When Australians talk about "polishing" a timber floor, they mean the protective coating applied after sanding. It isn't wax buffing. The finish decides the colour and sheen of the floor, how it copes with boots, dogs and chair legs, how long the house is out of action while it dries, and how you'll look after it for years to come.
A note on search terms: "floor polishing" is also used for polished concrete and for strip-and-polish cleaning of vinyl and commercial floors. This page is about timber.
The main finish types
Water-based polyurethane
Water-based coatings are now widely used in homes. They have far less odour than solvent products, dry faster and stay closer to the natural colour of the timber, so pale boards stay pale. Two-pack versions, which are mixed with a hardener, are tougher than one-pack. They suit families who need to stay in the house or get back in quickly.
Solvent-based polyurethane
Solvent-based polyurethane builds a hard film and gives timber a warm, amber tone that deepens over time. Many people like that look on older floors. The trade-off is a strong smell while it goes on and dries, which usually means staying elsewhere for a few days, and longer drying in cold weather.
Penetrating oils and hardwax oils
Oils soak into the timber rather than sitting on top. They give a low-sheen, natural look, and worn spots can often be touched up without redoing the whole floor. They need more regular maintenance than polyurethane, especially in busy areas such as kitchens and entries.
Choosing a sheen
Most finishes come in matt, satin and gloss. Gloss shows scratches and dust more and looks more formal. Matt and satin hide everyday wear better and suit most homes. Satin or matt are often suggested for stairs, where a slick-looking surface isn't what you want.
Stains, tints and lime wash
Colour goes on after sanding and before the clear coats.
- Stains and tints can darken a floor, even out patched boards, or tone down the pink or yellow in some timbers. Results vary with species, so test patches are worthwhile.
- Lime wash and whitening give a pale, Scandinavian look. They work best on lighter timbers. A clear coat is still applied over the top, and some coatings can yellow over time, which shows on a pale floor. Ask about a non-yellowing system.
- Softwoods such as pine absorb stain unevenly and can go blotchy. Contractors often use a conditioner or a tinted coat instead of a heavy stain.
Cold weather and drying
Manufacturer drying and curing times are generally based on about 20 °C and moderate humidity. One widely used water-based finish lists light foot traffic after several hours and full cure after about three days under those conditions. Ballarat's winter mornings are much colder and more humid than that. In a cold house, expect:
- longer gaps between coats;
- a longer wait before you can walk on the floor or move furniture back;
- a recommendation to heat the house gently and keep it ventilated.
Some coatings shouldn't be applied below a minimum temperature. Your contractor should explain what the product needs and plan around it.
How long until you can use the floor
As a rule of thumb:
- Walk on it in socks: from several hours to a day or more, depending on the product and temperature.
- Light furniture: often after a few days, with felt pads on the legs.
- Rugs and heavy furniture: wait until the finish has fully cured, which can take a week or more for some products. Rugs laid too early can mark the coating.
Looking after a new finish
- Use felt pads under chairs and tables.
- Put mats at external doors to catch grit, which is especially useful in wet winters.
- Clean with a damp, not wet, mop and a cleaner suited to the finish.
- Avoid steam mops.
- Recoat before the finish wears through, which is cheaper than another full sand.
Questions to ask about a finish quote
- Which product, by name, and how many coats?
- Is it one-pack or two-pack?
- Will there be a sealer coat first, and is it compatible with any stain?
- What temperature does the product need, and will the house need heating?
- When can we walk on it, move furniture back and lay rugs?
- What cleaner should we use, and when should we plan the first recoat?
Clear answers to these make quotes much easier to compare.
What it costs
Finish choice affects the price. Australian 2026 guides put a sand with solvent-based polyurethane at roughly $30 to $45 per square metre, water-based at about $35 to $50, oils at $40 to $55 and stains or lime wash at $50 to $65. See prices for sources.
Frequently asked questions
What's the best finish for a family home?
There isn't one best finish. Many families choose a water-based polyurethane because it's low-odour, durable and quick to get back on. Solvent-based suits people who want an amber tone and can move out during the work. Oils suit people who are happy to do regular maintenance in exchange for a natural feel.
Does solvent-based polyurethane yellow?
Yes. It ambers over time, which can look warm on older boards but changes the colour of pale timber and lime-washed floors. Water-based products generally stay clearer.
Can I stain my floor a darker colour?
Usually. The floor needs to be sanded back to bare timber first. Dark stains show dust and scratches more, and some timbers take stain unevenly, so ask for a test patch.
How long should I stay off a newly polished floor in winter?
Longer than in summer. Cold slows drying and curing. Expect the contractor to give you times for foot traffic, furniture and rugs based on the product and the temperature in the house.
Can you polish timber floors without sanding?
You can apply a fresh coat over an existing finish that's still sound. That's a recoat. If the finish has worn through, a full sand is needed.
