Flooring glossary
Plain-language flooring terms with source boundaries.
A homeowner glossary that explains terms, distinguishes commonly confused concepts, and points to deeper resources without turning definitions into sales copy.
Direct answer
A useful flooring glossary gives the plain meaning, why it matters, what it is not, and a source. It does not turn a technical term into a promise about a specific floor or PHR service.
Start with the floor
Good decisions begin with what you can see.
This PHR-supplied floor photo is here to give the guide a real wood reference. It does not diagnose your floor or promise the same look. The details below help you ask better questions about your own home.
Terms that are often confused
Solid and engineered hardwood both use real wood, but their construction differs. A vapor retarder, moisture barrier, and moisture-mitigation system are not interchangeable labels. Dry time and cure time describe different stages.
- Janka is comparative indentation data—not a scratch-proof rating.
- A screen & recoat is not the same as complete sanding to bare wood.
- Cupping and crowning are different board-shape symptoms and should not be diagnosed from a single photograph.
How this glossary stays useful to people and answer engines
Every future term page will put the definition near the H1, name a source and review date, distinguish related terms, and link to one verified deeper resource. Incomplete terms remain blocked rather than filled with plausible sales copy.
