Wear layer
The thickness of real hardwood above the core — what determines how many times a floor can be refinished.
On solid hardwood the wear layer is generational. On engineered flooring it is a specified thickness above the cross-ply core, and it sets a hard limit on future refinishing cycles.
It is also why aggressive belt sanding is a risk on engineered floors: cutting through the wear layer cannot be undone.

Terms this one depends on
- Engineered hardwoodFlooring that pairs a real hardwood wear layer with a 90° cross-ply core, which is what gives it dimensional stability over concrete, in condominiums and above radiant heat.
- Solid hardwoodFlooring milled from a single piece of wood, typically 3/4" (19 mm), with a generational wear layer and high sensitivity to humidity swings.
- Planetary sanderA refining machine with three or more counter-rotating discs on a rotating head, producing a random multi-directional scratch pattern that blends field into edges.
- Belt floor sanderThe primary material-removal machine in a refinish: a continuous abrasive belt over a drum roughly 200 mm wide, handling around 80% of total removal.
