The short version
Keep grit off the floor, keep water off the floor, and use only products made for your floor's finish. Solid European oak is a durable, long-lived flooring timber, but the finish on top takes the daily wear. Most problems with oak floors – dull patches, scratches, grey water marks, gaps or cupping – come from grit, water, the wrong cleaner or big swings in humidity.
| Task | How often | How |
|---|---|---|
| Remove grit and dust | Daily or as needed | Soft broom, dust mop or vacuum with a hard-floor head |
| Damp clean | Weekly or as needed | Well-wrung microfibre mop, pH-neutral cleaner for the finish |
| Wipe up spills | Immediately | Dry cloth; don't leave water standing |
| Check felt pads | Every few months | Replace worn pads on chairs and furniture |
| Maintenance oil (oiled finishes) | When dull or dry | Compatible product, per the finish maker |
| Recoat (polyurethane) | When the coating shows wear | By a flooring professional |
| Full sand and refinish | Many years apart | By a flooring professional |
These intervals are general guidance – your installer's or finish manufacturer's instructions come first.
Everyday cleaning
Dry clean most days and damp clean only when needed, using as little water as possible. Fine sand and grit tracked in on shoes act like sandpaper and are the main cause of worn, dull finishes.
- Vacuum or sweep. Use a soft broom, a microfibre dust mop or a vacuum on its hard-floor setting. Avoid beater bars that can mark the surface.
- Damp mop. Use a microfibre mop wrung out until it is barely damp, with a pH-neutral cleaner made for timber floors and compatible with the finish.
- Dry as you go. The floor should dry within a minute or two. Puddles mean too much water.
Avoid: steam mops, bleach, ammonia, vinegar, methylated spirits, abrasive pads, wax or "shine" products not designed for your finish, and general-purpose floor cleaners. Some can soften the coating; others leave residue that makes later recoating difficult.
Oiled and hardwax-oiled floors
Oiled floors are maintained, not just cleaned: use a cleaner designed for oiled timber and apply a compatible maintenance oil when the surface looks dry or dull. Oil and hardwax-oil finishes soak into the oak and give a natural, low-sheen look. Their big advantage is that worn areas can usually be spot repaired without sanding the whole room.
- Use the soap or cleaner recommended by the oil manufacturer.
- Refresh high-traffic zones (entries, kitchens, hallways) more often than bedrooms.
- Don't put a polyurethane product over an oiled floor without professional advice.
Polyurethane floors
Polyurethane (and other film-forming) finishes are cleaned with a neutral cleaner and recoated by a professional before the film wears through to bare timber. A recoat – a light abrasion and new topcoat – is much quicker and cheaper than a full sand. Once the film wears through and the timber greys, a full sand is usually needed. The pros and cons are compared in oil vs polyurethane finishes.
Protecting the floor
Prevention is cheaper than repair. Simple steps make a big difference:
- Mats inside and outside external doors to catch grit and water.
- Felt pads on chair and table legs; replace them when they wear or collect grit.
- Lift, don't drag, furniture and appliances.
- Rugs in high-traffic areas, with backings that are safe for timber finishes.
- Footwear – stiletto heels and damaged shoes can dent any timber floor.
- Pets – keep nails trimmed and clean up accidents quickly. See timber floors and pets.
- Kitchens and wet areas – wipe spills fast and check for leaks under sinks and dishwashers. See oak flooring in kitchens.
Humidity, gaps and seasonal movement
Timber gains and loses moisture with the air, so a little seasonal movement is normal. The equilibrium moisture content (EMC) of timber is about 11% at 25°C and 60% relative humidity, but about 16% at 80% relative humidity (ATFA). Australian interiors typically sit between about 8% and 14% EMC (WoodSolutions).
In practice that means:
- Small gaps can appear in dry seasons or with heating, and close again in humid weather.
- Avoid extremes – long periods of heaters or air-conditioning running hard, or a house shut up and damp.
- If cupping, large gaps or lifting appear, call your installer early. The cause is usually moisture, and the sooner it's found the easier it is to fix. See moisture content in timber flooring.
Floors over underfloor heating need the heating run within the limits your installer gives you – see underfloor heating and oak flooring.
Sunlight and colour change
Oak changes colour with light exposure over time, and that is normal for a natural timber. The change is most noticeable in the first months. Move rugs and furniture now and then so the floor ages evenly, and consider blinds or window film for rooms with intense direct sun.
Repairs, recoating and sanding
Because Timbo's floors are 18mm solid oak, they can be sanded and refinished several times over their life – a key advantage over thin-veneer engineered floors, hybrids and laminates. Professional sanding and coating typically costs around $30–$70/m² in Australia (WhatsTheDamage), depending on the job.
| Problem | Likely fix |
|---|---|
| Dull traffic lanes | Maintenance oil (oiled) or recoat (polyurethane) |
| Light surface scratches | Spot repair or maintenance product |
| Deep scratches, dents, worn-through finish | Local or full sand and refinish |
| Grey or black water marks | Professional assessment; may need sanding |
| Gaps, cupping or lifting | Call your installer – usually moisture related |
For flooring businesses
Give every client written care instructions with the finish product name, and you'll prevent most callbacks. Partners can share this page or adapt it for their handover packs – it's part of Timbo's marketing support for partners.

Frequently asked questions
What is the best way to clean an oak floor?
Vacuum (hard-floor head) or sweep with a soft broom to remove grit, then wipe with a well-wrung microfibre mop and a pH-neutral cleaner recommended for your finish. Dry any wet patches straight away.
Can I use a steam mop on oak floorboards?
No. Steam forces heat and moisture into joints and the finish, which can cause swelling, cupping and finish failure. Most coating makers advise against steam cleaning.
How do I know what finish my floor has?
Ask your installer – they will know the product used. As a rough guide, polyurethane forms a visible film on top of the timber; oils and hardwax oils soak in and look more like bare wood.
How often does an oak floor need recoating?
It depends on traffic, pets and finish. Oiled floors get periodic maintenance oil when they look dry or dull; polyurethane floors are recoated when the coating shows wear, before it wears through to bare timber.
Will my oak floor change colour?
Yes, a little. Oak changes tone with light exposure over time, so areas under rugs can look different from exposed areas. Move rugs and furniture occasionally in the first year or two.
Can scratches in a solid oak floor be fixed?
Light scratches can often be blended with a maintenance product or local repair (easier on oiled finishes). Deeper damage can be sanded out, because 18mm solid oak has plenty of timber above the tongue.
What humidity is best for timber floors?
Stable conditions matter more than a single number. Avoid long periods of very dry or very humid air, which make timber shrink or swell. Your installer can advise for your climate.
