Hardwood is a durable material, making both engineered and solid hardwood long-lasting options for your home. The individual layers of engineered wood are bonded together using extreme pressure, making it just as durable as solid hardwood. Plywood is slightly more flexible and less prone to warping under humid conditions, which makes engineered hardwood slightly more water-resistant than solid wood. On the other hand, the thinner top layer of engineered wood cannot be sanded down. If your engineered hardwood floors accumulate too much surface damage, you will have to replace them rather than refinish them. Solid hardwood can be refinished, which gives it a boost in longevity.
