RV’s ceilings and walls.

Nevertheless, if you prefer to remain with the same wood style panels, you can buy new ones. Just pay attention to the materials and benefits of each panel before making your purchase.

Step 6 – Time to Use Your Sanding Machine

Once you have finished repairing all of the damaged walls, you can then move on to the next step. Grab the sanding machine or sandpaper and smooth the edges of each new panel or sealed panel. This is needed in order for them to match the surrounding walls that were not changed.
