Complete Floor Sanding Guide

The Short Answer

Water-based finishes dry faster, have little odour, and stay clear over time. Solvent-based finishes take longer to dry, have a strong smell, and add a warm amber tone to the timber. Neither is universally better — the right choice depends on your timber species, lifestyle, and how much time you have.

Water-Based Polyurethane

What it looks like

Clear, bright, and clean. Shows the natural colour of the timber without adding warmth or tone. Ideal for pale timbers like Tasmanian Oak, maple, or ash where you want to keep the light, natural look.

Dry time

Light foot traffic in 2–4 hours per coat. Ready for furniture in 24–48 hours. Full cure in 5–7 days.

Coats required

Typically 3 coats — sometimes 4 on high-traffic areas or very porous timber.

Smell

Minimal. You can usually stay in the house during application (though some ventilation is recommended). Most people find the smell is gone within a few hours.

Durability

Modern commercial-grade water-based products are extremely durable — harder than most solvent-based options and resistant to scuffs, heels, and daily wear.

Best for

• Light-coloured timbers (Tasmanian Oak, spotted gum, pine)
• Households with kids or pets who need to get back on the floor quickly
• Anyone sensitive to strong chemical smells
• Apartments or homes with limited ventilation

Solvent-Based Polyurethane

What it looks like

Adds a warm, amber or honey tone to the timber. This can look stunning on darker species like blackbutt, jarrah, or brushbox — it deepens and enriches the colour. Some homeowners specifically request it for this reason.

Dry time

8–12 hours between coats. Furniture should stay off for 48–72 hours. Full cure takes 2–4 weeks.

Coats required

2–3 coats is standard.

Smell

Strong. You will need to vacate the property during application and for at least 24 hours after the final coat. Good ventilation is essential.

Durability

Very durable. Traditional solvent-based products have a longer track record, though modern water-based products have largely closed the gap.

Best for

• Darker or reddish timbers where the amber tone enhances the look
• Homeowners who prefer the traditional warm finish
• Situations where cure time is less of a concern

Side-by-Side Comparison

What About Hardwax Oils?

Hardwax oil is a third option — neither poly nor solvent in the traditional sense. It penetrates the timber rather than sitting on top as a film. The result is a natural, matte look that feels closer to bare wood.

Pros: Easy to spot-repair (sand and reapply to one area), natural appearance, good for high-character or rustic timbers.

Cons: Requires more frequent maintenance than polyurethane (re-oiling every 1–3 years depending on traffic). Does not have the protective surface hardness of poly.

Common options are penetrating hardwax oil systems available from professional flooring suppliers.

How Do I Choose?

Ask yourself:

1. What colour do I want? If you want the natural look, go water-based. If you want warmth, go solvent or hardwax oil.
2. How quickly do I need the floor back? Water-based wins hands down on turnaround.
3. Am I sensitive to smells? Water-based is the clear choice.
4. What timber do I have? Your floor sander can advise on what has worked well on similar species.

Dry vs Cured — They Are Not the Same

Dry means the surface is no longer wet to the touch — you can walk on it without leaving marks.

Cured means the finish has fully hardened to its final strength through a chemical process. A floor can feel completely dry but still be chemically soft underneath.

Damage done to an uncured floor — dragging furniture, dropping something heavy, putting down rugs too early — is permanent and usually means a re-sand or at minimum a spot repair.

Water-Based Finishes — Timeline

These are general guidelines. Always follow your tradesperson's specific advice, which will account for the product used, number of coats, temperature, and humidity.

Solvent-Based Finishes — Timeline

Hardwax Oil — Timeline

The Rug Rule

Felt Pads — Non-Negotiable

Before any furniture goes back, fit felt pads to every leg. This applies to everything — chairs, tables, sofas, beds, sideboards, appliances. Hard feet (metal, plastic, bare wood) dragged across a cured floor will scratch through the surface coating in a single pass.

Replace felt pads every 6–12 months — they collect grit and become abrasive over time.

Temperature and Humidity Matter

Cure times assume reasonable conditions (18–25 degrees Celsius, 40–60% relative humidity). In Australian summer heat (35+ degrees), water-based finishes can dry too fast and may show lap marks. In cold or humid weather, cure times extend significantly. Your tradesperson will factor this into their schedule and advice.

What Happens If I Walk on It Too Early?

Light foot traffic (socks) too early will likely leave no visible damage on a water-based finish after the first few hours. But shoes, pets, or anything with grit on the sole within the first 24 hours can leave permanent scratch marks or dull patches.

The worst case is furniture placed too early. This compresses the still-soft finish and leaves indentations or marks that are sometimes visible even after the floor has fully cured. If something does get damaged within the cure period, contact your tradesperson immediately — the sooner it is addressed, the better the options.

Overview

A professionally sanded and finished timber floor is a significant investment. With the right care it will last 15–25 years before needing a full re-sand. With the wrong care, it can look tired in 3–5 years and need costly repairs. The good news: ongoing maintenance is simple and mostly involves a few consistent habits.

Daily and Weekly Care

Sweep or vacuum regularly

Grit and sand particles are the enemy. They act like sandpaper underfoot and scratch the surface coating with every footstep. A quick sweep or vacuum (on hard-floor setting — not the beater bar) every few days makes a dramatic difference to long-term wear.

Use a damp mop, never a wet one

Excess water damages timber floors — it lifts grain, causes swelling, and degrades the finish. A microfibre mop wrung almost dry is ideal. Use a dedicated timber floor cleaner — these are formulated specifically for finished timber and leave no residue.

Clean spills immediately

Water, wine, oil — anything liquid should be wiped up straight away. Even waterproofed floors are not impermeable to sustained moisture sitting on the surface.

What to Avoid

• Steam mops — the combination of heat and moisture forces water through the finish and into the timber. Causes irreversible damage over time.
• Ammonia-based or oil-based cleaners — strip the finish and leave a residue that prevents proper adhesion if you ever need a recoat.
• Vinegar and water solutions — acidic, dull the finish over repeated use.
• Spray and shine products — leave a waxy or oily film that hides the finish and makes maintenance recoats fail to bond.
• High heels — stilettos exert more pressure per square centimetre than a forklift tyre. There is no finish that is fully immune.
• Dragging furniture — always lift, never drag.

Protecting High-Traffic Areas

Felt pads on all furniture legs

Replace every 6–12 months as they accumulate grit.

Door mats at entries

A mat inside and outside every exterior door catches grit before it hits the floor. This single habit extends finish life significantly.

Rugs in heavy-wear zones

Hallways, in front of sofas, and kitchen/dining areas all benefit from a quality rug. Ensure rugs have a breathable backing — not rubber or PVC, as these trap moisture and cause yellowing or finish damage.

Sunlight protection

UV exposure yellows lighter timbers and fades darker species. Use blinds or UV-filtering window film in rooms with strong direct sunlight.

Maintenance Recoat (Screen and Recoat)

A maintenance recoat — sometimes called a screen and recoat — is the single best thing you can do to extend the life of your floor without a full re-sand.

It involves:

1. Lightly abrading (screening) the existing finish to give the new coat something to bond to
2. Applying 1–2 fresh coats of finish over the existing surface

When to do it: Every 5–8 years, or when the floor starts looking dull or worn in high-traffic areas but has no deep scratches or bare patches.

Important: This only works if the floor surface is clean and free of oil-based products, wax, or polish. Contaminated surfaces will not bond. Tell your tradesperson what cleaning products you use so they can assess adhesion before quoting.

Addressing Scratches

Surface scratches (in the finish, not the timber)

Normal and expected over years of use. A maintenance recoat will cover minor surface scratches.

Deep scratches (into the timber)

Require spot sanding and spot finishing, or a full re-sand depending on depth and number. Address them before they allow moisture or dirt into the timber grain.

Dents and indentations

Timber has natural memory — shallow dents can sometimes be raised with a small amount of moisture (a damp cloth left on the dent for a few minutes). Deep dents or gouges generally require filler or a board replacement.

Pet Ownership

• Keep nails trimmed — long nails are the number one cause of floor damage from pets
• Water bowls on a mat — dogs and cats splash
• Vomit, urine, and faeces should be cleaned immediately — the acids can permanently stain or damage the finish and the timber underneath
• Consider harder finishes (commercial-grade water-based products) in homes with multiple pets

Summary Checklist

• Sweep or vacuum (hard-floor setting) every 2–3 days in high-traffic areas
• Damp mop weekly with a dedicated timber-safe cleaner
• Felt pads on all furniture — check and replace every 6–12 months
• Door mats at all entries (inside and outside)
• Rugs in high-wear zones with breathable backing
• No steam mops, no ammonia cleaners, no wax or oil polish
• Spills wiped up immediately
• Plan for maintenance recoat every 5–8 years
• Trim pet nails regularly

Overview

For most people, having their floors sanded is not a regular occurrence. Knowing what is going to happen, how long it will take, and what to expect during and after the job removes a lot of the stress. Here is the full picture.

Before the Job

Book a consultation

A good floor sander will inspect the floor in person before quoting — checking the timber species, condition, thickness of existing boards, any previous finishes, subfloor type, and any repairs needed. Photos are useful for a rough estimate but no reputable tradesperson should price a large job sight-unseen.

Discuss the finish

Before the job starts, confirm your finish choice (water-based or solvent), sheen level (matte, satin, semi-gloss, or gloss), and any staining if required. Changing your mind mid-job is costly and sometimes impossible.

Organise alternative accommodation (solvent-based jobs)

If your tradesperson is using solvent-based polyurethane, the smell is strong enough that most households with children, elderly residents, or anyone with respiratory sensitivities should plan to stay elsewhere for at least 24 hours after the final coat. Water-based products are significantly better in this regard.

Move furniture out

Everything needs to come off the floor — all furniture, rugs, and loose items. Curtains and blinds that hang to the floor should also be removed or tied up to avoid contact with the sander.

Day One — Preparation and First Sand

Arrival

The crew will arrive with commercial drum or belt sanders, edge sanders, detail sanders, and dust extraction equipment. Expect noise — floor sanding is loud. If you are working from home, it is worth planning for this.

Dust

Modern professional equipment uses dust extraction bags and vacuum systems. The job is not dust-free but significantly less dusty than older equipment. Fine dust can still spread — close doors to rooms not being sanded, and be aware that electrostatics can carry fine particles onto surfaces some distance away.

The first cut

The first sanding pass is the most aggressive — removing the old finish, levelling uneven boards, and preparing the surface for the finer grits. The floor will look raw and stripped at this stage. This is normal.

Gaps and repairs

After the first cut, any board repairs, nail punching, and gap filling will be done. Flexible filler goes into cracks and gaps and needs to dry before the next stage.

Mid-Process — Sanding Stages

Floor sanding proceeds through multiple grits — starting coarse and finishing fine. Each pass smooths the scratches left by the previous grit. A properly sanded floor goes through at least 3–4 grit stages before the finish goes on. Rushing this process by skipping grits results in a finish that shows scratch lines under light — the difference is very visible.

After the final sanding pass, the floor is vacuumed and tacked (wiped with a tack cloth) to remove every particle of dust before the first coat of finish.

Coating Days

First coat

Applied by roller, brush, or spray depending on the product and area. The floor is blocked off — no foot traffic at all while wet.

Between coats

The floor is lightly sanded (abraded) between coats with a fine screen or abrasive to knock back any raised grain or dust nibs and ensure adhesion of the next coat. This is normal — it does not mean the coat was bad.

Final coat

Applied and left to cure. The crew will advise on the exact timeframe for when you can re-enter.

How Long Does the Job Take?

A standard house (3–4 bedrooms, 80–120 sqm of flooring) typically takes:

Larger or more complex jobs (herringbone parquetry, extensive repairs, staining) take longer. Small jobs (single room, one-coat maintenance) can be done in a day.

The Floor After the Job

It will look different — in a good way

Raw timber straight after sanding often looks paler or different in colour to what the finished result will be. Once the finish goes on, the colour and grain depth really show. Most people are pleasantly surprised.

Grain raise is normal

Water-based products cause a slight raising of the grain on the first coat — this is why there is a sanding step between coats. The final result is smooth.

Colour variation between boards is normal

Timber is a natural product. Different boards will absorb the finish differently and show different grain patterns. This is character, not a defect.

After the Crew Leaves

• The tradesperson will tell you exactly when you can walk on the floor and when furniture can go back
• Follow the cure time guidance — see the Cure Times guide for full details
• Do not lay rugs for at least 2 weeks (water-based) or 4 weeks (solvent)
• Fit felt pads to all furniture before it goes back
• Use a timber-safe cleaner for the first clean — no steam mop, no ammonia, no vinegar

Common Questions

Can I stay in the house while the job is happening?

Usually yes for water-based, with some inconvenience (noise, some dust, inability to use the floor area). For solvent-based, most people with children or health sensitivities choose to stay elsewhere during application.

What happens if it rains?

Humidity affects cure times and, in extreme cases, how the finish lays. A professional crew will monitor conditions and adjust scheduling if needed.

What if I find a problem after the job is done?

Contact your tradesperson promptly. Most issues raised within a few days of job completion (uneven areas, marks, drips) can be addressed. The longer you wait, the harder the fix.

Furniture

Remove everything from the floor area

This includes all furniture, rugs, floor lamps, pot plants, and any loose items. The floor must be completely clear before sanding can begin.

Where to put it

• Rooms not being sanded (if any)
• Garage, shed, or outdoors if weather allows
• Storage unit for a few days if the whole house is being done

Heavy items like pianos, built-in wardrobes, and whitegoods should be arranged in advance. If you are unsure, ask when booking.

Floor Preparation

Carpet removal

Remove all carpet and underlay if you are having existing carpet taken up — or have this done separately beforehand. Bay's offers carpet and staple removal as a service if you would like it handled as part of the job.

Nail heads

Any nail heads proud of the surface should be punched below the surface before sanding begins. High nails will tear the sanding belt and leave marks. If you are unsure, we will check and punch as part of the job.

Known repairs

Tell us about any known issues — loose boards, squeaky boards, damaged sections — so we can quote and schedule appropriately. Surprises on the day add time and cost.

Cleaning Before the Job

A general vacuum beforehand to remove surface dust, grit, and debris is helpful. The area does not need to be spotless — the sanding process will handle the rest — but large debris should be cleared.

The Rest of the House

• Close doors to adjacent rooms to minimise dust travel to areas not being sanded
• Remove or tie up curtains and blinds that hang to floor level — the sander can catch light fabrics
• Cover sensitive electronics (TVs, computers, sound equipment) in adjacent areas with a dust sheet
• Take down wall art immediately adjacent to the floor area — vibration from the sander can loosen hanging items

Access

• Clear parking near the entry — equipment is heavy and there will be multiple trips in and out
• Access to a power point — commercial sanders draw significant power. A standard 10A GPO is fine
• Key access if you will not be home — arrange this in advance so we can enter, work, and lock up

Alternative Accommodation

If we are using solvent-based polyurethane, or if you or anyone in the house has respiratory sensitivities, plan to stay elsewhere during application and for the period advised after the final coat (typically 24 hours minimum, longer for sensitive individuals).

Water-based finishes are much more manageable — most people can return within a few hours of the final coat, though ventilation is still recommended.

Pets should be kept out of the work area during sanding and coating. Fur and hair settle in wet finish and are very difficult to remove cleanly.

On the Day

• Have your finish choice confirmed before the crew arrives (water-based or solvent-based, sheen level)
• Have a contact number available if the crew needs to reach you
• Let us know of any specific concerns about particular boards or areas
• Secure pets away from the work area

Preparation Checklist

• All furniture removed from sanding area
• Rugs and floor coverings removed
• Carpet and underlay removed (if applicable)
• Curtains and blinds tied up or removed
• Sensitive electronics covered
• Finish choice confirmed (water-based or solvent, sheen level)
• Key access arranged if you will not be home
• Alternative accommodation arranged (solvent-based only)
• Pets secured away from the work area
• Parking space cleared for the crew vehicle

If you are unsure about anything, call us before the job — not on the day. Most preparation questions take 30 seconds to answer and save hours of hassle.

Quotes and Pricing

How much does floor sanding cost?

Floor sanding is priced by the square metre and varies significantly based on the condition of the floor, the type of finish, number of coats, any repairs required, and accessibility. A basic sand and two-coat finish on a clean residential floor starts from around $25–$40 per sqm. Heavily damaged floors, intricate repairs, or complex layouts (herringbone, parquetry) will be at the higher end. The only reliable way to get an accurate price is an in-person quote.

Do you charge for a quote?

No. Quotes are free and there is no obligation.

Why is my quote different from what I found online?

Online per-sqm figures are rough guides only. They do not account for the current condition of your floor, the type of timber, what finish you have chosen, or whether any repair work is needed. An in-person look is the only way to give you an accurate price.

Can I get a quote from photos?

We can give you a rough ballpark from photos but we will not provide a firm price without seeing the floor. Too many variables are invisible in a photo — board thickness, previous finish type, subfloor condition.

The Job Itself

How long does the job take?

A standard 3–4 bedroom house (80–120 sqm) typically takes 3–4 days from start to final coat. Single rooms can be done in a day. Large commercial jobs or complex repairs will take longer.

Do I need to move out?

For water-based finishes: no. Inconvenience yes, but most households can manage. For solvent-based: we strongly recommend vacating for at least 24 hours after the final coat, particularly for children, elderly people, or anyone with respiratory conditions. Pets should be kept out during the work regardless of finish type.

How dusty is it?

Modern professional sanders use dust extraction systems — the job is significantly less dusty than sanding by hand. However, fine dust does travel, particularly to adjacent rooms. Close doors, cover sensitive electronics, and give the house a good clean after we are done.

Can you sand floors that have carpet glue or adhesive on them?

Yes. Glue, adhesive, and subfloor residue from carpet removal are manageable, though they add time and may affect the quote. Let us know upfront so we can factor it in.

Do you work on stairs?

Yes. Stairs require edge sanders and hand sanding — they take more time per sqm than open floor areas and are priced accordingly.

Timber and Finishes

What types of timber can be sanded?

Most solid hardwood and engineered hardwood flooring can be sanded. Solid timber can usually be sanded multiple times over its life. Engineered timber has a wear layer and can typically be sanded 2–3 times depending on thickness. Laminate and hybrid flooring cannot be sanded — they are a printed surface over a composite core.

Can I change the colour of my floor?

Yes, with stain. Staining adds a step to the process and narrows your choice of topcoat (some stains are not compatible with all finishes). Going darker is generally more forgiving than going lighter. Stain samples should be tested on an inconspicuous area before committing.

What sheen level should I choose?

• Matte: Hides foot traffic marks and everyday scuffs well. Natural, contemporary look. The most forgiving in busy households.
• Satin: The most popular choice. A subtle sheen that looks clean without being glassy.
• Semi-gloss / Gloss: Reflective and dramatic. Shows foot traffic, pet scratches, and dust more readily. Better suited to formal spaces or low-traffic areas.

Can you match an existing finish?

Roughly, yes. Exact matching is difficult — the existing finish has aged, been worn, and may be a discontinued product. We can get close on sheen level and colour but a perfect invisible join between old and new is rarely possible.

Repairs and Damage

My floor has gaps between boards. Can they be fixed?

Small gaps are normal timber movement and can be filled with flexible filler as part of the sanding process. Large or structural gaps (boards that have moved significantly due to subfloor movement or moisture) may require board replacement or a subfloor assessment.

Can individual boards be replaced?

Yes. We can replace damaged boards and blend them into the surrounding floor. How visible the repair is depends on the age and patina of the surrounding boards — new timber rarely matches perfectly at first but weathers over time.

Can squeaky floors be fixed?

Sometimes. Squeaks caused by boards rubbing against each other or against nails can be addressed during the sanding process. Squeaks caused by subfloor movement, bearer issues, or structural problems are outside the scope of a sand and polish job.

After the Job

How long before I can put furniture back?

For water-based: light furniture with felt pads can go back after 48 hours. Full weight after 5–7 days. For solvent-based: 48–72 hours minimum, heavier loads after 7–14 days.

When can I put rugs down?

Water-based: minimum 2 weeks. Solvent-based: minimum 4 weeks. Rugs trap moisture during the curing process and can cause permanent marks in the shape of the rug if placed too early.

How do I clean the floor after the job?

A dry sweep or vacuum (hard-floor setting) first. Then a barely damp microfibre mop with a dedicated timber-floor cleaner. No steam mops, no ammonia-based products, no vinegar, no wax or oil polish.

How long will the finish last?

In a typical residential home, a quality finish lasts 8–15 years before it looks significantly worn. In high-traffic or commercial areas, 5–8 years. A maintenance recoat every 5–8 years will significantly extend this timeline without needing a full re-sand.

What is a maintenance recoat?

A light abrasion of the existing finish followed by 1–2 fresh coats — no sanding of the timber itself. It refreshes the protective layer and dramatically extends floor life. Only works if the floor surface is clean and uncontaminated.

Booking

How far in advance do I need to book?

During busy periods (spring renovation season, end of year) we can be booked out 4–6 weeks. At quieter times, 1–2 weeks is usually enough. Larger jobs benefit from more lead time.

What areas do you service?

We service the full Central Coast region including Summerland Point, Gosford, Wyong, Tuggerah, The Entrance, Terrigal, Bateau Bay, and surrounds, as well as Lake Macquarie and the Hunter Valley. Contact us to confirm your area.

Do you do small jobs?

Yes. A single room, a hallway, or a maintenance recoat — all are welcome.
