4mm Wear Layer
Engineered hardwood flooring is a combination of low grade wood and a top layer of higher grade wood. First, the engineered floor is made up of three to 12 cross layers of plywood or low grade wood. Then, the top layer is placed on top and is made of the desired species of wood that will be seen. The top layer is known as the wear layer.
The wear layer of the 4mm engineered hardwood is the part of the floor that you will see and that makes direct contact with furniture and feet. The wear layer comes in different thicknesses and that will decide the lifespan of the floor. You can get a wear layer as thin as 1mm and as thick as 5mm. High end floors are most commonly found with a 4mm wear layer. The thicker the wear layer the more times you can sand and refinish the floor. The more times you can sand and refinish, the longer the floor will last. An engineered floor with a 4mm wear layer can be sanded and refinished around 3 to 4 times over the lifespan on the floor. This means the life expectancy of the floor is between 50 to 80 years, depending on how well you maintain the floor. How the process works is that you sand off a small portion of the wear layer to remove and scratches or dents. Then, a coat of finish is applied to keep the natural sheen of the wood.
When purchasing an engineered hardwood floor, it is important to choose a wear layer that is right for your needs. Thinner wear layers cannot be sanded and refinished, giving it a short lifespan. If you are looking for an engineered floor that will last a long time, a 4mm wear layer is your best choice. If maintained properly it will need to be sanded and refinished every 15 to 20 years and can have a lifespan up to 80 years.
