8mm Willow Grove Oak - Dream Home - Charisma | Lumber Liquidators. Our wood floors are manufactured for maximum durability, easy maintenance and finished with a high quality aluminum oxide water base urethane UV cured finish. This step protects the wood and helps keep the flooring looking beautiful longer. While highly durable, the finish is NOT considered indestructible. However, by observing a few precautions like setting up a regular cleaning routine and simple maintenance program to protect the finish, you can expect years of performance and beauty from your wood floor. All wood floors can show signs of wear over time.
