I painted the walls, it was super easy (unlike the cabinets) and it looks so much better. It looks less like an outdated travel trailer and more like a tiny house. Here is the before
Here it is now, with the walls painted as well (and I may have jumped the gun and added some of the rustic wood behind the TV. I love it and can’t wait to add the rest!)
If you have an RV that needs brightening up but you don’t want to spend forever working on it, paint the walls and leave the cabinets. Trust me on this.
Clean the walls – My recommendation for this would be TSP. It is a cleaner and degreaser made to use before painting, does an amazing job, and is dirt cheap. After cleaning, rinse the walls with water and let dry completely.
Prime the walls– If you want to use an oil-based primer, my favorite is Zinsser Cover Stain (Kilz is also a great choice). Oil-based works best (it’s the only thing that worked in the cabinets) but the clean up is a pain and it smells terrible, especially in a small space like an RV.
