There’s a reason Australians keep coming back to timber: nothing beats the warmth, texture, and character of real wood underfoot. From the golden glow of Blackbutt to the rich drama of Jarrah and Spotted Gum, timber floors make a home feel… well, like home. But life happens. Grit, high heels, pet claws, prams, kitchen spills—after a few years, even the best floors start looking tired.
Here’s the good news: you usually don’t need to replace them. With the right timber floor restoration plan—and when it’s needed, professional timber floor sanding—you can restore timber floors to a “better-than-new” finish that lasts years.
In this comprehensive guide, we’ll walk you through:
Signs it’s time for timber floor sanding
Step-by-step restoration process
DIY vs professional approaches
Costs in Australia (2025 update)
Climate considerations (Sydney, Melbourne, Brisbane & beyond)
Maintenance tips to keep your restored floors looking stunning
By the end, you’ll know exactly how to get your timber floors shining again—and how to keep them that way for years to come.
The Short Answer
1. Do I need full sanding?
If your coating is worn through, you see grey wood, deep scratches, or water stains, yes—book timber floor sanding and refinishing.
2. Can I avoid sanding?
If damage is light (micro-scratches, dullness), a screen & recoat (light abrasion + new topcoat) often restores gloss without the mess.
3. How long will it last?
A professional timber floor restoration typically lasts 7–15 years with proper care and pH-neutral cleaning.
4. Cost (Australia, 2025):
- Screen & recoat: ~$18–$30/m²
- Sand & polish (clear): ~$30–$45/m²
- Stain or special finishes: +$10–$25/m²
- Board repairs/gap fill: +$5–$15/m² (repairs extra)
Why Choose Restoration Over Replacement?
Before we get into the “how,” let’s talk about the “why.” Replacing floors entirely can be costly and wasteful. Restoration offers huge benefits:
Cost savings – Restoring is typically half the price of replacing timber.
Sustainability – Reusing existing boards keeps waste out of landfill.
Preserves character – Many older Aussie homes feature hardwood species (like Brushbox or Tallowwood) that are rare or expensive to source today.
Adds property value – Freshly polished timber floors can boost your home’s appeal when selling.
Signs Your Timber Floors Need Restoration
How do you know it’s time to call in a floor sander—or hire one yourself? Look for these tell-tale signs:
Deep scratches and gouges that don’t buff out.
Grey or faded boards where the coating has worn away.
Water stains or warping, common in kitchens and laundries.
Splinters or rough patches that catch bare feet.
Sticky or cloudy residue from old wax or polish buildup.
If your floor looks tired, feels uneven, or simply doesn’t shine no matter how much you clean—it’s ready for timber floor sanding and polishing.
Know Your Floor First (Species, Construction, Coating)
Solid vs Engineered Timber
Solid timber: 14–19 mm thick, can usually be sanded 4–6 times over its life.
Engineered timber: Veneer thickness matters; ≥3 mm wear layer can handle 1–2 sands; thinner veneers are recoat-only.
Common Australian Species & What That Means
| Species | Density/Quirk | Restoration Tips |
|---|---|---|
| Blackbutt | Light, modern, can show tannin bleed | Water-based poly with sealer; manage humidity |
| Spotted Gum | Dense, movement-prone | More sanding passes; acclimatise well |
| Jarrah | Dark, very hard | Extra grit progression; test stains carefully |
| Tasmanian Oak | Softer, takes stain well | Gentle sanding; protect from dents |
| Brushbox | Silky grain, can be waxy | Degrease before coating; test adhesion |
Coating Type (Why It Matters)
Water-based polyurethane: Low odour, fast cure, non-yellowing; ideal for Sydney/Melbourne fluctuations.
Solvent/oil-based poly: Tough and glossy, warms the timber tone; longer cure, stronger smell.
Hardwax oil: Natural, repairable in patches; needs more frequent maintenance coats.
Old shellac/wax: Must be fully removed; can cause adhesion problems if not.
Restoration Pathways (From Light Touch to Full Rebuild)
Option 1: Deep Clean & Buff (No Recoat)
When: Light scuffs, haze, product residue.
How: pH-neutral timber cleaner + microfibre; never vinegar/steam.
Result: Fresher look; won’t fix finish wear.
Option 2: Screen & Recoat (The Hidden Hero)
When: Finish intact but dull or lightly scratched.
How: Light abrasion (“screening”) + new topcoat.
Pros: 1–2 days, minimal dust, budget-friendly.
Cons: Won’t remove deep scratches/stains.
Option 3: Full Timber Floor Sanding & Refinish
When: Bare wood showing, heavy scratches, stains, finish failure.
How: Progressive sanding grits → fill → stain (optional) → 2–3 coats of finish.
Pros: Resets the floor to “like new.”
Cons: More time, cost, and dust management.
Option 4: Localised Repairs/Board Replacement
When: Isolated water damage, pet stains, termite repairs.
Tip: Blend old/new colour with stain or tinted sealer, then coat entire room for uniform sheen.
Step-by-Step: Full Timber Floor Restoration (Pro-Level Overview)
1. Prep & Safety
Empty the space, remove skirting if replacing, punch down nail heads.
Seal doorways/vents, set up dust extraction, PPE on (respirator, ear/eye protection).
2. Sanding Grit Progression (Don’t Skip!)
Coarse cut (24–40 grit): Remove old finish, level ridges/cupping.
Medium (60–80): Erase coarse scratches, refine.
Fine (100–120): Smooth to coating-ready surface.
Edges & corners: Edge sander + hand scraping to match main field.
Stairs: Random-orbit sander + careful handwork; take your time.
Pro tip: Dense Aussie hardwoods (Spotted Gum, Jarrah) usually need slower feed rates and an extra pass per grit.
3. Gap Filling (If Needed)
Slurry fill: Fine sanding dust + binder; best for hairline gaps.
Resin/putty: Wider gaps or nail holes; tint to species.
Timber slivers: For historic homes with seasonal movement; most durable.
4. Dust Control & Tack
Vacuum meticulously (twice).
Tack cloth the surface just before coating. Any dust left will telegraph as nibs.
5. Stain or Tint (Optional)
Do full test patches (including a coat of sealer) before committing.
Wipe evenly with the grain; maintain a “wet edge” to avoid lap marks.
Neutralise/tannin-blockers where species require.
6. First Coat (Sealer/Base)
Choose a compatible sealer for your system (water-based, solvent, or oil/hardwax).
Follow manufacturer spread rates and conditions (temp, humidity, airflow).
7. De-Nib Between Coats
Lightly abrade with 150–220 grit screens or pads, vacuum/tack, then apply the next coat.
Typical systems: 3 coats for residential, 4+ for commercial or pets/kids.
8. Cure & Re-Occupy
Dust-free: ~2–4 hours (water-based) / longer (solvent).
Light foot traffic: ~24 hours (socks only).
Furniture: 3–7 days (use felt pads).
Rugs: 7–14 days (allow off-gassing and full cure).
Maintain ventilation; avoid wet mopping until fully cured.

DIY vs Professional Timber Floor Restoration
DIY Approach
Pros: Cheaper, rewarding if you’re hands-on.
Cons: Physically demanding, risk of uneven sanding, lots of dust.
Tools Needed: Drum sander, edge sander, orbital sander, vacuum, safety gear.
Cost: $500–$800 (equipment hire + products).
Professional Approach
Pros: Expert results, less stress, better finishes.
Cons: Higher upfront cost.
Cost in Australia (2025): $30–$40 per m² for sanding & polishing.
Extras: staining ($10–$20/m²), gap filling ($5–$10/m²), board replacement ($100–$150 per board).
For heritage homes or high-value hardwoods, professionals are worth every dollar.
Common Mistakes to Avoid
Even pros sometimes get caught out. Avoid these pitfalls:
Over-sanding: Thins boards, shortens lifespan.
Skipping grits: Leaves swirl marks.
Poor cleaning: Dust left on boards causes bumps in finish.
Wrong finish choice: Oil where water-based was needed.
Rushing cure time: Leads to peeling, bubbles, or imprints.
Troubleshooting After the Job
1. Cloudy Finish/Haze
Cause: Moisture trapped, incompatible products, or contamination.
Remedy: Allow full cure; if persistent, light abrade + recoat with compatible finish.
2. Tannin/Water Stains Reappearing
Cause: Reactive timbers (e.g., Blackbutt) or prior moisture events.
Remedy: Use tannin-blocking primer/sealer; moisture test before coating.
3. White Lines Between Boards
Cause: Cold coating bridging open joints (seasonal movement).
Remedy: Warm the space during coating; flexible finish; in severe cases, fill gaps.
4. Peel Lines Around Rugs
Cause: Plasticisers in rug backings or premature rug placement.
Remedy: Wait the full cure window; use breathable felt underlays.
How Long Does Restoration Last?
On average, a full timber floor sanding and polishing lasts 7–15 years depending on:
Foot traffic (pets, kids, shoes).
Quality of finish.
Climate conditions.
Maintenance habits.
Solid timber floors can be restored multiple times. Engineered timber (with thin veneers) can usually only be sanded once or twice.
Caring for Restored Timber Floors
Protect your investment with smart care:
Daily/weekly: Sweep or vacuum with a soft head to remove grit.
Monthly: Mop with a pH-neutral timber floor cleaner (avoid vinegar, bleach, ammonia).
Every 2–3 years: Apply a maintenance polish.
Every 7–10 years: Re-sand and reseal high-traffic zones.
Never use steam mops—they force moisture into the timber and cause cupping.
Australian Climate Considerations
Australia’s climate makes a big difference in timber performance:
Sydney & Melbourne: Fluctuating humidity → water-based polyurethane is safest.
Brisbane & Darwin: High humidity → engineered timber performs better than solid.
Perth & Adelaide: Dry heat → wax oils help maintain balance.
Tasmania: Damp and cold → oil-based finishes offer stronger protection.
Timber Floor Restoration Costs in 2025
Here’s what you can expect across Australia:
Sanding & Polishing: $30–$40/m²
Staining: +$10–$20/m²
Gap Filling: +$5–$10/m²
Board Replacement: $100–$150 per board
Example: A 50m² living room in Melbourne costs approx. $1,500–$2,500 for full sanding and polishing.
Timber Floor Restoration vs Replacement
When should you replace instead of restore?
Boards <12mm thick (can’t be sanded again).
Severe termite or water damage.
You want a completely new look (tiles, hybrid flooring, etc.).
But in most cases, restoration is more affordable, sustainable, and beautiful.
Wrap Up: Your Floors Can Look New Again
If your boards are looking a bit worse for wear, don’t hide them under rugs or replace them with something synthetic. A well-planned timber floor restoration—and when appropriate, professional timber floor sanding—will revive the natural beauty that made you fall in love with timber in the first place.
Start with a simple assessment: if you’re not at bare wood, a screen & recoat could buy you years of extra life. If the floor is genuinely worn, commit to a full sand and a modern, durable finish suited to your climate and lifestyle. Then protect your investment with smart, low-fuss maintenance.
