The wear layer is the number that decides everything. Engineered hardwood may look like solid wood from above, but only the top veneer is sandable hardwood. Under that is the core. Sand through the veneer and the plank is finished in the bad way.
A homeowner may ask, “Can you refinish engineered hardwood?” The better question is, “How much wear layer do we have left?” That answer separates a safe refinishing project from a floor replacement quote.
Maryland homeowner note: engineered wood refinishing should start with inspection, not a sanding quote. USA Pro Floors checks the wear layer, finish condition, and safer recoat options before recommending full sanding.
Common wear layer ranges
- 1mm to 1.5mm: decorative veneer only; do not sand.
- 2mm: usually buff-and-coat only, not full sanding.
- 3mm: light sanding may be possible with an experienced crew.
- 4mm to 6mm: best engineered candidates for refinishing.
How pros inspect wear layer
- Check manufacturer specs when available.
- Look at vents, transitions, closets, or spare planks.
- Inspect bevel depth and previous sanding marks.
- Test inconspicuous areas before committing to aggressive sanding.
Why homeowners should care
- Wear layer determines cost, risk, final color options, and whether refinishing is worth it.
