The service life of SPC flooring mainly depends on the wear layer thickness, substrate quality, installation and daily maintenance. The residential version with 0.3mm wear layer can last 10–15 years under normal use. High-quality products with 0.5mm wear layer are suitable for families with pets and heavy foot traffic, with a service life of 15–25 years. High-density premium substrate can effectively reduce indentation and extend service time.

Thicker wear layers are required for commercial applications. Products with 0.5mm wear layer fit light commercial spaces such as offices and homestays, with a lifespan of around 10–15 years. The heavy-duty type with 0.7mm wear layer is designed for high-traffic areas including schools, hospitals and shopping malls, which can serve more than 15–20 years with proper maintenance.

SPC flooring cannot be sanded or refinished. Planks must be replaced once the wear layer is worn through. Several external factors may shorten its service life, including uneven subfloor, insufficient expansion gaps, long-term direct sunlight and continuous abrasion from sand and gravel. For foreign trade procurement, it is recommended to check third-party wear test reports to verify the claimed service life.
