How much does it cost to sand and polish floorboards?

The average cost to sand and polish floorboards in a three-bedroom home is around $2,500. However, prices can vary significantly — ranging from $1,000 to $8,000 or more — depending on factors like the size of your home, the type of polish used, the condition of your timber floors, and any extra prep or repair work required.

On a per-square-metre basis, floor sanding and polishing typically costs between $35 and $90 per m², with most jobs falling between $35 and $60 per m² (plus GST). The final cost can also be affected by additional services such as:

• Floor staining or limewashing

• Water-based vs solvent-based polyurethane finishes

• Repairs to damaged boards

• Removing old floor coverings or adhesives

Each of these extras can add to your total, so it’s important to get a detailed quote tailored to your space and finish preferences.

DIY floor sanding and polishing: What does it cost?

If you’re looking for a more budget-friendly alternative, DIY floorboard sanding and polishing can significantly cut down costs — but it does require time, effort, and the right equipment.

For a simple DIY floor polish, you can spend as little as $20 on a bottle of high-quality timber floor polish to refresh the appearance of your floors temporarily.

If you’re tackling a full DIY sanding and polishing job, you’ll need to hire a drum sander and an edge sander. Here’s a rough guide to the costs:

• Floor sander hire (4–6 hours): around $40 per machine

• Full-day hire: approximately $100 per machine

• Edge sander hire: usually priced separately, similar to the drum sander

While doing it yourself can be more affordable than hiring professionals, it’s essential to follow the correct process to avoid damaging your timber floors. DIY sanding can be labour-intensive and may not deliver the same smooth, long-lasting results as a professional job — especially on older or uneven floorboards.

Different timber floor polish to choose from

When it comes to timber floor polish, there are several types to consider, each with its own benefits and best-use scenarios. The most common options are water-based polyurethane, solvent-based polyurethane, and traditional oil-based varnishes.

Here’s a breakdown of each type:

Water-based polyurethane

Ideal for areas with moderate foot traffic, water-based polyurethane is known for its quick drying time and low levels of volatile organic compounds (VOCs). This makes it a popular choice for families who need to remain in the home during the floor finishing process. It’s also more environmentally friendly and has minimal odour.

Solvent-based polyurethane

A durable and long-lasting finish, solvent-based polyurethane offers excellent protection for timber floors. However, it contains higher levels of VOCs, which can be harmful if inhaled during application. This type of polish also has a strong smell and requires proper ventilation. It’s best applied by experienced professionals.

Traditional oil-based varnishes

Still widely used across Australia, oil-based varnish is a resilient option well-suited to high-traffic areas. It provides a rich, warm tone that enhances the natural grain of the wood. The main downside is the longer drying time, which can be inconvenient if you’re on a tight renovation schedule.

Gloss levels: choosing the right finish for your floors

You can also choose from a variety of gloss levels, including:

• Matte: subtle, modern look that hides scratches well

• Satin: the most popular choice; offers a soft sheen and resists marks and scuffs

• Gloss/high-gloss: shiny and eye-catching, but shows scratches and dust more easily

Choosing the right polish depends on your lifestyle, aesthetic preference, and how much wear and tear your floors are likely to experience.

DIY floor sanding and polishing: Step-by-step guide

Thinking about polishing your timber floors yourself? While applying a timber floor polish can be a fairly straightforward DIY task, sanding floorboards is much more complex than it seems. Floor sanders are heavy, noisy, and can be difficult to control, especially for beginners. Achieving an even, professional-looking surface takes patience and skill.

It’s also important to remember that different timber types react differently to stains and polishes. For the best results, consult a timber flooring expert to ensure you’re using the right polish or stain for your floor.

If your timber floors have deep scratches, dents, or gouges, it’s strongly recommended that you hire a professional. However, if you’re confident with power tools and want to take on the challenge, follow this step-by-step guide.

What you’ll need for DIY floor sanding and polishing

Before you start, gather all the tools and materials you’ll need:

• Floor edger for sanding near skirtings

• Detail sander for corners

• Drum sander (hire)

• Sandpaper (various grits)

• Hammer and nail punch

• Dust masks and ear protection

• Heavy-duty extension cord (at least 10 metres)

• Vacuum cleaner and mop

• Large bins and bin bags

• Plastic sheets and duct tape (for sealing)

• Brush and roller with extension handle

• Timber floor polish or stain

• Sturdy footwear

• A helper — it’s not recommended to do this job alone

DIY sanding and polishing process

1. Remove the existing finish

Start by clearing the room of all furniture, curtains, wall décor, and floor coverings. Inspect the floor for protruding nails and use a hammer and nail punch to drive them 3mm below the surface. Fill any holes or dents with timber putty mixed with fine sawdust.

2. Prepare the area

Seal doorways with plastic sheets and duct tape to control dust. Open windows for ventilation and cover outlets or vents to prevent dust buildup. Ensure your work area is safe and clear.

3. Set up your sanders

Hire both a drum sander and an edge sander. Read all instructions and familiarise yourself with the machines. Check the directional arrows on the drum sander and how to load the sandpaper.

4. Load the sandpaper

Tip the sander on its side to access the drum and attach the sandpaper. You’ll need to change the sandpaper regularly throughout the process to maintain an effective sanding result.

5. Sand the main area

Begin in the centre of the room and work in even, steady motions that follow the grain of the timber. Move the sander up and down in smooth lines. Avoid jerky motions and always lift the drum before turning to prevent gouging the floor.

Vacuum and clean up dust between each sanding stage.

6. Sand edges and corners

Use the edge sander to go over skirtings and around the room’s perimeter. For tighter spaces and corners, switch to a small detail sander or sand by hand using the appropriate grit.

Make sure both the drum sander and edge sander are removing material at the same depth to achieve a consistent finish.

7. Clean thoroughly before polishing

Before applying any polish or stain, remove all dust and debris. Use a vacuum and mop to ensure the floor is clean. Any remaining dust can affect how well the polish bonds to the surface.

Applying floorboard polish

Once your timber floors have been sanded and cleaned, it’s time to apply your chosen floor polish or finish. You’ll need to decide whether to go with oil-based, water-based, or polyurethane finishes, and whether you want a matte, satin, or gloss sheen.

1. Choose your finish

Select a product that suits your practical needs and aesthetic preference. For example:

• Water-based finishes dry quickly and have low odour

• Oil-based finishes offer a rich, warm tone but take longer to cure

• Polyurethane is highly durable and comes in both solvent- and water-based formulas

If you’re staining the floor first, apply the stain before the sealer, and choose a compatible polish with your chosen stain colour.

2. Prepare the area

Ensure the room is well-ventilated and wear a protective mask, as floor finishes can release toxic fumes during application and drying. Always follow the manufacturer’s safety and application instructions.

3. Apply the first coat (sealer)

• Use a brush to cut in around the edges of the room

• Apply the finish with a roller in smooth strokes, following the direction of the wood grain

• Allow the first coat to dry fully (check the product’s drying time)

4. Lightly sand and clean

Once the first coat is dry, lightly sand the surface using a fine-grit sandpaper. This helps the next coat bond better.

• Vacuum and mop thoroughly to remove all dust before applying additional coats

5. Apply second and third coats

• Repeat the application process for the second coat

• Once dry, sand lightly again if recommended, then apply a third and final coat for improved durability and finish

A third coat helps achieve a smooth, hard-wearing surface that stands up to foot traffic and everyday wear.

Getting quotes for sanding and polishing floorboards

If you’re looking for professional help with sanding and polishing your floorboards, it’s a good idea to compare multiple quotes from local floor sanders and polishers. You can easily get free quotes through platforms like Yellow Pages. When requesting quotes, be sure to provide the following details to ensure accurate pricing:

• Total square meterage of floors requiring sanding and polishing

• Number of rooms that need attention

• Condition of the floor, including any visible damage like scratches, dents, or gouges

• Problematic areas that might require extra work (e.g. stairs, high-traffic zones)

Choosing the right professional

Beyond just price, consider the reputation and portfolio of the floor sanding and polishing company. Opt for a company with proven experience and positive reviews to ensure the job is done to a high standard. While it’s tempting to go for the cheapest option, choosing a well-regarded professional can save you money in the long run by avoiding subpar results.
