Well that depends on what kind of finish the wood floors have. Softwoods like pine, cedar and redwood are more non-porous than other woods, making them great choices for hardwood flooring materials. In addition to softwoods’ non-porous nature, when applied as floors they are almost always treated or coated with some sort of finish to keep moisture out and increase their lifespan.
Hardwood floors can either be sealed on the surface or treated. A surface seal does just what it sounds like. It sits on top of the wood and helps prevent water and other stains from being absorbed into the wood. Most hardwood floors are finished this way because it makes them easier to clean and maintain. Alternatively, hardwood floors can also be finished with an oil that penetrates and is absorbed into the wood. This finish mimics the look of bare wood for a more natural effect, but in doing so, also leaves the wood more porous and vulnerable to water and other stains.
Overall, wood floors are more porous than alternative flooring options like luxury vinyl and laminate, but with the right finish and upkeep, they can hold off damage from water or air for decades. Because hardwood floors range in how porous they are, it is always smart to consult a flooring expert and to examine your warranty to learn about the proper maintenance for your floors.
