An engineered floor with a 3mm wear layer can be sanded and refinished approximately 2 to 3 times over the lifetime of the floor. *Approximate lifespan 40-50 years. An engineered floor with a 4mm wear layer or thicker can be sanded and refinished approximately 3 to 5 times over the lifetime of the floor. *Approximate lifespan 50-100 years or more. *Lifespan depends on the quality of maintenance and the number of times the floor is sanded and refinished.
