Before You Sand Your Timber Floors: Recoat or Refinish?
When timber floors look dull, scratched or worn, a full sand may seem like the obvious solution—but it is not always necessary.
If the existing coating is still well bonded and the damage is mostly superficial, recoating may be enough to refresh the floor and restore protection without sanding back to bare timber. Full sanding is usually better for deeper scratches, failed coatings, exposed timber or a major colour change.
In this guide, we’ll explain when to recoat, when to sand, what affects the cost.
What Is Timber Floor Recoating?
Recoating is a maintenance option for timber floors that are still in generally good condition but have started to look dull, lightly scratched or worn.
Instead of sanding the floor back to bare timber, the existing coating is cleaned, prepared and lightly abraded before a fresh protective coat is applied. This can improve the appearance of the floor and restore protection with less time, dust and disruption than a full sanding process.
When Recoating May Be Enough
Recoating can be a good option when the timber is still in sound condition and the wear is mostly limited to the existing finish.
You may only need recoating if your floor has:
- Light surface scratches
- Dullness or loss of sheen
- Minor wear in traffic areas
- An existing coating that is still firmly bonded
- No exposed bare timber
- No major staining or deep damage
- No need for a significant colour change
When Full Sanding Is the Better Option
Full floor sanding is usually more appropriate when the damage has gone beyond the surface coating or the existing finish has started to fail.
You may need full sanding if your floor has:
- Deep scratches or gouges
- Worn-through coating
- Exposed bare timber
- Significant staining
- Peeling, flaking or failed finishes
- Uneven colour or heavy traffic wear
- A stain colour you want to change
- More substantial surface damage
Recoating vs Floor Sanding: What Does It Cost?
Cost is one of the biggest reasons to correctly identify whether a floor needs recoating or full sanding. Recoating is generally the less expensive option because the existing finish is retained and only prepared for a new protective coat, while full sanding requires the old coating to be removed and the timber refinished from a bare surface.
As a general Australian guide, professional floor sanding is commonly quoted from around $30–$60 per m², with the total price affected by the floor’s condition, timber type, preparation required and the coating system selected. Additional staining or premium finishes can increase the final cost.
The Right Choice Starts With the Condition of Your Floor
A dull or scratched timber floor does not automatically need full sanding—and it certainly does not always need replacing. If the existing coating is still sound, recoating may be enough. If the finish has failed or the timber itself is worn, full sanding and refinishing can restore the surface more completely.
The best option depends on the actual condition of the boards, how much wear is present and the result you want to achieve. Choosing the right approach can help reduce unnecessary cost, preserve more of the existing timber and avoid more disruption than the project really requires.
At Transform Floors, we assess the floor first and recommend the most practical solution for its condition. If you are unsure whether your floor needs recoating, sanding or full replacement, a professional inspection can give you a much clearer answer before you commit to the work.

Frequently Asked Questions
A simple visual clue is whether the scratch looks white, cloudy or superficial versus exposing a different colour beneath the finish. Fine marks that sit within the coating may be suitable for recoating, while scratches you can clearly feel with a fingernail or that expose bare timber are more likely to require sanding.
A professional assessment is still the safest approach because the depth of the scratch, coating type and previous refinishing history all affect what can be achieved.
The lifespan of either option depends heavily on traffic, pets, cleaning habits, furniture movement and the coating system used. Recoating is primarily a maintenance treatment designed to renew an existing finish before it wears through, while full sanding and refinishing resets the surface more completely.
Bona recommends inspecting timber floors regularly and recoating before the finish wears through to bare timber; with proper maintenance, this can significantly delay the need for another full sand.
Usually, yes, because recoating requires less preparation and does not involve removing the finish back to bare timber. Full sanding is more labour-intensive and may also require repairs, nail punching, staining or additional coating work.
Current Australian cost guides place professional timber floor sanding commonly around $30–$60 per m², with higher costs possible depending on floor condition and finish choice. Damaged or uneven floors generally cost more because of the additional preparation required.
There is no single number because it depends on the board thickness, timber type, previous sanding and how much usable timber remains above the tongue-and-groove joint. Solid timber can often be sanded multiple times over its life, while engineered timber is more limited because only the top wear layer is real timber.
This is one reason recoating can be valuable: if the finish is still suitable, renewing the coating preserves more of the timber instead of removing material unnecessarily.
Replacement may be the better long-term option when the floor has significant structural damage, extensive water-related deterioration, severe movement, widespread board failure or insufficient timber remaining for safe sanding.
In contrast, floors with cosmetic wear, scratches, dull coatings and moderate surface damage are often candidates for restoration. The key is to separate surface wear from structural failure before deciding.
At Transform Floors, the floor is assessed first so the recommendation is based on what the boards actually need rather than automatically pushing toward full replacement.
