How Can I Prevent Rot in My Camper Van’s Wood Flooring?

When working with wood in a vehicle, it's important to consider a few key points. Generally, using treated lumber for the subfloor is a good start, especially in moist areas. If your design allows, try cutting treated wood into narrow strips to create a gap underneath for drainage. You definitely want to avoid water sitting around because that leads to rot. Using moisture-rated plywood might be pricier, but it could save you in the long run. Also, don't forget to paint the underside with a heavy-duty exterior paint to create a moisture barrier; sealing those pores is crucial for preventing any wood decay. You could even add a layer of plastic for extra protection!

Consider where the rot is located. If it's near the entrance, you might want to add a weatherproof mat to catch some of the dirt and moisture before it gets to your flooring. I've heard that laying a subfloor with vinyl on top can really help protect against moisture too. It's a good way to keep things cleaner and drier over time!

If the wood is exposed to the elements and is already rotting, it sounds like it’s getting wet and staying that way. Try to identify where the moisture is coming from and rectify that first. You might want to check out pressure-treated plywood or marine-grade plywood, though they can be more expensive. Both options will withstand moisture better, but they won’t necessarily fix the root cause of the water issue. Getting to the source of the wetness is key.
