Painting the Interior Walls of Your RV

One of the most asked questions I get is how to paint interior walls on an RV. As most interiors come from the manufacture in stark white, it is only natural for one to want to personalize their RV and one of the best ways to do that is a coat of paint. That being said, you have to ask yourself if this will affect resale value, make the RV interior feel “smaller” or if you will tire of the color. All of these are valid questions that need to be addressed. Full timers with their RV of choice (i.e. their permanent “home”) are more inclined to tackle this project.

The biggest difference in painting your stick and brick home and painting your RV is, your S&B home walls aren’t covered with vinyl! Most manufacturers bond a vinyl sheet to luan board for the interior walls. While this product is easy to wipe clean, it presents a few more challenges to the painting project. The following suggestions have worked for me over the years, so I feel confident enough to pass on the do’s and don’ts.

Using the same techniques to paint hard surface laminates, like Formica, you can apply paint to a vinyl coated wall and have excellent results. While the following steps may seem time consuming, they are all relatively easy, because there is much less actual wall space to paint than in a S&B home.

The first step is to make sure the walls are clean of any grease or oils that may have accumulated over the years. The best product for this would be TSP. It will break down any type of oils and make for a clean palette. The most important part of using TSP though, is to make sure, after you have wiped down the walls with it, that you thoroughly rinse the wall with clean water. Failure to rinse the TSP off, could result the primer and paint coming off in “sheets”! If the walls are new or clean, you could skip the TSP step.

The second step is to “break” the gloss surface of the vinyl. Using a “fine” grade of sandpaper on a sanding block will do the job. Apply light pressure, being carefull not to actually sand down past the layer of vinyl into the luan!

The third step is to remove any dust from the sanding, using a “Tack” rag. These can be purchased in the paint department at the BBS (Big Box Stores) or at any hardware store.

The next step is one of the most time consuming, but the most important one for a professional looking end result: taping. Using blue painters tape (I haven’t tried the new green tape that is supposed to be better) carefully mask off the areas that won’t be painted. Many manufacturers use “gimp” the vinyl round beads that cover the seams at the corders and separate the wall from the ceiling. While it might be a pain in the tail, mask off the gimp at the wall-ceiling junction.

This will give a more professional result, and keep any stray paint off the ceiling if the paint “bleeds” through the tape. Also make sure to sand these gimps that are going to be painted, because paint doesn’t like to stick on them.

To give the paint something to really grip to, using an oil based primer is the next step. While it is tempting to use the latex version of “KILZ” or “BINZ”, everything I have read and have used specifies Oil Based primer. While it is harder to clean up after, the oil based primers are necessary for proper bonding. One note about these primers. Most stores will tint your primer so that it will be easier to cover with your final choice of paint color. The problem with this, is you may find yourself missing areas when applying your final paint, mistaking the primer for an area you have already painted. This wouldn’t be bad with a solid color as you can just go back over it when you catch the miss after it dries. But with any type of “faux” or ragging techniques, it can be a critical mistake. While most of these primers say that they dry within 30 minutes, let the primer cure at least overnight for a good bond.

Finally it is time to apply the paint. What color paint you use is strictly a personal choice. The rules apply in the RV just like in a traditional home. Dark colors will make the room look smaller. That’s probably one of the reasons manufacturers use white walls, lots of mirrors, and brass. Sorry, but that look just makes me think, motel room. But that’s just personal taste. The darker colors, make for a richer, homier look to your RV. IMHO

Another thing to consider is the finish of the paint. In our fulltimer rig, in the living room area, I used Ralph Lauren’s “Suede” paint. This is a faux finish, requiring a special roller and a two step process. While the end result was spectacular, a flat finish is not the most practical for RV use. If there is just the two of you, it would be fine, but pets and/or grandchildren have taken their toll in a couple of years, so I’ll need to be redoing it. An egg shell or semi gloss finish is more practical in an RV. I just finished the bedroom using a Ralph Lauren “antique leather” paint that I used before, and it has the egg-shell finish and is a more practical application as it can be damp rag cleaned. This is again a two step finish using “stipling” brushes. If any of these “faux” techniques appeal to you, buy a quart of the base and glaze and by a 2×2 piece of drywall to practice on. They have a real “wow” factor when finished.

Finally, when removing the tape, be mindful that while using latex paints are wonderful for cleaning, that word “latex” also means that the tape will have a tendancy to try to take some of your wall paint with it. I use a razor knife to carefully score the paint between the tape and the wall for easy removal. And while the paint may dry in just an hour or two, it won’t fully “cure” for a week or two. I realized this when I wanted to see how well the paint bonded to the vinyl the day after I painted. I ran my fingernail over the wall and was shocked to see the paint had come right off! After touching it back up, I left it alone for a week or two and had no more problems with adhesion.

For too many years, manufacturers have given us a wall paper border running throughout the RV and called it “style”. Maybe leaving the walls white is just an invitation for us to use our imagination. Good luck with your project!
