The ability to refinish engineered hardwood depends on the thickness of its top hardwood layer. While solid wood can be sanded multiple times, engineered floors have a limited 'wear layer.' If the layer is too thin, sanding risks exposing the core material. Always confirm the wear layer thickness with the manufacturer before attempting to refinish. If suitable, professional sanding ensures a uniform finish without damaging the structural integrity, effectively extending the lifespan of your floor.
