Design Timber Flooring sands and finishes timber floors across Greater Sydney. Jimmy has spent more than 20 years on Sydney floors, and he quotes and runs every job himself. Before any machine goes down, an assessment establishes whether the existing floor is suitable for a recoat, a full sand or repairs before finishing. The least invasive suitable option depends on the boards, the remaining usable timber and the existing coating.
Whether you have tired boards in a Federation cottage, floorboards under carpet or a newer floor that has lost its sheen, this page explains what floor sanding and polishing in Sydney involves and how to plan around it.
Signs your floor needs attention
Not every dull floor needs a full sand. Look at the surface in good light:
- Grey, worn tracks through hallways and kitchens.
- Scratches in the coating only, compared with dents and gouges in the timber.
- Finish worn through, with bare timber darkening or absorbing spills.
- Old finishes that have yellowed, peeled or flaked.
- Cupped or uneven boards, stains, or paint and adhesive from past renovations.
Some are finish problems, some are timber problems and some point to a cause that needs resolving first. The assessment tells them apart.
Recoat or full sanding?
A recoat may suit some floors with surface wear where the existing finish is compatible and the timber is sound. Deeper wear, stains or an uneven surface may need a different approach. Sanding does not resolve every stain, moisture problem or movement issue, and some boards do not have enough usable timber for another sand.
| Consideration | Floor recoating | Full sand and polish |
|---|---|---|
| Suits | Sound finish with light surface wear | Worn-through finish, deeper scratches, uneven or stained boards |
| What happens | Existing coating is cleaned, abraded and a fresh coat applied | Old coating is removed and the timber is sanded back before new coats |
| Timber removed | Very little, the coating does the work | Some of the board surface, which matters on older or previously sanded floors |
| Colour change | Keeps the current colour | Opens the option of a new stain or finish |
| Key check | Compatibility of the new coat with the existing finish | Remaining usable timber, fixings and board condition |
A recoat is a different job for a different floor, not a cut-down full sand. If the existing finish is failing, a recoat over it will not hold.
If damaged hardwood needs attention first, our board repair service can assess it. We discuss the floor's condition before recommending the finishing scope.
Sanding floorboards under carpet
Many Sydney homes, from inter-war bungalows to post-war brick houses, have original hardwood under the carpet. Lifting a corner is a good first look, but gripper strips, staples, underlay residue, paint lines and patched sections are common once the carpet is up.
Before booking floorboard restoration, we check for replaced boards of a different species, particleboard sections, termite or water damage and the height of the fixings. Some can be repaired and blended; others change the recommendation. Our carpet-to-timber guide covers the decisions to make if you are still weighing up new flooring against restoring what is there.
Dust-controlled preparation
We use vacuum-assisted sanding equipment to reduce dust at the source. No sanding process is completely dust-free. Preparation includes checking the surface, addressing agreed board repairs and protecting the work area. The sanding sequence is selected for the floor and finish rather than applied as a fixed recipe.
The sanding process, step by step
- Assessment and scope. Inspect the boards, coating, fixings and damage, and agree on the finish and rooms.
- Preparation. Protect doorways and adjoining areas, and punch or remove exposed nails and staples.
- Repairs. Complete agreed board replacements so the whole floor is sanded together.
- Initial sanding. Remove the old coating and level the surface.
- Edges and corners. Edging machines and hand tools reach the perimeter and around fixed joinery.
- Gap filling. Fill suitable gaps and nail holes before the finer passes.
- Finer sanding. Progressively finer grits refine the surface.
- Colour and coats. Apply any stain, then the sealer and finish coats, cutting back between coats where the system calls for it.
- Handover. Walk through the floor and provide care and return-to-use instructions.
The number of passes and coats depends on the floor, the product and the result you want. For stair sanding, see our timber stairs service if your staircase is part of the project.
Gap filling
Gaps between boards are normal. Timber moves with Sydney's humidity, so gaps can open in drier months and close when it is humid. Fine gaps and nail holes are usually filled with filler mixed with the floor's own sanding dust, so the colour sits close to the timber.
Filler in a wide gap that keeps moving can crack or drop out. Options include filling selectively, leaving some gaps as character or addressing the cause. We discuss what is realistic rather than promising a gap-free floor.
Staining and colour options
Many people let the natural colour of Blackbutt, Spotted Gum, Brushbox or Sydney Blue Gum speak for itself under a clear finish. For a different look:
- Natural. A clear coat that deepens the timber's own colour; some finishes add more warmth than others.
- Whitewash or limed. A pale, softened look. On red-toned species it can read pink or muddy.
- Darker tones. Striking, but dust, scratches and pet hair show more readily.
Species, age and how the timber takes up stain all affect the result, and a colour chip is only a guide. We recommend a test patch on your own floor, in your own light, before committing. Floors with mixed or replaced boards can take colour unevenly.
Choosing a finish: polyurethane vs hard wax oil
We work with water-based polyurethane and hard-wax oil finishes. Compare the desired sheen, maintenance requirements and suitability for the selected timber. Product specifications govern drying, curing, care and any future touch-up process. A finish should be chosen for how the room is used as well as its appearance.
Many older Sydney floors already carry an oil-modified or solvent-borne coating, so it is included below for comparison because it affects what can go over the top.
| Finish type | Look and feel | Strengths | Trade-offs |
|---|---|---|---|
| Water-based polyurethane | Clear, stays closer to the natural timber colour, available in matt through to gloss | Hard-wearing surface film, lower odour than solvent-borne coatings | Scratches sit in the film; worn areas usually need a recoat of the whole room rather than a spot repair |
| Oil-modified or solvent-borne polyurethane | Warmer, more amber tone that can deepen over time | Durable film, familiar on many older floors | Stronger odour during application and curing; tends to yellow with age |
| Hard-wax oil | Soft, low-sheen, natural feel that penetrates the timber | Worn or scratched areas can often be maintained locally | Needs more regular maintenance with the right products; less resistant to standing spills |
There is no single best finish; a busy kitchen and a formal living room suit different trade-offs. If you have dogs, our guide to timber flooring with dogs explains what to think about when choosing sheen and finish.
Preparing your home
- Clear furniture, rugs and anything stored on the floor, including inside wardrobes in the scope.
- Tell us about pets, alarm sensors and anyone sensitive to odour.
- Plan for kitchens, bathrooms and exits that are unavailable while coats dry.
- Take down curtains that touch the floor.
Living arrangements during the work
The programme depends on floor condition, area, preparation, coating system and site conditions. Agree on which rooms can remain accessible and whether staying in the home is practical for your layout. Where the floor runs through the kitchen and living areas, staying elsewhere for part of the job is often easier. Larger homes can sometimes be staged.
Follow the written instructions for foot traffic, furniture, rugs and cleaning rather than a general waiting period. A floor can feel dry well before its coating has fully cured.
Care after your floor is finished
Use felt pads under furniture, entry mats to catch grit and the cleaning products recommended for your coating. Wipe up spills promptly and wait for the recommended curing time before laying rugs.
Our floor care guide helps with ongoing protection. Keep the selected coating details for future maintenance advice, because they determine what can be used for a recoat later.

Frequently asked questions
How do I know if my floor needs a recoat or a full sand?
A recoat may suit a floor where the existing finish is sound, compatible and only worn at the surface. If the finish has worn through, peeled or yellowed, or the timber is scratched, stained or uneven, a full sand is usually better. Jimmy assesses the boards, coating and remaining usable timber first.
Is floor sanding dusty?
We use vacuum-assisted sanding equipment that reduces dust at the source and protect doorways and adjoining areas. No sanding process is completely dust-free, so some fine dust can still settle, particularly during edge work.
Can you sand floorboards that have been under carpet?
Often, yes. Original hardwood under carpet can restore well, although staples, residue and patched sections are common. We assess the boards once the carpet is lifted, or from an exposed area, and discuss any repairs first.
Which is better, polyurethane or hard wax oil?
Neither is better in every home. Water-based polyurethane forms a hard-wearing film close to the natural timber colour; hard-wax oil gives a softer look and can often be maintained locally, but needs more regular care. The choice depends on how the room is used and the maintenance you are comfortable with.
Can I change the colour of my floor?
Usually, as part of a full sand. Natural, whitewash or limed, and darker stains are all options, but species and the age of the timber affect how colour takes. We recommend a test patch on your own floor before committing, especially with pale or very dark tones.
Can I stay at home while my floors are sanded?
It depends on your layout and the rooms included. Some homes can be staged; where the floor runs through the kitchen and main living areas, staying elsewhere for part of the job is usually more practical. We agree on this before work begins.
How many times can a timber floor be sanded?
There is no fixed number. It depends on the thickness of the boards above the tongue or fixings, how much has been removed by previous sanding and the condition of the floor. We check the remaining usable timber during the assessment.
