If you’re looking into getting your timber floors restored, you’ve probably come across both “floor sanding” and “floor polishing” — and wondered whether they’re the same thing or two different services. The short answer: they’re different processes that usually go together, but not always.
What Is Floor Sanding?
Floor sanding is the process of removing the existing finish and a thin layer of timber from your floor’s surface using industrial sanding equipment. The goal is to strip the floor back to clean, bare timber — removing old coatings, scratches, stains, and surface damage in the process.
Sanding requires professional-grade equipment — large drum or belt sanders for the main floor area, edge sanders for along walls and corners, and detail sanders for tight spots. After sanding, the bare timber needs to be coated with a protective finish.
What Is Floor Polishing?
Floor polishing refers to applying a protective coating to a timber floor — typically polyurethane, hard-wax oil, or another clear protective finish. Polishing can happen in two contexts:
- After sanding — as the final step of a full floor restoration, where the freshly sanded timber receives two to three coats of protective finish
- As a standalone recoat — where a new coat of finish is applied over an existing coating that’s still in reasonable condition, without fully sanding back to bare timber
A recoat involves lightly abrading the existing surface, cleaning thoroughly, and applying one or two coats of fresh finish. It’s faster, less expensive, and less disruptive than a full sand and polish.
When Do You Need Sanding vs Just Polishing?
You Need Full Sanding and Polishing When:
- The existing finish is worn through to bare timber in high-traffic areas
- The floor has deep scratches, gouges, or water stains in the timber
- You want to change the type of finish (e.g., from solvent-based to water-based polyurethane)
- You want to change the colour or stain of your floor
- The floor has old paint, carpet glue residue, or other surface contamination
- The existing finish is peeling, flaking, or has significant adhesion failure
A Polish Recoat May Be Enough When:
- The existing finish is dull or lightly scratched but not worn through to bare timber
- The floor still feels smooth and the finish is intact across most of the surface
- You want to freshen the appearance without the time and cost of a full sand
Cost Difference
A standalone recoat typically costs less than a full sand and polish because it involves less labour, less equipment, and fewer materials. However, a recoat only works if the existing finish is suitable to coat over. Applying new finish over a floor that really needs sanding is a false economy — the new coat won’t adhere properly and will fail prematurely.
Time and Disruption Difference
A full sand and polish typically takes two to three days for an average-sized home, plus drying time. A recoat is usually completed in one day, with shorter drying times. It’s less dusty and less disruptive overall.
Can All Timber Floors Be Sanded?
- Engineered timber floors — have a thin timber veneer over a plywood core. Depending on the veneer thickness, they can usually be sanded one to two times.
- Very thin or previously over-sanded floors — if the timber has been sanded many times before, there may not be enough material left for another sand.
- Laminate or vinyl plank flooring — not timber and cannot be sanded.
Frequently Asked Questions
Is “floor polishing” the same as “floor finishing”?
In Australia, yes — these terms are used interchangeably. Both refer to applying a protective coating (polyurethane, hard-wax oil, etc.) to a timber floor.
How do I know if my floor needs sanding or just a recoat?
Look at the high-traffic areas (hallways, in front of the kitchen sink). If you can see bare timber where the finish has worn through, you need sanding. If the finish is still intact but just looks dull, a recoat may be sufficient.
Can you polish a floor without sanding it first?
Yes — a maintenance recoat applies fresh finish over the existing coating after lightly abrading the surface. This only works if the existing finish is still in reasonable condition.
