## Key facts

- Oil finishes penetrate the timber for a natural, matt look; polyurethane forms a protective film on the surface.
- Oiled floors can usually be spot-repaired; polyurethane floors usually need a whole-area recoat to repair worn patches.
- Hardwax oil combines penetrating oils with waxes to give a slightly more protective surface than a pure oil.
- Under the NCC, stair treads need slip ratings of P3 (dry) or P4 (wet); the finish determines a timber floor's slip rating.
- Sanding and coating typically costs about $30–$70/m² installed (AUD incl. GST).

## The short answer

**Choose oil (or hardwax oil) for a natural, matt look that can be spot-repaired and refreshed without sanding; choose polyurethane for a harder-wearing surface film that needs less frequent maintenance but usually a whole-area recoat when it wears.** Both suit oak floorboards and parquet – the right choice depends on the look you want, how the room is used and how much maintenance you're happy to do.

## How each finish works

**Oil penetrates the timber and hardens within the wood fibres; polyurethane sits on top of the timber as a continuous clear film.**

- **Penetrating oil** – soaks in, leaving the surface feeling like timber. Protection comes from oil within the wood, refreshed with maintenance oil.
- **Hardwax oil** – a blend of oils and waxes. Penetrates like oil but leaves a thin, more protective layer at the surface.
- **Water-based polyurethane** – a clear film, available from matt to gloss. Stays close to the natural colour of oak. Some systems are two-part (2K) for higher durability.
- **Solvent-based polyurethane** – a tough film with a warm amber tone. Stronger odour during application.

## Oil vs polyurethane compared

**Polyurethane wins on day-to-day resistance; oil wins on look and repairability.**

| | Oil / hardwax oil | Polyurethane |
| --- | --- | --- |
| Look | Natural, matt, "unfinished" feel | Matt to gloss; more "coated" |
| Colour | Natural, white, tinted and smoked options | Clear; solvent-based adds amber |
| Scratch and spill resistance | Moderate | Higher |
| Local repairs | Usually possible – sand and re-oil the patch | Difficult – usually whole-area recoat |
| Routine maintenance | More frequent maintenance oil/products | Less frequent; screen and recoat when worn |
| Ageing | Develops patina | Wears in traffic lanes over time |
| Switching later | To polyurethane needs full sand | To oil needs full sand |

Exact performance varies by product – compare manufacturers' data sheets, not just finish types.

## Finishes and slip resistance

**The finish determines a timber floor's slip rating, so choose a tested product where a rating is required.** Under the NCC, stair treads need P3 (dry) or P4 (wet) slip ratings tested under AS 4586; level internal floors are not generally mandated ([SlipTest](https://sliptest.com.au/ncc-slip-resistance-requirements/)). Ask the finish maker for test results for the specific product and sheen. More in [slip resistance on timber stairs](https://timbo.com.au/guides/slip-resistance-timber-stairs).

## Which finish for which room?

**Match the finish to the room's traffic and the owner's tolerance for maintenance.**

| Room or situation | Common choice | Why |
| --- | --- | --- |
| Living, bedrooms, low traffic | Oil or hardwax oil | Natural look, easy refresh |
| Kitchens | Water-based polyurethane or well-maintained hardwax oil | Spill resistance vs easy repair – see [oak flooring in kitchens](https://timbo.com.au/guides/oak-flooring-kitchens) |
| Homes with dogs | Either – oil hides and repairs scratches; poly resists them | See [timber floors and pets](https://timbo.com.au/guides/timber-floors-and-pets) |
| Stairs | Product with the required slip rating | NCC requirement |
| Commercial, retail, hospitality | Durable polyurethane system or commercial-grade hardwax oil | Traffic and maintenance programme |
| Herringbone and chevron | Either | Oil accentuates the light/dark contrast of the pattern |

## Colour and sheen options

**Both finish types come in a range of colours and sheens – oil systems tend to offer more natural, tinted and smoked looks, while polyurethane offers more control over sheen.**

| Look | Oil / hardwax oil | Polyurethane |
| --- | --- | --- |
| Natural, "raw wood" | Natural or "invisible" oils | Ultra-matt water-based polys |
| White / Scandinavian | White-pigmented oils | Stain or tinted sealer under a clear coat |
| Smoked, grey or dark | Tinted oils, reactive stains | Stain under clear coat |
| Satin to gloss | Limited – oils are mostly matt to satin | Full range |

Always test the colour on a sample of the actual oak, sanded to the same final grit the floor will receive.

## Decision checklist

1. **Look** – do you want the timber to feel natural and matt, or protected under a clear film?
2. **Traffic** – kids, dogs, high heels, commercial footfall?
3. **Maintenance** – regular light upkeep (oil) or occasional bigger recoats (polyurethane)?
4. **Repairs** – how important is fixing a local scratch without redoing the room?
5. **Slip** – are there stairs or areas needing a rated finish?
6. **Programme** – how long can the room be out of use while coats cure?

## Cost

**Sanding and coating typically costs about $30–$70/m² installed in Australia (AUD incl. GST)** ([WhatsTheDamage](https://whatsthedamage.com.au/flooring-cost-brisbane/timber-floor-sanding-cost/)). Within that range, multi-coat 2K polyurethane systems and specialty coloured oils tend to sit higher. Over the life of the floor, oiled floors cost more in routine maintenance; polyurethane floors cost more per recoat.

## Raw parquet and finish choice

**If the parquet is supplied raw, you can choose any finish system on site; if it's prefinished, the factory finish sets your maintenance products.** Whether a Timbo batch is supplied raw or pre-finished: ask Timbo. For raw floors, see [sanding and finishing oak](https://timbo.com.au/guides/sanding-and-finishing-oak) for the process and [raw unfinished oak flooring](https://timbo.com.au/floorboards/raw-unfinished-oak-flooring) for the product type.

## Maintenance basics

- **Clean with the finish maker's recommended cleaner** – the wrong product can damage either finish.
- **Use felt pads** under furniture and mats at entries.
- **Avoid wet mopping**; use a well-wrung mop or a spray-and-wipe system.
- **Oil:** apply maintenance oil as the schedule recommends, focusing on high-traffic areas.
- **Polyurethane:** screen and recoat before wear reaches bare timber.

## Frequently asked questions

### Which is more durable, oil or polyurethane?

Polyurethane generally resists scratches, spills and wear for longer between maintenance, because it forms a tough surface film. Oil is less resistant day to day but easier to repair locally. Durability also depends on the specific product and how many coats are applied.

### Can you put polyurethane over an oiled floor?

Not directly. Oils and waxes stop polyurethane bonding. Changing from oil to polyurethane normally means a full sand back to clean bare timber; check with the finish manufacturer.

### Does polyurethane make oak look yellow?

Solvent-based polyurethanes tend to add a warm amber tone that deepens with age. Water-based polyurethanes are much clearer and stay closer to the natural oak colour. Ask for samples on the actual timber.

### Which finish is best for a kitchen with oak floors?

Many people choose a water-based polyurethane in kitchens for its spill resistance, but a well-maintained hardwax oil also works and is easier to spot-repair. Wipe spills quickly whichever you choose.

### Is an oiled floor more slippery than polyurethane?

Not necessarily. Slip resistance depends on the specific product and sheen. Where a rating is required, such as on stairs, choose a finish with test results that meet the required classification.

### Can I use furniture polish or wax on a polyurethane floor?

No. Polishes and waxes leave a film that makes floors slippery and stops a future recoat from bonding. Use only the cleaning and maintenance products the finish maker recommends.
