Can Engineered Hardwood Be Refinished?
Yes — engineered hardwood can be refinished if its wear layer (the top solid-wood veneer) is at least 2mm thick. A 3mm wear layer can typically be refinished 1–2 times; 4–6mm layers can handle 2–3 refinishes. Anything under 2mm is a screen-and-recoat only.
How to check wear-layer thickness
Pull a floor-vent grille or a threshold transition and measure the top layer above the plywood core. If you don't have documentation and can't see an exposed edge, we can measure during your consultation.
Screen-and-recoat as an alternative
If the wear layer is too thin to sand, a screen-and-recoat abrades the existing finish and applies a fresh top coat — no wood removed. Adds 3–5 years to any engineered floor.
Quick answers
- How can I tell if my floor is engineered or solid?
- Solid is one piece of wood; engineered has visible plywood layers when viewed from the side. Check a vent cutout.
- Does engineered refinishing cost the same as solid?
- Yes — the sanding is more delicate but pricing is comparable.
- What about click-lock engineered?
- Same rules apply — wear-layer thickness determines refinishability.
