AOf course! Just like a traditional, solid hardwood floor, engineered hardwood can be re-sanded and refinished. This misconception comes from the misunderstanding that solid hardwood can be re-sanded right until the bottom of the product. A solid hardwood can only be sanded until just before the tongue and groove joint. This means that typically you will be able to get between 1 - 4 sandings out of a solid floor, and approximately 1 -3 out of an engineered hardwood floor. By the time a floor has become so worn that it would need a sanding, most people choose to rip it out and start from the beginning anyway.
