Instructions: How to Paint an RV
Over the years, we have successfully renovated two travel trailers top to bottom and including the exteriors. To give both rigs a fresh new look, this is the exterior painting technique that we recommend.
Here is how to paint your RV’s exterior.
Wash your RV’s exterior
Wash your camper’s exterior to remove any dirt and road grime. Be sure to remove all decals from areas that you plan to paint. Never paint over decals. I recommend using a decal remover tool to remove any decals easily.
To remove RV decals:
Caulk all the exterior joints
After cleaning the RV’s exterior, make sure all the exterior joints don’t have any gaps or cracks in the caulk.
If there are cracks in the caulking, it’s important to reseal your RV exterior before you start painting.
Tape or mask off any areas
Just like painting the RV’s interior walls or your house, tape or mask off any areas that you do not want to be painted.
Use the masking paper to block off larger areas from the overspray.
After you’ve taped off the areas you want to paint, sand down all areas of the camper that you plan to paint.
Use an 80 grit sanding block and lightly buff the exterior to create a smooth surface. The purpose of this step is to create a roughened surface so the paint has something to adhere to.
Next, wipe down the RV’s exterior with acetone and a microfiber cloth to remove any oily residue that might prevent good adhesion.
Dust from sanding will ruin the paint texture. Wipe the area down again with a damp microfiber cloth to ensure there is no dust.
Using a paint sprayer, apply one coat of primer. The primer is an important step to allow for proper adhesion of the paint. Priming the exterior also helps unify the surface and allows for good paint coverage.
Remember: Never paint in direct sunlight or on windy days. Be careful not to stir up dust.
… peeling most often occurs when walls aren’t properly sanded or cleaned before being primed and painted.

Paint the 1st coat
A paint sprayer requires some finesse and technique. Here are some helpful tips for using a paint sprayer:
- Try to keep a wet edge
- Move in smooth, horizontal movements
- Keep your sprayer vertical
- Spray about 10-12 inches from your RV’s exterior
After allowing the paint to dry, lightly scuff the painted surface with a scuff pad.
Then wipe down the entire surface again with a clean damp cloth to remove any dust particles.
Apply the 2nd coat of paint
Apply another coat of paint to your RV’s exterior.
If the paint looks uneven after drying, scuff the surface once again and apply another coat of paint.
Depending on the condition that your RV’s exterior was in and how well you did in your preparation, you may need 2-3 coats of paint for a solid, smooth finish.
Now it’s time to enjoy that beautiful exterior. Remove all painter’s tape and masking paper.
Once the paint has fully cured according to the Dupli-Color instructions (or whatever RV exterior paint you chose), buff the surface to enhance the paint’s look.
How to Protect Your RV’s Exterior from Damaging UV Light
Now that your RV’s exterior is cleaned up and freshly painted you’re going to want that finish to last. The sun’s harmful UV rays can make quick work damaging the finish on your motorhome or trailer. Over time, sun exposure can make your RV decals fade and can dull the finish.
Here are some simple ways to keep your RV’s exterior looking like new:
- Wax your RV regularly
- Park in the shade when possible
- Store your RV properly in the winter or invest in a high-quality RV cover
