Does Truck Bed Liner Work on Wood?

Truck bed liner is a great way to protect the inside of your truck bed. But, does it work on wood? The answer depends on what type of wood you are using.

If you are using treated lumber, like pressure-treated pine, then truck bed liner will work just fine. Pressure-treated pine is designed to be durable and water-resistant, so truck bed liner won’t damage it. It will help protect the wood from scratches and dents, and it may also help prevent moisture from seeping into the wood.

If you are using untreated wood, then truck bed liner may not be the best option. Untreated wood is more vulnerable to damage from chemicals and moisture, so applying truck bed liner could actually cause more harm than good. The chemicals in the liner could seep into the wood, causing it to rot or warp over time.

The best way to protect untreated wood is by applying a sealant or waterproofing product that is specifically designed for use on wood. These products will help keep moisture out while still allowing the wood to breathe. They can also provide some protection against scratches and dents.


In conclusion, truck bed liner can be an effective way to protect treated lumber from scratches and dents. However, it should not be used on untreated wood as it could cause more harm than good.
